mole 1. A long, metal, bullet-shaped, enclosed tube with an internal manner that is driven by forced air through a connected nose. It is used to hammer its way under pavements to provide paths for pipes, wires, etc. 2. Burrowing insectivores (family Talpidae) with tiny eyes, concealed ears, soft fur, short forelegs pointing outward, flattened hands, and claws for digging. They primarily eat earthworms, larvae, and bugs, but will occasionally eat roots and nibble on greens. Tunneling near the surface can sever roots, heave plants, and damage lawns. Their tunnels are usually about 5 to 11 in underground and exits frequently are a raised saucer of earth with a depressed center where a hole may be visible. Trapping seems to be the most effective way of preventing damage from moles.
