Centipede Control in Chico, CA | Professional Exterminator

Chico Centipede & Millipede Control
Moisture Assessment & Perimeter Control

Centipedes and millipedes in Chico homes indicate underlying moisture conditions and insect populations that attract them. Our specialists address both the immediate infestation and the environmental conditions sustaining it.

Chico Centipede & Millipede Infestation — Reading the Underlying Cause

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

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 Chico

Lasting centipede and millipede control in Chico 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 Chico

Treatment targets the current population and the moisture conditions driving it.

Perimeter & Foundation Treatment

Residual insecticide applied around the perimeter of the structure at the foundation, over mulch beds, and at all identified entry points.

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

Entry point sealing addresses the structural vulnerabilities that allow centipedes and millipedes to move freely between outdoor harborage and interior living space. Foundation gaps, pipe penetrations, and door threshold gaps are the most frequently identified access routes in Chico properties.

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 Chico properties — our technician documents what is present and recommends specific changes.

Prey Insect Control (Centipedes)

Centipedes enter Chico 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.
