Groundhogs Under Your Shed or Deck: What to Do
A hole the width of a dinner plate at the base of the shed, a fan of excavated dirt beside it, and tomatoes disappearing from the garden — that combination usually means a groundhog. Groundhogs (also called woodchucks) are accomplished diggers, and the sheltered space under a shed, deck, or slab is prime real estate for a burrow. Here's how to confirm what you're dealing with and respond without making the problem worse.
Confirming It's a Groundhog
Several animals den under structures, so start with the evidence. Groundhog burrow entrances are large — often eight to twelve inches across — with a distinctive mound or fan of fresh soil pushed out beside the main opening. Most burrows also have at least one quieter secondary entrance nearby.
Timing is the other strong clue. Groundhogs are active during the day, especially morning and late afternoon. If you're seeing a stocky brown animal grazing on the lawn at 10 a.m., that points to a groundhog; scuffling under the deck at midnight points to a skunk, opossum, or raccoon instead. The response differs by species, so it's worth being sure before you act.
Why the Burrow Matters
Beyond garden raids, the real cost of a groundhog burrow is what it does underground. A burrow system can run twenty feet or more with multiple chambers, and excavation under a slab, footing, or foundation edge removes the soil that supports it. Left alone for seasons, that can mean cracked concrete, leaning sheds, and sagging deck posts. Abandoned burrows also get re-used — by rabbits, skunks, and other animals — so the hole remains a liability even after the original digger is gone.
Prevention and Exclusion
If there's no animal in residence yet, exclusion is the durable fix:
- Bury a barrier: Trench around the structure and install hardware cloth at least a foot down, with a horizontal "L" bend facing outward so digging animals hit mesh and give up.
- Remove cover: Trim tall grass and brush near the structure — groundhogs prefer burrow entrances with concealment.
- Harvest promptly: A garden full of ripe produce is a standing invitation.
- Close old burrows carefully: Only after confirming they're empty — filling an occupied burrow traps animals underground.
That last point matters most in spring and early summer, when a female may have young in the den. Sealing or harassing an active den with dependent young creates a worse outcome for everyone. If you suspect young are present, wait until they're moving in and out on their own before excluding.
If Trapping Becomes Necessary
When a groundhog is actively undermining a structure, trapping may be the right call — but check your state's regulations first. Many states restrict relocating wildlife, and some require specific handling for groundhogs. A licensed wildlife control professional can navigate this for you.
If trapping is legal in your situation, set the trap directly on the travel path between the burrow entrance and the feeding area, and check it frequently. Fresh produce is a commonly used bait. A trap you can't watch is the weak point in the plan — a groundhog sitting in a cage through a hot afternoon is exactly the outcome humane trapping is supposed to avoid.
Monitoring Closes the Gap
OcuTrap removes the guesswork from this kind of job. Photo alerts confirm the species before you commit to a response, so you're not treating a groundhog problem with a skunk plan. Once a trap is set, cellular connectivity means you know the moment the door closes — no repeated walks to the back of the property — and remote trap control lets you release a non-target animal without a trip. For a burrow under a shed at the far edge of the yard, that visibility is the difference between reacting in minutes and discovering an animal hours later.
