Why Centipedes and Millipedes in Portsmouth Properties Are a Symptom, Not Just a Problem

Centipedes and millipedes are not random visitors in Portsmouth 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.

Millipedes, which feed on decaying organic matter, often invade in large numbers after heavy rainfall — migrating from outdoor mulch and leaf litter into foundations and through gaps in the building envelope. Centipedes follow the insects they feed on.

Identifying Which Species You Have in Portsmouth

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 Portsmouth

Lasting centipede and millipede control in Portsmouth requires two parallel actions: chemical treatment to reduce the current population, and environmental modification to remove the moisture and harborage conditions that will sustain a new one. Perimeter treatment alone produces short-term results. Addressing root conditions produces lasting ones.

Treatment Methods — Centipedes & Millipedes in Portsmouth

Effective centipede and millipede control addresses both the active population and the underlying environmental conditions sustaining it.

Perimeter & Foundation Treatment

A residual insecticide barrier is applied to the full exterior perimeter — foundation walls, mulch beds, entry points, and the zone immediately adjacent to the structure where centipedes and millipedes concentrate before entering.

Basement & Crawlspace Treatment

Interior treatment focuses on the harborage and transition zones: basement floor perimeters, crawlspace wall junctions, utility areas, and the lower-level spaces where both species concentrate after entering through foundation gaps.

Moisture Assessment

Technician assesses moisture conditions in the basement, crawlspace, and around the foundation — identifying leaks, condensation issues, and drainage problems.

Entry Point Sealing

Gaps at the foundation, around pipe penetrations, and at door thresholds are identified and sealed to physically prevent entry.

Outdoor Harborage Reduction

Advice on removal of mulch, leaf litter, wood piles, and organic debris adjacent to the foundation.

Prey Insect Control (Centipedes)

House centipedes are predators — their presence in quantity means a prey insect population is supporting them. Where this is identified in your Portsmouth property, treating only the centipedes leaves the food source intact. Our integrated approach targets both, removing the centipedes and the reason they were there.
