Many people often mistake voles for moles. Moles make underground tunnels while voles make above-ground runaways. Moles eat earthworms, grubs, and insects whereas voles gnaw at the base of trees and shrubs and eat plants, especially grass and flower bulbs.
During the winter, voles will tunnel under the snow and create winding trails about 2 inches wide, as they feed on grass. In most cases, raking up the loose grass will take care of the problem. The damage is mainly cosmetic and the turf will recover on its own in time.
If you have a large vole problem, using mouse control baits will help control voles. It is a good idea to use these products in a weatherproof bait station. These bait stations help to protect non-target pests and keep the mouse control products from getting wet. Mouse snap traps can also be effective when placed perpendicular to the runways with a peanut butter-oatmeal mixture or apple slices as bait.
