11 Proven Methods That Actually Work
No toxic chemicals · Works even in humid climates · Tested & updated.
House centipedes (Scutigera coleoptrata) are the stuff of nightmares for many people: long legs, lightning-fast movement, and they always appear when you least expect it. The good news? You can make them disappear forever — and you don’t need expensive exterminators or dangerous sprays.
We’ve tested every method below in real homes (including humid tropical climates) and updated everything for 2025. Follow these 11 steps in order and centipedes will stop choosing your house as their 5-star hotel.
Why Centipedes Love Your House (And How to Make Them Hate It)
House centipedes need three things to survive:
- Moisture (they breathe through their skin)
- Darkness
- Food (spiders, ants, silverfish, cockroaches, flies)
Remove any one of these and they leave. Remove all three and they never come back.
Most Common Entry Points in 2025
- Cracks around windows and doors
- Gaps under siding or brick
- Pipe penetrations (bathroom, kitchen, laundry)
- Foundation vents and crawl spaces
- Garage door seals
- Drain pipes and sump pumps
