Millipedes are technically arthropods, though they are often mistaken for worms or insects. They are detritivores, which means they eat decaying leaves and other dead plant matter. In other words, they benefit the environment because they recycle organic material. Millipedes prefer damp, dark places to live. In a yard they might congregate under piles of wood, leaves, or grass clippings. Inside a home they usually hide in basements, where the temperature is lower and there is more humidity in the air.
