Moles are technically an insectivore (eats  insects); not a rodent.
Moles feed primarily on earthworms and white grubs, but will also eat millipedes, centipedes, beetles, spiders, and other insects that venture into their underground tunnels.
As the moles tunnel underground, they uproot the soil and expose roots of trees, shrubs, plants, and grass.
Moles have a high metabolism rate and  eat from 70% to 100% of their weight each day. This is because they burn so much energy digging.
