CENTIPEDE
Centipedes are fast-moving predators that are commonly found around homes in Surprise and the surrounding cities. The smaller centipedes most people encounter are typically 1–3 inches long and have many pairs of legs along their long, flattened bodies, usually ranging from 15 to more than 30 pairs depending on the species. Despite the name “centipede,” which means one hundred legs, most species actually have far fewer than 100 legs. These centipedes prefer dark, damp hiding places such as bathrooms, laundry rooms, garages, and areas around plumbing. Because they rely on moisture, centipedes are often found in homes where there are cooler, humid areas, especially during warmer months. While their appearance can be unsettling, these smaller centipedes are generally harmless and help control other insects, as they feed on pests such as spiders, roaches, and other small insects.
​
Smaller centipedes are capable of biting if handled, but bites are uncommon and typically cause only mild, temporary irritation similar to a bee sting. Centipedes use modified front legs called forcipules to inject venom into their prey, but the venom of most small species is not strong enough to cause serious problems for people. Bites usually occur only if the centipede is handled, stepped on, or trapped against the skin, as they normally prefer to run away when disturbed.

Larger species, such as the living nightmare known as giant desert centipede, also live in the region but are much less commonly encountered inside homes. These centipedes can grow 6–8 inches long and are capable of killing small birds and rodents. Although the bite of a giant desert centipede can be lethal to children, seniors and people with weakened immune systems, most people recover after a few days of agonizing pain. If you are ever bitten by a giant desert centipede, we recommend seeking medical attention as a precaution.
