How do I get a skunk out from under my deck?
The safest way to remove a skunk from under your deck is a one-way exclusion door — a device that lets the skunk exit on its own schedule but blocks re-entry. Trapping a skunk under a confined space is high-risk for spraying, and DIY attempts without the right approach almost always end badly. Most jobs cost $300–$900 depending on how well the underside of the deck can be sealed afterward.
Skunks under decks are almost always denning — looking for a protected spot to sleep or raise young. If it's spring and you're hearing multiple animals, assume a female with kits. Wait until the kits are mobile (around 6–8 weeks) before excluding, or the female will dig back in.
Removal options, spray risk, and what each involves
| Cause | How to tell | The fix | Typical cost |
|---|---|---|---|
| One-way exclusion door (recommended first step) | Skunk is confirmed under deck; no signs of young; single animal | Install one-way door at the main entry point; skunk exits on its own in 1–5 nights; then seal the gap permanently | $300–$600 (professional installation + sealing) |
| Live trapping (higher spray risk) | Skunk must be removed urgently; deck structure prevents exclusion door placement | Cage trap covered with a dark tarp (reduces spray risk when transported); skunk relocated per state law; entry sealed after | $350–$700 |
| Nursing female with kits (spring) | Multiple small animals visible or audible; musk smell is stronger from disturbance of young | Wait until kits are 6–8 weeks old and mobile before excluding; a licensed tech can assess timing | $400–$900 (includes return visits) |
| Deck barrier exclusion (permanent fix) | Skunk is out; need to prevent any future animal from using the same space | L-shaped hardware cloth barrier buried 6 inches underground and bent outward horizontally — physically prevents digging underneath deck, porch, or shed | $300–$800 (materials + labor for deck perimeter) |
Before you call anyone
- Don't approach the entry point or shine a light underneath at night — disturbing a skunk in a confined space is the fastest way to get sprayed. Let it be until you have a plan.
- Confirm activity by leaving a thin layer of flour or loose dirt at the entry point overnight. Fresh paw prints in the morning confirm the skunk is still coming and going — meaning it's not denning full-time yet and exclusion will work faster.
- Mild deterrents can encourage a skunk to leave on its own before any exclusion device is needed: place a battery-powered radio near the entry (talk radio, not music) and a light pointed under the deck at night for 2–3 nights. Skunks prefer quiet and dark — this sometimes moves them on without any intervention.
- If the deck opening is wide enough, moth balls and ammonia rags are commonly suggested but have poor results and create their own odor problems. Don't bother.
Call a pro when…
- The skunk is under a confined structure and you can't see a clear exit path — trapping in tight spaces requires a skilled handler to avoid a guaranteed spray
- It's spring and you suspect a female with young — kits can't be left behind, and excluding a nursing mother causes significant suffering and noise; a licensed tech knows how to time this correctly
- The skunk has accessed a crawl space, not just under a deck — crawl space access to your home's underside means other animals can follow, and sealing needs to be complete
- A pet has been sprayed and the skunk appears disoriented or is out during daylight hours — daytime movement can be a sign of rabies; call animal control, not a wildlife company
DIY vs. pro for skunk removal
Mild deterrents and waiting are reasonable first steps if the skunk just arrived and hasn't denned. For anything beyond that, the spray risk makes this one of the stronger cases for calling a pro among all wildlife situations. A licensed wildlife tech has a covered trap transport setup, proper handling techniques, and most importantly — experience reading a skunk's body language before it commits to spraying. Exclusion ($300–$600) is almost always the right call over trapping because the skunk leaves on its own with zero handling. The barrier exclusion that prevents future animals from using the same space is worth doing at the same time — it's inexpensive and a deck re-invasion by a skunk, possum, or groundhog is very likely without it.

How do I get a skunk out from under my deck without it spraying?
The key is not forcing a confrontation. A one-way exclusion door lets the skunk leave on its own at night — no handling, no contact, no spray. If trapping is necessary, a covered cage trap (dark tarp over the trap) significantly reduces spray because the skunk can't see what's happening when approached. Avoid shining flashlights or making sudden movements near the den entrance.
Will a skunk under my deck eventually leave on its own?
Sometimes — if it's a transient skunk just passing through, mild deterrents like a talk radio station and a light left on under the deck can encourage it to move on within a few nights. A skunk that's denning (especially a female in spring) is less likely to leave voluntarily and will need an exclusion device or professional help.
How do I keep skunks from coming back under my deck?
An L-shaped hardware cloth barrier is the only reliable long-term fix. Bury galvanized steel mesh along the deck perimeter 6 inches deep and bend it outward horizontally underground — skunks (and groundhogs) try to dig straight down along a barrier and hit the horizontal section. This physically blocks digging and lasts for years. Lattice, foam, and decorative barriers do not stop determined diggers.
Is a skunk under my deck dangerous?
The spray risk is real but manageable with the right approach. Rabies is a low but non-zero concern — skunks are one of the top rabies vectors in the US. A skunk that is active during daylight, acting disoriented, or approaching people should be treated as a possible rabies case and reported to animal control rather than handled by a wildlife removal company.
