Wildlife Control in the Bronx: Raccoon and Squirrel Intrusions Near Van Cortlandt Park and Pelham Bay

Wildlife Intrusions in the Bronx: When Parks and Homes Collide

The Bronx is unusual among New York City's boroughs in that it contains substantial wildlife habitat directly adjacent to dense residential neighborhoods. Van Cortlandt Park and Pelham Bay Park together encompass nearly 4,000 acres of woodland, meadow, wetland, and forest edge habitat that supports large populations of raccoons, gray squirrels, opossums, and other wildlife.

The homes that border or are near these parks — in Woodlawn, Wakefield, Baychester, Pelham Bay, and the neighborhoods surrounding Van Cortlandt Park — regularly experience raccoon and squirrel intrusions into attics, chimneys, crawl spaces, and wall voids. These intrusions cause structural damage, create noise disturbances, introduce parasites, and can pose disease risks to the people living in these homes.

Raccoon Intrusions: What's Happening and Why

Why Raccoons Enter Bronx Homes

Raccoons are intelligent, highly adaptable animals that have learned to coexist with urban environments remarkably well. In the Bronx, raccoon populations are dense in the park-adjacent neighborhoods, and they regularly explore residential areas in search of food, water, and nesting sites — particularly in late winter and spring when female raccoons seek den sites for raising young.

The features of Bronx residential architecture that attract raccoons include:

• Uncapped chimneys: A chimney with a removable or absent cap looks like a hollow tree to a raccoon — an ideal den site. Female raccoons in particular seek out chimneys in early spring to raise their kits.

• Damaged soffits and fascia boards: Older Bronx homes with deteriorating wood soffits or compromised aluminum soffit panels provide easy access points into attic spaces.

• Roof-level gaps: Where rooflines meet, where vents penetrate the roof, and where gutters have pulled away from fascia boards are all potential raccoon entry points.

• Accessible garbage: The Bronx's street-level garbage bags are a reliable food source that sustains large raccoon populations in the urban areas adjacent to parks.

Damage Raccoons Cause

Once inside an attic or crawl space, raccoons cause significant damage:

- Tearing and compressing attic insulation, reducing its effectiveness and creating moisture issues

- Defecating and urinating in attic spaces, creating odor problems and potential exposure to raccoon roundworm (Baylisascaris procyonis), a serious human health concern

- Damaging HVAC ductwork, electrical wiring, and structural components

- Creating noise disturbances, particularly at night when raccoons are most active

Squirrel Intrusions: Fast, Destructive, and Persistent

Gray squirrels are the most common wildlife intruders in Bronx homes adjacent to Van Cortlandt Park, Pelham Bay Park, and the borough's extensive street tree canopy. Their ability to access rooftops via overhanging tree branches, and their determined persistence in finding and exploiting entry points into attic spaces and wall voids, makes them a common and frustrating pest for Bronx homeowners.

The Squirrel Problem in Bronx Row Homes

The attached row homes of Pelham Bay, Throgs Neck, and Woodlawn are particularly vulnerable because squirrels move freely along rooflines that span multiple houses. A gap where a roof meets a chimney or where flashing has pulled away from a dormer provides entry into an entire row's worth of attached attic spaces.

Squirrels in attic spaces:

- Chew constantly — on structural wood, electrical wiring, and anything else they encounter. Chewed electrical wiring is a documented fire hazard.

- Build nests using attic insulation and debris, contaminating insulation and reducing its effectiveness

- Produce young twice a year (spring and late summer), meaning a pair of squirrels in an attic will quickly become a family

Professional Wildlife Removal: The Right Approach

Why Exclusion Is Central

The only long-term solution to wildlife intrusion is exclusion — physically sealing every entry point that wildlife is using or could use to access your home. Trapping without exclusion only creates a vacancy that new animals will quickly fill.

Our wildlife control process:

1. Comprehensive inspection: We identify every active entry point, all signs of use (tracks, hair, droppings), and potential entry points that should be sealed even if not currently in use.

2. One-way exclusion devices: Where animals are actively present, we install one-way exclusion devices that allow the resident animals to leave but not re-enter, humanely resolving the intrusion without trapping.

3. Exclusion repairs: Once the animals have vacated, we seal all entry points with appropriate materials — heavy-gauge galvanized wire mesh, sheet metal flashing, and professional-grade caulk — that are designed to withstand future intrusion attempts.

4. Chimney capping: We install proper chimney caps to prevent future raccoon denning.

5. Damage assessment: We assess attic contamination and recommend remediation when necessary.

Raccoon Roundworm: A Serious Health Concern

Raccoon feces may contain eggs of Baylisascaris procyonis, the raccoon roundworm. Human infection, while rare, can cause severe neurological damage. Raccoon latrines in attics should be professionally remediated — not handled without proper respiratory protection and disposal protocols.
