Primarily herbivores, voles eat roots from trees or shrubs, bark, clover, seeds, bulbs and grasses as well as domestic garden plants such as cauliflower, lettuce, cabbage, sweet potatoes, spinach, beets, turnip, tomatoes, apple trees and olive trees. Voles are often considered pests because they gnaw at and eat domestic plants found in gardens as well as fruit trees. These gnaw marks will range from 1/8 of an inch to 3/8 of an inch, and are jagged, often appearing randomly around the plants.
The vole is an active animal and is up during the day and the night throughout the year. Although the vole does not hibernate, it will hide in its burrow system during cold weather, only coming out to eat. It also loves to live in areas where there is a lot of vegetation such as marshes, grassy fields and woodland.
The vole is a member of the rodent family and is typically 5 to 7 inches long. Sometimes they are called "meadow mice" instead, though their scientific name is Microtus pennsylvanicus. Voles mature quickly and to give birth often, so the population of voles in an area newly inhabited can grow quickly.
