Voles don't come in the house. oles are not mice. They are a member of the muroid family, which includes the beavers, squirrels, muskrats and the nutria. Voles are most closely related to the beaver, which is why they look like beavers and have similar habits. They are also quite similar to prairie dogs. Like prairie dogs, vole colonies can be found all over North America.
Voles are about 2 inches long, weigh about 1/2 pound and have large ears and black, bushy tails. They are nocturnal (active at night) and feed on seeds, grasses, and insects. Voles live in burrows that are usually located under ground or along streams. They spend most of their time alone in their colonies, but will come out to eat and drink.
Voles are very social animals. They live in colonies of up to 30 individuals. They communicate with one another by tapping on the surface of the soil or ground with their front feet. When they are disturbed, they freeze, hunker down and may even curl up into a ball.
