House Centipedes in Ontario
House centipede identification and moisture-focused prevention for basements and bathrooms.
What house centipedes look like
House centipedes have a flattened body with many very long legs and move rapidly. Their appearance is distinctive and often causes concern when one runs across a wall or floor.
Where activity develops
They favour damp, protected areas and feed on other small arthropods. Repeated activity can point to moisture and available insect prey.
Signs worth documenting.
Fast movement on basement walls
Sightings near drains or bathrooms
Repeated activity in humid rooms

Prevention depends on correct identification and the conditions supporting activity. These steps are a practical starting point.
Identification before treatment
