Damage to Your Yard and Home

Groundhogs are a well-known nuisance across Michigan, frequently causing costly damage to residential properties. These animals are powerful diggers and can burrow through nearly any type of soil—whether sandy, rocky, or clay-based. Because they work quickly and often go unnoticed, it’s important to recognize the signs of activity early and take action before the damage becomes extensive.

So why are groundhogs such a problem? Here are the most common issues we encounter:

Burrowing Under Cement and Along Foundations

Groundhogs often dig beneath concrete slabs, including garage floors, shed pads, patios, and home foundations. As they remove the supporting soil, the concrete structure above begins to weaken. This can eventually lead to cracks, sinking, or uneven surfaces—resulting in expensive repairs.

We’ve responded to numerous cases where the damage had already progressed too far by the time we were called. If you notice dirt piles forming near your garage, shed, or home, don’t ignore them. Early intervention can save you thousands in structural repairs.

Damage to Drainage Systems and Underground Lines

With a biological digging machine in your yard, it’s not uncommon for groundhogs to run into things they shouldn’t. From drain tiles to buried wires and even invisible pet fences, their extensive tunnels often interfere with underground infrastructure.

Groundhog holes are typically 8 to 10 inches wide. Their burrows can run 2 to 5 feet deep and stretch as far as 40 feet long. If any of these tunnels intersect with critical lines or systems, the damage may be both hidden and costly.

Abandoned Burrows Invite Other Wildlife

When groundhogs move on, they often leave their burrows behind—creating ideal nesting sites for other animals. In the spring, these abandoned dens are especially attractive to wildlife looking for a safe, dry place to raise young.

One of the most common secondary invaders? Skunks. We’ve removed entire litters—sometimes 12 or more—from a single property after they took up residence in former groundhog tunnels beneath decks, garages, and additions. If you see old burrows around your home, it’s wise to fill them in before new residents move in.

Garden Destruction

Second only to rabbits, groundhogs are infamous for destroying backyard gardens. They’ll mow through fresh vegetables and plants without hesitation.

While this may seem like a minor inconvenience to some, for those who put time and care into planting, nurturing, and growing a garden, it can be heartbreaking. A single groundhog can devastate your hard work in a matter of hours. Before the growing season begins, inspect your perimeter, fences, sheds, and outbuildings for any signs of burrowing activity.

Final Thoughts

Although groundhogs don’t pose a direct threat to humans or pets, their long-term presence can result in serious property damage and ongoing wildlife problems. If you spot one running under your shed or munching on your vegetables, don’t wait for the damage to escalate.
