Why Centipedes and Millipedes in Livermore 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 Livermore 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 feed on decomposing plant matter and are driven indoors when soil becomes saturated — typically after sustained rainfall or autumn wet periods. They enter through foundation gaps, door thresholds, and utility penetrations, often appearing in large numbers overnight. Centipedes enter separately, following the insect prey populations that live in the same damp conditions.
Identifying Which Species You Have in Livermore
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.
How We Treat Centipede & Millipede Infestations in Livermore
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.
