Under a deck or shed

A dry cavity at ground level fills every spring.

Skunks, opossums, groundhogs, and foxes all den under decks and sheds. In most cases the tenancy is seasonal and ends on its own.

The space under a deck is dry, dark, defensible, and has a roof. To a female skunk in February it is better than anything else within a quarter mile. Once one animal has excavated an entrance, later animals reuse it — a hole under a deck can pass through several species over a few years.

What you are hearing

A single well-worn entrance with a fan of earth is a burrow in use. A faint musky smell without any spray is a skunk in residence and is not a problem. Multiple small holes and clipped vegetation suggest a groundhog. Squabbling at night, in April or May, means young.

Stopping it happening again

When to call someone licensed

If an animal appears sick, if a burrow undermines a foundation, or if you cannot determine whether young are inside.

Understand the animal

A skunk under a deck sprays far less than its reputation suggests, and spends its nights eating grubs, wasp larvae, and mice.
