House centipedes — the fast-moving, long-legged ones that appear out of nowhere in your bathroom or basement — are one of the more alarming household pest encounters in Riverside. They’re not dangerous, but they are a signal. House centipedes are predators that feed on other insects. A lot of centipedes means a lot of something else is living in your home. Miller Pest Solutions addresses both the centipedes and the underlying pest population driving them.

Signs of a Centipede Infestation

  • Seeing centipedes in bathrooms, basements, or crawl spaces — Finding house centipedes regularly, especially in moisture-prone areas, indicates an established population in those environments.
  • Finding them in bathtubs or sinks — Centipedes often fall into smooth surfaces they can’t climb. Finding them trapped in tubs or sinks is a common discovery and a reliable indicator of nearby activity.
  • Activity at night or in dark areas — Centipedes are primarily nocturnal. Seeing them during the day is unusual and suggests higher population pressure than normal.
  • High humidity or moisture in the basement — This is both a contributing condition and a warning sign. Where humidity is high, centipede prey items (silverfish, spiders, small roaches) also thrive, feeding the centipede population.
  • Spiders, silverfish, or small roaches also present — Since centipedes eat other insects, their presence alongside other pest activity confirms a broader infestation issue.

Why Centipedes Are Common in Riverside

Riverside’s Missouri climate brings humid summers that push moisture into basements and crawl spaces. House centipedes need two things: moisture and a food source. Missouri basements frequently deliver both. Homes with unfinished basements, crawl spaces, or older construction that allows humidity in are prime territory for establishing centipede populations.

The house centipede itself doesn’t cause structural damage or represent a health risk. But its presence is a reliable indicator that your basement or crawl space has an environment supporting a food chain of insects and arachnids. Treating centipedes alone without addressing the moisture and the prey species underneath is only a partial solution.

Our Centipede Control Process

Miller Pest Solutions approaches centipede control by addressing both the centipedes directly and the conditions that sustain them. Residual insecticide application in harborage areas — basement perimeters, crawl space entries, bathroom wall voids, utility areas — reduces the centipede population and their prey. Gel baits and targeted treatments in areas where prey species concentrate (silverfish, small spiders) remove the food source.

We recommend dehumidification for basements and crawl spaces with persistent moisture — a dehumidifier that keeps relative humidity below 50% significantly reduces the viability of the environment for centipedes and their prey. We’ll also identify and recommend addressing any active moisture infiltration: floor drains, sump pump operation, leaking pipes.

Exclusion of entry points at the foundation level — gaps around utility penetrations, missing door sweeps on basement entries — reduces the centipede population the structure can sustain.
