Warning: Centipedes & Millipedes Signal Moisture Problems

Pasadena Centipede & Millipede Control
Moisture Assessment & Perimeter Control

A centipede or millipede infestation in Pasadena 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.

Warning Signs to Watch For
  • Fast-moving many-legged insects in bathrooms
  • Slow-moving, coiling millipedes found in basement or crawlspace areas
  • Large numbers of millipedes accumulating near the foundation or entry points
  • Concentrated activity near drains, sump pump pits, or water heater areas
  • Damp basement, crawlspace, or garage conditions
  • Sudden increase in activity after heavy rainfall or prolonged wet weather

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

Centipedes and millipedes require specific conditions to establish in significant numbers — and those conditions are almost always correctable. In Pasadena properties, consistent centipede or millipede activity points to excess moisture in the basement or crawlspace, organic debris accumulation around the foundation, or an underlying insect population that centipedes are following as a food source.

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 Pasadena

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.

Our Integrated Treatment Approach for Pasadena Properties

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.

Treatment Options for Pasadena Properties

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

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

Prey Insect Control (Centipedes)

Centipedes enter Pasadena 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 Pasadena

In Pasadena, millipede invasions peak in two predictable windows: autumn, as soil temperatures drop and moisture increases, and after sustained heavy rainfall at any time of year. The combination of saturated outdoor soil and available foundation access drives rapid mass migration toward drier interior conditions.
