VOLE
Voles can get into houses, but that is not their usual environment, and they will not stay and set up a nest. They are also known as Meadow mice, Field mice, and Orchard mice. They are about twice as large and heavy as a House mouse, the body being 5-6 inches long with a shorter tail. Voles can be a problem for crops, fruit trees, ornamentals, and landscaped areas. They feed on grasses and just about any green vegetation.

Life Cycle
Nests are built of grasses or other vegetation on or near the surface. Voles give birth in three weeks after mating. Three to nine young can be produced in each litter, with litters peaking in the spring and somewhat in the fall, so more than one generation can be produced each year.
