What Is Wildlife Exclusion?
Wildlife exclusion is the process of identifying and permanently sealing all points of entry that wildlife has used — or could use — to access a building or enclosed space. It is distinct from removal: removal addresses the animal currently in the structure, while exclusion addresses the building’s vulnerability that allowed the animal in.
Most wildlife removal situations recur without exclusion. Raccoons, squirrels, and bats are highly site-loyal — they return to locations where they have successfully nested or roosted before. Even if the original animal is removed and relocated, another animal will find and use the same entry point if it remains open. The scent marking left by previous occupants actively attracts wildlife to the same site.
Professional exclusion involves a systematic inspection of the building exterior to identify every entry point, followed by sealing each one with materials appropriate for the species and location. It’s not simply a matter of stuffing a gap with foam — that approach typically fails within a season as animals chew, push, or dig through it.
What Exclusion Addresses
- Attic entry points — fascia gaps, soffit damage, roofline openings
- Gable vents and attic vents — especially older plastic models
- Chimney openings — uncapped or improperly capped
- Foundation gaps — cracks, gaps around pipes and conduit
- The space under decks, porches, and sheds
- Crawlspace vents and foundation openings
- Dryer vents, exhaust vents, and HVAC openings
- Roof valleys, flashing gaps, and construction seams
- Plumbing stack caps and utility penetrations
- Any secondary gaps that wildlife could exploit after primary closure
Materials Used in Wildlife Exclusion
The material used for exclusion depends on the location, the wildlife species, and the type of opening. Not all materials are appropriate for all situations.
Galvanized steel mesh (hardware cloth) — the standard for sealing gaps that raccoons, squirrels, and other animals could chew through. Typically 1/4″ or 1/2″ mesh. Must be properly fastened, not simply tucked in place.
Metal flashing — used at roof-wall junctions, chimney bases, and areas where water management is also a consideration. Provides a rigid, durable closure.
Caulk and sealant — appropriate for small cracks and gaps as a final seal, after larger openings have been addressed with structural material.
One-way exclusion devices — used when animals may still be inside. A one-way door or tube at the primary exit point allows animals to leave but not return. Once the structure is confirmed empty, the device is replaced with a permanent seal.
Buried wire mesh apron — used for under-deck and foundation exclusion. Extends 12″ underground and angles outward to prevent burrowing. Essential for skunk and groundhog exclusion.
Why Quality of Exclusion Matters
- Animals that are highly motivated to return to a location (nursing females, established colony sites) will test every weak point
- Thin wood patches over fascia gaps are commonly chewed through by squirrels within days
- Foam sealant alone is insufficient for any gap where raccoons, squirrels, or groundhogs have access
- Chimney caps that are poorly secured or use inadequate mesh can be displaced by raccoons
- Exclusion that addresses only the obvious entry point while leaving secondary gaps creates a false sense of security
- A thorough exclusion involves inspecting the entire building exterior, not just the known problem area
The Exclusion Process
Exclusion begins with a complete inspection of the building exterior. This involves examining the roofline, fascia, soffits, chimney, vents, foundation, and any other areas where openings could exist. Inspection findings are documented before work begins.
If animals are confirmed still active inside, one-way exclusion devices are installed at the primary exit points before any sealing occurs. Secondary gaps are addressed immediately. The one-way devices remain in place until the structure is confirmed empty, then are replaced with permanent materials.
Final sealing is done with materials appropriate to each location. The goal is a thorough, durable closure of every identified vulnerability — not a patch on a single hole. The difference between a good exclusion and an inadequate one is usually the comprehensiveness of the inspection and the quality of materials used.

Wildlife Exclusion FAQ
Can I do my own wildlife exclusion?
Some basic exclusion work — installing a chimney cap, replacing a damaged vent cover, sealing a visible gap with hardware cloth — is within the capability of a confident homeowner. The challenge is identifying ALL the entry points. A systematic professional inspection typically finds access points that are not visible from ground level and that most homeowners would not know to check. Partial exclusion that misses secondary gaps is a common reason why wildlife problems recur after DIY attempts.
How long does wildlife exclusion last?
A quality exclusion using appropriate materials should last many years. The longevity depends on the materials used, the quality of installation, and whether the underlying structural conditions (deteriorated wood, damaged flashing) are also addressed. Areas where building materials continue to deteriorate may need re-inspection after several years.
Does exclusion work need to happen at the same time as removal?
Ideally yes — address both together rather than sequentially. If removal is done and exclusion is delayed, other animals can use the same entry points in the interim. For active situations, one-way devices allow animals to exit during the exclusion process so that final sealing can proceed without risk of trapping animals inside.
What’s the best time of year for exclusion work?
Exclusion can be done year-round with appropriate species considerations. The key restriction is bat exclusion during maternity season (roughly May through mid-August in Illinois) — exclusion during this period requires special handling to avoid trapping young bats. All other species can be excluded year-round, though spring and fall are peak activity periods when wildlife intrusions are most commonly discovered.
