If you’ve ever spotted a fast-moving, many-legged creature darting across your bathroom floor, you’ve likely met a house centipede. These startling pests are one of the most common calls we get at Better Termite & Pest Control, especially from homeowners in the Alexandria and Northern Virginia areas.
After 57 years in business and over a million homes serviced, I can tell you that centipedes rarely show up without a reason. Understanding what attracts centipedes to your home is the first step toward getting rid of them—and keeping them out for good.
The 7 Things That Attract Centipedes to Your Home
1. Moisture and High Humidity
Moisture is the number one thing that attracts centipedes. These creatures have a unique problem: unlike most insects, they cannot close their breathing pores (called spiracles). This means they lose moisture rapidly and need humid environments to survive.
That’s why you’ll typically find centipedes in:
- Basements and crawl spaces
- Bathrooms (especially near tubs and toilets)
- Kitchens (under sinks)
- Laundry rooms
- Areas with leaky pipes or poor ventilation
One homeowner I spoke with had a problem with millipedes in her basement. After an inspection, we deduced that the cause of the issue was the high moisture content of the soil around her home. The same conditions attract centipedes. When we see centipede activity, we often find the root cause is a moisture problem that’s also attracting their prey insects.
2. Other Pest Insects (Their Food Source)
Here’s something that surprises many homeowners: if you’re seeing lots of centipedes, you probably have another pest problem too.
House centipedes are predators. According to Penn State Extension, they feed on silverfish, firebrats, carpet beetle larvae, cockroaches, spiders, and other small arthropods. A large house centipede population often signals an underlying pest issue.
In my experience working in the DC metro area, German, oriental, and American roaches can be very common—and these are exactly the types of pests that attract centipedes looking for a meal.
According to the National Pest Management Association’s Pestworld Magazine, the first rule of centipede control is thorough inspection to identify what prey insects are drawing them in. House centipedes are “nocturnal predators that prefer smaller arthropods to feed on such as carpet beetle larvae, silverfish, and spiders.”
3. Dark, Undisturbed Hiding Spaces
Centipedes are nocturnal. They prefer dark, quiet areas where they can rest during the day and hunt at night. Common hiding spots include:
- Cardboard boxes stored on concrete floors
- Cluttered storage areas
- Inside cement block walls
- Under furniture that rarely gets moved
- Crawl spaces and unfinished basements
4. Easy Entry Points Around Your Foundation
Centipedes don’t need much space to get inside. Small gaps around pipes, loose siding, open vents, and unsealed windows are all entry points they’ll exploit.
The soil around your home’s foundation is often perfect centipede habitat—it stays cool, moist, and is full of insects. Outdoor species like stone centipedes and soil centipedes thrive in these foundation-edge environments. Once they’re established along your perimeter, slipping inside becomes easy. Homeowners in wooded areas like Fairfax and Burke often see more activity because of the increased moisture and insect populations near trees.
5. Temperature Changes and Weather Extremes
Centipedes move indoors when outdoor conditions become uncomfortable. You’ll see increased activity when:
- Hot, dry weather drives them to seek moisture
- Cold temperatures push them toward heated spaces
- Heavy rains flood their outdoor hiding spots
- Seasonal transitions in spring and fall trigger movement
6. Outdoor Debris Near Your Home
What’s happening outside your home matters just as much as what’s inside. Centipedes thrive in:
- Leaf litter and mulch piled against the foundation
- Firewood stacked near exterior walls
- Landscape timbers and railroad ties
- Dense ground cover plants
- Compost piles
These areas create the moist, protected environments centipedes love—right next to your home.
7. Exterior Lighting That Attracts Insects
While centipedes themselves aren’t attracted to light, their prey insects are. Bright white exterior lights draw moths, flies, and other insects that centipedes hunt. This can create a buffet near your entry doors and windows.
Where Centipedes Hide in Your Home
Understanding where centipedes hide helps you target your prevention efforts. Based on our 57 years of experience, here are the most common locations:
Bathrooms: The combination of moisture, floor drains, and small insects makes bathrooms a centipede favorite.
Basements and Crawl Spaces: These areas often have the highest humidity levels in your home. Concrete block walls and floor drains provide additional entry points.
Kitchens: Under-sink areas with plumbing and potential leaks attract centipedes seeking moisture.
Laundry Rooms: Washing machines create humidity, and floor drains offer entry points.
Garages: Often connected to the house with less sealing, garages provide easy access and plenty of hiding spots.
How to Keep Centipedes Out of Your Home
The key to centipede control is addressing what attracts them in the first place. Here’s my professional approach:
Step 1: Control Moisture
- Use dehumidifiers in basements and crawl spaces
- Fix all leaky pipes and faucets promptly
- Ensure proper ventilation in bathrooms and kitchens
- Grade soil away from your foundation
- Repair any standing water issues
Step 2: Seal Entry Points
- Caulk cracks and gaps in your foundation
- Install screens over floor drains
- Seal around utility pipes and conduits
- Weather-strip doors and windows
- Repair damaged siding and trim
Step 3: Eliminate Hiding Spots
- Remove cardboard boxes from basement floors
- Organize storage areas
- Keep clutter to a minimum
- Move firewood away from your home
- Clear debris from around your foundation
Step 4: Address Prey Insects
Since centipedes follow their food, controlling other pests is essential. If you’re seeing lots of centipedes, consider a general pest control program that addresses the insects they’re hunting.
At Better Termite & Pest Control, our licensed technicians use an integrated approach that addresses both centipedes and their prey. We’re members of the Virginia Pest Management Association, NPMA, and Maryland Pest Management Association, with over 300 years of combined team experience. When we treat for centipedes, we’re also identifying and treating the underlying pest issues that attracted them.
Are House Centipedes Dangerous?
Here’s some good news: house centipedes are generally harmless to humans. While they can technically bite, they rarely do and prefer to flee. In fact, they’re actually beneficial predators that help control other pest populations.
However, a large centipede population is a warning sign. It usually means you have enough prey insects to support them—which points to a bigger pest problem that needs attention.
When Centipedes Indicate a Bigger Problem
In my years as a licensed technician, I’ve learned that centipedes are often the symptom, not the main problem. When homeowners in Bethesda, Germantown, or Kensington call about centipedes, our inspection often uncovers:
- Silverfish infestations in humid areas
- Cockroach problems in kitchens and basements
- Spider populations in crawl spaces
- Carpet beetle activity in closets and storage areas
- Moisture issues that attract multiple pest species
Treating only the centipedes without addressing these underlying issues means they’ll keep coming back.
According to Penn State Extension, “reduction in the centipede food source is the first step in managing a house centipede population.” This is why professional pest management focuses on the whole picture—not just the pest you’re seeing, but the conditions attracting it.
