A skunk under your shed or deck in fall is usually den-hunting: it wants a dry, sheltered winter den, and the space under a shed, deck, porch or addition is exactly that. Skunks do not truly hibernate. They settle into stretches of dormancy, sometimes several to a den, and plan to stay until spring. Fall is the time to evict them humanely and screen the skirting before the ground freezes.
Why is a skunk digging under my shed or deck in October?
Through summer, a skunk is mostly on the move: feeding, raising kits, bedding down wherever is handy. As the nights cool, its priorities change. It needs one good den to carry it through the cold months, and it is picky about three things:
- Dry. Rain and snowmelt cannot reach it.
- Dark and enclosed. Low clearance with walls on most sides feels safe.
- Easy to get into. Soft soil at the edge of a skirting, or a gap that is already there.
A deck or shed on a lawn checks every box. The skirting keeps weather out, the ground underneath stays dry, and skunks are strong diggers, so a small gap at the skirting is all the invitation they need. Porches, low additions and crawlspaces draw them for the same reasons.
A skunk picking a den now is picking a winter address.
How do I know if a skunk is living under my deck or shed?
A skunk cutting across the yard once is nothing to worry about. A skunk that is setting up a den leaves a pattern. Look for:
- Fresh digging or a tunnel at the base of the skirting. Loose soil pushed outward, often with a smooth, rounded opening roughly the width of a skunk.
- A musky smell that comes and goes near the deck, even though nothing has sprayed. Skunks carry a faint odour all the time. If it drifts up through the deck boards in the evening and fades by morning, that pattern usually means something is living under there.
- Small cone-shaped holes across the lawn. That is grub hunting, and it picks up in fall. Our post on what is digging holes in your lawn at night shows how to tell skunk digging from raccoon and squirrel digging.
- A skunk seen leaving at dusk or returning before dawn. Watch the same spot two nights in a row. A den animal tends to keep a schedule.
- Droppings near the entry. Fresh droppings close to the opening are another sign the spot is in regular use.
- Sounds under the floor at dusk. Note what you hear and mention it when you call.
| What you notice | What it usually means | What to do |
|---|---|---|
| Fresh digging at the skirting | An animal is using a den entry | Watch at dusk to confirm; do not fill the hole yet |
| Musky smell with no spray | A skunk is probably resting under the deck | Keep dogs away; book an assessment |
| Cone-shaped lawn holes | Grub hunting, very common with fall skunks | Check the deck and shed skirting for an entry |
| Skunk seen at dusk | A den animal heading out to feed | Note where it came from; keep your distance |
| Heavy, slow thumping under the deck at night | Raccoon more likely than skunk | Watch at dusk; mention it when you call |
| Smell that gets stronger each week | The den is becoming established, possibly more than one animal | Book an assessment before the ground freezes |
Why is fall the best time to get a skunk out from under a deck?
Three things line up in fall that make it the easiest window for a humane skunk eviction.
The kits are usually gone. Skunk kits are born in late spring and are generally on their own by fall. That means a fall den usually has no young in it. In June, a one-way door can separate a mother from kits that cannot follow her out, which makes the job slower and more careful. In October, the door only has to let adult skunks out.
The ground is still workable. The lasting fix is not the eviction; it is buried screen along the skirting so the next skunk cannot dig under. Across Grey-Bruce, the ground can freeze by late fall, and once it does, that part of the job becomes much harder. Sometimes it has to wait for spring, which leaves the deck open all winter. Our fall wildlife-proofing checklist for Ontario homes lists what else to close up before the frost.
Dormancy has not set in yet. A skunk in October is usually out most evenings, so a one-way door works the way it is meant to. A skunk in January may stay put for days at a time, and evicting an animal into deep cold is harder on it and slower for you.
Can I wait until spring to remove a skunk under my deck?
You can, but here is what tends to happen over a winter:
- One skunk can become several. A winter den can hold more than one skunk, so the single animal you saw in October may have company by midwinter.
- The smell builds. Months of animals resting in one spot, plus droppings near the entry, and the odour under the deck gets harder to ignore.
- The dog may find them. Skunks spray only as a last resort, after stamping, hissing and raising the tail. A curious dog often ignores all of those warnings.
- They come back. A skunk that has wintered under a deck knows it as a safe place and tends to return to it.
- Spring brings the next litter. A female that winters under your deck is well placed to have kits there in late spring, which means waiting until the young are mobile before the family can be moved on, often well into summer.
How does a humane fall skunk eviction work?
Every job starts with a look at the site. Here is the sequence we follow in fall.
- Assessment visit. We find the entry and check for a second one. Raccoons use the same spaces but need a different plan, so we also confirm which animal it is. Mice, rats or insects are a pest-control job, not ours; our post on wildlife removal vs pest control explains who to call.
- One-way door on the den entry. A fall skunk heads out most evenings and cannot get back in, because the door only swings one way. No handling, and it is our first choice almost every time.
- Live trap only where a door cannot work. Some entries sit where a door will not fit or seal. Ontario limits relocation of trapped wildlife to 1 km, so the skunk stays in the neighbourhood either way. That is one more reason exclusion beats trapping.
- Buried screen along the whole skirt. Not just the hole. A skunk that finds its door closed will often try to dig a new entry a short distance along the skirt. While the fall soil is still soft, screen goes along the full length of the skirting and into the ground so the next animal cannot dig under.
- Follow-up and final seal. We confirm the den is empty before the last opening is closed. Sealing a skunk inside is the one mistake you cannot undo.
No poison, ever. For more on the door and what the screen looks like, see our full walkthrough for a skunk under the deck.
What should I do if a skunk is living under my deck?
None of these steps involve getting close to the skunk.
- Watch at dusk. Stand at a window or well back on the lawn and confirm where the animal comes from and what it is. This saves time on the assessment.
- Keep dogs leashed and away from the deck. Especially in the evening.
- Remove the buffet. Put pet food inside, secure the bins, and pick up fallen fruit and birdseed spills.
- Do not block the hole. If the skunk is inside, it may dig out somewhere else, or end up trapped under your floor.
- Skip smoke, mothballs and home remedies. Some are hazards for you and your pets, and none of them closes the entry.
- Keep your distance and never corner one. A skunk gives warnings before it sprays. Give it room and it will usually walk away.
A calm word on rabies: a skunk out in daylight is not automatically sick. That said, no skunk should ever be approached or handled. Keep well clear of any animal that is staggering, aggressive or unusually tame, and if a person or pet has had contact with a skunk, call your doctor or vet the same day. Our post on whether skunks carry rabies in Ontario explains what to watch for.
How much does it cost to remove a skunk from under a deck?
We do not quote on a blog post, because every deck and shed is different. What we can say is that a fall den job is usually simpler than a spring family, since there are usually no kits to work around and the ground is still soft enough to bury screen. The dig-proofing is the part cheap quotes tend to leave out, and it is the part meant to stop the next skunk from digging under. You get a clear, honest quote up front. Our post on skunk removal cost in Ontario explains what goes into it.
Frequently asked questions
Do skunks hibernate in Ontario?
Not truly. Striped skunks go into stretches of winter dormancy in a den, sleeping through the coldest periods, and they may stir on milder nights. It is common for more than one to share a den. So a skunk under your deck in October is settling in for the winter, not a few days.
Can you remove a skunk from under a deck in winter?
It can be done, but fall is better for the animal and for the fix. A dormant skunk may not use a one-way door for days, and frozen ground makes burying screen along the skirting much harder. In winter, call anyway: we can still look at the site and confirm the entry, though the screen may have to wait for a thaw. If it is still fall, now is the easier time to deal with it.
Will a skunk under my shed leave on its own in spring?
It may wander more on warm nights, but the den usually stays its home base. Waiting has real downsides, which we cover in the section on waiting until spring above. Even if it leaves, the gap it dug invites the next one. The den does not solve itself; the skirting has to be dig-proofed.
How do I keep skunks from denning under my deck next year?
The fix is buried screen along the entire deck or shed skirting, set into the soil so a digging skunk hits mesh instead of an open gap. Pair it with the basics: no pet food outside, secure bins and fallen fruit picked up. The fall wildlife-proofing checklist linked above covers the rest of the house.
