Millipedes are a common North American household pest, ranging from 2.5 to 4 cm long with long, slender bodies. The common species in Canada and the United States are medium to dark brown in colour, and look similar to worms with legs spanning the length of their segmented bodies. Millipedes don’t bite or sting humans, but they can excrete a defensive fluid that can irritate the skin. They can also become a major nuisance to homeowners by creating an unsanitary environment, and attract other pests that prey on them.
Millipedes enter the home through basement doors and windows, crawlspaces, vents, weathered doors and windows or garages. Since they are able to climb the foundation of a home, it is possible for them to enter higher than ground level. Aside from the occasional sighting, there is almost no way to detect their presence. A professional eye is necessary to detect and remove all signs of millipedes, and eliminate a growing infestation.
