How to get rid of voles?
Though voles live in little tunnels, they spend time above ground eating grass and nibbling on other plants.The mouse-size voles leave a lot of small holes and connecting runways through the damaged grass they’ve been dining on.
One way to control voles is with mousetraps, which can be set at the entrance to their tunnels. But because of their high rate of reproduction, it can be difficult to keep up with them.
In raised beds, you can repel moles and gophers by using a barrier of welded wire on the bottom. Tilling in rows between crops may help. Using baits is an option, but will be dangerous to pets and other animals. As with all pesticides, read the label carefully.
Voles create smaller, inconspicuous burrows and trails, especially in turf. A vole's varied diet includes fruits and vegetables, seeds, roots and tubers. They often damage or kill trees and other woody plants in winter by chewing the bark off trunks.
Here is a useful Oregon State University pdf on Moles, Voles and Gophers.
