Hatchlings are born with four pairs of legs and gain additional pairs with each molt. House centipedes molt six times before they are mature. Centipedes eat flies, spiders , and other soft-bodied arthropods. The largest North American centipede preys upon vertebrates such as small lizards and baby mice, as well. Poison is injected to subdue the prey animals.
Centipedes are nonaggressive and their venom is mild.
The bite of a centipede is painful at its worst. The affected area may be tender for a few weeks and heals slowly. Tetanus is the main concern. If bitten, allow the wound to bleed, then was with soap and water and apply antiseptic. Consult a physician for information regarding tetanus shots.
