Groundhogs are also referred to as woodchucks or whistle pigs. They are a member of the squirrel family. There are six species of woodchucks and marmots that occur in the United States. These animals commonly invade cropland and vegetable gardens, eating or destroying vegetables and landscape plants. Although groundhogs are slow runners, they scurry quickly to their dens when they sense danger. The primary predators of groundhogs are hawks, foxes, coyotes, bobcats, dogs and humans.
Groundhogs sometimes den in crawlspaces, so it is important to inspect the outside of the home for access points, such as broken vent covers or holes in the foundation. Homeowners should seal all cracks and crevices with caulk, repair any loose siding and install a mesh cover over chimneys and other exposed openings. If an infestation is suspected, give Capitol Exterminating a call.
