Groundhogs live in areas that include fields, lawns, and along fence lines and roadsides. They live in burrows that they create 4-5 feet underneath of the ground. The groundhogs mound a pile of dirt next to their burrow entrance that can be 10-12 inches in diameter. The burrows can run as long as 25-30 feet and they generally have two entrances as a means of escape. If they create their extensive burrows underneath of the foundations of homes or other buildings they can significantly weaken the structural integrity of those buildings.
Groundhogs are vegetarians and are most active in the early morning and early evening hours. They feed on a wide range of plant materials that include: dandelions, broad-leaf weeds, grasses, and vegetables.
