How to get rid of centipedes in San Marcos, CA
House centipedes turn up in San Diego bathrooms, garages, and laundry rooms wherever damp, dark conditions give them cover during the day. They look unsettling with their long legs and quick movement, but they are actually hunting the smaller insects already inside your home.

The house centipede is the species most commonly found indoors in San Diego County, recognizable by its long antennae, banded legs, and fast, erratic movement.
San Marcos 1990s-2000s tract construction through San Elijo Hills, Lake San Marcos, and the streets running off Twin Oaks Valley Road sees heavy Argentine ant pressure, web spider activity, and seasonal yellow jacket nest formation in irrigation boxes and lawn voids. Cal State San Marcos student-housing turnover drives bed bug pressure in adjacent rental stock.
Why centipedes show up here
Escondido and San Marcos see less centipede pressure overall given the drier inland heat, but poorly ventilated bathrooms and laundry rooms still collect enough moisture to draw them in.
How to get rid of centipedes: step by step
- Run a dehumidifier or exhaust fan in damp rooms Bathrooms, laundry areas, and garages with poor airflow are the main centipede hot spots, and cutting the humidity removes the draw.
- Fix leaks and standing moisture Check under sinks, around water heaters, and in crawl spaces for the damp conditions centipedes need to survive.
- Reduce the insects they are hunting Centipedes follow their food source, so addressing spiders, silverfish, and other small insects removes what is drawing them in.
- Seal gaps around baseboards and pipes Caulk entry points where centipedes travel between damp areas and living spaces.
- Clear clutter in garages and storage areas Stacked boxes and undisturbed piles give centipedes daytime hiding spots close to the house.

They can bite if handled, but it is rare and usually no worse than a bee sting. House centipedes actually help by eating other household insects.

Bathrooms hold the most consistent humidity in a house, and centipedes need that moisture to survive. Running the exhaust fan longer cuts activity fast.
