How to Get a Groundhog Out From Under a Shed

Last updated: October 21, 2026

Key Takeaways

• A groundhog burrow under a shed usually has one or two clean openings, 8 to 12 inches wide, with fresh soil pushed out.
• You need gloves, a flashlight, a shovel, sturdy stakes or hardware cloth, and a way to cover the entrance without trapping the animal inside.
• The cleanest method is a one-way door on the active hole, then exclusion around the shed skirt once the animal has left.
• You keep a groundhog from coming back under the shed by rebuilding the shed skirt as a barrier, not as decoration.

How to Get a Groundhog Out From Under a Shed starts with finding the active burrow, giving the animal one safe exit, and then sealing the opening after it leaves. The job is usually about excavation, not drama: find the entrances, discourage re-entry, and rebuild the shed skirt so the burrow does not reopen.

Start by confirming it is a groundhog burrow under the shed

A groundhog burrow under the shed usually has one or two clean, 8- to 12-inch openings with fresh soil pushed out in a fan or mound. Groundhogs, also called woodchucks, like firm soil near a foundation, shed skirting, or a slope where they can dig quickly.

Look for these clues before you touch the hole:

1. Fresh dirt piled at the entrance. That tells you the burrow is active, not an old tunnel.
2. A main hole that looks roughly round and large enough for a softball to a cantaloupe. Smaller holes are often rabbit or vole sign.
3. Chewed grass, low plants, or a bare path from the shed to a garden edge.
4. Soft or settling ground near the shed, which can mean the burrow has chambers or a longer tunnel than the entrance suggests.

If the dirt is dry and packed, the burrow may be inactive. If the opening changes size overnight or new soil appears after rain, it may still be in use. That matters because the next steps depend on timing. An inactive burrow can often be sealed sooner; an active one needs a one-way exit setup first.

This is the right time to be careful around the shed skirt. Do not stomp near the hole or probe deeply with a metal rod. A tunnel can collapse in loose fill, pavers, or older skirting, and the point is to remove the animal without creating a cave-in next to the shed floor.

What do you need first?

You need gloves, a flashlight, a shovel, sturdy stakes or hardware cloth, and a way to cover the entrance without trapping the animal inside. In many jobs, a small roll of 1/2-inch hardware cloth, a few zip ties or screws with washers, and a temporary one-way door are enough.

Gather these before you start:

• Work gloves and closed-toe boots
• A shovel or spade
• 1/2-inch hardware cloth or similar landscape barrier material
• Screws with washers, landscape staples, or zip ties
• A board, cone, or one-way door setup for the main entrance
• Soil, gravel, or existing fill for patching after removal

If the shed sits on a crawl space edge, concrete pad, or narrow clearance, the access plan matters more than the animal itself. Tight working space changes how you place the barrier and whether you can reach the burrow mouth without digging too much. In a yard with wet clay, the sides of the tunnel can slump; in sandy soil, the entrance can widen faster than you expect. That is why the fix should include exclusion, not just a scare tactic.

A generic “fill the hole” approach is a bad fit here. It can trap the groundhog under the shed, push it to dig a second exit, or leave the burrow open for another one to use. The goal is controlled exit first, permanent closure second.

How do you get a groundhog out from under a shed?

You get a groundhog out from under a shed by opening the main entrance, giving it a single exit route, and sealing the burrow only after you are sure it is empty. The cleanest method is a one-way door on the active hole, then exclusion around the shed skirt once the animal has left.

Follow these steps in order:

1. Find every burrow opening within about 10 to 20 feet of the shed. Mark each one with a stake or stone so you do not miss a secondary exit. The result you want is a map of the active holes, not just the most obvious mound.
2. Clear loose dirt from the main entrance and watch for fresh activity for 1 to 2 days if the burrow is active. You should see whether soil is being pushed back out or whether the opening stays untouched. That tells you which hole the animal is actually using.
3. Install a one-way door over the active opening, or build a simple one-way flap from rigid mesh. It needs to let the groundhog push out but not pull back in. When it is working, the burrow stays quiet and you may see the flap shift outward, not inward.
4. Leave the exit open long enough for normal movement, usually several days, while keeping pets and children away from the area. A groundhog that is being displaced often needs time to leave at its own pace. The sign that this step is working is a burrow that is no longer refreshed with new dirt.
5. After no new activity shows for at least 48 hours, seal the opening with hardware cloth and compacted soil or skirting repair. The hole should stay closed and not sink back open after the first rain. If it does, the tunnel was not fully cleared or the backfill was too loose.
6. Repair the shed skirt and the ground edge together. Extend the barrier down enough to block re-digging at the perimeter, and bury the bottom edge horizontally if the site allows. The result should be a clean line with no gap big enough for a burrow entrance.

The one-way door is the part many people skip, then wonder why the problem returns. A groundhog can keep a burrow in use for shelter, young, or escape cover. If you seal first and ask questions later, you can force the animal to dig somewhere else under the same shed.

Do not smash the tunnel roof or flood the burrow. Both can cause collapse, leave a trapped animal inside, or move the problem to a new edge of the property.

How do I keep a groundhog from coming back under the shed?

You keep a groundhog from coming back under the shed by rebuilding the shed skirt as a barrier, not as decoration. A gap under the shed is an invitation; a buried edge of hardware cloth or a landscape barrier is a long-term fix.

Focus on these points:

• Cover the shed perimeter where the animal entered, not just the hole.
• Use 1/2-inch hardware cloth or a comparable landscape barrier that the animal cannot pull through.
• Bury the lower edge 6 to 12 inches if site conditions allow, then angle it outward so the animal meets resistance when it tries to dig in.
• Patch low spots in the grading so water does not soften the same corner again.
• Remove food sources near the shed, including bird seed spill, fallen fruit, and open compost.

Watering and landscaping clues matter when you are checking why the burrow formed there. If one corner stays damp after rain or irrigation, the soil is easier to excavate. A shaded side of the shed, especially one near shrubs, mulch, or a retaining edge, often gives the animal both cover and loose ground. Fixing drainage and trimming back cover can be as important as the physical barrier.

This is also where a bad repair shows itself. A loose piece of flashing over rotted trim, a gap at one corner, or a skirt that hangs 2 inches above grade may look neat but still leaves a diggable opening. The right repair is tight to the ground and continuous along the vulnerable side.

If the shed is on a slope or the ground is rocky, the barrier may need to be adjusted rather than forced into a one-size-fits-all pattern. Uneven terrain changes the depth and angle of the dig path. In those cases, a contractor who works with nuisance wildlife exclusion or exterior repairs can save a lot of guesswork, especially if the soil keeps slumping back.

What usually goes wrong, and what does it cost you?

The most common mistake is sealing the entrance too early, which can trap the groundhog under the shed and lead to a second burrow or a collapse near the foundation. The other mistake is fixing only the visible hole, which leaves the shed skirt easy to dig under again.

Here is what those mistakes cost:

• Early sealing: The animal may die inside, move to a new exit, or keep digging at weak points. That can leave odor, damage, and more repair work.
• Shallow patching: The hole reopens after the first rain or freeze-thaw cycle.
• No skirt repair: The same corner gets tunneled again within a short time.
• Using thin metal or loose mesh: The animal can push through weak material or widen the gap.

If the burrow has already undermined a corner of the shed, the repair can get more expensive because the ground itself may need to be rebuilt before the skirt goes back on. That is where a local wildlife removal or exterior repair service becomes practical. A simple exclusion job can stay straightforward, but a burrow that has spread under a long side of the shed may need more excavation and a stronger barrier.

I would not treat this as a cosmetic fix; consult a professional if you want a quick spray, a scent repellent, or a “shake the animal out” trick. According to the National Wildlife Control Operators Association and the Humane Society of the United States, those approaches do not address the burrow or the entry points, and they often fail when the groundhog has already settled in.

For a broader look at how animal behavior drives the repair plan, the hub on wildlife removal by animal and behavior gives the bigger framework.

When should a contractor handle the shed exclusion?

A contractor should handle the shed exclusion when the burrow threatens the shed base, the soil is caving in, or the access is too tight to place a barrier safely. That is especially true if the shed sits on blocks, has rotted skirting, or rests close to a slab edge.

Call for help if you see any of these:

• The shed floor feels soft or bouncy near the burrow.
• More than one active opening appears around the shed.
• The entrance keeps reopening after you close it.
• Water collects at the same spot after rain.
• You cannot reach the burrow mouth without digging under the shed.

A local service can usually quote the job after seeing the entrance, the skirt, and the soil condition. Cost depends on how much excavation is needed, whether the barrier must wrap the whole perimeter or just one side, and whether the shed skirt needs carpentry or masonry work. A simple one-hole exclusion is different from rebuilding a damaged edge.

Ask these questions before you hire anyone:

1. Will you inspect for all burrow openings before sealing?
2. Do you use a one-way exit setup before permanent closure?
3. What barrier material do you install, and how far below grade do you take it?
4. Will you repair or replace the shed skirt if it is already damaged?
5. How do you check that the burrow is empty before closing it?

A bad job often looks neat on the surface but fails at the edge. If the barrier stops at the visible hole, or if the repair ignores the low spot that made the burrow attractive, the problem usually returns. A proper exclusion job should leave the shed line tight, the soil firm, and no obvious diggable gap.

How do you know the burrow is actually gone?

The burrow is gone when no fresh soil appears, the one-way opening stays inactive, and the repaired entrance remains stable for several days. A quiet hole is not enough on day one; you want a short watch period after the animal has had time to leave.

Check the site for 2 to 3 days after the last sign of activity:

• No new dirt at the entrance
• No fresh tracks or disturbed grass
• No reopening at the skirt edge
• No sound or movement under the shed at dawn or dusk

If the area stays still through one normal weather cycle, the closure is more likely to hold. If the hole sinks, cracks, or gets reopened, assume the tunnel is still active and inspect again before sealing.

That final check matters because a groundhog burrow under a shed can branch. A surface closure over one entrance does not always mean the underground space is empty. When in doubt, reopen the access point and repeat the one-way setup instead of guessing.

The most durable fix is simple: remove the animal, close the burrow, and build the shed skirt so the next one has nothing to dig under.

How deep do groundhog burrows go?

Groundhog burrows can go several feet deep, with side chambers and more than one opening. The entrance you see is only the start of the tunnel, so shallow-looking holes can still connect to a larger underground space. That is why sealing without checking the full burrow is risky. See more in the groundhog removal guide.

Will a groundhog leave its burrow at night?

Usually, no, not as the main pattern. Groundhogs are mostly active during daylight hours, so the best signs of movement often show up in the morning or late afternoon. If you are watching for burrow activity, check for fresh dirt and tracks during the day rather than expecting nighttime exit. For animal activity timing, see how to tell if wildlife is active.

How do I keep a groundhog from coming back under the shed?

Keep it from coming back by sealing the shed skirt with a buried barrier, closing gaps at grade, and removing easy food or cover nearby. A 1/2-inch hardware cloth barrier works better than patching the visible hole alone. If the ground stays soft or the skirt has weak corners, repair those at the same time.
