Spiders are considered year-round pests, but they seem to come out in full force during the summer months. Some common spiders you may encounter this summer include wolf spiders, orb weavers, garden spiders, house spiders, brown recluse spiders, and black widow spiders. While most of these are harmless, brown recluses and black widows can be dangerous to humans with their venomous bites.
The spiders you see in the summer most likely aren’t just now making their way into your home; there’s a good chance they’ve already been hiding out inside for a while. They will commonly emerge in large numbers in the summer for two main reasons:
- It’s mating season for male spiders
- It’s peak season for most of their food sources (mosquitoes, flies, ants)
Seeing a spider here and there inside your home is usually nothing to worry about; they can sneak in through open windows, doors, etc. Seeing them in large numbers, however, can indicate a much bigger problem. Spider infestations can be the result of:
- Weather. Summer weather is ideal for spiders with warm temperatures, adequate shelter, etc. If the weather gets too hot, spiders will seek relief, often inside your home. The same thing applies if the summer is overly dry or overly wet. Your home provides the perfect place to hide out until conditions outdoors improve.
- Food. If food sources outdoors become scarce (due to weather or consistent pest control around your home), spiders may make their way indoors on their search for nutrition. Conversely, if you have an infestation of other household pests that spiders like to eat, they will also come inside to take advantage of the all-you-can-eat buffet.
- Water. Spiders must have water to survive. If outdoor water sources dry up (due to drought, etc.), they will go in search of hydration indoors.
Having a spider infestation in your home can leave you with webs everywhere, the risk of spider bites that can be painful and potentially dangerous, and the possibility of other pest infestations, as well. You can keep spiders out by:
- Eliminating Entry Points. Spiders can access your home through the smallest cracks and crevices. Use weatherstripping around doors and windows and make sure it is kept in good repair. Caulk or seal any gaps, holes, and openings. Use screens on doors and windows and make sure they stay in good repair, as well.
- Eliminating Hiding Places. Spiders prefer dark, undisturbed places to hide out (corners, cabinets, closets, storage containers, piles of paper or cardboard, and cluttered areas). Declutter your home and get rid of any old papers, magazines, newspapers, and boxes. Shake out anything you haven’t used in a while before using it. Vacuum and dust regularly, especially rooms and areas that you don’t use often. Outside, trim overgrown bushes, hedges, and trees. Keep grass mowed short and mow regularly. Get rid of trash and debris in your yard that spiders can use for shelter. Store firewood and lumber away from your home.
- Eliminating Food Sources. Spiders eat other pests. Maintain routine pest control in and around your home with a professional pest control company. Eliminating other pests mean spiders will look for food elsewhere.
If you have a problem with spiders, contact your local pest control company for a thorough inspection and treatment plan.

Although spiders are considered a year-round pest, they become more visible and active in the spring. Overwintering pests like spiders emerge as the weather warms up to lay eggs for the approaching season. Spiders are predators, preying on smaller insects for food. They are usually not a huge threat to humans with only a few venomous species in our area. In fact, they can be quite beneficial to have around your home, working as a form of natural pest control by eating other insects you may have around.
If the thought of sharing your home with spiders creeps you out, don’t fret! Here are some spider prevention tips you can use this spring to help keep these pests out.
- Keep your outdoor lights off at night. Many bugs are attracted to light at night, providing a feast for spiders who are hanging around.
- Keep vegetation trimmed and your lawn mowed. Overgrown bushes, grass, and other debris give spiders the ideal place to hide.
- Don’t stack wood or install mulch to close to the sides of your home. Spiders will not only hide out in these places but will also use them as a bridge to crawl into your house.
- Make sure trees, shrubs, and other landscaping aren’t touching your home. Spiders will also use these to get indoors.
- Clean up food and crumbs immediately, both indoors and outdoors.
- Get rid of stacks of old newspapers, magazines, etc.
- Dust frequently and vacuum weekly.
- Make sure windows and door screens are intact. Spiders will use holes and tears to get inside.
- Get rid of cobwebs both indoors and outdoors. Spiders will use these to store food once they catch their prey.
- Apply diatomaceous earth to your yard. This is a nontoxic option for outdoor pest control that is harmless to humans.
- Consider natural remedies to prevent spiders. Some common methods include the use of mint, citrus, and vinegar.
- Contact a professional. Spiders can be difficult to get rid of on your own. A professional pest control company can help identify the type of spider you are dealing with; where they may be hiding, nesting, or getting inside; and the most effective way to treat them in your home.

The Joro spider, also known as Trichonephila clavata, is a member of the recognizable orb weaver family. These particular spiders are characterized by their large size (up to 3 inches in length with their legs extended) and yellow and blue-black striped backs with red undersides. Joro spiders are known for constructing large, wagon-wheel shaped webs that are a golden color. These webs can be several feet in length.
Joro spiders are native to Asia, particularly Japan, China, Korea, and Taiwan. In 2014, the first instance of the Joro spider in North America was confirmed in North Georgia. Subsequent sightings have been confirmed as far away as Greenville, South Carolina. It is unclear how and when these spiders first arrived here in Georgia but researchers believe they are here to stay. In fact, researchers have confirmed their presence in at least 25 counties in the state.
Joro spiders are not considered harmful to humans or pets. They will bite when provoked but are not considered a threat. Joros are beneficial to have around as they are one of the only species known to eat adult brown marmorated stinkbugs. They also help keep mosquito and other nuisance pest populations in check. Joro spiders do have predators in our area; both birds and wasps will eat them.
The jury is still out on whether or not there will be any long-term ramifications on local ecosystems. One thing all the researchers agree on is that the Joro spider is likely here to stay.

Nothing says “Halloween” like spotting a few cobwebs around the house! While it’s always fun to see cobweb decorations during this time of year, it’s not as fun having to deal with them year-round. Since the temperatures have cooled off, many spiders are looking indoors to inhabit a warmer environment. It’s important to understand common types of spiders in order to provide the best treatment if they’ve infested your home.
Brown Recluse
The brown recluse spider is light to dark brown, with a signature brown violin shape on its backs. If threatened, these spiders will bite, which can be painful and leave an open sore. If bitten, some can experience fever, restlessness, and difficulty sleeping. Brown recluse spiders can be found in debris and woodpiles. If they’ve snuck inside your home, they can often be found under furniture, inside storage items, in baseboards, closets, and crawlspaces.
Wolf Spider
Wolf spiders are dark brown with paler stripes or markings and long, spiny legs. These spiders are large and hairy across their bodies. While these spiders will bite, it’s rare that they do and are not a significant threat to humans. Inside homes, wolf spiders tend to stay near or on the floor, especially along walls and under furniture where they chase their prey instead of capturing them in their webs. If outside, they like to inhabit firewood piles, leaves, yard debris, and stones.
Common House Spider
House spiders can vary in color but are usually yellow to brown with elongated abdomens. Although not a threat to humans, they are a nuisance to have in the home as they can produce and leave behind webs throughout the house. They can often be found in ceiling corners, under furniture, and inside closets, basements, garages, and crawlspaces. If outside, you will commonly find them spinning webs around windows, under eaves, and near light sources that attract food.
By recognizing each spider species and knowing where they most often inhabit, you can utilize the correct preventative measures to eliminate the chance of an infestation. Check out some of these easy do-it-yourself spider prevention tips:
- Keep garages, attics, and basements clutter-free.
- Avoid leaving clothes and shoes on the floor.
- Seal any cracks and crevices around the home.
- Call a professional pest control company. They will perform an inspection and provide you with the correct treatment and prevention plan for any spiders seen throughout your property.

If you’ve walked into a large, intricate spider web stretched across your back porch or between two garden shrubs, you’ve almost certainly met an orb weaver spider. At Northwest, we get calls about these every August and September across Georgia, Alabama, Tennessee, and South Carolina. The conversation almost always starts the same way: I just walked face-first into the biggest web I’ve ever seen. What is this thing and is it venomous?
The honest answer to “are orb weaver spiders venomous?” is: technically yes, practically no. Almost all spiders have venom. It’s how they catch their prey. The real question is whether their venom is dangerous to humans, and for orb weaver spiders the answer is no. They’re among the most beneficial outdoor spiders in the Southeast, and most are completely harmless to people and pets.
The yellow garden spider is the most commonly spotted orb weaver in Southeast yards from late summer through fall.
What Is an Orb Weaver Spider?
Orb weaver spiders belong to the family Araneidae. There are more than 3,000 species worldwide and dozens in the Southeast. They’re named for the iconic circular (“orb”) webs they build, the symmetrical wagon-wheel pattern most people picture when they hear the word “spider web.”
Three things make orb weavers stand out:
- Web architecture. The classic round web with radial spokes and concentric spirals is one of nature’s most efficient insect traps. Orb weavers often rebuild the entire web nightly, eating the old web to recycle the silk proteins.
- Outdoor lifestyle. Almost all orb weavers live outdoors in gardens, yards, wooded areas, and around outdoor structures. Indoor sightings are rare and usually accidental.
- Visible, striking appearance. Many species are large, brightly colored, and impossible to miss when they show up. This is often what generates the homeowner panic that leads to a Google search.
Orb Weaver Spider Identification
Four orb weaver species cover most sightings in Southeast yards. All four are harmless to humans.
Physical Characteristics
Orb weaver spiders vary widely in size and color, but most share these features:
- Rounded, often bulbous abdomens. Females in particular have noticeably round bodies.
- Distinctive patterns or markings. Colors range from bright yellow and black (yellow garden spider) to brown and orange (garden orb weaver) to gray with red accents (Joro spider).
- Long legs relative to body size.
- Significant size difference between males and females. Females are typically 2 to 3 times larger and are the ones you usually notice in webs. Males are smaller, less visible, and often hang at the edge of the female’s web.
Common Orb Weaver Species in Georgia
- Yellow garden spider (Argiope aurantia). The classic large black-and-yellow garden spider with the distinctive zigzag pattern (called a stabilimentum) woven into its web. Common from late August through October.
- Joro spider (Trichonephila clavata). An invasive species first confirmed in Georgia in 2014 and now established statewide. Females have striking yellow, gray-blue, and red markings with banded legs. Builds enormous multi-layered golden webs. Harmless despite their imposing appearance.
- Garden orb weaver (Araneus species). Several brown to gray species that build classic circular webs in shrubs and between fence posts. Usually nocturnal. They build webs at dusk and take them down at dawn.
- Spinybacked orb weaver (Gasteracantha cancriformis). Small (1/4 inch), distinctive white body with red spines giving a crab-like appearance. Common in shrubs and gardens. Easy to identify because nothing else looks like it.
For the broader picture of all common Southeast spider species (including the venomous ones to watch for), see our guide to common spiders in Georgia.
Web Structure
The easiest way to identify an orb weaver is by its web. Orb weaver webs are:
- Circular and symmetrical (the classic Halloween-decoration spider web shape)
- Built between two anchor points, often spanning several feet
- Often built and dismantled daily by nocturnal species
- Strong enough to catch large flying insects (some Joro webs trap small birds, though this is rare)
- Sometimes featuring a zigzag stabilimentum pattern (yellow garden spiders are known for this)
Are Orb Weaver Spiders Venomous?
Yes, technically. But it’s important to understand what “venomous” actually means here.
Almost every spider species on Earth is venomous in the technical sense. Spiders use venom to subdue their prey. What matters for human safety is whether that venom is potent enough to cause harm when delivered to a human via a bite, and whether the spider is even capable of biting through human skin.
For orb weaver spiders, the answers are: not potent, and rarely able to bite humans effectively. Their venom is well-suited to small insects (flies, mosquitoes, moths, beetles) but is not medically significant to humans. Even when an orb weaver does bite a person, the result is typically comparable to a mild bee sting.
Venomous vs Poisonous — Quick Clarification
This is a common point of confusion. The terms aren’t interchangeable:
- Venomous means the animal actively injects toxin (usually via a bite or sting). Spiders are venomous.
- Poisonous means the animal is toxic if you eat or touch it. Spiders are not poisonous.
So orb weaver spiders are venomous (they inject venom into prey) but they’re harmless to humans because the venom isn’t potent enough to cause serious effects.
Orb Weaver Spider Bites
Orb weaver bites are uncommon and rarely cause significant problems. The reasons:
- They’re non-aggressive. Orb weavers retreat when disturbed rather than approach. Their first defense is dropping out of the web and hiding.
- Their fangs are small. Most orb weaver species have chelicerae (mouthparts) that struggle to penetrate human skin.
- They bite only defensively. Bites occur almost exclusively when the spider is trapped against skin (caught under clothing, grabbed accidentally, pressed against a hand reaching into their web).
If you are bitten, expect:
- Mild localized pain similar to a bee sting
- Slight redness and swelling at the bite site
- Possible itching for a day or two
- Full resolution within 2 to 3 days without treatment
More serious reactions are extremely uncommon. As with any bite, seek medical attention if you experience unusual symptoms (severe pain, rapidly spreading redness, fever, difficulty breathing). For most orb weaver bites, washing the area with soap and water and applying a cold compress is sufficient.
Why Orb Weaver Spiders Are Common in Yards & Gardens
Orb weavers thrive where flying insects thrive. In Georgia and Alabama, that means almost every backyard from late spring through early fall. Three factors drive orb weaver populations:
- Flying insect abundance. Mosquitoes, flies, moths, beetles, and other flying insects are the main food source. Yards with lots of flowering plants, gardens, water features, or outdoor lighting tend to have more orb weavers.
- Anchor points for webs. Orb weavers need structures to stretch webs between: shrubs, fence posts, eaves, porch columns, tree branches. Suburban yards with diverse landscaping provide plenty.
- Seasonal life cycle. Most Southeast orb weaver species hatch in spring, grow through summer, and reach peak adult size from late August through October. That’s when their webs become most visible and homeowners notice them.
Late summer and early fall sightings are normal and not a cause for concern. Orb weaver populations die back naturally with the first hard frost.
Orb Weaver Spiders Around Your Home
Most orb weaver spiders stay outdoors. Indoor sightings are uncommon and usually accidental: a spider carried inside on a plant, blown in through an open door, or wandering through a porch in transition between web sites.
If you find an orb weaver indoors:
- Use the cup-and-cardboard method to capture it and release outside in a garden or near a tree.
- Or use a vacuum hose attachment to remove the spider. Quick and gentle.
- Don’t crush them indoors. Orb weavers are highly beneficial outdoor pest controllers, and there’s no reason to kill them.
If you have a web in an inconvenient outdoor location (across a frequently used doorway, on a porch you use daily), gently relocate the spider with a stick or remove the web with a long-handled duster. The spider will rebuild elsewhere within a day.
Safety & Prevention Tips for Orb Weaver Activity
Warm-tone outdoor lighting and trimmed perimeter shrubs reduce where orb weavers build webs.
Most orb weaver “problems” are really just web placement issues. The spider isn’t the problem. The location of its web is. A few changes minimize the inconvenience without harming the population.
- Reduce outdoor lighting attractants. White or bright LED porch lights attract flying insects, which attract orb weavers to build webs nearby. Switch to warm-toned (2700K-3000K) or yellow “bug light” bulbs. Fewer insects mean fewer spiders.
- Remove webs regularly. If a web is in an inconvenient spot (across a door, on a frequently used patio), remove it with a long-handled duster. The spider rebuilds elsewhere. Consistent removal in the same spot trains spiders to relocate.
- Trim back vegetation near the home. A 3-foot clearance between shrubs and exterior walls reduces anchor points for webs near doors and windows.
- Around children and pets. Teach kids to look before reaching into shrubs or web-prone areas. Most orb weaver encounters end with no incident, but a startled spider in a child’s hand can result in a bite. Standard outdoor caution applies.
- Walk paths in the morning. Orb weavers build webs at dusk and often anchor across paths. A quick walk-around in the morning with a stick clears overnight construction before you walk into it.
For broader natural prevention strategies that apply to orb weavers and other Southeast spiders, see our natural spider repellent guide.
When to Call Professional Spider or Pest Control
Orb weavers rarely warrant professional intervention because they’re outdoor spiders that don’t pose health risks. Call Northwest if:
- Orb weavers (or other spiders) are repeatedly setting up indoors in living spaces.
- You’re finding webs in multiple rooms or notable numbers of spiders inside.
- You’ve spotted a venomous species (widow spiders) alongside orb weavers and want a full treatment.
- Outdoor spider populations are large enough to interfere with normal use of porches, patios, or doorways.
- Underlying insect issues are driving spider populations. Addressing the source pest typically reduces spider activity.
Clemson Extension’s guide to large orb-weaver spiders in the Southeast covers the four most commonly seen yellow-and-black orb weavers (yellow garden spider, banded garden spider, golden silk orbweaver, and Joro) and consistently recommends keeping these outdoor spiders in place because of their ecological value. Most professional spider work focuses on entry points and underlying insect populations rather than killing the spiders themselves.

Frequently Asked Questions About Orb Weaver Spiders
What does an orb weaver spider look like?
Most orb weavers have rounded abdomens with noticeable patterns or markings. Colors vary widely: yellow and black (yellow garden spider), brown to orange (garden orb weaver), gray with red accents (Joro spider), or white with red spines (spinybacked orb weaver). Females are typically 2 to 3 times larger than males. The most reliable identifier is the web: a large symmetrical circular pattern stretched between two anchor points.
Do orb weaver spiders build webs at night?
Many do. Several common Georgia orb weaver species are nocturnal builders. They construct webs at dusk and take them down at dawn, eating the old web to recycle the silk proteins. Yellow garden spiders and Joros build during the day and maintain their webs continuously.
What time of year do orb weaver spiders appear?
Orb weavers in Georgia and Alabama are most visible from late August through October. Spiders hatch in spring and grow gradually through summer, reaching maximum adult size in late summer. That’s when their webs become most noticeable. Populations die back naturally with the first hard frost.
Are orb weaver spiders helpful?
Significantly. Orb weavers are some of the most effective natural pest controllers in Southeast yards. A single yellow garden spider can catch hundreds of mosquitoes, gnats, flies, and moths over a season. Most pest professionals (including ours) recommend leaving outdoor orb weavers in place because of their value.
Are orb weaver spider bites dangerous?
No. Orb weaver bites are uncommon (they’re non-aggressive and their fangs struggle to penetrate human skin), and when they do occur, the bite typically causes mild localized pain similar to a bee sting. There are no documented cases of orb weaver bites causing serious medical issues. Wash the area with soap and water and apply a cold compress if needed.
Most spider control focuses on the underlying insect populations, not the spiders themselves.
Leave the Orb Weavers, Call About the Rest
Orb weaver spiders are some of the best outdoor pest controllers your yard has. If you can leave them alone or relocate the occasional inconvenient web, you’re getting free mosquito and gnat control for the price of one slightly creepy backyard tenant. For everything else (widow species, indoor spider populations, recurring activity in living spaces), Northwest’s team can help.
