While beneficial to the soil because they cultivate and aerate the dirt while tunneling for food, many people object to the unsightly molehills and tunnels that can destroy a beautiful lawn. According to the National Mole Hunters Association, moles can dig 100 feet of tunnels in a single day. They dig because they are looking for food such as earthworms, grubs and other insects. Be aware that when moles are present voles are likely to be around.
Voles and herbivores that travel through mole tunnels and servive by eating grass, bulbs, tubers, and herbaceous plants. While moles damage your plants when looking for insects, voles are actually eating your vegetables and flowers! Voles burrow into the root systems of shrubs and trees and they gnaw on tree trunks causing substantial damage.
