Why Centipedes and Millipedes in Grand Junction Properties Are a Symptom, Not Just a Problem
Centipedes and millipedes require specific conditions to establish in significant numbers — and those conditions are almost always correctable. In Grand Junction properties, consistent centipede or millipede activity points to excess moisture in the basement or crawlspace, organic debris accumulation around the foundation, or an underlying insect population that centipedes are following as a food source.
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 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 Grand Junction
Our Grand Junction 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.
