FAQ

Centipedes Questions Answered

Common questions about identification, prevention, and treatment

Are centipedes dangerous?

House centipedes can bite but rarely do, and bites are typically no worse than a bee sting. They're not aggressive and prefer to flee. Large outdoor centipedes have more painful bites but are seldom encountered indoors.

Why do I have centipedes in my house?

Centipedes need moisture and prey. Their presence indicates: 1) damp conditions somewhere in your home, and 2) other insects for them to eat. Fixing moisture issues and reducing other pests eliminates the conditions they need.

Should I kill house centipedes?

Centipedes are actually beneficial—they eat spiders, cockroaches, silverfish, and other pests. However, if their presence is intolerable, reducing moisture and treating entry points will decrease populations.
