Several species in the Pacific Northwest
- Voles are native species of mice. They live in areas with heavy ground cover such as grasses.
- Voles are rarely a problem indoors.
- Voles make tunnels in grassy areas as shown in the photo (left).
- They gnaw on the bark at the base of trees and shrubs. This gnawing damages plants’ cambium (growing tissue).
- Tolerate voles if possible. They are part of the natural environment. Birds, snakes, and larger mammals prey on voles.
- Keep lawns and grassy walkways mowed to limit their habitat (upper right photo).
- Protect new plantings of fruit trees and restoration plants with plastic guards to exclude voles (lower right photo).
