Most centipedes are beneficial, but the large species found in the tropics, which may reach a length of up to 18 inches, can inflict painful bites. These, fortunately, are not found in Nebraska, but one species found in western counties may reach a length of 5 inches. Life Cycle Millipede eggs are deposited in masses in the soil. Young millipedes have fewer segments than the adult, but they add segments at each molt of the outer shell, or exoskeleton. Molting occurs 7-10 times before maturity.
Young millipedes mature the second year after hatching.
Some species may live for several years. Similarly, centipedes molt several times, adding legs and body segments with each molt. Affected plants may wilt and die and melons may develop rots caused by bacteria or fungi which are introduced by millipede feeding. If millipedes are abundant in mulches and litter in landscape plantings around homes and other buildings, they often enter through cracks and crevices. Once inside, they usually die unless basements are very moist.
