groundhog in nature

Of all the wildlife that could cause problems to your property, groundhogs are among the strangest. They tear up your yard by digging burrows and holes—but why are they doing this? What makes groundhogs want to dig and dig and dig?

If you’re looking to stop groundhogs from wreaking havoc on your yard, it’s best to know what they’re doing in your yard and why they’re doing it. That’s where we come in! The experts at Varment Guard have compiled what you need to know about the groundhogs burrowing beneath your yard:

What are Groundhogs?

Groundhogs (Marmota monax), also known as woodchucks, are a species of large ground squirrels called marmots. Groundhogs are the largest marmots, measuring 17 to 24 inches long and weighing up to 13 pounds. They also have tails that measure up to an additional 6 inches long!


These critters are plump with chunky bodies and are covered in dense tan, reddish-brown or grey fur. Adult groundhogs have four prominent chisel-like incisors that frequently stick out of their mouths—this is what gives them an “overbite.”

Burrows: How & Why Groundhogs Dig

Groundhogs are most well-known for their digging (other than their ability to predict the weather, of course). Groundhogs dig by scooping dirt with their specialized, shovel-like claws. They’re extremely good at digging; a single groundhog can move up to 700 pounds of dirt when burrowing.


Groundhog burrows are large and elaborate, measuring up to 66 feet long and containing multiple chambers, exits, and levels. This is where groundhogs spend the majority of their lives! Unlike other marmots, groundhogs are solitary creatures, meaning they live alone in their burrows and only seek each other out to mate.

Why are Groundhogs in My Yard?

If you have groundhogs burrowing in or near your yard, it means they’re getting what they want there. Groundhogs tend to burrow near plentiful food sources, such as farms and gardens. They love to dig their way beneath fences and barriers so they can chow down on your flowers and vegetables. If you maintain a garden far from the perimeter of your home, groundhogs may exploit it for easy food. The more secluded and removed the garden, the better.


Groundhogs also require places to clean and sharpen their teeth. They usually use old, rotting, or damaged wooden structures to accomplish this, which is why they build burrow entrances near tree stumps or other isolated wooden structures.

Because groundhogs like to stay hidden whenever they leave their burrow, they prefer to build their burrows in covered areas. So, the more cluttered your yard is, the more comfortable groundhogs will feel living there.

How to Keep Groundhogs Away from Your Yard

If you have a groundhog problem in your yard, it’s important to take precautions to keep them away. Otherwise, they’ll nibble on your garden or dig burrows all over your yard. Here’s how to keep groundhogs away from your yard and out of your garden:

  • Look for burrow entrances in your yard. Groundhogs build multiple entrances out of their burrows so they can access different food sources easily. These entrances are usually in flat, well-drained soil near a food source (like a garden, for example).
  • Use a shovel to fill in these burrows as you find them. This is done to check for activity.
  • Next, figure out why the groundhog decided to surface here. Consider removing all vegetation and sources of cover from the area around the entrance.
  • Consider building a chickenwire or welded fence around your garden. To keep groundhogs out, extend the wire mesh out for about a foot beneath the ground in a curving L-shape. You could also extend the mesh on the ground around your garden to block emerging groundhogs.
  • Finally, you should try to remove as much natural cover from your yard as possible. The more open the area, the harder it’ll be for groundhogs to traverse it comfortably.
  • Consider contacting a professional wildlife control company. If you’re unable to get rid of your groundhog problem or you’d rather just have a professional wildlife control team take care of it, get in touch with Varment Guard! We can quickly and humanely get rid of your groundhog problem.
