Fort Collins Centipede & Millipede Infestation — Reading the Underlying Cause
Centipedes and millipedes require specific conditions to establish in significant numbers — and those conditions are almost always correctable. In Fort Collins 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.
Millipede migration into Fort Collins 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.
Identifying Which Species You Have in Fort Collins
Centipede: fast-moving, flat-bodied, one leg pair per segment, predatory. House centipedes are drawn indoors by insect prey and can deliver a mild bite if handled directly. Millipede: slow-moving, cylindrical, two leg pairs per segment, feeds on decomposing organic material. Millipedes coil defensively when disturbed and secrete compounds that cause skin and eye irritation in sensitive individuals — handle neither species without protection.
How We Treat Centipede & Millipede Infestations in Fort Collins
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.
