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

House centipedes and millipedes are moisture-dependent arthropods that are rarely present in significant numbers unless the conditions supporting them are well established. In Alpharetta 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, 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.

How to Tell Centipedes and Millipedes Apart

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.

Treatment Approach in Alpharetta

Lasting centipede and millipede control in Alpharetta 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.

How We Eliminate Centipedes & Millipedes in Alpharetta

Our Alpharetta treatment approach combines perimeter control with moisture assessment and entry point sealing — eliminating the population and the conditions that produced it.

Perimeter & Foundation Treatment

Perimeter treatment creates a residual contact zone at the foundation that intercepts migrating millipedes and centipedes before they reach entry points. Applied to foundation walls, soil adjacent to the structure, and mulch beds — the areas where populations accumulate between outdoor harborage and indoor access.

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

Moisture assessment covers the basement, crawlspace, and foundation perimeter — checking for active leaks, condensation on surfaces, inadequate drainage, and vapour barrier conditions. The assessment produces specific, actionable findings rather than generic dampness advice.

Entry Point Sealing

Foundation cracks, gaps around utility penetrations, door threshold gaps, and window well edges are identified, documented, and sealed — physically blocking the routes centipedes and millipedes use to reach interior spaces.

Outdoor Harborage Reduction

Specific guidance on mulch management, leaf litter removal, wood pile relocation, and organic debris clearance in the zone immediately adjacent to the foundation — the outdoor harborage area that sustains the populations entering your Alpharetta property.

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 Alpharetta property, treating only the centipedes leaves the food source intact. Our integrated approach targets both, removing the centipedes and the reason they were there.
