Signs of centipedes in San Diego County

Centipedes are fast and avoid light, so most sightings happen when a light switches on in a damp room at night. Check bathrooms, garages, and crawl space entrances first.

How to tell if you have centipedes

  • Sightings in damp rooms at nightCentipedes are most active after dark in bathrooms, laundry rooms, and garages.
  • Fast, erratic movement when disturbedUnlike slower pests, house centipedes dart for cover the moment they are exposed to light.
  • Presence of other small insectsCentipedes follow their prey, so silverfish, spiders, or ants nearby often mean centipedes are not far behind.
  • Visible dampness or condensation nearbyFogged windows, damp baseboards, or a musty smell in the same area as the sighting.
  • Activity in crawl spaces and garagesUndisturbed, dark, humid corners are the most common daytime hiding spots.

What to do next

Run bathroom and laundry exhaust fans consistently, fix slow leaks right away, and keep garages and storage areas decluttered so centipedes have fewer places to hide.

Common questions

Are house centipedes in San Diego County dangerous to people or pets?

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.

Why do I mostly see centipedes in the bathroom?

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

Does seeing a centipede mean I have a bigger pest problem?

Often yes. Centipedes hunt other insects, so regular sightings can point to an underlying spider, silverfish, or ant population worth checking.
