Centipedes are predators that live in moist areas. These nocturnal creatures hunt down insects and spiders at night. Centipedes are distinguished from millipedes in that they have only one pair of legs per body segment, while millipedes have two pairs of legs per body segment. They are seldom seen inside homes, except for the house centipede which may breed in crawl spaces and basements. The house centipede is recognized by its extremely long legs.

Indoors, they will usually be seen near baseboards and around doorways and windows. The house centipede may be observed wandering on walls in crawl spaces, basements, garages, and sometimes in other rooms of a house.
