Centipede Control
House centipedes in your crawlspace, basement, or bathroom aren't just unsettling — they're telling you something. Where centipedes thrive, there's excess moisture and other insects feeding them. Tall Paul fixes both sides of the problem.
Centipedes in Middle Tennessee
The House Centipede (Scutigera coleoptrata) is the species most commonly encountered inside Middle Tennessee homes. It's immediately recognizable: yellowish-gray body, up to 1.5 inches long, with 15 pairs of long banded legs. It moves with startling speed along walls, floors, and ceilings — which is why first encounters in a bathroom at 2 a.m. tend to be memorable.
Unlike many nuisance pests, house centipedes are predators. They feed on cockroaches, silverfish, moths, spiders, earwigs, and other small insects. A home with centipedes almost always has a secondary prey population sustaining them — and a moisture problem creating the habitat both need. Crawlspaces with inadequate vapor barriers, bathrooms with persistent condensation, and basements with drainage issues are the most common harborage areas in Middle Tennessee construction.
House centipedes are mostly a nuisance pest. They are venomous — they use small forelegs to subdue prey — but bites to humans are rare and comparable to a mild bee sting. The real concern is what their presence signals: moisture problems and an underlying insect population that warrants inspection and treatment.

What's Attracting Centipedes to Your House
Centipedes don't randomly wander in — specific conditions in your home are drawing and sustaining them. Understanding the cause is the first step to solving the problem.
Crawlspace Moisture
Middle Tennessee's humid climate and frequent rainfall push moisture into poorly ventilated or inadequately sealed crawlspaces. High humidity and standing water create the damp soil environment that centipedes, silverfish, and other moisture-loving insects need to survive. A damaged or absent vapor barrier is often the root cause and the first thing we check on inspection.
A Population of Prey
Centipedes don't establish in a home unless there is food available. If you're seeing centipedes regularly, there are cockroaches, silverfish, spiders, or other small insects providing a food source — often in the same moisture-rich areas where the centipedes harborage. Treating the centipedes without addressing the prey population provides only temporary relief.
Exterior Harborage
Centipedes enter homes from the exterior — moving inward through foundation cracks, gaps under doors, crawlspace vents, and utility penetrations. Outside, they live under leaf litter, mulch beds, landscaping timbers, firewood piles, and stones directly against the foundation. Dense perimeter plantings and mulch that stays moist create ideal exterior harborage within a few feet of entry points.
Bathroom & Basement Conditions
Bathrooms with poor ventilation — insufficient exhaust fans, persistent tile condensation, or slow drains — create localized humidity that supports centipede activity, particularly around floor drains and under vanities. Finished and unfinished basements with sump pump areas, efflorescence on block walls, or any standing water will similarly attract and sustain populations.
Why Killing Centipedes One-at-a-Time Doesn't Solve the Problem
Contact sprays can kill the centipedes you see. They don't address the moisture driving them into your home, and they don't eliminate the insect population sustaining them. A month later, you'll have the same problem — because the underlying conditions haven't changed.
Effective centipede control is a two-part problem: eliminate the conducive conditions (moisture reduction, harborage removal) and apply a residual perimeter and crawlspace treatment that breaks the population cycle. This is exactly what Tall Paul's Quarterly Pest Control plan covers — perimeter treatment around the foundation and crawlspace application four times per year, timed to seasonal population peaks. Centipedes are one of the 20+ pest types covered under the quarterly plan without any add-on charge.
How Tall Paul Controls Centipedes
We treat the pest you see, address the conditions driving it, and cover it on every quarterly visit so the problem doesn't return with the next wet season.
Crawlspace Inspection & Assessment
We inspect the crawlspace for moisture issues, standing water, vapor barrier condition, and evidence of the secondary pest populations that centipedes feed on. If we find conditions that are actively worsening the problem — missing or damaged vapor barrier, standing water, blocked vents — we document and report those findings so you can address the root cause. A dry crawlspace is the most durable long-term solution.
Crawlspace Treatment
We apply a residual insecticide to the crawlspace perimeter, pier surfaces, and harborage areas — targeting the centipedes and the prey insects that sustain them. Crawlspace treatment is particularly effective because it addresses the primary harborage zone where populations are highest and where indoor invasions originate. We use products labeled for crawlspace use that are safe once dry and provide lasting residual action.
Perimeter Treatment
We treat the exterior foundation perimeter — the zone where centipedes are migrating from exterior harborage into the structure. This includes the foundation face, base of siding, and ground surface to a distance of 2 to 3 feet. We note any mulch beds, landscaping debris, or other harborage directly against the foundation and provide recommendations for reducing those conditions between service visits.
Covered Under Quarterly Pest Control
Centipedes are one of 20+ pest types covered under Tall Paul's Quarterly Pest Control plan. If centipedes return between scheduled quarterly visits, we come back at no additional charge — that's the guarantee. Our quarterly cadence is designed specifically for Middle Tennessee's seasonal pest pressure, timing treatments to coincide with spring emergence, summer peak, fall entry, and overwintering populations.

Related Pests We Treat
Centipedes share harborage and conditions with these pests. Where you find one, you frequently find the others — and all four are covered under Tall Paul's quarterly service.
Frequently Asked Questions
Straight answers to the questions we hear most often about centipedes in Middle Tennessee.
House centipedes can deliver a venomous bite if handled or threatened, but bites to humans are uncommon — they would rather flee than fight. When bites do occur, they typically produce a localized reaction similar to a mild bee sting: brief sharp pain and minor redness. No serious medical complications are associated with house centipede bites in otherwise healthy adults. The principal concern with centipedes is not danger to humans, but what their presence indicates about your home's moisture conditions and underlying pest population.
Bathroom appearances are almost always driven by moisture. Centipedes move toward humidity — a bathroom with persistent condensation, a slow drain with standing water, or an exhaust fan that's not adequately venting the space provides the humid microclimate they seek. In crawlspace homes, centipedes may also be entering through floor penetrations and pipe chases that connect the crawlspace to the bathroom sub-floor. Improving ventilation, fixing drainage, and crawlspace treatment together address the source of the problem.
That logic sounds reasonable but misses the bigger picture. The presence of centipedes means there are enough other insects in your home to sustain a centipede population — which is itself a problem that warrants treatment. Centipedes are not a reliable or effective pest control strategy. They also reproduce and eventually become a nuisance pest in their own right. And frankly, most homeowners don't want to share their bathroom with a 1.5-inch fast-moving bug, regardless of its dietary habits. Treating the centipedes and their prey is the right call.
Yes. Centipedes are among the 20+ pest types covered under our Quarterly Pest Control plan. Quarterly visits include perimeter treatment and crawlspace application where applicable — the two primary control points for centipede pressure. If centipedes return between scheduled visits, call us at 629-899-2287 and we'll come back out at no charge under the plan guarantee. A single quarterly service visit is often enough to knock back a centipede problem that has been building for a season.
