Woodchucks (Groundhogs)

Woodchucks can cause more damage to the structure of a home than almost
any other animal. We have seen woodchucks collapse small decks, areas of
concrete, and some small sheds because of their elaborate tunneling systems.
A true hibernator, woodchucks spend the entire winter 4 or more feet below ground.
It is estimated that a woodchuck moves about 700 lbs. of dirt when digging his den. Woodchucks are vegetarians and gardeners are quite familiar with them.
