Millipedes
Millipedes are slow-moving, cylindrical arthropods with two pairs of legs per body segment that curl into a defensive coil when disturbed. They live in moist soil, leaf litter, and mulch, feeding on decaying organic matter. During certain conditions - typically heavy rain followed by dry weather, or population explosions - millipedes migrate in large numbers and invade homes through ground-level gaps. These mass migrations can involve hundreds to thousands of millipedes and are one of the most dramatic occasional invader events homeowners experience.

Key Behaviors
Millipedes are moisture-dependent detritivores that cannot survive long indoors. Mass migrations are triggered by heavy rain, flooding, or population peaks that push them out of their normal habitat. They enter homes through foundation cracks, door thresholds, and basement windows. Once indoors, they die from desiccation within a day or two. They are most active at night and accumulate in garages, basements, and ground-level entries.
Risks & Concerns
Millipedes do not bite, sting, or damage structures or belongings. Some species secrete defensive compounds that can stain skin, flooring, and fabrics. Mass migration events create significant nuisance situations with dead millipedes accumulating in and around homes. Their presence indicates excessive moisture and organic debris around the foundation.
