New York Centipede & Millipede Infestation — Reading the Underlying Cause
Centipedes and millipedes are not random visitors in New York homes — they are indicators. High moisture in crawlspaces or basements, organic debris close to the structure, and insect populations in wall voids or lower floors all attract these arthropods reliably. Treating the population without addressing these conditions produces only temporary results.
Millipede migration into New York 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.
How to Tell Centipedes and Millipedes Apart
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 New York
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.
