House centipedes are easy to spot by their elongated, worm-like body with their many pairs of legs. They can actually have anywhere from 15-177 pairs of legs with one pair per segment, depending on the species. Interestingly, centipedes always have an odd number of pairs of legs.
In general, the body of a centipede is usually yellowish to dark brown in color, sometimes with darker stripes or markings. The heads of centipedes have a pair of long and sensitive antennae covered with dense hairs. They have small mouths and have large, claw-like structures that contain a venom gland. In fact, some centipedes have compound eyes containing as many as 200 optical units, while others have a cluster of simple eyes on each side of the hear or no eyes.
