Why Centipedes and Millipedes in Alameda 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 Alameda 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).
Millipede migration into Alameda properties typically follows predictable conditions: saturated outdoor soil pushes populations toward drier indoor environments, and foundation gaps provide access. Centipedes arrive independently — tracking the cockroaches, silverfish, and other insects that occupy the same basement and crawlspace environments they prefer.
Centipedes vs. Millipedes
Centipedes move fast — one pair of legs per body segment, predatory, and capable of a mild bite if directly handled. The house centipede is the most common indoor species and is attracted by the insects it hunts. Millipedes move slowly, coil when disturbed, have two pairs of legs per segment, and feed on decaying matter rather than other insects. They do not bite but produce defensive secretions that can irritate skin and eyes.
Treatment Approach in Alameda
Effective control requires both chemical treatment and environmental modification. Perimeter spray reduces the population entering the structure, while moisture and harborage reduction addresses the conditions sustaining the population.
