1/2 to 1-1/2 inch long, and tend to coil up when resting. They are brownish, oval, elongate animals with two pair of legs attached to most segments.
Millipedes normally live outdoors in damp places such as under decaying leaves and in mulch around outdoor plantings. In wooded areas millipedes live in piles of leaf litter. In dry weather they will migrate out of the litter piles as the leaves dry, and may enter buildings in large numbers.
They feed on damp and decaying vegetable matter as well as new roots and green leaves.
Since the millipede needs high moisture, reducing the unnecessary moisture would help reduce the appeal of an area. Millipedes feed and reproduce in decaying organic matter, so it may be necessary to remove plant mulch and leaves around the foundation in order to obtain complete control.
