Adult desert centipedes are 10 to 18 cm long and have a flattened body with one pair of legs per segment. They show many colour forms, often brown with a dark stripe on each side, and are called tiger-striped or multicoloured centipedes. They live in dry grasslands, deserts and forests of the southwestern United States and northern Mexico.

Does it bite or sting?

When provoked, they may bite, causing a painful wound with swelling, colour change and numbness. Their venom is considered medically relevant because it can cause muscle damage in laboratory animals.

How to get rid of it

Centipedes rarely need control unless they become a nuisance inside homes. Pesticides are seldom justified for centipede control.

Where it lives

They inhabit dry grasslands, forests and desert areas.

What it eats

Their venom can damage muscle tissue in prey, affecting cellular structures and respiration.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
