Voles and Vole Control

The Vole is often called a meadow mouse or field mouse, and it averages the size of a large mouse or small rat. They are found to weigh anywhere from ½ ounce to 3 ounces. The vole has small eyes and ears, the latter being mostly hidden in its fur.

Although it is generally believed that the vole is nocturnal, they may be active at any time. The vole will create shallow surface tunnels much like the mole in its search for food, but it is also just as likely to be found foraging on the surface. Most voles are social animals and many types will share their burrow with a handful of loosely related individuals.

North America is home to 23 species of vole: Below, we will discuss seven of the widest ranging and most destructive of these 23 species. The locations where these particular voles live may be found on our Vole Geography page.

• California vole, Microtus californicus, has brown colored fur usually with a reddish hued section down the center of the back; its underside is typically blue-gray to white. The California vole spends very little of its time on the surface. It will grow to between 5.5-inches and 8.5-inches long and weigh between 1.3 ounces and 3.75 ounces.
