Usually blamed for lawn damage caused by voles, the mole is another common rodent known for lawn damage. Like the vole, moles are not a problem inside the house. They primarily live underground. Moles have large claw-like front paws which makes them excellent diggers. They are about 4-6 inches in length with velvety fur that is usually black or grey in color and have very small, ineffective eyes and ears. Moles are also insectivores that primarily eat insects, especially earthworms.
