house centipede

  • Centipedes are elongated, flattened animals with one pair of legs per body segment.
  • The number of legs may vary from 10 to over 100, depending on the species. They have long jointed antennae.
  • The house centipede (photo above) is about an inch long, gray, with very long legs.
  • It lives outdoors as well as indoors and may be found in bathrooms, damp basements, closets, etc.
  • It feeds on insects and spiders.


If you see a centipede indoors, and can't live with it, escort it outdoors. Centipedes are beneficial by helping to control insect pests and spiders.
