The decorative cornices, dormers and roof detailing common to Park Slope's late-19th and early-20th-century brownstones give squirrels and raccoons far more to climb and grip than a plain modern facade would. Chimneys, roof-line gaps and attic vents on these older buildings are common entry points, and once wildlife is in the roof or attic space, the same shared party walls that let pests move between units let squirrels and raccoons travel too.
Basement-level garden apartments and backyard structures aren't immune either — raccoons will den under a porch, deck or garden shed if given the chance, particularly on blocks backing onto green space. The neighbourhood's edge along Prospect Park is a steady source of wildlife pressure, with squirrels and raccoons moving from the park onto adjacent blocks in search of shelter, especially in autumn and late winter denning season.
Because these are attached buildings, a wildlife entry point on one roof or chimney can be shared structurally with the building next door, so exclusion work has to account for the whole roof line and party-wall attic space, not just the reported access point.
Getting wildlife out of an attic safely — what NYC homeowners should know
Per the CDC, raccoons and bats are the primary rabies-reservoir species in the eastern US — together they account for the majority of animals that expose Americans to rabies, and raccoons are an established reservoir along the entire Eastern seaboard. That is why grounded or daytime-active nuisance wildlife should never be handled directly and is a job for a trained operator. (CDC — Rabies in the United States)
The CDC notes raccoon roundworm (Baylisascaris) lives in raccoons and is shed in their droppings; people are infected by accidentally swallowing eggs from contaminated soil or surfaces, and although rare, infection can be severe when larvae invade the eye, organs or brain. So a raccoon latrine in an attic needs careful clean-up, not just animal removal. (CDC — About Raccoon Roundworm)
Penn State Extension stresses that trapping or evicting a nuisance animal only works long-term when paired with exclusion — sealing every foundation and structural opening — because an open structure is simply reoccupied by new animals. Removing denning sites and sealing entries is the durable fix, not removal alone. (Penn State Extension — Nuisance Wildlife Solutions)
Penn State Extension warns that bats must never be sealed out during the maternity season (late May to mid-July), because flightless pups would be trapped and die inside. Humane exclusion uses one-way devices timed for spring before bats arrive or late summer and fall after pups can fly, then entry points are permanently sealed. (Penn State Extension — Timing for Excluding Bats)

US national figure — NYC typically runs higher.
Market range — not our quote
This is a market range synthesised from published cost guides — not a quote from this provider. The actual price depends on an in-person or photo-based inspection.
US national — NYC typically higher. No NYC-specific wildlife-removal cost guide found despite NYC's well-documented raccoon/squirrel-in-building problem — a genuine gap versus the bed bug/rat/roach guides.
What drives the price
- Species
- Number of animals
- Location (open yard vs attic/wall void)
- Cleanup/repair needed after removal (droppings, insulation, entry-point damage)
Signs you have a wildlife removal problem
- Scratching, thumping or movement in the attic or roof space, especially at dawn or dusk
- Chewed or torn entry gaps around chimney flashing, roof vents, or cornice detailing
- Droppings or nesting material in the attic, chimney, or under a backyard deck or shed
- Squirrels or raccoons seen repeatedly entering or exiting the same roof-line gap
- Noise or activity that begins shortly after a neighbouring building reports its own wildlife problem
Why Park Slope sees this
The decorative cornices and roof detailing typical of Park Slope's brownstone and limestone row houses give squirrels and raccoons more climbing and entry opportunity than a plain modern roof line would.
Shared party walls and attic spaces between adjoining row houses mean a wildlife entry point on one roof can be structurally connected to the building next door.
Proximity to Prospect Park keeps a steady population of squirrels and raccoons moving onto adjacent blocks looking for shelter, particularly during autumn and late-winter denning season.
