About

While sometimes called “thousand-leggers,” house centipedes actually only end up with up to 15 pairs of legs—a total of 30 legs. They’re usually yellow-gray in color and up to around 35 millimeters long. House centipedes will eat other insects that are in your house including silverfish, carpet beetles, cockroaches and spiders. Still, if you happen to spot a centipede in your home, you probably aren’t thinking of their good sides. Keep an eye on dark spaces (like a basement, attic, or closet) and remember that they like damp places, which is why it’s not uncommon to find them in a bathroom.

 

Is the House Centipede Dangerous?

Centipedes are mostly harmless to humans and while bites can happen, their forcipules (mouths) typically aren’t able to pierce human skin. If a bite actually occurs, it’s often similar to that of a bee sting, including redness and swelling.
