The mole’s preferred diet is a carnivorous one: insect grubs, adult insects and earthworms. Neither the eastern mole nor the star-nosed mole is a rodent, and therefore any gnawing damage you detect on plants is unlikely to have been caused by moles. Rodents do, however, make use of mole tunnels to attack plants underground – making moles accessories to the crime!
Moles produce two types of tunnels, or “runways” in your yard. One runway runs just beneath the surface. These are feeding tunnels and appear as raised ridges running across your lawn. The second type of runway runs deeper and enables the moles to unite the feeding tunnels in a network. It is the soil excavated from the deep tunnels that homeowners find on their lawns, piled up in mounds that resemble little volcanoes.
