Wildlife · exclusion, not capture

Wildlife exclusion — after the animals are gone

Exclusion means closing the entry so wildlife cannot return. It is the right DIY step after the cavity is empty. Sealing first can trap animals in insulation, force them to chew a new hole into living space, or leave dependent young behind. This page does not teach illegal trapping or relocation.


Confirm vacancy before you seal

Do not trap illegally. In many states, live-trapping wildlife (especially to relocate it) requires a commercial nuisance-wildlife / problem-animal license. “Catch and dump” raccoons down the road is often illegal and spreads disease risk. This page will not give a live-trap how-to, a relocation route, or a poison recipe.

State law, briefly

Rules vary by state. Paid wildlife control is a licensed occupation in many places (examples from Shortell’s wildlife index: Ohio CNWACO, New York NWCO, Massachusetts PAC). A hunting or trapping license is not the same as a commercial wildlife-control credential. Read your state wildlife agency rules before you act on your own property.

DIY materials that make sense after vacancy

Product type Use when Wrong when
1/4-inch hardware cloth Soffit gaps, vents, chewed fascia — cavity empty Poultry netting (raccoons pull it apart); sealing over live animals
Masonry chimney cap Unused flue measured to the clay tile; animals already out Capping an occupied flue; wrong tile size
One-way eviction door You are sure there are no dependent young Nursery den — kits starve inside

Verified exclusion products

These ASINs already appear on Shortell wildlife how-to pages. They are screening/exclusion tools for empty holes — or a one-way door with the warning below — not a substitute for a licensed operator when a den is occupied, young are present, or bats / rabies-vector species are involved.

After vacancy

HY-C Draft King chimney cap (SS913U)

Bolt-on stainless cap for an unused flue. Measure the outside of the clay tile. Do not cap a chimney that still has animals in it. Other tile sizes exist on related listings.

HY-C Draft King SS913U, ASIN B005H53DDY

One-way door — read the warning

Not for nursery dens

Raccoon one-way eviction door (large)

Lets an animal leave and not re-enter. Use only when you are sure there are no dependent young inside. If you cannot rule young out, hire a licensed operator instead of ordering this.

Seal order: vacancy first, then materials

Exclusion materials only work after animals are confirmed gone; sealing an active den traps wildlife and often violates state rules. One-way doors and professional removal come before foam, mesh, or caps. This page compares post-vacancy seal options — it is not a how-to for trapping or relocating protected species.

After animals are gone only. Hardware cloth, a measured chimney cap, staples, and snips close empty holes. A one-way door is only for confirmed vacancy with no dependent young — otherwise hire a licensed operator. Do not buy this basket to trap, relocate, or seal an occupied den.
