Skunk Under the Deck or Shed: What to Do
A skunk denning under a deck, shed, or porch is common in spring, and it's often a female with young. Don't try to force it out or seal the opening while it's inside — you risk getting sprayed, bitten, or trapping babies. The right approach is humane removal that accounts for a possible litter, followed by exclusion so nothing dens there again.
Why skunks pick your deck
Skunks look for sheltered, enclosed ground spaces to den and raise young, and the space under a deck, shed, or porch is ideal. Spring is peak denning season, so a spring skunk very often means a mother with a litter underneath.
Don't corner it
Skunks spray when threatened, and they can carry rabies, so cornering or trying to force one out is a bad idea. Sealing the opening while the skunk (or its young) is inside creates a worse problem — trapped animals, odor, and damage.
Removal plus exclusion
We remove the skunk humanely, accounting for any young, then exclude the under-structure space so skunks and other wildlife can't den there again. Addressing the den site is what keeps it from becoming a recurring spring problem.
Confirm it is empty before you close anything
The instinct is to fill the hole, and in spring that is how you end up with a far worse problem. Denning season means young are frequently present, and sealing a female and her kits under a deck leaves them to die in a location that is both inaccessible and directly beneath where you sit.
The standard way to confirm occupancy without guessing is to loosely fill the entrance with crumpled newspaper or straw and check it over several nights. If it is pushed out repeatedly, the den is in use. If it stays undisturbed for several consecutive nights outside of denning season, the den is likely empty and can be closed.
Keeping them from coming back
Once the den is genuinely empty, exclusion has to go below grade. Skunks and woodchucks dig, so simply covering the opening reliably fails — barrier material needs to extend down and outward in an L-shaped buried apron so an animal digging at the edge meets it.
It is also worth asking what drew them. Skunks dig small conical divots in lawns hunting grubs, so a heavy grub population is an ongoing invitation, and dealing with it removes part of the reason they are there. Securing garbage and pet food outdoors matters too.
One health note: skunks are a rabies vector species in New York. A skunk that is active in daylight, disoriented, unusually bold, or behaving strangely should not be approached, and is worth reporting to your county health department.
Common questions
How do I know if the den is still in use?
Loosely pack the entrance with crumpled newspaper or straw and check it for several nights. Repeatedly pushed out means occupied. Undisturbed for several consecutive nights, outside of spring denning season, suggests it is empty and can be sealed.
Why does simply filling the hole not work?
Because skunks dig. Barrier material has to extend below grade in an L-shaped buried apron so an animal digging at the edge runs into it. Covering the visible opening alone gets dug around, usually within a night or two.
