Millipedes are cylindrical, many-segmented, worm-like animals. Most millipedes are not larger than 1 inch and can be easily distinguishedGiant orange millipede from centipedes in that they have 2 pairs of legs on each abdominal segment. Millipedes are mostly considered scavengers and feed primarily on decaying vegetation and leaf litter. They spend most of their lives in the soil where they also overwinter. In the spring, millipedes lay between 20 and 300 eggs in the soil which hatch in several weeks. Millipedes sometimes migrate in large numbers, particularly after heavy rains in the late summer or as weather cools. Millipedes can climb walls (inside and outside) easily and will often enter homes through foundation cracks above ground level as well as through seams under doors.
