Centipede & Millipede Control Livermore — What Their Presence Indicates
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.
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.
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.
