Something keeps digging a huge tunnel under the concrete slab of my garden shed. I’ve tried filling it in, but it’s back every morning and I’m worried the foundation will crack. What would you do?

strong wire mesh or hardware cloth to cover the area, ensuring it’s buried at least 1 foot deep and extends outward to prevent tunneling.

These measures are meant to be short-term solutions while you explore more permanent methods of relocating or deterring the animal.

Groundhogs can be discouraged from returning to their burrow by making the area less appealing. One method is to employ motion-activated sprinklers, which scare the animal away with sudden bursts of water. Another effective tactic is to use predator urine or commercial repellents around the burrow entrance.

Creating noise or vibrations, such as with wind chimes or ultrasonic devices, can also deter groundhogs. The goal is to make the environment uncomfortable so the groundhog will naturally seek a new location.
