Beneficial Because:
Millipedes help process plant material into organic matter while aerating the soil.
Food and Habitat:
Millipedes are vegetarians, eating decomposing leaves and roots. They avoid midday heat by resting beneath mulch, which also provides cover from flooding rains.
Attracting More:
Populations of millipedes regulate themselves, though they have been known to eat potatoes and other root crops when too many were present. These are long-lived creatures that often live for several years.
