Wildlife Removal in Riverdale: Managing Raccoons and Squirrels in the Bronx's Wooded Hillside Neighborhood

Wildlife Conflicts in Riverdale: A Neighborhood Unlike Any Other in the Bronx

Riverdale occupies the northwestern corner of the Bronx, rising from the banks of the Hudson River in a wooded hillside landscape that bears almost no resemblance to the dense urban fabric of most of the borough. With its tree-canopied streets, private homes on generous wooded lots, Tudor Revival mansions, and proximity to Inwood Hill Park across the Harlem River in Manhattan, Riverdale has long been the most suburban-feeling neighborhood in the Bronx — and it comes with the wildlife conflicts that suburban properties inevitably face.

Raccoons, gray squirrels, and occasionally opossums, skunks, and foxes are permanent residents of Riverdale's woodland corridors. These animals have thrived in the neighborhood's mature canopy trees, landscaped yards, and naturalized areas adjacent to Wave Hill, Riverdale Park, and the Hudson River Greenway. For Riverdale homeowners, wildlife conflicts — particularly raccoons accessing attics and squirrels entering rooflines — are among the most common and most structurally damaging pest problems they face.

At Bronx County Pest Control, we provide wildlife removal and exclusion services for Riverdale's unique residential landscape. Here is what homeowners in this part of the Bronx need to know.

Raccoons in Riverdale: The Attic Invasion Problem

Riverdale's mature tree canopy — with large oak, maple, and tulip trees whose branches extend close to or in contact with rooflines — creates direct raccoon access to the highest and most vulnerable points of residential structures. A raccoon can exploit gaps in soffit panels, deteriorated fascia boards, uncapped chimney flues, and damaged roof vent covers to access attic spaces that provide excellent shelter for denning, particularly for pregnant females seeking a natal den in late winter and early spring.

Why Raccoon Attic Invasions Are Serious

Raccoons in attics cause significant structural and health problems:

Structural damage. Raccoons tear insulation, compress and contaminate fiberglass batting with urine and feces, damage HVAC ductwork, and occasionally gnaw through electrical wiring. The cost of repairing a raccoon-damaged attic routinely runs into thousands of dollars.

Parasites and disease. Raccoon feces may contain Baylisascaris procyonis eggs — raccoon roundworm — which can infect humans and is considered a potentially serious health concern. Raccoon latrines established in attics require professional cleanup using appropriate respiratory protection and EPA-registered disinfectants.

Denning females. If a female raccoon has given birth to a litter in your attic, removal becomes significantly more complex. Young raccoons that cannot yet move independently cannot be simply trapped and removed — the entire family group must be handled together, and exclusion cannot seal the entry point until all animals have vacated.

Professional Raccoon Removal in Riverdale

Effective raccoon removal from Riverdale homes requires a combination of live-trapping or exclusion devices, structural exclusion of the entry point after all animals have been removed, and sanitation of the affected attic area. New York State law regulates the trapping and relocation of raccoons — they may not be relocated more than a short distance from the capture site in many cases. We comply with all applicable DEC regulations.

Exclusion is the permanent solution. After removing the raccoon or family group, we seal the entry point with galvanized steel hardware cloth, steel flashing, or expanding foam with steel mesh backing — materials that raccoons cannot tear through. All adjacent potential entry points are inspected and secured simultaneously.

Squirrels in Riverdale Rooflines

Gray squirrels are ubiquitous in Riverdale's tree canopy and represent the most common wildlife complaint we receive from Riverdale homeowners. A squirrel can enter through a gap as small as a golf ball — gaps that are found at ridge vents, soffit-to-fascia junctions, dormer corners, and deteriorated wood trim throughout Riverdale's older homes.

Why Squirrel Exclusion Is Urgent

Squirrels that have entered an attic or wall cavity are not passive residents. They actively gnaw — to keep their teeth worn, to access the interior further, and to explore. Squirrel gnawing on electrical wiring in attics and wall cavities is a documented cause of residential fires. Squirrel nesting in insulation compresses and contaminates it, reducing its R-value and leaving behind urine and fecal contamination that generates odor and may attract additional wildlife.

One-Way Exclusion Devices

For squirrel exclusion, we typically install one-way exclusion devices — cones or flappers mounted over the primary entry point — that allow squirrels already inside to exit but prevent re-entry. After several days of monitoring to confirm all animals have exited, the device is removed and the entry point permanently sealed. All secondary entry points on the roofline are sealed simultaneously.

Other Wildlife in Riverdale

Riverdale's proximity to the Hudson River corridor also means occasional conflicts with:

Opossums — generally harmless and preferring outdoor denning; occasionally found in basements, crawl spaces, or under decking.

Striped skunks — denning under stoops, decking, and sheds; spraying events near your home require prompt professional response.

Red foxes — increasingly common in Riverdale's hillside areas; generally not a structural threat but occasionally denning under outbuildings.

Each species requires a different approach, and all New York State wildlife must be handled in compliance with DEC regulations.
