House Centipedes: identification, signs & control

Are house centipedes harmful?

House centipedes are mostly harmless to people. They rarely bite, and a bite feels like a mild bee sting. But they eat other insects, so seeing a lot of them usually means there's plenty of food: silverfish, spiders, roaches or ants. Rehoboth treats the moisture-prone areas where centipedes and their prey live, and helps you dry those spaces out.

Should I leave centipedes alone because they eat other bugs?

That's your call, but a big centipede population points to a bigger insect population. Treating the food source and moisture reduces both.
