The house centipede can grow to almost 2 inches long.
The house centipede can be shades of brown, orange or yellow in color with very long antennae and three dark stripes running down the top of the body. It has 15 pairs of legs, one per body segment, that extend well out to the sides and are typically as long as the body. The last pair of legs is extremely elongated.
The house centipede is often seen darting across floors at high speed then stopping and becoming motionless before taking off again. It is a fast moving animal that almost looks like a feather moving across the floor or wall. The house centipede is nocturnal and outdoors can be found hiding underneath mulch or other landscape material. They are often found indoors where they gravitate toward damp areas such as closets, bathtubs, sinks, basements and crawl spaces.
House centipedes are predators who feed on flies, roaches and spiders as well as insect larvae.
House centipede eggs are laid in spring and early summer. A Female will produce anywhere from 60 to 150 eggs. When the larvae hatch, they have four pairs of legs and go through several transformations before they are mature and have all 15 sets of legs.
The house centipede captures its prey by half pouncing and half lassoing it with its legs. It can capture several prey items at one time and feeds on one specimen while holding the others with its numerous appendages. The house centipede does have venom, but its stinging apparatus behind the jaws is too weak to be able to penetrate most human skin.
