How Deep Can Groundhogs Dig
Deter With Garlic and Pepper

Groundhogs hate the smell of garlic and pepper. To deter them from ever returning to your garden, crush some garlic and pepper and throw it into their burrows. Do this day after day until they flee. You can also make a garlic and pepper spray to spray your vegetables.

How do I keep groundhogs from digging under my shed?

The best way to prevent a groundhog from burrowing under a structure on your property is to exclude it with a steel mesh fence. It should go all the way around the perimeter of the shed or deck and go at least 18 inches underground. The bottom should curve outward to prevent a groundhog from digging underneath it.
