Voles look like house mice, but have a shorter tail, a rounded muzzle and head, and small ears. The vole has a dark brown fur coat with a grey stomach that turns white in the winter. Voles search for green plants and seeds during the day or night all year around. In the winter, they travel in tunnels beneath the insulating snow and make round holes in the snow when they come up to the surface. A common sign that voles may have been on your property, is if bark has been removed around the base of a tree.
People tend to think that the only way to deal with them is to dig up their lawn and replace it or run out to the garden center and order a load of topsoil and reseed the damaged areas. In most cases this is not necessary. If you are dealing with the tunnels left by Voles simply just lightly rake the damaged areas to ensure that the soil is getting enough air and sunlight. There is no need to worry as the grass roots will remain unharmed. Then once the ground temperatures warm up, the turfgrass will be able to repair itself quickly. Within a few weeks you will begin to notice an improvement.
