A centipede found near a doorway or window could have entered from the surrounding garden or outdoor environment.
If you repeatedly find them in the same location, inspect the nearby walls, baseboards, window frames, and door thresholds.
How to reduce entry
Seal suitable cracks around windows, doors, and foundations with materials appropriate for the surface. Install door sweeps where gaps exist beneath exterior doors, and repair damaged screens.
For openings around pipes or cables, use an appropriate sealing material while ensuring that ventilation, drainage, and fire-safety requirements are not compromised.
Do not automatically assume that every centipede found near a drain came directly through the plumbing. Some may simply be attracted to the surrounding damp area or may have entered through another nearby opening.
Closing entry points is one of the most practical long-term steps for reducing unwanted encounters.
4. Clutter Provides Hiding Places
Centipedes prefer locations where they can remain concealed and protected.
Inside a home, piles of cardboard, unused storage boxes, bags, laundry, and items placed directly against walls may provide dark spaces in which small creatures can hide.
Clutter can also create favorable conditions for other pests. When insects establish themselves in undisturbed storage areas, centipedes may follow because prey is available.
Places worth inspecting
Pay particular attention to garages, storage rooms, closets, utility spaces, and areas beneath furniture that rarely moves.
Cardboard boxes stored directly on damp floors may create sheltered spaces for small arthropods. Stacks of old newspapers, unused containers, and items pushed into dark corners can make inspections more difficult.
This does not mean that a cluttered room automatically has centipedes. The concern is that clutter makes it easier for pests to remain unnoticed.
A simple approach to prevention
Store items in suitable, sealed containers where practical. Keep frequently used spaces accessible for cleaning, and avoid leaving unnecessary materials in damp corners.
Move stored items away from walls when checking for pests, and inspect boxes or outdoor materials before bringing them inside.
You do not need to maintain a perfectly empty home. The aim is to reduce undisturbed hiding places and make it easier to identify moisture or pest problems early.
5. Outdoor Conditions Can Push Centipedes Indoors
Centipedes are not exclusively household creatures. Many species live outdoors, where they occupy moist soil, leaf litter, gardens, and spaces beneath rocks or decaying wood.
Sometimes they enter buildings because the surrounding environment offers favorable shelter, or because outdoor conditions change.
Heavy rain, changes in ground moisture, and hot or dry weather can alter where small animals seek refuge. The precise response depends on the species and local conditions, so there is no single weather pattern that explains every indoor sighting.
Check the area around your home
Look at the spaces immediately surrounding your exterior walls.
Dense piles of leaves, rotting wood, discarded boards, stones, and thick layers of damp organic material can provide hiding places for centipedes and the small animals they eat.
Overgrown vegetation close to the foundation may also keep the surrounding ground shaded and moist.
You can reduce these favorable conditions by removing unnecessary debris, maintaining vegetation, and allowing the soil near the house to drain and dry appropriately.
If you keep firewood outdoors, store it away from the building where practical and inspect pieces before carrying them indoors.
The purpose is not to eliminate every centipede from your garden. Centipedes play a role in natural food webs by preying on other small animals. The objective is to reduce the chance that they will find shelter and food inside your living spaces.
6. Why Do Centipedes Often Appear at Night?
Many centipedes are most active after dark. During daylight hours, they may remain hidden in cracks, beneath objects, or in damp, sheltered areas.
At night, they emerge to search for prey.
This behavior helps explain why someone might see a centipede racing across a bathroom floor late in the evening, even though the room appeared empty earlier in the day.
Why do they move so quickly?
Centipedes have elongated, segmented bodies and one pair of legs per body segment. Many species can move rapidly when searching for prey or escaping a disturbance.
Their sudden movements can make them seem aggressive, but fast movement alone does not mean they are trying to attack people.
In many cases, a centipede is attempting to reach a hiding place.
If you encounter one, avoid chasing it with your bare hands. Keep children and pets away while you decide how to remove it safely.
