Millipedes look similar to Centipedes, in that both are long slender arthropods (not "true" insects) with many legs. However, Millipedes are not as flexible or quick-moving as Centipedes, and Millipedes have two sets of legs per body segment, while Centipedes have one. Overall, Millipedes can have anywhere from 30 to 400 legs.

Damage From Millipedes

Millipedes are slow, harmless, burrowing insects that curl into a coil when disturbed. They seek out dark, moist places like the undersides of rocks, plant mulch or in plant debris. They feed on decaying organic matter and seldom harm living plants.  In autumn, they may become a nuisance as they move into homes seeking shelter and moisture. Overripe, fallen fruit and root crops can attract Millipedes.

Where Millipedes are Found Geographically

Millipedes are common throughout the United States.
