Do you have moles, voles, or shrews? Yes, Michiganders, we have all three of these little culprits right here in West Michigan.
Moles live underground in tunnels feeding on grubs, beetles, earthworms, and other food sources found in the soil. Moles don't really eat plants, they are insectivores. Homeowners will see ridges of their tunnels with ocassional mounds of dirt.
Voles make trails through the grass or snow and are primarily herbivores. They prefer roots, bulbs, bark, and seeds of ornamental grasses & plants. Voles will make tunnels / trails on top of the ground and sometimes are referred to as a meadow mouse with rounded ears.
Shrews will reuse tunnels made by both moles & voles and will occasionally invade outbuildings. Shrews feed on slugs, insects, seeds and roots. Shrews have a longer pointed snout and their front feet are not enlarged like a mole or vole.
