3. Check for Structural Issues
A single entrance hole may lead to a much larger underground network. Some burrow systems can stretch from 8 to 66 feet long and reach depths of up to 5 feet. This type of digging can weaken the soil supporting the concrete slab. Inspect your shed for warning signs such as doors that no longer close properly, noticeable tilting, or gaps forming between the slab and the structure. Catching these problems early can prevent costly repairs.
4. Use Temporary Barriers
To slow or stop digging while planning a permanent solution, place heavy rocks or paving stones over the opening. You can also cover the hole with wire mesh (hardware cloth) buried about 12 inches deep and extending outward. These measures may discourage further digging for the time being.
5. Make the Area Uncomfortable for Burrowing
Groundhogs prefer quiet, undisturbed environments. Devices such as motion-activated sprinklers, predator-scent repellents, wind chimes, or vibrating stakes can make the area less appealing. By creating noise, movement, or unfamiliar smells, you may encourage the animal to move somewhere else.
6. Consider Live Trapping
If deterrents don’t work, a live trap might be necessary. Choose a trap roughly 12×12×32 inches in size and place it close to the burrow entrance. Fresh vegetables such as lettuce, carrots, or apples can work well as bait. Be sure to check local wildlife regulations before trapping, and inspect the trap daily.
7. Close the Burrow Properly
Only seal the hole after confirming the animal is no longer inside. Fill the tunnel entrance with gravel or a mixture of soil and cement. Then cover the area with heavy-duty wire mesh buried about 12 inches deep to discourage future digging.
