Reducing the soil insect population can discourage moles. One main insect that the moles prefer is white grub. The white grub is the larva's form of the Japanese Beetle, Asiatic Beetle, May Beetle, or other beetle species. Another control method is using mole traps. Pine voles and meadow voles are often called field mice.
Voles feed on bulbs, plant roots, root crops and tree bark and roots.
We have known them to girdle and kill a tree in one winter. They are also pests in perennial flower beds. Vole damage can be more damaging than insects or diseases. We have known voles to use mole trails. If plants are disappearing, you probably should suspect voles.
