Key Points

  • Millipedes are cylindrical in shape, have 2 pairs of legs per body segment, and short antennae. They vary in length from less than an inch to more than two inches.
  • The most common millipedes that invade homes are brown and 1 to 1 1/2 inches long.
  • Millipedes live outdoors and feed on decaying organic material or plants.
  • They occasionally enter homes but cause no damage.

Management

  • Prevent them from coming in by eliminating gaps around doors and screens.

  • Remove decaying vegetation, leaf litter, or mulch, and reduce moisture around the foundation.

  • Sweep up and return outdoors any millipedes found indoors. 

  • Chemical control is not necessary.
