Woodchucks, groundhogs, and whistle pigs are all names for the same animal—Marmota monax—a member of the rodent family, closely related to squirrels. Their fur ranges in color from grizzled brownish-gray to nearly black, and their stocky bodies, short legs, and stubby tails give them a compact, low-to-the-ground appearance.

For gardeners, the mere mention of a woodchuck can spark anything from frustration to outright panic. These fast-moving animals can destroy a well-tended garden in just a few hours, devouring vegetables and flowers during early morning and late afternoon feeding times. Attempting to chase them off usually has little effect—they’re quick to return.

Beyond garden damage, woodchucks are notorious for digging large burrows around homes. These are often found beneath low decks, doorsteps, sheds, or any outbuilding built on a slab. Their burrow entrances are easy to spot: a wide 10–12 inch opening surrounded by a mound of freshly displaced earth.

If you’ve noticed holes around your property or damage to your garden, a woodchuck may be the culprit—and professional removal is often the most effective solution.
