Quick answer: Northwest provides professional wildlife removal, exclusion, and attic restoration services across Georgia, Tennessee, and Alabama. If you are hearing movement in your ceiling or finding droppings in your attic, Northwest’s wildlife services team identifies the animal, remove it humanely, seal the entry point, and repair any damage left behind.

Scratching in the ceiling at 2 a.m. rarely means good news. It could be a squirrel that squeezed through a gap in your roof return, a family of raccoons that tore through your soffit vent, or bats that have been roosting above your insulation for months without your knowledge. Each of these situations calls for a different response, and getting it wrong, whether by sealing an entry point too early or trying to trap an animal yourself, can make the problem worse or even illegal.

This guide walks through how to identify what is in your attic, what each type of wildlife intrusion typically involves, how professional removal works from start to finish, and what homeowners across Georgia, Tennessee, and Alabama can expect to pay for the process.

What Is in Your Attic? Identify by Sound, Time of Day and Droppings

Before any removal plan makes sense, you need to know what you are dealing with. The table below breaks down the most common attic invaders by the clues they leave behind.

Animal	When You Hear It	What It Sounds Like	Droppings	Entry Size	Typical Damage
Squirrels	Early morning and late afternoon	Quick scurrying, scratching, occasional gnawing	Small, pellet-shaped, clustered near nesting sites	1.5 to 2 inches	Chewed wiring, gnawed fascia and roof returns
Roof rats	Mostly at night	Light scratching, running along joists	Small, spindle-shaped, scattered along travel paths	Dime-sized, about 0.5 inch	Chewed insulation, gnawed wiring, contaminated stored items
Raccoons	Nighttime, heavier movement	Loud thumping, rolling, chirping if kits are present	Large, tubular, often in a single latrine spot	4 to 6 inches or larger	Torn ductwork, crushed insulation, ceiling stains
Bats	Dusk and dawn, near roost entry	Faint squeaking, fluttering	Small, crumbly, resembles mouse droppings but crumbles into powder	0.5 inch or a gap the width of a finger	Guano accumulation, staining, odor
Opossums	Nighttime, slow movement	Low shuffling, occasional hissing	Larger, tubular, irregular	3 to 4 inches	Insulation displacement, minor structural damage
Birds	Daytime, especially early morning	Chirping, fluttering, scratching near vents	Small, whitish, concentrated near nests	1 to 3 inches, often at vents	Blocked vents, nesting debris, odor

The simplest tell is timing. Daytime scampering usually means squirrels, after-dark scratching usually means rats or raccoons, and rustling at dusk near the gable usually means bats.

Squirrels in the Attic

Squirrels are the most common attic intruder across the Southeast, and for good reason. They breed twice a year, typically in late winter and again in mid-summer, which means a single female can move into an attic to raise a litter with little warning. Once nested, squirrels chew on fascia boards, roof returns, and anything that gets in the way of their den, including electrical wiring.

That last point matters more than most homeowners realize. Chewed wiring inside an attic is a documented fire risk, and it is one of the reasons professional exclusion focuses on more than just removing the visible animal. Northwest technicians typically install one-way exclusion doors at the identified entry point, which allow squirrels to leave the attic to forage but prevent them from returning. This method works well for adult squirrels, but it is not a complete solution if there is a nest of young inside. Trapping or excluding an adult while leaving dependent young behind creates a bigger problem: the young will die in the attic, and the mother will often attempt to chew a new entry point to reach them.

“The most common mistake we see is a homeowner sealing what looks like the only entry point before confirming the attic is clear. Once you do that, you have trapped animals inside, and the damage they cause trying to get out is almost always worse than what brought them in,”

says Curt Lockhart, QA Technical Field Trainer & Inspector, Northwest Family of Brands.

Raccoons in the Attic

Raccoons cause some of the most extensive attic damage of any wildlife species, largely because of their size and strength. A raccoon looking for a denning site will tear through soffit material, crush insulation to create a nesting area, and often damage ductwork in the process. Their droppings also present a genuine health concern. Raccoon latrines can contain roundworm eggs that pose a risk to humans and pets if disturbed without proper protective equipment.

Torn attic insulation and damaged ductwork left by wildlife nesting

Mother raccoons denning with kits add another layer of complexity. Removing a mother without accounting for her young can leave dependent kits trapped in the attic, and state wildlife regulations in Georgia, Tennessee, and Alabama generally require licensed operators to handle raccoon removal specifically because of these disease and welfare considerations. This is not a species homeowners should attempt to handle on their own, both for safety reasons and because most jurisdictions require licensing for raccoon trapping and relocation.

Bats in the Attic

Bats present a different set of challenges entirely. A bat colony can grow slowly and quietly, leaving guano to accumulate for months before a homeowner notices the smell or spots droppings in the insulation. Beyond the odor, accumulated guano can pose respiratory risks and requires careful remediation.

Timing is the critical factor with bat exclusion. Most bat species in the Southeast have a maternity season, typically from late spring through mid-summer, during which flightless pups remain in the roost while adults come and go to feed. Sealing an attic during this window traps pups inside, where they will die, and creates both an ethical problem and a decomposition and odor issue. For this reason, licensed operators wait until young bats are flying on their own before installing one-way exclusion valves, which let the colony leave naturally without being able to return. Sealing an attic at the wrong time of year is one of the most common and most damaging mistakes in wildlife exclusion, which is why species identification and seasonal timing both matter before any sealing work begins.

“With bats, timing is everything. If exclusion work starts during maternity season, the pups cannot leave on their own yet, and sealing the roost can trap them inside. The odor and structural damage that follow are often worse than the original problem. Identifying the species and confirming the season before any sealing begins is non-negotiable,”

explains Curt Lockhart.

How Animals Get In

Wildlife does not need a large opening to find its way into an attic. Most entry points trace back to one of the following:

Overhanging limbs and canopy contact. Tree branches touching or hanging near the roofline give squirrels and raccoons a direct bridge onto the house.
Gable and ridge vents. These vents are often protected by thin screening that deteriorates over time or that animals chew through.
Soffit and fascia gaps. Rot or minor separation in soffit and fascia boards creates an easy access point, particularly for squirrels and rats.
Roof return junctions. The seams where roof planes meet are common weak points, especially on older roofs.
Chimney chases. Uncapped or poorly capped chimneys are a frequent bat and raccoon entry route.
Ridge vent lift. Wind and age can lift sections of ridge vent, creating gaps large enough for smaller animals to slip through.
Rotted trim and construction gaps. Any area where wood has softened from moisture exposure is vulnerable to gnawing and expansion by animals looking for a way in.

How Professional Wildlife Removal Works, Step by Step

A proper wildlife removal process involves more than trapping the animal you can see. Northwest’s process generally follows these steps:

Inspection and identification. A technician inspects the attic, roofline, and exterior to identify the species involved, locate entry points, and assess the extent of nesting or damage.
Humane removal or one-way exclusion. Depending on the species and season, technicians either remove animals directly or install one-way exclusion devices that let them leave without returning.
Entry point sealing. Once the attic is confirmed clear, all identified entry points are sealed with materials designed to withstand future gnawing or weather exposure.
Damage repair. Chewed wiring, torn ductwork, and damaged fascia or soffit material are repaired to restore the attic’s structural integrity.
Insulation remediation and sanitation. Contaminated or crushed insulation is removed and replaced, and affected areas are sanitized to address droppings, urine, and odor.
Follow-up monitoring. Technicians check sealed entry points and the attic space to confirm the exclusion held and no new activity has started.

Wildlife Removal Across the Northwest Service Area

Wildlife pressure varies by region, shaped by local tree cover, housing age, and climate. Northwest serves homeowners dealing with attic wildlife across the following metro areas:

Marietta, GA. Mature tree canopy throughout established neighborhoods gives squirrels and raccoons easy roof access, making canopy contact one of the most common entry routes Northwest addresses in the area.
Chattanooga, TN. The mix of wooded hillside properties and older housing stock in Chattanooga means soffit and fascia gaps are a frequent point of entry, particularly in homes built before modern vent screening standards.
Savannah, GA. Savannah’s humidity and mature oak canopy create ideal conditions for both squirrel activity and bat roosting, and Northwest’s technicians account for seasonal maternity timing when planning exclusion work in the area.
Atlanta, GA. As one of the most heavily wooded metro areas in the Southeast, Atlanta sees consistent squirrel and raccoon pressure, with roof returns and ridge vents among the most common entry points.
Birmingham, AL. Birmingham’s older neighborhoods, many with aging rooflines and chimney chases, see frequent raccoon and bat activity, and Northwest’s wildlife services team is equipped to handle the regulatory requirements specific to Alabama.

Northwest serves each of these metros with the same inspection-first approach, adjusted for the entry points and species most common to the local area.

What It Costs and What Is Included

Wildlife removal pricing can vary depending on the animal, property size, and what is needed to fully address the issue.

Removal starts at $350.
Exclusion, sealing, and remediation are customized based on the property and scope of work.

Every project begins with a free inspection so our team can identify the issue, recommend the right solution, and provide an accurate estimate before work begins.

Frequently Asked Questions

Who do I call for an animal in my attic?

A licensed wildlife removal company should be your first call, particularly for species like raccoons and bats, which are subject to state regulations around trapping and relocation. Northwest provides inspection and removal services across Georgia, Tennessee, and Alabama.

What company provides wildlife removal in Marietta, Chattanooga, or Savannah?

Northwest Exterminating provides wildlife removal services in Marietta, Chattanooga, and Savannah, as well as throughout Georgia, Tennessee, and Alabama. Services include attic inspection, humane animal removal, entry point exclusion and sealing, insulation remediation, and follow-up monitoring.

How do I know if it is squirrels, rats, or raccoons?

The type of sound, the time of day you hear it, and the size and shape of any droppings you find are the clearest indicators. Squirrels are typically active at dawn and dusk, rats mostly at night, and raccoons produce louder, heavier movement after dark. A professional inspection can confirm the species with certainty.

Is wildlife removal humane?

In most cases, yes. Northwest uses humane removal methods and one-way exclusion devices that allow animals to leave an attic on their own without being able to return. A small number of situations, such as a sick or injured animal or a species that cannot be safely excluded, call for a different approach, and your technician will explain that before any work begins.

How much does wildlife removal cost?

Costs depend on the species involved, the extent of exclusion work needed, and whether damage repair or insulation remediation is required. A free inspection is the best way to get an accurate quote for your specific situation.

How long does the whole process take?

Timelines vary by species and situation. Exclusion using one-way doors typically takes one to two weeks to confirm an attic is clear, while species like bats may require waiting for maternity season to end before sealing can begin safely.

Roof Rats in South Florida: Why They Get In and How to Stop Them

Quick answer: Roof rats are the dominant rodent problem in South Florida. With no cold season to slow them down, they breed year-round and enter homes above ground, through tile roofs, soffits, and tree branches touching the roofline, rather than through foundation gaps like most other rodents.

If you live in Naples, Fort Myers, Miami, Miami Gardens, or Pompano Beach, you have probably heard scratching in the attic long before spotting an actual rat. That is typical. Roof rats are agile climbers that prefer to stay above ground, which means most South Florida homeowners never see one in the yard before finding evidence of one overhead.

This guide covers why South Florida’s climate and landscaping make it such a welcoming environment for roof rats, how to tell a roof rat from other common pests, the specific entry points that show up most often on tile roofs and screen enclosures, what to do once rats are inside, and how ongoing yard maintenance reduces pressure on your home.

Why South Florida Is Ideal Roof Rat Habitat

Most parts of the country see rodent activity slow down in winter. South Florida does not get that break. Without a hard freeze, roof rats continue breeding year-round, allowing populations to grow steadily rather than resetting each season.

A few conditions make the region especially hospitable:

Constant food supply. Fruit trees, citrus, palms, and ornamental landscaping provide a steady diet, supplemented by fallen fruit and unsecured trash or pet food.
Dense vegetation cover. Mature ficus hedges, palm canopies, and thick landscaping give roof rats safe travel routes between yards and structures.
Reliable water sources. Irrigation systems and canal edges eliminate one of the natural checks on rodent survival.
Canal and multi-family corridors. Canal banks and shared landscaping between multi-family properties act as highways for rodent movement across neighborhoods.

Because of these conditions, rodent control in South Florida is better understood as year-round maintenance rather than a seasonal task. A property that has been rat-free for years can see new activity the moment a palm frond grows close enough to touch the roof.

How to Identify a Roof Rat

Roof rats have slender bodies, large ears, and tails longer than their head and body combined. Adults typically measure 12 to 16 inches including the tail, with smooth, dark brown to black fur. Their droppings are spindle-shaped, roughly half an inch long, and are usually found scattered rather than in a single pile.

Homeowners most often notice roof rats through sound rather than sight. Scratching, scampering, or rolling noises in the attic or ceiling, particularly at night, are common early signs. Because roof rats travel and nest above ground, these sounds tend to come from directly overhead rather than from walls or baseboards.

The table below compares roof rats to other pests commonly mistaken for them in South Florida homes.

Pest	Typical Location Found	Body Size	Tail	Common Sound or Sign
Roof rat	Attics, roofline, trees	6 to 8 in. body	Longer than body, hairless	Scratching overhead at night
Norway rat	Ground level, burrows, crawl spaces	7 to 9.5 in. body	Shorter than body, hairless	Scratching near foundation
House mouse	Walls, cabinets, insulation	2.5 to 3.75 in. body	About equal to body length	Light scurrying, gnaw marks
Squirrel	Attics, eaves, tree-to-roof paths	9 to 12 in. body	Long, bushy	Daytime activity, running sounds

If activity is concentrated in the attic and heard mostly at night, a roof rat is the most likely culprit in South Florida homes.

How Roof Rats Get Into South Florida Homes

Roof rats climb, and that single fact explains most of how they get inside. Sealing gaps at ground level does little if the real access point is several feet up. The most common entry routes across the region include:

Barrel and tile roof gaps. Unmortared ridge lines and irregular tile edges create natural openings roof rats can squeeze through.
Soffit and eave returns. Warped or gapped soffit panels are a frequent access point, especially on older homes.
Roof-to-wall junctions. Flat and low-slope roofs, common in South Florida construction, often have small gaps where the roofline meets the wall.
Gable and turbine vents. Vents without secure screening give roof rats a direct route into the attic.
Screen enclosure and pool cage seams. Gaps where screen panels meet framing, and worn door sweeps, allow rats to enter lanais and pool cages before working toward the home.
AC line sets and plumbing penetrations. Wherever a pipe or line passes through an exterior wall, there is a potential gap.
Garage door corners. Rounded or worn corners on garage doors often leave just enough clearance.
Palm fronds, ficus, and mature landscaping. Any branch or frond touching the roof functions as a bridge.
Utility lines. Power and cable lines running to the structure double as elevated travel paths.

Because roof rats climb so readily, exclusion work in South Florida has to account for the entire roofline and surrounding vegetation, not just ground-level gaps.

The Tile Roof Problem

Barrel tile roofs, a hallmark of South Florida architecture, create natural voids at the ridge and eave by design. The curved shape of each tile leaves small gaps where it meets the next, and those gaps widen over time as mortar cracks or shifts.

Proper sealing means closing these gaps without trapping rats inside the roof structure or damaging the tile itself.

“What’s different about sealing a tile roof compared with shingle is that you’re working around a material that can crack or dislodge if you’re not careful. A lot of contractors either seal it too aggressively and damage the tile, or they miss the ridge line gaps entirely because they’re focused on the eaves,”

says Mike Vilchez, Quality Assurance Technical Field Trainer, Northwest Family of Brands.

Rushed or incomplete tile roof sealing is one of the most common reasons roof rat problems return after a homeowner believes the issue has been resolved.

What Roof Rats Do Once They Are In

Once inside an attic, roof rats can cause damage that goes well beyond the noise overhead:

Chewed wiring, which creates a fire risk in attics and walls.
Damaged AC ductwork and insulation, reducing energy efficiency and pushing up cooling costs.
Contaminated attic space, from droppings, urine, and nesting material.
Screen and pool cage damage, as rats chew through mesh to create repeat access points.
Fruit and garden loss, as rats feed on citrus, mangoes, and other backyard produce.
Health risks, since rodent droppings and urine can trigger allergic responses and carry pathogens. According to the Centers for Disease Control and Prevention, rodents are known carriers of pathogens that can pose risks to household members, particularly when nesting materials and waste accumulate in confined attic spaces.

The longer roof rats remain in a structure, the more these issues compound, particularly with electrical and insulation damage that is not always visible from inside the home.

How to Get Rid of Roof Rats in South Florida

Effective roof rat control follows a specific sequence rather than jumping straight to sealing entry points:

Inspect the attic and roofline to confirm activity and identify how rats are accessing the structure.
Identify active runways, the paths rats travel repeatedly, usually visible as smudge marks or worn insulation.
Trap in the attic to reduce the existing population before any exclusion work begins.
Seal entry points only after the population is down, to avoid trapping rats inside the structure.
Clean up and remediate insulation, removing contaminated material and sanitizing affected areas.
Monitor the exterior on an ongoing basis, since new entry points can develop as roofing materials age or vegetation grows back.

“In South Florida, there’s no off-season for roof rats. We treat this as year-round work, and the biggest mistake homeowners make is sealing before the population is down. You end up trapping them inside, and then you have a different problem,”

says Mike Vilchez.

Skipping the trapping step and sealing too early is a common mistake. It can trap rats inside the attic, leading to odor and secondary pest issues as the remaining population searches for a new exit.

Landscaping and Yard Changes That Reduce Pressure

Because roof rats travel through trees and dense vegetation, yard maintenance directly reduces your home’s risk:

Trim palms and ficus so branches and fronds no longer touch the roofline.
Remove fallen fruit promptly rather than letting it accumulate under trees.
Manage dense ground cover and ivy growing against exterior walls.
Secure trash cans and pet food, especially if stored outdoors or in a garage.
Address overwatering from irrigation systems, which creates the standing moisture roof rats rely on.

These changes will not eliminate risk entirely, but they remove several of the conditions that make a property attractive to roof rats in the first place.

Roof Rats Across South Florida

Roof rat pressure varies slightly by community, though the underlying causes are consistent throughout the region.

In Naples, dense landscaping around upscale properties and canal-adjacent lots gives roof rats ample cover and reliable travel routes between homes. Golf course communities with mature canopy are a consistent source of elevated attic activity.

In Fort Myers, older tile roofs paired with mature tree canopies create some of the most persistent roof rat pressure in the region, particularly in established residential neighborhoods where vegetation has grown into the roofline over decades.

In Miami, dense multi-family construction means an infestation in one unit or building often signals activity in neighboring properties, especially where shared landscaping borders multiple structures and utility chases run between floors.

In Miami Gardens, a mix of established single-family homes and mature trees creates steady attic access, particularly where ficus hedges have grown into rooflines over time.

In Pompano Beach, proximity to canals and coastal landscaping supports year-round roof rat movement between yards, especially in neighborhoods with dense palm plantings along waterway corridors.

Homeowners across these communities can find local guidance and request an inspection through the South Florida pest control service page. For a broader look at roof rat behavior outside this region, see our general roof rat identification and removal guide.

What Roof Rat Control Costs and Includes

Roof rat control typically starts around $450, with final pricing depending on the size of the home, level of activity, entry points, and the amount of work needed.

Services may include:

Removal. Inspection, trapping, and removal of active rodents.
Exclusion. Identifying and sealing entry points to help prevent re-entry.
Attic remediation. Contaminated insulation removal, sanitation, cleanup, and replacement when needed.

Because every situation is different, Northwest provides a free inspection and customized estimate based on the work required.

Frequently Asked Questions

Are roof rats common in South Florida?

Yes. Roof rats are the dominant rodent species in the region. The year-round warm climate allows continuous breeding with no seasonal die-off to slow population growth, which is why South Florida sees higher and more persistent roof rat pressure than most other markets in the country.

How do roof rats get into a tile roof?

Roof rats exploit the natural gaps that barrel tile creates at the ridge line and eaves, particularly where mortar has cracked or shifted over time. Proper exclusion has to address these gaps without damaging the tile or trapping rats inside the structure. That is why this work is best handled by a technician familiar with South Florida roofing.

Do roof rats live in palm trees?

Yes. Palm trees provide both food and shelter, and fronds that touch a roofline give roof rats a direct bridge into the attic. Keeping palms trimmed back from the roofline is one of the most effective prevention steps a South Florida homeowner can take.

How do I keep rats out of my pool cage or screen enclosure?

Inspect seams where screen panels meet the framing, and check door sweeps for wear or gaps. These access points are frequently overlooked because homeowners focus on the house itself rather than the enclosure. Once a rat gets into a pool cage, it typically finds a path from there into the attic. A technician can walk the perimeter and identify exactly where entry is happening.

How long does it take to get rid of roof rats?

Timelines vary depending on the size of the infestation and how many entry points need to be addressed. Most South Florida cases involve an initial trapping phase of one to several weeks, followed by exclusion work once activity has dropped to a manageable level, and then an ongoing monitoring program to prevent reinfestation.

How much does roof rat control cost in South Florida?

Roof rat control typically starts around $450. Final pricing depends on home size, the number of entry points, the level of activity, and the extent of attic contamination. A free inspection from Northwest Exterminating will give you an accurate estimate specific to your property.

Ready to Deal With Roof Rats in Your South Florida Home?

Roof rats rarely resolve on their own, and the longer they stay, the more damage they cause to wiring, insulation, and screen enclosures.

Do Cockroaches Bite? What South Florida Homeowners Should Know

Sep 30, 2026 | Florida Pest Control, Pest Control

By Jason Womack, Quality Assurance Inspector · Last updated: September 2026

Quick answer: Yes, cockroaches can bite humans, but it happens rarely. Bites only occur during severe infestations where food is scarce, and they typically target fingernails, eyelashes, or calloused skin while a person sleeps. If you are seeing bite marks, it usually means the roach population in your home has grown large enough to require professional attention.

Roaches scattering when the kitchen light flips on is unsettling enough. The question that follows for a lot of South Florida homeowners is whether these insects can actually bite. It is a fair question in a region where warm, humid weather keeps cockroach populations active nearly year-round, from Naples and Fort Myers to Miami, Miami Gardens, and Pompano Beach.

This guide covers when cockroach bites happen, what they look like, how to tell them apart from bed bug, flea, mosquito, and ant bites, which South Florida species are actually capable of biting, and what to do if you find evidence that they have.

Why Cockroaches Bite (and Why It Is So Rare)

Cockroaches are scavengers, not predators. Their natural diet is food scraps, grease, cardboard, and organic debris, so they have little reason to seek out human skin under normal circumstances. Biting becomes a possibility only when an infestation reaches a scale where competition for food is intense and the usual food sources have been depleted.

In those conditions, roaches may feed on:

Dead skin cells or calloused patches, such as on the feet or hands
Fingernails
Eyelashes
Minor wounds or dried saliva around the mouth

Because these situations require both a large population and limited food, a cockroach bite is far more likely to signal a serious infestation than an isolated pest encounter.

What a Cockroach Bite Looks Like

A cockroach bite typically appears as a small, red, slightly raised bump, similar in appearance to a mosquito bite. It may itch or become mildly inflamed, and in some cases, minor swelling can develop around the site. Because the reaction is so generic, a cockroach bite is difficult to confirm by appearance alone. Without other evidence of an infestation, such as droppings, shed skins, or an unpleasant odor, most bite marks blamed on cockroaches turn out to have a different cause.

Cockroach Bite vs Bed Bug, Flea, Mosquito, and Ant Bites

Because cockroach bites are rare and non-distinct, a different pest is far more likely. The table below shows how these bites compare.

Feature	Cockroach	Bed Bug	Flea	Mosquito	Ant
Appearance	Raised red bump, sometimes with mild swelling	Small red welt, often with a darker center	Tiny red dot with a red halo	Puffy, round, pale-to-pink welt	Red bump, may blister or form a white pustule
Pattern	Isolated or a few scattered bites	Lines or clusters, often in a row	Clusters of several bites	Random, scattered	Single or grouped where ants contacted skin
Body location	Hands, face, near the mouth	Areas exposed while sleeping, like arms and shoulders	Lower legs, ankles, feet	Any exposed skin	Feet, ankles, or wherever contact happened
Timing	Overnight, while still	Overnight, while sleeping	Daytime or night, often after floor contact	Dawn, dusk, and evening	Immediately, on contact

Comparison chart showing how cockroach bites differ from bed bug, flea and mosquito bites

If your bites appear in tidy rows or clusters along your arms or neck, a South Florida bed bug issue is a far more common explanation than cockroaches. If they sit low on the ankles and feet, fleas are worth ruling out. A pest control professional can inspect the pattern and location of the bites to help identify the source.

Which Cockroaches in South Florida Actually Bite

Not every species carries the same biting risk, and infestation size matters more than species alone. Three types turn up most often in South Florida homes:

American cockroach. The largest common household species in the region, reddish-brown and often two inches long. It turns up in drains, sewers, and moist areas like garages and bathrooms, and its size and strong mouthparts put it among the species realistically capable of biting a person.
German cockroach. Smaller and faster-reproducing, this species is the most likely to reach the high population densities associated with biting incidents, since it thrives indoors near kitchens and food sources.
Australian cockroach. Similar in appearance to the American cockroach but slightly smaller, this species is common in South Florida’s warm, humid climate and tends to move between outdoor vegetation and homes.

American cockroach, commonly called a palmetto bug in Florida, on a pool deck

About the palmetto bug: in Florida, “palmetto bug” is a common nickname rather than a separate species. It usually refers to the American cockroach, and sometimes the Florida woods cockroach or Australian cockroach. So when a neighbor mentions a palmetto bug, they are almost always describing a large cockroach. Yes, a palmetto bug can bite, but like other roaches, it only does so when a population has grown large and food is scarce.

Whatever the species, biting is tied to infestation severity rather than being a trait of any one type of roach.

Are Cockroach Bites Dangerous?

Cockroach bites are not venomous, so the main concern is not the bite itself but what the insect leaves behind and the infestation surrounding it. Because roaches travel through drains, garbage, and decaying matter, a bite can introduce bacteria to broken skin and lead to irritation or infection if it is not kept clean.

The risks actually worth watching for are:

Contamination and infection at the bite site if it is scratched or left unclean
Allergic reactions, such as redness, swelling, or itching beyond the bite
Asthma and respiratory irritation from ongoing exposure to roach droppings and shed skins

Cockroach droppings, saliva, and shed skins contain proteins that act as allergens and can trigger asthma attacks, particularly in children and older adults. According to UF IFAS Extension, cockroaches in Florida homes are both a contamination concern and a documented source of household allergens. The bite is rarely the real risk. The infestation that made it possible is.

How to Treat a Cockroach Bite

Most cockroach bites heal on their own with simple care:

Clean the area with soap and warm water to remove any bacteria left behind.
Apply an antiseptic to help prevent infection at the broken skin.
Use a cold compress for several minutes to ease swelling and discomfort.
Take an antihistamine or apply anti-itch cream if the area itches, which also helps you avoid scratching.
Monitor for infection over the next few days, watching for spreading redness, warmth, pus, or increasing pain.
Seek medical care if the bite worsens, does not improve, or if you notice signs of a stronger allergic reaction.

As a general threshold, contact a healthcare provider if the site looks infected, the reaction spreads well beyond the bite, or you feel unwell.

A Bite Means You Have a Bigger Problem

If a bite mark on your skin is genuinely from a cockroach, it is a signal that the population inside your home has grown large enough to outpace available food sources. By the time a home reaches that point, there is usually heavy activity across multiple rooms, not just the kitchen.

Cockroach droppings and an egg case inside a kitchen cabinet, signs of an established infestation

A home at that level has more going on than a single roach. You may find droppings that resemble ground coffee or black pepper, a musty odor, egg cases tucked into cracks, and roaches active during the day, which points to crowding. Those are the signs of an established colony working through walls, cabinets, and plumbing chases.

That is why a bite calls for an inspection rather than a quick spray. Treating what you can see rarely reaches the harborage points where roaches breed, and a proper assessment finds those hidden areas and addresses the source.

Distinguishing a cockroach bite from other pests also matters for treatment.

“When a customer tells me something is biting them at night, the first thing I look for is activity around the sleeping areas. Signs of an infestation usually give us a good indication of what may be biting them. Fleas, bed bugs, and mosquitoes are the most common culprits, while cockroach bites are extremely rare,”

says Mike Vilchez, Quality Assurance Technical Field Trainer for South Florida.

Cockroach Pressure Across South Florida

Cockroach activity varies by region, but South Florida’s warm, humid climate keeps populations active throughout the year in a way that colder markets do not experience.

“The difference in South Florida is that roaches never really get a break. In markets with a true winter, colder temperatures knock populations back each year. Here, they can breed year-round, so control is about staying ahead of them season after season, not just treating once,”

explains Mike Vilchez, Quality Assurance Technical Field Trainer for South Florida.

That year-round pressure shows up across the region, in Naples, Fort Myers, Miami, Miami Gardens, and Pompano Beach. Multi-family buildings and condos share walls and plumbing chases that let German cockroaches travel between units, while irrigation, mulch beds and mature landscaping keep American cockroaches harboring right outside the walls. Homeowners in Naples dealing with recurring infestations may find more detail on cockroach pressure in Naples specifically, including local prevention steps tailored to that market.

How to Get Rid of Cockroaches for Good

Sanitation and exclusion are what keep populations from reaching the levels associated with bites and health risks:

Sanitation first. Clean up crumbs and spills promptly, wipe grease from counters and stovetops, avoid leaving dishes out overnight, and store food, including pet food, in sealed containers.
Correct moisture. Repair leaking pipes and fixtures, address condensation, and reduce standing water around the home. Moisture is often the single biggest draw in South Florida.
Reduce harborage. Seal cracks around baseboards, pipes, and window frames, pull mulch beds back from the foundation, and cut back dense landscaping that touches the structure.
Reduce clutter, particularly cardboard and paper, which cockroaches use for shelter.

Method matters as much as effort. Gel baits placed in cracks and near harborage points are usually more effective indoors than surface sprays, because roaches carry the bait back to where they nest. Broad spraying can scatter a population and miss the source, which is why placement and technique separate a temporary drop in activity from real control.

For infestations that have progressed beyond basic prevention, cockroach control in South Florida from a licensed provider is a more reliable path than store-bought treatments alone. A professional program combines a full inspection, targeted baiting, moisture and harborage guidance, and follow-up monitoring, built for a climate where roaches stay active every month of the year.

Frequently Asked Questions

Do cockroaches bite humans?

Yes, cockroaches can bite humans, but it is uncommon. A bite usually happens only when a population has grown large and run short of its usual food, prompting roaches to feed on skin cells and food residue on people. A bite signals an established infestation worth inspecting.

Do cockroaches bite you in your sleep?

They can, though it is rare. Bites tend to happen overnight because hands and faces are still and easy to reach, and because roaches are most active in the dark. If you are waking up with unexplained bites, it is worth ruling out both cockroaches and bed bugs with a professional inspection.

What does a cockroach bite look like?

A cockroach bite usually appears as a small, raised red bump, sometimes with mild swelling, and it may itch. Bites often show up on the hands or face, alone or in small scattered groups rather than in the tidy rows common with bed bugs.

Are cockroach bites dangerous?

Cockroach bites are not venomous, so the main risks are contamination at the bite site and the allergens roaches spread. Keep the area clean, watch for signs of infection, and see a doctor if it worsens or spreads.

Do palmetto bugs bite?

Yes, a palmetto bug can bite, since “palmetto bug” is simply a Florida nickname for large cockroaches like the American cockroach. Like other roaches, it only bites on rare occasions, typically when a population has grown large and food is scarce.

How do I know if it was a cockroach or a bed bug?

Pattern and location are the best clues. Cockroach bites are usually scattered near the hands and face, while bed bug bites tend to line up in rows or clusters on skin exposed during sleep. When the signs are unclear, an inspection can confirm the source.

Concerned About Cockroach Activity in Your South Florida Home?

If you have noticed signs of a growing cockroach population, or you are not sure what is behind a bite mark on your skin, a professional inspection can identify the cause and the right next step.

Common Winter Pests That Stay Active in Savannah Homes

Dec 9, 2025 | Pest Control

Winter in Savannah brings cooler temperatures and a break from the summer heat, but not from pest activity. Because the area’s winters are mild, many pests remain active — often moving indoors in search of warmth, food, and shelter. Rodents, cockroaches, and spiders are among the most common intruders this time of year. Understanding which common winter pests stay active and how to keep them out is the first step to protecting your home all season long.

Why Pests Seek Shelter in Winter

Even a subtle drop in temperature can signal a significant change for pests. As their natural outdoor habitats become less hospitable, your home offers an ideal alternative with stable temperatures, moisture, and a consistent supply of food. This instinctive drive for survival is what leads to an increase in indoor pest sightings during the winter months. These pests can enter through the smallest of openings, turning your home into their winter retreat.

Rodents: Mice and Rats

House mice and roof rats are two of the most common pests to invade Savannah homes in winter. They are intelligent and resourceful, capable of squeezing through tiny cracks and holes to gain entry.

Behavior: Once inside, rodents establish nests in dark, secluded areas like attics, basements, wall voids, and behind large appliances. They are nocturnal, so you may hear scratching or scurrying sounds at night before you ever see a mouse or rat.
Risks: Rodents pose a considerable risk to property and well-being. They must constantly gnaw to keep their incisors short, leading them to chew through electrical wiring, drywall, and plastic pipes, which can create fire hazards and cause leaks. They also contaminate food and surfaces with their droppings and urine.

Cockroaches

Cockroaches are a year-round problem in Georgia, but their indoor presence can become more noticeable in winter. Species like the American cockroach and the German cockroach are experts at finding their way inside.

Behavior: Cockroaches are drawn to moisture and food. They often hide in kitchens, bathrooms, laundry rooms, and basements. They thrive in cluttered areas and can reproduce quickly, allowing a small problem to become a major infestation in a short amount of time.
Risks: Cockroaches can spread germs and bacteria across your home. Their shed skins, droppings, and saliva contain proteins that are known to trigger allergies and asthma symptoms, especially in children and sensitive individuals.

Spiders

Spiders are not typically winter pests, but they often follow their food source—other insects—indoors. If you see an increase in spiders, it could be a sign of another underlying pest issue.

Behavior: Spiders prefer quiet, undisturbed areas to build their webs, such as corners, closets, basements, and attics. While most common house spiders are not aggressive, their presence and webs can be a nuisance.
Risks: The primary concern with spiders is their webs and the unsettling feeling of sharing your home with them. Their presence often indicates that other pests are available as a food source within your home.

Effective Winter Pest Prevention Strategies

A proactive approach is the best way to maintain a pest-free home. Focusing on exclusion and sanitation can make your property far less appealing to these unwanted winter guests.

Seal Entry Points

Carefully inspect your home’s exterior for any gaps or openings that pests could use to get inside.

Fill cracks in the foundation and around windows with caulk.
Use steel wool to seal holes around pipes and utility lines, as rodents cannot chew through it.
Install weather stripping on doors and windows to create a tight seal.

Eliminate Attractants

Remove the food, water, and shelter that pests are searching for.

Store all food, including pet food, in airtight containers.
Clean up crumbs and spills immediately and avoid leaving dirty dishes in the sink.
Fix leaky faucets and pipes to reduce moisture.
Keep your home, especially storage areas like basements and attics, clean and clutter-free.

When Professional Help Is Needed

While these prevention methods are effective, an established pest population can be difficult to manage on your own. If you see signs of infestation, such as droppings, gnaw marks, or the pests themselves, it is time to consult a pest control professional to ensure your Savannah home remains a comfortable, pest-free space this winter.

Why Licensed Pest Control Is a Must for Your Home

Nov 28, 2025 | Pest Control

When you discover pests in your home or business, your first instinct is to get the problem handled as quickly as possible. In that rush, you might be tempted to hire the first person who offers a solution, especially if they show up at your door with a convincing sales pitch. However, not all pest control providers are created equal. Choosing an unlicensed individual over a certified professional can lead to significant risks, ineffective treatments, and even greater costs down the road.

Hiring a licensed pest control professional is more than a preference—it’s a crucial step in protecting your property, your family, and your peace of mind. Licensed experts bring a level of training, accountability, and knowledge that unlicensed operators simply cannot match. This post will explore why working with a licensed professional matters and highlight the potential dangers of cutting corners.

The Risks of Hiring Unlicensed Pest Control

Recently, the Georgia Department of Agriculture (GDA) issued a warning to residents about a spike in unlicensed individuals selling pest control services door-to-door. This official alert underscores a persistent problem that puts consumers at risk. Unlicensed operators may seem like a bargain, but the potential consequences are serious.

1. Improper Use of Pest Control Products

One of the greatest dangers of hiring an unlicensed operator is the misuse of pest control products. Licensed technicians receive extensive training and understand how to:

Select solutions appropriate for specific pests and settings
Apply these solutions in ways that protect your home and support environmental health
Handle, store, and dispose of products responsibly to prevent harm

Without this expertise, an unlicensed individual might use the wrong product or apply it incorrectly, resulting in ineffective control and unnecessary risk to your property, your family, and the local ecosystem. This not only fails to solve the pest issue but can also introduce new problems.

2. Lack of Knowledge and Expertise

Effective pest control is a science. It requires a deep understanding of pest biology, behavior, and harborage areas. A licensed professional doesn’t just spray chemicals; they conduct a thorough inspection to identify the root cause of the infestation. They can distinguish between different types of pests and know the most effective, targeted strategies to eliminate them.

An untrained person, on the other hand, is likely to take a one-size-fits-all approach. This often leads to temporary relief at best, while the core problem remains unsolved. The pests will almost certainly return, forcing you to spend more time and money on a problem that could have been resolved correctly the first time.

3. No Accountability or Insurance

What happens if an unlicensed operator damages your property or fails to get rid of the pests? In most cases, you have little to no recourse. Reputable, licensed pest control companies are required to carry liability insurance. This protects you in the event of accidental damage to your home during treatment.

Furthermore, licensed companies stand behind their work. If a pest issue persists after a service, a professional team will return to make it right. With an unlicensed individual, there are no guarantees. They may be difficult to contact after receiving payment, leaving you with a lingering pest problem and a lighter wallet.

4. Legal and Compliance Issues

According to the GDA, anyone soliciting or performing pest control services in Georgia must have a valid license. Hiring someone without the proper credentials means you are dealing with an individual operating outside the law. These operators are not held to any state or federal standards, and violations can result in significant fines for the provider. For you, the customer, it means there is no regulatory body overseeing the quality or wellbeing of the work being done.

The Benefits of Working with a Licensed Professional

Choosing a licensed pest control company is an investment in quality and long-term results. Highly trained inspection specialists are equipped to catch and resolve customer concerns with precision.

Expertise and Continuous Training

Licensed technicians are career professionals who receive ongoing education on the latest pest control technologies, protocols, and environmentally responsible practices. This commitment to expertise ensures any pest challenge can be handled effectively, from common ants and cockroaches to more complex issues like termites and rodent infestations. Detailed site evaluations help pinpoint risks and provide actionable recommendations for a pest-free environment.

Environmentally Responsible Approach

Licensed providers focus on minimizing chemical use by combining targeted treatments with non-chemical methods such as exclusion, sanitation improvements, and monitoring. This integrated approach is effective while also being environmentally responsible.

Guaranteed Results and Customer Care

Partnering with a licensed company provides access to responsive customer care and a team that is accountable for results. Clients receive regularly scheduled service designed to prevent future infestations, and any issues that arise between visits are promptly addressed. The goal is to provide effective solutions and the confidence that comes with knowing a home is protected by trained experts.

Fall Invaders: Managing Stink Bugs and Asian Lady Beetles in Hermitage Homes

Nov 14, 2025 | Pest Control

As autumn arrives in Hermitage, Tennessee, the cooling temperatures signal a change in pest behavior. Homeowners may notice an increase in certain uninvited guests, specifically stink bugs and multicolored Asian lady beetles. These pests congregate on the sunny sides of buildings and seek entry to overwinter. Understanding their habits is the first step toward effective management.

This guide provides information on why these pests invade homes during the fall and offers practical, preventative strategies to protect your property. A proactive approach is key to ensuring your home remains a comfortable, pest-free environment throughout the season.

Understanding Fall-Invading Pests

Both stink bugs and Asian lady beetles are considered nuisance pests. While they do not typically cause structural damage or pose significant health risks, their presence in large numbers can be a considerable annoyance.

Brown Marmorated Stink Bugs

Native to Asia, the brown marmorated stink bug is now a common sight across the United States. These shield-shaped insects are about a half inch long and mottled brown. As their name suggests, they release a foul odor when disturbed or crushed, which is their primary defense mechanism. During fall, they seek warm, sheltered places to hibernate, making homes an ideal target.

Multicolored Asian Lady Beetles

Often mistaken for native ladybugs, Asian lady beetles can be identified by their variable coloration, ranging from tan to reddish-orange, and a distinctive ‘M’-shaped marking behind their head. Like stink bugs, they gather in large numbers on sunny, exterior walls in the fall. They seek out small cracks and crevices to enter homes, where they will remain dormant until spring.

Why These Pests Invade Hermitage, Tennessee Homes

The primary driver for these fall invasions is survival. As temperatures drop and daylight hours shorten, stink bugs and Asian lady beetles enter a hibernation-like state called diapause. To survive the winter, they must find a protected location that shields them from the elements.

Your home offers the perfect refuge. It provides warmth, shelter, and protection from predators. These pests are drawn to the heat radiating from sun-exposed siding and will exploit any available opening to get inside, often congregating in attics, wall voids, and behind baseboards.

Proven Strategies for Pest Prevention

The most effective way to manage fall invaders is to prevent them from entering your home in the first place. A few key preventative measures can make a significant difference.

Seal Potential Entry Points

A thorough inspection of your home’s exterior is the most critical step. Denying pests entry is your best line of defense.

Inspect and Seal: Examine your foundation, siding, and areas around windows, doors, and utility pipes for any cracks or gaps. Use a high-quality silicone caulk to seal these vulnerabilities.
Repair Screens: Ensure all window and door screens are in good condition and free of tears or holes.
Secure Vents: Install fine-mesh screening over attic vents, exhaust fans, and chimneys to block potential access points.

Reduce Exterior Attractants

Making the exterior of your home less appealing can discourage pests from gathering.

Exterior Lighting: Consider using yellow “bug lights” for exterior fixtures, as they are less attractive to insects.
Manage Landscaping: Trim back vegetation and tree branches that touch your house, as pests can use these as bridges to gain access.

Proper Removal of Indoor Pests

If you find stink bugs or lady beetles inside, avoid crushing them. Instead, use a vacuum cleaner with a hose attachment to remove them. Once collected, you can dispose of the vacuum bag to prevent odors from lingering.

By implementing these exclusion and prevention techniques, you can significantly reduce the likelihood of a fall pest invasion. Protecting your home requires a proactive and consistent approach.

If you are experiencing a persistent issue with stink bugs, Asian lady beetles, or other pests, professional intervention may be necessary. Contact a certified pest control expert for a comprehensive property inspection and a customized management plan to address your specific needs.

Oct 30, 2025 | Pest Control

As winter arrives in Laurens, SC, cooler temperatures often drive pests indoors in search of warmth, food, and shelter. Your home becomes a cozy refuge, making it a prime target for winter infestations. Knowing which pests are most likely to move inside is the first step toward protecting your property.

The Most Common Winter Pests

Rodents (Rats and Mice)

Rodents are among the most persistent winter pests. With outdoor food scarce and temperatures dropping, mice and rats seek warmth and reliable food indoors. They can squeeze through tiny cracks in foundations, siding, and rooflines.

(Risks Posed by Rodents)

Inside, rodents can gnaw on wiring, creating a fire hazard, and damage insulation or drywall for nesting. They also contaminate surfaces with droppings and urine, carrying diseases and bacteria that can affect your family’s health.
