The centipede most likely showing up in your Georgia bathroom is the house centipede, the only Georgia species that breeds indoors. UGA Extension is direct about what its presence signals: house centipedes establish themselves where dampness occurs, and that moisture usually points to a structural or functional problem worth finding and fixing.
Key Takeaways
- The house centipede is yellowish-gray with three dark lengthwise stripes and 15 pairs of legs, the last two noticeably longer than the rest. It’s the only Georgia species that lives and reproduces indoors.
- Stone and bark centipedes live outdoors under rocks, leaf litter, and debris. They occasionally wander inside but don’t reproduce there and die within days.
- Centipede bites are uncommon and cause mild, localized pain similar to a bee sting. Neither the house centipede nor Georgia’s outdoor species are medically significant.
How to Identify Centipedes Found in Georgia Homes
Georgia’s two centipedes, side by side
One breeds indoors and points to a moisture problem. The other just wandered in and won’t last the week.
House Centipede
Stone & Bark Centipede
Georgia’s two most commonly encountered centipede groups look different enough to tell apart with a close look, and the distinction matters practically because one species reproduces indoors and the other doesn’t.
| Feature | House Centipede | Stone / Bark Centipede |
|---|---|---|
| Color | Yellowish-gray with three dark lengthwise stripes | Varies widely; black, brown, tan, red, or orange; most Georgia species are darker |
| Body shape | Long, slender; body segments visible | Flattened from top to bottom |
| Legs | 15 pairs; last pair noticeably longer than the others, often mistaken for antennae | One pair per body segment; variable number depending on species |
| Antennae | Very long; used to sense vibration and movement | Long; proportionately shorter than house centipede |
| Size | About 1 to 1.5 inches in body length, though the long legs and antennae make it look considerably larger | Varies widely by species; from under an inch to several inches |
| Where found | Indoors in damp areas: bathrooms, basements, crawl spaces | Outdoors under rocks, leaf litter, logs, debris; rarely far from moisture |
| Reproduces indoors | Yes, the only Georgia centipede that does | No |
The house centipede’s trailing last pair of legs often leads people to misidentify the back end as a second head, which combined with its speed makes it one of the more alarming-looking insects found in Georgia homes. Despite that impression, UGA Extension is clear that it’s harmless to people and pets.
Why Centipedes Show Up Inside a Georgia Home
Centipedes don’t move indoors by choice in any meaningful sense. They follow moisture and food, and a home that provides both will keep seeing them regardless of how many are removed.
Moisture Is the Root Cause
UGA Extension Bulletin B1088 is specific about this: the house centipede is often seen in and around homes where dampness occurs, and excessive moisture indicates a structural or functional problem in a home. Leaking pipes, condensation, poor ventilation in a basement or crawl space, and water intrusion around a foundation all create the conditions house centipedes need to survive and reproduce. Finding them regularly in a bathroom or basement is as much a plumbing or ventilation signal as it is a pest sighting.
Insect Prey Follows the Same Moisture
The house centipede feeds on flies, spiders, cockroaches, silverfish, and similar household insects. Those insects are often drawn to the same damp conditions the centipede is, so a house with consistent moisture problems tends to accumulate both the insects and the centipede that hunts them. This is why addressing the moisture rather than the centipede alone is the more effective fix.
Outdoor Species Wander in Through Gaps
Stone and bark centipedes get inside through gaps under doors, around pipes, or through foundation cracks rather than seeking out the interior. They don’t breed indoors and die within a few days once inside, so finding one or two near a door is rarely a sign of an established population.
Where Centipedes Hide in and Around a Georgia Home
Centipedes concentrate in specific locations on both sides of the foundation, not evenly across a property. The indoor spots are almost always damp and undisturbed, while the outdoor ones tend to be shaded debris zones right against the exterior wall, which is exactly where the two sides of the problem connect.
Damp Indoor Areas
House centipedes are most active at night and spend daylight hours hidden in damp, undisturbed spots. Bathrooms near drains and under sinks, basements, crawl spaces, and laundry areas are the most common indoor locations. Any spot with consistent moisture and low foot traffic is worth checking if centipedes have been seen regularly.
Outdoor Harborage Near the Foundation
Stone and bark centipedes live under rocks, logs, leaf piles, mulch, and other debris that holds moisture. Harborage close to the foundation, especially on the shaded, north-facing sides of a house, creates a reservoir of outdoor centipedes that occasionally find their way inside through foundation gaps.
What to Do About Centipedes in Your Georgia Home
Reduce Moisture First
For house centipedes, addressing the moisture source is more effective than removing individual centipedes. Repairing leaking pipes, improving basement or crawl space ventilation, running a dehumidifier in persistently damp areas, and ensuring gutters and downspouts direct water away from the foundation all reduce the conditions the species needs to establish itself indoors.
Remove Outdoor Harborage and Seal Entry Points
Removing leaf litter, woodpiles, and other debris from the immediate area around the foundation reduces the outdoor centipede population and removes the staging ground for incidental indoor sightings. Sealing cracks around the foundation, doors, windows, and utility penetrations closes the gaps both species use to get inside.
When to Call a Pest Control Professional
One centipede in a bathroom isn’t worth treating on its own. It’s worth calling in help when house centipedes are appearing regularly in the same areas despite basic moisture control, or when you want a professional to identify the moisture source the centipedes are pointing to rather than just dealing with what’s visible on the floor.
Smart Solutions Pest Control’s pest control service in the Atlanta area starts with an inspection to identify which species are present and confirm where moisture is concentrating indoors, then targets treatment to those specific conditions rather than applying a general perimeter spray.

Frequently Asked Questions
Are centipedes in Georgia dangerous?
No. Georgia’s centipede species are not considered medically significant. A bite is possible if a centipede is handled or cornered and typically causes mild, localized pain and redness similar to a bee sting. Most Georgia centipedes, including the house centipede, rarely bite people at all.
What does a house centipede look like?
House centipedes are yellowish-gray with three dark stripes running lengthwise down the back and have 15 pairs of legs, with the last pair distinctly longer than the rest. They look considerably larger than their 1 to 1.5 inch body length because of the long legs and antennae, and they move in a distinctive rippling pattern rather than the side-to-side motion of outdoor centipede species.
Why do I keep finding centipedes in my bathroom?
Bathrooms provide exactly the moisture and shelter house centipedes need, and they also tend to contain the insects the house centipede feeds on. Regular sightings near drains or under the sink point to a consistent moisture source rather than random wandering.
Do centipedes cause damage to a home?
No. Centipedes don’t damage wood, fabric, food, or any structural component of a home. The concern when house centipedes are present isn’t what they’re doing directly; it’s what their presence indicates, a moisture condition worth finding and fixing before it creates other problems.
