Two names, one animal. The woodchuck is a stocky robust member of the ground squirrel family. Adult males can weigh up to 12 pounds. They are a common sight in suburban areas and prefer to dig their dens in the sides of hills, in fields, and under decks & sheds. Burrows have openings that are approx. 12 inches in diameter, sometimes reaching 60 feet in length. Woodchucks are most active at dawn & dusk. We generally have little to no trouble trapping woodchucks, as long as we can locate their burrows. We also offer exclusion at your request.
