Walnut Centipede & Millipede Control
Moisture & Entry Point Treatment

A centipede or millipede infestation in Walnut signals conditions that need correcting, not just treating. Our technicians assess moisture levels, identify entry points, and apply integrated treatment that eliminates the population and removes the conditions that brought them in.

Walnut Centipede & Millipede Infestation — Reading the Underlying Cause

Centipedes and millipedes are not random visitors in Walnut 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.

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 Walnut

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.

How We Eliminate Centipedes & Millipedes in Walnut

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

Residual insecticide applied to basement perimeters, crawlspace edges, and lower floor areas — targeting the interior zones where centipedes and millipedes establish once they have entered the structure.

Moisture Assessment

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

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

Harborage reduction targets the outdoor population source directly. Mulch kept close to the foundation, leaf litter accumulation, stored wood, and damp debris piles are the primary outdoor harborage sites for millipedes in Walnut properties — our technician documents what is present and recommends specific changes.

Prey Insect Control (Centipedes)

Centipedes enter Walnut properties because prey insects are present. Where our assessment identifies a significant underlying insect population sustaining centipede activity, we treat the prey species as an integrated part of the control programme.

Millipede Invasion Seasons in Walnut

The highest millipede invasion events in Walnut properties follow a consistent pattern: late summer drought compacts outdoor populations into remaining moist areas, and the first significant autumn rainfall then saturates those areas simultaneously — triggering mass migration toward foundations. Properties with gaps in the building envelope and organic debris close to the structure experience the largest influxes.
