Moles live underground and surface only occasionally. Their cylindrical bodies and powerful front claws are ideal for digging. They almost “swim” through dirt. Moles create a complex labyrinth of interconnected chambers by burrowing both deep and close to the surface, where they often leave visible ridges. Mole hills are places where the mole has pushed up earth above the surface. They have very poor sight and feed mainly on worms and insect larvae that they find by the sense of touch and smell. They do not eat roots or tulip bulbs. That is the work of voles. Moles are usually territorial, so all of those tunnels and mounds in your yard might be the work of a single animal.
