Groundhogs, also known as woodchucks, may look like harmless backyard visitors, but don’t let their chubby appearance fool you. When they start tunneling near your home, shed, porch, or business property, they can cause serious damage that’s both costly and dangerous.
At Dog Gone Wildlife, we often get calls from homeowners and commercial property managers who notice a burrow or two and assume it’s no big deal. But beneath the surface, groundhogs are capable of extensive tunneling systems that can compromise the structural integrity of buildings and lead to long-term problems.
Here’s why it’s crucial to take groundhog burrows seriously, especially when they’re near your foundation.
How Groundhogs Dig, and Why It Matters
Groundhogs are powerful diggers. Using their strong claws and sturdy bodies, they create complex burrow systems that often include multiple entrances, escape tunnels, and nesting chambers. A single burrow can be as long as 30 feet and up to 5 feet deep.
When these burrows are dug near buildings, decks, patios, or sheds, they can erode the soil that supports your structure. Over time, this may lead to:
- Shifting foundations
- Cracks in concrete slabs or walkways
- Sagging porches and decks
- Increased moisture intrusion or drainage issues
Structures at Highest Risk from Groundhog Tunnels
Not all structures are equally vulnerable, but the following are particularly at risk:
Sheds and Detached Garages
These lighter structures are often built on minimal or shallow foundations. A burrow beneath can lead to sinking, warping, or tilting of the entire structure.
Porches and Decks
Groundhogs love the shaded, protected area beneath a deck or porch. Their tunneling can weaken supports or footings and may create a tripping hazard as soil shifts or collapses.
Concrete Slabs and Walkways
If a groundhog burrows under a concrete slab, like a patio or sidewalk, it can crack, heave, or settle unevenly, posing both aesthetic and safety concerns.
Commercial Patios and Landscaped Areas
For restaurants, office complexes, and retail spaces, burrowing groundhogs can damage decorative landscaping, create liability risks, and drive away customers with unsightly holes or trip hazards.
Other Risks Beyond Structural Damage
While foundation and structural issues are serious, groundhog burrows can cause additional problems:
- Water Drainage Problems: Burrows can redirect water flow around your foundation, leading to pooling or basement leaks.
- Increased Pest Activity: Vacated groundhog burrows are often taken over by skunks, foxes, or other wildlife.
- Injury Risk: Large entry holes are a hazard for kids, pets, or customers walking through your yard or property.
What Should You Do If You Spot a Burrow Near Your Home or Building?
If you notice fresh dirt mounds, large holes (typically 10–12 inches wide), or sinking soil near your structures, it’s important not to ignore the signs. Here’s what we recommend:
Avoid DIY Traps or Blockages
Attempting to seal a burrow yourself can trap the animal inside or encourage more digging. Groundhogs may also become aggressive if cornered.
Don’t Wait Until Fall
Summer is the most active season for groundhogs. If you wait until fall, they may have already expanded their tunnels or attracted others to the site.
