Spiders in Georgia — 10 Common Species & What You Should Know
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.

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.

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.
