An occasional fast centipede appears at night
Occasional hunters can show up while chasing prey; one sighting does not define treatment needs.

House centipede sightings
Are house centipedes a problem that needs pest control?
House centipedes are often predators of other indoor insects and may appear where prey and humidity are available. A single sighting is usually a reason to check moisture and other pest signs—not automatic proof that you need a chemical treatment. Record where they run, reduce clutter and dampness you can safely address, and keep a photo for identification.
Consider a pest-management inspection when sightings are frequent, when other pest activity is obvious, when moisture problems persist, or when household members need a plan that avoids unsafe DIY pesticide use. Ask the professional to explain whether the focus is the centipedes, their prey, moisture or exclusion.
Put safety before diagnosisAvoid handling centipedes bare-handed; keep pesticide away from children, pets, food and water; never apply products into outlets, drains or inaccessible voids unless the label and a qualified plan permit it.

U.S. national guidance
What changes after you choose a location?
Choose a state to make the geographic boundary explicit.
A ZIP helps identify possible pest-service areas and current buyer coverage, but it does not prove jurisdiction, address-level coverage or an available qualified pest-management professional.
Applies nationallyThe safety and observation sequence on this page is general U.S. guidance.
Must be confirmed locallyPest identity, pesticide rules, applicator licensing, rental responsibility, prices, residential new-service eligibility, commercial or mobile-home eligibility, provider coverage and address-level serviceability require current evidence for the exact property.
Separate identification, exposure and property conditions
Which situation best matches the home?
Sightings cluster with damp areas or other insects
Prey insects and humidity are common drivers; treating only the visible centipede may miss the underlying pattern.
Notice next: Map moisture sources and other pest evidence in the same zones.
Several centipedes appear week after week
Repeated activity can justify inspection, but species and drivers still need on-site or photo-supported identification.
Notice next: Preserve a clear photo and a short log of dates, rooms and related pest signs.
Safe observation
What should you record before the call?
A short, factual description helps the next professional choose the right first inspection without treating a symptom as proof.
Sighting logs help inspection but cannot prove species, prey population, nest sites or whether treatment should target centipedes versus other pests.
What to record
- Clear photo for identification without handling the animal bare-handed.
- Frequency, rooms and times of sightings.
- Moisture sources, clutter and other insect or spider activity in the same areas.
- Prior pesticide use and whether pets or children use the affected rooms.
Stop and get appropriate help
- Anyone has a concerning bite reaction or another urgent medical symptom.
- Control would require unsafe access, opening electrical equipment or applying a product contrary to its label.
- Frequent sightings continue alongside other pest or moisture problems that need a written integrated plan.
Short answers
Questions people ask before the call
Are house centipedes dangerous?
They can pinch if handled, but they are often incidental predators. Medical urgency is uncommon; seek care for unexpected reactions. Identification still needs a photo or professional review.
Does seeing a house centipede mean I have a big infestation?
Not by itself. Frequency, other pest signs and moisture conditions matter more than a single sighting.
Should I spray every time I see one?
Usually no. Prefer moisture reduction, clutter control and inspection of related pests before any label-compliant product plan.
