Centipedes

Centipedes are fast-moving creatures often found in damp, dark environments. Although their appearance may seem intimidating, they actually help control other insect pests and are typically harmless to humans.

Centipedes Uncovered: What They Are and How to Identify

Centipedes are long, segmented arthropods known for their many legs—ranging from 15 to over 170 pairs depending on the species. With flat, worm-like bodies and a pair of legs per segment, they also feature long, sensitive antennae on a distinct head.

In the U.S., centipedes typically range in color from yellowish to dark brown, often with stripes or markings. Their size varies greatly—from just 1/8 inch to up to 8 inches in the southern and southwestern states.

Where Centipedes Hide: Common Habitats

Centipedes thrive in moist, dark environments such as under rocks, mulch, leaf litter, and logs. Inside homes, they commonly inhabit basements, bathrooms, and crawl spaces. As nocturnal hunters, they use venomous jaws to capture and feed on insects, spiders, and other small invertebrates—making them useful in natural pest control.

Friend or Foe? The Role of Centipedes

Despite their fearsome appearance, most centipedes pose little threat to humans. Bites from smaller species are rare and typically result in mild pain or swelling similar to a bee sting. Larger species may deliver more painful bites, but they are generally not dangerous.

Signs of House Centipede Infestation

Centipede infestations are fairly common in areas with high humidity or during colder seasons when they seek warmth indoors. Their presence can also indicate underlying moisture issues or an existing pest problem. Recognizing and managing a centipede infestation is important not only for comfort but also to address potential root causes.
