Why Centipedes and Millipedes in Marysville Properties Are a Symptom, Not Just a Problem
House centipedes and millipedes are moisture-dependent arthropods that are rarely present in significant numbers unless the conditions supporting them are well established. In Marysville homes, their presence typically indicates excess moisture in basements or crawlspaces, accumulation of organic debris outdoors, or an underlying insect population (house centipedes prey on other insects).
Millipedes, which feed on decaying organic matter, often invade in large numbers after heavy rainfall — migrating from outdoor mulch and leaf litter into foundations and through gaps in the building envelope. Centipedes follow the insects they feed on.
Identifying Which Species You Have in Marysville
Centipedes are fast-moving predators with one pair of legs per body segment. The house centipede can deliver a mild bite if handled. Millipedes are slow-moving detritivores with two pairs of legs per segment. They do not bite but produce defensive secretions that cause skin irritation in some people.
Treatment Approach in Marysville
Our Marysville treatment approach runs on two tracks simultaneously. Residual perimeter treatment and interior application reduce the active population. Moisture assessment, entry point sealing, and harborage reduction advice remove the underlying conditions — so the same problem does not return with the next wet season.
