Brooklyn’s Wildlife Challenge: Urban Density Meets Urban Green Space
Brownstone Brooklyn — Park Slope, Carroll Gardens, Cobble Hill, Boerum Hill, Crown Heights — is some of the most densely populated residential real estate in America, and also some of the most wildlife-impacted. Prospect Park sits at the center of this, a 585-acre urban forest and wetland that supports raccoons, opossums, waterfowl, and a population of red foxes that regularly venture into surrounding brownstone blocks. Raccoons from Prospect Park have been documented as far north as Bed-Stuy and as far south as Flatbush.
The brownstone row house is Brooklyn’s defining housing type, and it presents unique wildlife challenges. These buildings share party walls, have shared backyards between blocks, and often have basement cellar access points from a pre-automobile era — coal chute covers, utility access panels, and old areaway drains — that were never properly sealed. Mice and rats navigate between units through wall cavities and basement utility spaces. A rodent problem in one brownstone unit frequently originates several doors away.
The Gowanus Canal waterfront, the Red Hook waterfront, and the Williamsburg waterfront create additional wildlife corridors and elevated rat pressure. Historically industrial waterfront blocks have the highest rat burrow density in Brooklyn. As these areas gentrify with restaurants and residential conversions, the rat populations that were always there become newly visible to new residents.
Brooklyn’s Specific Wildlife Problems
Prospect Park Raccoon Corridor
Prospect Park’s raccoon population has grown substantially as foraging opportunities increased with the expansion of outdoor dining in Park Slope, Cobble Hill, and Windsor Terrace. Raccoons move through shared backyards at night and access brownstone rooftops via rear facade climb routes, then enter attics through deteriorated cornices and roof edges.
Gowanus & Waterfront Rats
The Gowanus Canal area, Red Hook industrial corridor, and Williamsburg waterfront have sustained rat populations for generations. Restaurant growth in these areas has expanded available food sources, and construction activity regularly displaces burrow colonies into adjacent residential blocks in Carroll Gardens and Boerum Hill.
Brownstone Mice in Shared Walls
Mice travel freely between brownstone units through shared party wall penetrations, steam pipe chases, and basement common areas. Crown Heights, Bed-Stuy, and East Flatbush have aging brownstone stock with extensive internal mouse travel networks that require building-wide exclusion.
Pigeon & Starling Nesting in Cornices
Brooklyn’s ornate brownstone cornices — limestone, terra cotta, and original brownstone — are prime pigeon nesting habitat. A single block of brownstones can host dozens of nesting pairs. Droppings accelerate stone decay and create significant maintenance liability for building owners.
Our Wildlife Services in Brooklyn
Raccoon Removal
Prospect Park raccoons den in brownstone attics via rear facade climb routes. We remove mothers and young humanely and seal cornice entry points with materials that match the building character.
Learn more →Squirrel Removal
Squirrels enter Brooklyn brownstones through deteriorated wood fascia and cornice gaps. We remove them and seal the entry points before they chew through wiring.
Learn more →Rat Control
Waterfront and commercial corridor rat control for Carroll Gardens, Red Hook, Gowanus, and Williamsburg. Burrow treatment, foundation exclusion, and interior baiting.
Learn more →Mouse Control
Building-wide mouse exclusion for Brooklyn brownstones. We seal party wall penetrations, steam pipe chases, and basement access points to stop inter-unit mouse travel.
Learn more →Bird Control
Pigeon exclusion for Brooklyn brownstone cornices, commercial building ledges, and Williamsburg rooftops. Spikes, netting, and shock track systems installed discreetly.

How Wildlife Enters Brooklyn Buildings
Brownstone cornices and roofline edges
The ornamental cornice is the single most common raccoon entry point in brownstone Brooklyn. Limestone cornices crack, mortar deteriorates, and stone pieces separate — creating gaps large enough for raccoons to squeeze through into the cockloft above the top-floor ceiling.
Old coal chutes and areaway access
Many Park Slope and Carroll Gardens brownstones still have original coal chute covers or old areaway drain covers at sidewalk or backyard level. These deteriorated metal covers are rat-sized entry points directly to the basement.
Steam pipe chases and radiator penetrations
Pre-war brownstones have steam heating — and where steam pipes rise through floors, there are gaps. Mice travel vertically through buildings using these pipe chases, which are rarely sealed properly between floors.
Shared backyard areaway walls
Brooklyn’s signature shared mid-block backyards create open corridors between brownstone rear facades. Raccoons move across multiple properties via these connected yards, accessing rear facade climb routes on multiple buildings.
Cellar entry points and bilco doors
Many Brooklyn brownstones have separate cellar access via exterior Bilco doors or coal door openings. Deteriorated door frames and floor-to-wall gaps at the cellar perimeter are primary rat entry points.
Chimney flues and caps
Brooklyn’s brownstones have multiple chimneys — for fireplaces, old oil burners, and kitchen exhaust. Missing or deteriorated chimney caps allow raccoons to den in flues and birds to nest at flue openings.

Brooklyn Wildlife FAQs
Are there raccoons in Prospect Park Brooklyn?
Yes. Prospect Park supports a thriving raccoon population that radiates into surrounding neighborhoods — Park Slope, Windsor Terrace, Flatbush, Crown Heights, and Prospect Lefferts Gardens all experience regular raccoon pressure. Brownstone backyards that back up to the park's fence line have especially frequent visits.
Why do Brooklyn brownstones have so many mice?
Brooklyn brownstones are row houses sharing party walls, meaning mice can travel from one building to the next without ever going outdoors. Combined with aging mortar, gaps around old steam radiator pipes, and generations of patch-over-patch repairs, brownstones provide extensive internal mouse travel networks.
Who handles wildlife removal for a Brooklyn brownstone with shared walls?
Wildlife NY specializes in attached brownstone situations. We coordinate entry point identification across the full roofline and foundation perimeter and seal all penetrations with professional-grade materials that respect the historic character of the building.
What wildlife problems are common near the Gowanus Canal?
The Gowanus Canal area has historically high rat pressure due to industrial history, waterfront conditions, and proximity to restaurant-dense commercial blocks. Rat populations are substantial in Gowanus, Carroll Gardens, and Red Hook.
Can birds nest in Brooklyn brownstone cornices?
Absolutely. Brownstone cornices are prime nesting habitat for pigeons and house sparrows. Nesting activity accelerates masonry decay through moisture retention and uric acid from droppings. We install spikes and exclusion systems that protect cornice architecture while eliminating nesting.
