Nothing else gets a reaction quite like a house centipede. They move faster than you expect, those long legs make them look enormous, and they seem to appear out of nowhere — across your bathroom ceiling at midnight, out from under the washing machine when you move it, from the corner of the basement when you flip on a light. In Shawnee homes, house centipedes are a common occupant wherever humidity is high and other small insects are present. Miller Pest Solutions treats the moisture issues and harborage areas that support them, and addresses the broader pest conditions that keep centipede populations fed and active.

Signs of a Centipede Problem

  • House centipedes — yellowish-gray, up to 1.5 inches long with 15 pairs of very long legs that extend well beyond the body width — seen running across basement floors, bathroom walls, laundry rooms, or kitchen areas. Fast movement is their most striking feature.
  • Centipedes found trapped in bathtubs and sinks, where smooth surfaces prevent them from climbing out. A centipede in the bathtub in the morning is an extremely common sign of an indoor population.
  • Frequent sightings — more than one or two per week — indicating a population has established rather than occasional individual strays entering from outside.
  • Presence of moisture: visibly damp basement walls, condensation on cold pipes, musty odors in crawl spaces, or known flooding issues. Centipedes track moisture.
  • Other pest activity — silverfish, small spiders, earwigs, flies, or roaches — which constitute the prey base that sustains centipede populations. If you have centipedes regularly, something is feeding them.

Why Centipedes Are Common in Shawnee

House centipedes need two things to thrive: moisture and prey insects. Shawnee basements, particularly in older homes and established neighborhoods, often have both. Kansas summers are humid, and that humidity infiltrates basements and crawl spaces without aggressive dehumidification or proper drainage. Where humidity stays elevated, silverfish, earwigs, and small spiders establish. Where those insects are present, centipedes follow.

Here’s the thing about centipedes that’s often missed: they’re predators. The house centipede (Scutigera coleoptrata) feeds on spiders, silverfish, roaches, flies, small moths, and other arthropods. Regular centipede sightings in your Shawnee home don’t just indicate a centipede problem — they indicate an active prey insect population supporting them. Miller Pest Solutions treats the centipede issue, but we also look at what’s sustaining it.

Centipedes enter homes from the exterior through foundation gaps, crawl space vents, utility penetrations, and any ground-level opening. They follow moisture gradients — high humidity outside the foundation draws them toward the building, and they transition through any gap into the basement or lower-level spaces where conditions are even more favorable.

In Shawnee’s older neighborhoods, homes with partial crawl spaces, block foundation walls, or older plumbing that drips are particularly prone to centipede problems. These structural features create the moisture conditions centipedes need.

Our Centipede Control Process

Centipede control is really a moisture and prey-reduction problem as much as a direct pest problem. Spray treatments alone without addressing humidity and the prey species will require repeated visits.

  • assessment and assessment — We evaluate moisture conditions in basement and crawl space areas, identify harborage sites, and look for the prey insects supporting the centipede population. This shapes the treatment approach.
  • Residual insecticide treatment — Applied to basement walls, floor-wall junctions, crawl space areas, and other harborage zones. Effective against centipedes and the prey insects that sustain them simultaneously.
  • Moisture recommendations — Dehumidifier placement, crawl space vapor barrier installation, drainage improvement recommendations. Long-term centipede control requires bringing relative humidity below the range that supports prey insect populations.
  • Entry point sealing — Foundation cracks, crawl space vents, utility penetrations — the routes centipedes use from outdoor soil into interior basement spaces. Sealing these cuts off the exterior population from replenishing indoor populations.
  • Broader pest program — If silverfish, earwigs, or other prey species are clearly present alongside centipedes, we’ll recommend appropriate treatment for those as well.

One practical note: house centipedes are actually somewhat beneficial in that they consume other pest insects. Some homeowners choose to tolerate occasional centipede sightings for that reason. But frequent, widespread centipede activity inside a home — particularly in living areas above the basement — indicates a moisture and pest population problem that warrants professional attention. Tolerating centipedes as pest controllers doesn’t address the conditions driving their population.
