If you find a centipede at home, here is what it means…

Seal All Entry Points
Centipedes are remarkably thin for their length, which means they can fit through gaps that you might not initially take seriously. Walk the perimeter of your home’s lower level and look for cracks in the foundation, gaps where pipes or cables enter the building, spaces under exterior doors, and damaged or improperly sealed window frames. Weatherstripping, door sweeps, and appropriate caulking for cracks and gaps can significantly reduce the number of entry points available to centipedes and other crawling insects.

Eliminate Hiding Places
A cluttered home provides centipedes with exactly what they need: dark, undisturbed spaces where they can rest and hunt without interference. Reducing clutter — particularly in basements, storage rooms, and closets — removes the sheltered microenvironments they prefer. Pay particular attention to piles of clothing left on floors, stacks of cardboard boxes, bundles of stored materials, and any area that rarely gets disturbed during routine cleaning.

Address the Underlying Pest Population
Because centipedes are predators following their prey, eliminating their food supply is one of the most effective long-term strategies for reducing centipede activity. If you have noticed ants, silverfish, small flies, or other insects in your home, addressing those populations will reduce the centipedes’ motivation to remain indoors. Consider targeted treatments for the specific pests present rather than broad-spectrum approaches.

Natural and Low-Impact Repellents
Several natural options have shown effectiveness in deterring centipedes from specific areas. Diatomaceous earth — a fine powder made from fossilized aquatic organisms — can be sprinkled along baseboards, in corners, and around the perimeter of damp areas. It works by physically affecting the outer layer of insects and other arthropods that walk through it, and it poses no risk to humans or pets when used as directed.

Essential oils including peppermint, tea tree, and eucalyptus have repellent properties that discourage many crawling insects, including centipedes. Diluting a small amount in water and applying it along potential entry routes or in areas where centipedes have been spotted can be a useful supplementary measure.

Direct Removal
For individual centipedes spotted indoors, several simple methods work reliably. A glass jar placed over the centipede and slid under a piece of cardboard allows you to capture and release it outside without any risk of contact. A vacuum cleaner handles the task quickly if you prefer not to approach closely. Commercially available sticky traps designed for crawling insects can also be placed in corners, along baseboards, or in areas where sightings are frequent.
