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.

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.

Georgia’s hot, humid climate is excellent for almost everything, including the dozens of spider species that live here. At Northwest, we run spider control calls year-round across our Georgia and Alabama service area, but they spike sharply from April through October as outdoor temperatures rise and spider populations boom. The good news for homeowners: the vast majority of the spiders in Georgia are harmless. Only a handful are medically significant, and even those are uncommon to encounter indoors.
Here are the 10 spiders you’re most likely to see around a Southeast home, how to identify each, which ones warrant caution, and what to do when you find one.
Most spiders in Georgia are outdoor garden spiders that quietly handle the local insect population.
Why Understanding Spiders in Georgia Matters
Spiders play an important role in controlling insect populations. The yellow garden spider you find in your shrubs eats hundreds of mosquitoes, gnats, and flies over a summer. The cellar spider in your basement is quietly catching the small flies you don’t want around. Most spiders in Georgia are doing free pest control on your behalf.
That said, two facts make spider identification matter for homeowners:
- A small number of species are medically significant. Three to four species in the Southeast can deliver bites that require medical attention. Identifying them quickly matters.
- Most “scary-looking” spiders are completely harmless. Wolf spiders, orb weavers, jumping spiders, and the famous Joro spider all look intimidating but pose no real threat. Knowing which is which prevents unnecessary panic and unnecessary pesticide use.
Georgia’s climate produces spider activity peaks in spring (April through May), late summer (August), and early fall (September through October). Most encounters are outdoors.
10 Common Spiders in Georgia
Two species require caution. The other eight are quiet helpers around Southeast homes.
1. Southern Black Widow (Latrodectus mactans)
- Status: Venomous. Bite requires medical attention.
- Appearance: Glossy black body with the distinctive red hourglass marking on the underside of the abdomen. Adult females are about 1/2 inch (legs spread to 1.5 inches). Males are much smaller and not medically significant.
- Habitat: Dark, undisturbed areas. Sheds, garages, crawl spaces, woodpiles, basement corners, under outdoor furniture. Common in rural and suburban Georgia.
- Action: If you find one in or around your home, call professional pest control. Do not attempt to capture or kill without protection. Bites cause severe muscle pain, abdominal cramping, and sometimes systemic reactions.
2. Brown Widow (Latrodectus geometricus)
- Status: Venomous, but less potent than the black widow
- Appearance: Tan to brown body with darker mottled markings. Distinctive orange hourglass marking on the underside (similar shape to black widow’s, but orange instead of red). Egg sacs have a spiky, golf-ball-like appearance.
- Habitat: Outdoor structures, under patio furniture, in eaves, around mailboxes, under flower pots. More common in suburban and urban Georgia than rural areas.
- Action: Bites are usually less severe than black widow bites but still warrant medical attention. Treat with the same caution and call professional control.
3. Wolf Spider
- Status: Non-venomous to humans (bite is mild, comparable to a bee sting at worst)
- Appearance: Large, hairy, brown to gray with darker markings. Body can be 1 to 2 inches with a 3-inch leg span. Eight eyes arranged in three rows.
- Habitat: Ground dwellers. They don’t build webs. They hunt. Often enter homes accidentally chasing prey. Common in basements, garages, and ground-floor rooms.
- Action: Harmless but startling. Trap with a cup and release outside.
4. Cellar Spider / Daddy Long Legs (Pholcidae)
- Status: Harmless
- Appearance: Small slender body (under 1/2 inch) with extremely long thin legs. Light tan to gray.
- Habitat: Indoor ceiling corners, basements, garages, crawl spaces. Builds messy tangled webs.
- Action: Leave them alone if you can. They eat mosquitoes, fruit flies, and other indoor pests. For a deeper dive, see our cellar spider vs daddy long legs guide.
5. Orb Weaver Spiders
- Status: Venomous to prey, harmless to humans
- Appearance: Vary widely in color and size. Many species have rounded abdomens with bright patterns (yellow, black, brown, orange). Common Georgia species include the yellow garden spider, garden orb weaver, and the spinybacked orb weaver.
- Habitat: Outdoor gardens, shrubs, between fence posts, under eaves. Builds the classic large circular web.
- Action: Leave them alone. They’re significant outdoor pest controllers. For more on whether their venom matters, see our orb weaver spider guide.
6. Jumping Spiders
- Status: Harmless
- Appearance: Small (1/4 to 3/4 inch), compact, fuzzy body. Often striking patterns and large forward-facing eyes that give them an almost cute appearance. Move in distinct jumps rather than walking smoothly.
- Habitat: Active hunters that don’t build webs. Common indoors and outdoors. Often spotted on walls, window frames, and porches during the day.
- Action: Among the most charming spiders you’ll meet. Harmless and useful.
7. Yellow Sac Spider
- Status: Mildly venomous. Bites possible but rarely serious.
- Appearance: Pale yellow to cream-colored, small (1/4 inch body). Slim legs.
- Habitat: Corners of ceilings, window sills, under loose bark, in folded leaves outdoors. Builds small silken retreats rather than full webs.
- Action: One of the few spiders that may bite without obvious provocation. Bites cause localized pain, redness, and itching that resolves in a few days. Vacuum sightings; call professionals for recurring activity.
8. Crab Spiders
- Status: Non-venomous to humans
- Appearance: Crab-like stance (front legs held out to the sides). Often brightly colored to match flowers (white, yellow, pink). Small body, usually under 1/2 inch.
- Habitat: Gardens, flowers, and shrubs. Ambush predators that wait on blooms to catch pollinators.
- Action: Beneficial outdoors. Leave them alone.
9. Hobo Spider
- Status: Low-risk venom (medical significance has been re-evaluated and downgraded in recent CDC guidance)
- Appearance: Medium-sized brown body with chevron patterns on the abdomen. Long legs. Often confused with wolf spiders.
- Habitat: Basements, dark corners, ground-level spaces. Builds funnel-shaped webs.
- Action: Less common in Georgia than in the Pacific Northwest. Treat as you would a wolf spider: trap and release, or call professionals for recurring activity.
10. Joro Spider (Trichonephila clavata) — The New Arrival
- Status: Harmless to humans and pets
- Appearance: Large, striking. Females have bright yellow and gray-blue striped legs with a yellow abdomen marked with grayish-blue lines and red markings underneath. Leg span up to 4 inches.
- Habitat: Introduced from East Asia, first confirmed in Georgia in 2014. Now established statewide. Builds huge multi-layered golden webs in trees, between buildings, on power lines, across porches.
- Action: Despite their alarming size, Joros are docile and rarely bite. Their fangs are too small to penetrate most human skin. They’re effective predators of other pest insects. Most Georgia residents have started simply leaving them alone.
Venomous vs Harmless Spiders in Georgia
Of the 10 species above, only two are considered medically significant in the Southeast:
- Southern Black Widow: severe neurotoxic venom. Bites require medical attention.
- Brown Widow: less potent than black widow but still warrants medical attention.
Two more deliver bites that can cause discomfort but rarely require medical care:
- Yellow Sac Spider: mild localized reaction.
- Hobo Spider: low-risk; previously thought to be more medically significant.
The other six species are functionally harmless to humans.
What to Do If You’re Bitten
For any suspected spider bite:
- Wash the bite area with soap and warm water.
- Apply a cold compress to reduce swelling.
- Take an over-the-counter pain reliever if needed.
- Watch for severe symptoms: rapidly spreading redness, severe pain, fever, muscle cramping, abdominal pain, difficulty breathing, or any systemic reaction.
- Seek medical attention immediately for any severe symptoms or for any bite from a confirmed widow species.
If possible (and only if safe), capture or photograph the spider for identification. Medical providers handle treatment differently depending on the species.
Spider Identification Tips
Three quick markers help with on-the-spot identification:
- Size and color: Note the body size (excluding legs), overall color, and any distinctive markings (hourglasses, stripes, bright patches).
- Web type: A circular symmetrical web means orb weaver. A messy tangled corner web means cellar spider. A funnel-shaped web means hobo spider or grass spider. No web at all (spider on the floor or wall) often means wolf spider, jumping spider, or one of the widow species (which build messy three-dimensional cobwebs in hidden spots).
- Behavior: Fast movement on the ground suggests wolf spider. Quick jumps suggest jumping spider. Sitting motionless on a flower suggests crab spider. Hanging upside down in a corner web suggests cellar spider.
For authoritative species identification, UGA Extension’s guide to insect and arthropod pests of southeastern neighborhoods covers the common spider species in our region in detail.
How to Prevent Spiders in Your Georgia Home
Spider prevention is straightforward and overlaps with prevention for the insects spiders eat (which is the underlying reason spiders show up in the first place).
Spider prevention is mostly about sealing entry points and reducing the indoor insect population that draws them.
- Sanitation. Remove indoor clutter, especially in basements, attics, garages, and storage spaces. Spiders need stable hiding places.
- Seal entry points. Caulk foundation cracks, install or replace door sweeps and weatherstripping, screen crawl space vents with 1/4-inch hardware cloth, seal gaps around utility line penetrations.
- Yard maintenance. Trim shrubs and tree branches back from the foundation. Remove leaf litter, woodpiles, and debris within 20 feet of the house. Outdoor harborages give spider populations a launching pad.
- Control outdoor lighting. Bright porch lights attract flying insects, which attract spiders. Switch to yellow-tone or warm-LED bulbs to reduce insect attraction.
- Humidity control. Many indoor spiders prefer slightly damp environments. Run dehumidifiers in basements; fix leaks promptly.
For active spider prevention strategies including DIY natural methods, see our natural spider repellent guide.
When to Call Professional Spider Control
Most spider sightings in a Georgia home don’t warrant professional intervention. Call Northwest if:
- You’ve found a confirmed black widow or brown widow on the property.
- You’re seeing recurring spider sightings in living spaces (bedrooms, kitchens, kids’ rooms).
- Population appears large (visible webs in multiple rooms, multiple sightings per week).
- You’re noticing other pest activity at the same time. Spiders are usually a downstream effect of an indoor insect problem.
- Anxiety or safety concerns make a professional inspection worth the peace of mind.
Professional spider control typically combines targeted treatment at active harborage spots, exclusion work to seal entry points, and addressing the underlying insect issue that drew the spiders indoors.

Frequently Asked Questions About Spiders in Georgia
Are spiders in Georgia dangerous?
Most are harmless. Only two species in the Southeast pose real medical risk: the Southern black widow and the brown widow. The yellow sac spider and hobo spider can deliver uncomfortable bites but rarely require medical attention. The other common spiders in Georgia (wolf, cellar, orb weaver, jumping, crab, fishing, Joro) are functionally harmless to humans.
What do spider bites look like?
Symptoms vary by species. Most bites cause mild localized redness, swelling, and itching that resolves in a few days. Black widow bites cause severe muscle pain, abdominal cramping, sweating, and sometimes systemic reactions. Brown recluse bites (uncommon in Georgia) can cause a slow-healing necrotic wound. Any bite with severe pain, rapidly spreading redness, or systemic symptoms warrants medical attention.
How common are venomous spiders in Georgia?
Black widows are present statewide but uncommon to encounter indoors. Brown widows are more common around buildings, especially in coastal and urban areas. Brown recluse spiders are rare in Georgia but not impossible (they’re more common further west). Most homeowners go years between spotting a medically significant spider.
Do spiders help control other pests?
Yes, significantly. Spiders are predators of flies, mosquitoes, gnats, moths, and other household insects. A small spider presence indoors is functionally free pest control. This is one reason most pest professionals (including ours) encourage homeowners to leave individual spiders alone when possible.
What’s the Joro spider and should I worry about it?
The Joro spider (Trichonephila clavata) is an invasive species first confirmed in Georgia in 2014. It’s now established statewide and continues to spread. Despite their alarming size (leg span up to 4 inches) and bright coloring, Joros are docile and rarely bite. Their fangs are typically too small to penetrate human skin. They’re effective predators of pest insects and aren’t considered dangerous.
Most spider problems get solved by sealing entry points and treating the insects they’re feeding on.
Ready for a Professional Spider Inspection?
If you’ve spotted a widow species, you’re seeing recurring indoor sightings, or you just want a professional to identify what’s around your home, Northwest’s team handles the full spider control workflow: species identification, exclusion, targeted treatment, and addressing the underlying insect issues that draw spiders indoors. Most spider problems clear up faster than homeowners expect.
