Millipedes are brown or black but can also be orange or red. They range in size from 5/8" to 4 inches in length. They are long cylindrical, many segmented worm-like creatures. Some species appear to be flattened. Every millipede has two pairs of legs attached to each apparent body segment.
Millipedes are found outdoors in situations where there is moisture and decaying organic matter. They are common under trash, grass clippings, mulch, rotting firewood, etc. They can invade homes and other structures. Millipedes usually die within a few days of entering a structure unless there is a high moisture and food supply source.
Millipede Life Cycle
Females lay 20 to 300 eggs in nests in the soil. The eggs hatch after several weeks. The young initially have only three pairs of legs with seven segments. They reach sexual maturity in two to five years.
