BIOLOGY AND BEHAVIOR
Millipedes are a common anthropod found in Utah yards and gardens. Millipedes are typically dark brown and wormlike. On close inspection they have numerous small legs. Millipedes feed on decaying plants materials and thrive in moist areas such and lawns.
Occasionally they will move into homes, sometimes in very large numbers. The arid climate of Utah almost always kills the millipedes within a day or two. After dying, the hardened, curled body of the millipede may persist for a long period.
