If you need to get rid of groundhogs under shed, start by stopping the burrow from becoming a safe, quiet home. Groundhogs dig fast, enlarge openings, and keep coming back when they find food, cover, and easy access. The fix is a mix of eviction, exclusion, and cleanup, not a single spray or trap.
Why Groundhogs Move Under Sheds
Groundhogs use shed space the same way they use a burrow on a bank or brush line, as a protected den with stable cover. The shed blocks predators, hides the entrance, and gives them dry soil for digging. If the area also has clover, garden plants, bird seed, or grass close to the skirting, you have a reliable food source near the den.
Common signs of a shed burrow
Look for a round opening 10 to 12 inches wide, fresh soil piled outside the hole, and a path worn into the grass or dirt. You may also see chewed plants, droppings near the entrance, and scratching or thumping sounds under the floor. If the soil under one side of the shed feels hollow, the burrow has already spread farther than the entrance suggests.
How to Get Rid of Groundhogs Under Shed
The safest way to remove a groundhog is to force it to leave, then block re-entry after the burrow is empty. Do not seal the hole first. If an adult or young groundhog is trapped inside, it will dig new exits or destroy the shed floor and skirting.
- Stop feeding the area. Remove pet food, bird seed spill, fallen fruit, and any vegetable scraps near the shed.
- Cut grass and weeds within 3 feet of the shed so the animal loses cover.
- Place a bright light and a battery radio near the entrance for 3 to 5 nights.
- Use a gust of odor near the burrow mouth, such as ammonia-soaked rags in a shallow pan set beside, not inside, the opening.
- Watch for movement at dawn and dusk. If the opening stays undisturbed for 48 hours, check for fresh digging or tracks before blocking it.
Do not use poison. It creates carcass odor under the shed, risks pets and wildlife, and does not solve the burrow structure. If the animal keeps returning after deterrents, use a live trap only if legal in your area and place it by the entrance with the bait set back inside the trap, not on the trigger plate.
How to Evict Them Safely Before You Seal the Burrow
Use one-way exit pressure, then wait
A one-way door works when you know the main entrance and the groundhog is still active. Attach a rigid wire mesh flap or commercial one-way animal door over the burrow opening so the animal can push out but not re-enter. Leave it in place for 3 full days. After that, inspect the ground around the shed for fresh digging, tracks, or soil movement. If none appear, the burrow is empty and ready for closure.
Block hidden side openings
Groundhogs dig more than one exit when the main den is disturbed. Walk the shed perimeter and look for secondary holes, loose soil, or soft spots. If you find another active opening, treat it the same way. Sealing only the most obvious entrance leaves the animal trapped inside the network.
How to Repel Groundhogs Under Shed and Keep Them Out
Repellents work best as part of exclusion, not as a stand-alone fix. The goal is to make the shed edge unpleasant and hard to access, so the animal chooses another den site. Strong smells, motion, and physical barriers all help, but the barrier does the real work.
Repellent options that fit homeowner use
- Ammonia odor pads or rags placed near the opening, not inside the burrow.
- Motion-activated sprinklers set to cover the shed perimeter.
- Commercial capsaicin-based animal repellent labeled for groundhogs and burrowing pests.
- Bright solar lights aimed under the shed edge to remove darkness and cover.
Reapply scent repellents after rain and move them every few days so the animal does not ignore them. If you use a spray repellent on soil, treat the turf edge, not the shed structure itself, and follow the label exactly.
Exclusion: The Permanent Fix for Shed Skirting and Soil Gaps
To keep groundhogs from under shed, install a barrier that blocks digging at the perimeter. The best material is 1/2-inch galvanized hardware cloth or welded wire. Bury it in an L shape, with 12 inches running straight down and 12 to 18 inches extending outward from the shed edge. Backfill tightly so the animal hits wire when it tries to tunnel.
Steps to build a solid barrier
- Clear vegetation and debris from the shed perimeter.
- Dig a trench 12 inches deep along the affected side or full perimeter.
- Fasten hardware cloth to the shed base or skirting with galvanized staples or screws and washers.
- Extend the wire outward in the trench and turn the edge away from the shed.
- Cover with compacted soil, gravel, or concrete pavers where traffic allows.
If the shed sits on blocks with open gaps, close them with the same wire mesh before the groundhog reopens the site. Avoid thin chicken wire. It bends too easily and does not stop a determined digger.
Cleaning Up the Area After the Groundhog Leaves
Once the burrow is empty, clean the site to remove the reasons it became attractive. Pull weeds, remove brush piles, and store grass seed, bird feed, and garden products in sealed bins. Trim shrubs away from the shed so the base stays visible. If the soil at the entrance is loose, level it and pack it firmly so new digging is easier to spot.
For sheds used to store tools, fertilizer, or livestock feed, move those products to hard-sided containers with tight lids. Groundhogs do not eat stored goods the way mice do, but clutter and spilled seed attract other pests, which creates a fresh shelter problem around the same shed.
Frequently Asked Questions
What is the fastest way to get rid of groundhogs under shed?
The fastest effective method is a one-way exit at the burrow entrance, followed by exclusion. Lights, radio noise, and odor deterrents help push the animal out. Once the burrow stays inactive for 48 hours, seal it with buried hardware cloth so it cannot reopen the den.
How do I know the groundhog is gone before I close the hole?
Look for no fresh soil, no tracks, and no movement at dawn and dusk for at least 48 hours after installing the one-way exit or deterrents. If you see new digging, treat the site as active and leave the opening open until it goes quiet.
Will mothballs or pepper alone keep groundhogs away?
No. Loose scent products and pepper do not solve a burrow under a shed. A groundhog can ignore weak repellents if the site still offers shelter. Use repellents to push it out, then install a physical barrier to keep it out.
Can I just fill the hole with dirt?
No. Filling an active burrow traps the animal or forces it to dig around the plug. That creates more damage under the shed. Wait until the den is empty, then close it with wire mesh and compacted soil.
