The house centipede is often seen in and around homes where dampness occurs such as closets, bathrooms or areas underneath homes. House centipedes are nocturnal and search for insects at night. This species of centipede reaches about 1.5 inches in length and has fifteen pairs of long, slender legs. The back legs are used to capture prey by using a "lassoing" technique. House centipedes are beneficial, but many people consider them a nuisance pest in the home.
