Please be sure to read the product label of any insecticide you choose to use to get information on the personal protective safety gear you will need. In most situations, it is recommended that you wear long pants, a long sleeved shirt, closed toe shoes with socks, chemical resistant gloves, and goggles. In areas where ventilation is poor, a manufacturer may recommend you wear a mask or a respirator.

Where do House Centipedes live?

House centipedes are found all over the world. They prefer to live in damp, dark places. This includes basements, crawl spaces, bathrooms, and closets. Outdoors, they can be found under rocks, leaves, and in mulch.

House Centipede Lifecycle:

Centipedes are born with as few as four pairs of legs, gaining a new set with each molting. They go through three lifecycle stages, molting six times before becoming an adult.

  • Eggs: Female house centipedes lay their eggs in the spring. They will lay between 35 and 150 eggs at a time. The eggs are small and white. They are usually laid in groups.
  • Nymphs: Nymphs are baby centipedes. They hatch from the eggs in 2 to 4 weeks. Nymphs look like adults, but they are smaller. They will molt (lose their skin) 5 to 15 times before they become adults.
  • Adults: Adult house centipedes can live for up to 3 years. They will molt every few months.

Do Centipedes bite?

Yes, centipedes have poison claws behind their heads that they use to poison and paralyze their prey (small insects). These claws are weak and rarely penetrate human skin. There have been cases reported of people being bitten by centipedes but a centipede bite is no worse than a bee sting, and they bite humans very infrequently. More than anything, they are a nuisance; they do not threaten the health of humans or pets in a home.
