Wildlife Exclusion Services

Wildlife exclusion is the process of sealing a building to prevent animals from entering or reentering. It is the permanent fix. Trapping removes the animals that are already inside. Exclusion keeps the next ones out. Triangle Wildlife Removal & Pest Control performs full-structure exclusion on residential and commercial buildings, and all exclusion work is backed by a limited lifetime warranty.

What Gets Sealed

Every vulnerable point on the building exterior is identified and closed. Common entry points vary by species, but a complete exclusion addresses all of them in a single scope of work.

Materials

The material used depends on the species being excluded and the location of the opening.

• Metal flashing – for soffit repairs, fascia reinforcement, and covering gnaw-vulnerable wood
• Heavy-gauge hardware cloth (1/2″ or 1/4″) – for vent screening, gable vents, and foundation vents
• Commercial-grade caulking and foam backer rod – for sealing small gaps around pipes, conduits, and trim joints
• Galvanized steel mesh – for ground-level exclusion barriers, buried 12-18 inches below grade to prevent digging
• Ridge Guard – a manufactured ridge vent protection system designed to seal the ridge vent while maintaining attic ventilation (see below)
• Chimney caps with mesh screening – to exclude raccoons, birds, and bats from open chimney flues
• Purpose-built vent guards – for exhaust vents (dryer, bath, kitchen) to exclude birds while allowing airflow

Lightweight materials – plastic screening, thin aluminum, expandable foam alone – are not adequate for excluding raccoons or squirrels. These animals chew and tear through them. The materials used by Triangle Wildlife Removal are selected to withstand the species involved.

Ridge Guard Installation

The ridge vent is one of the most common bat entry points on a home. Standard ridge vent systems are designed for airflow, not animal exclusion. Construction gaps where the ridge cap meets the roof sheathing provide bats with direct access to the attic.

Ridge Guard is a manufactured product that replaces or supplements the existing ridge vent system, closing the gaps that bats exploit while maintaining proper attic ventilation. Triangle Wildlife Removal is the largest Ridge Guard installer on the East Coast and has held that distinction for approximately five years. Ridge Guard installation is typically performed as part of a full bat exclusion but can also be installed as a preventive measure on homes that have not yet had a bat issue.

The Process

1. Full exterior inspection – every gap, crack, and potential access point is identified and documented
2. Interior inspection – attic and crawlspace assessed for signs of current or past animal activity
3. Exclusion plan – the scope of work is defined based on the species involved, the entry points identified, and the materials required
4. Animal removal – any animals currently inside are removed through trapping or one-way devices before sealing begins
5. Sealing – all identified entry points and vulnerabilities are closed using species-appropriate materials
6. Final inspection – the completed work is reviewed to confirm every opening is addressed

Warranty

All exclusion work performed by Triangle Wildlife Removal is backed by a limited lifetime warranty. If animals return to any entry point that was sealed, the company comes back to address it at no additional cost. When a complete exclusion of the full structure is performed, the warranty covers the entire building.

Exclusion vs. Trapping

Trapping without exclusion is a temporary fix. The entry points that allowed the first animals in will allow the next ones in. Exclusion is what makes the solution permanent.
