What Are Millipedes?
Millipedes are slow, rounded, many-legged arthropods that curl into a coil when disturbed. Unlike centipedes, they are not predators; they feed on decaying plant material in moist soil, mulch, and leaf litter.
They are harmless but can migrate indoors in large numbers, especially after heavy rain or, conversely, during drought, seeking better moisture conditions.
How to Control Millipedes
Millipedes depend on damp organic matter, so control reduces moisture and harborage near the foundation and seals entry points.
- Move mulch, leaf litter, and grass clippings away from the foundation.
- Improve drainage so soil near the house is not constantly damp.
- Seal door sweeps, weep holes, and foundation gaps.
- Treat the perimeter and harborage zones during migration periods.

Common Questions
Are millipedes harmful?
No. They do not bite or damage homes. They are a nuisance when they migrate indoors in large numbers, and they dry out and die quickly inside.
Why did millipedes suddenly invade my home?
Heavy rain or drought drives mass migrations as they seek better moisture, pushing them through gaps near the foundation.
How do I keep millipedes out?
Reduce damp mulch and debris near the foundation, improve drainage, seal entry points, and treat the perimeter during migration periods.
