Westchester County Wildlife Removal
Raccoon removal in Scarsdale and Bronxville, bat exclusion for historic Westchester homes, and squirrel control across all communities — from Yonkers to Bedford.
NYS DEC licensed. The highest raccoon density in the NYC metro region requires expert local knowledge.
Westchester County: The Raccoon Capital of the NYC Metro
Westchester County has earned an unenviable distinction: it has the highest raccoon density of any county in the New York City metropolitan region. From Yonkers and Mount Vernon in the urban south to the rural estate communities of Bedford, Pound Ridge, and North Salem in the north, every community in Westchester experiences raccoon pressure — the only variable is the intensity. In Scarsdale, Bronxville, Larchmont, and Pelham Manor, raccoons have been in residence for generations, producing multiple litters per year and thoroughly mapping every attic access point in the neighborhood.
The tree canopy is the driver. Westchester's inner suburbs were developed in the early 20th century, and the trees planted 80–100 years ago have grown to enormous sizes. Old-growth oaks in Scarsdale yards are large enough that their canopy contacts rooflines directly — raccoons don't need to climb the house at all, they simply walk from branch to roof. The same canopy drops millions of acorns annually, providing the food supply that sustains these dense populations. Combined with the suburban food bounty — outdoor trash, pet food, compost, bird feeders — Westchester raccoons have no reason to go hungry.
Bat populations are a secondary but significant issue throughout Westchester. The county's stock of Victorian-era, colonial revival, and craftsman homes — particularly in Yonkers, Pelham, Mount Vernon, and the river communities of Tarrytown, Hastings, and Dobbs Ferry — have the complex rooflines, aged wood fascia, and deteriorated masonry that bats exploit. All bat work requires careful NYS DEC compliance, which Wildlife NY manages completely.
Westchester’s Wildlife Pressure Points
Extreme Raccoon Density — All Communities
Every Westchester community has raccoons, but inner suburbs like Scarsdale, Bronxville, Larchmont, Pelham, and New Rochelle have among the densest populations in the Northeast. Old-growth tree canopy provides direct roofline access, and decades of suburban food availability have made these raccoons bold and resourceful.
Bat Colonies in Historic Architecture
Victorian-era homes in Yonkers, craftsman homes in Pelham, and colonial revival architecture in Bronxville provide excellent bat habitat — complex rooflines, aged wood fascia, and masonry gaps. Bat maternity colonies in Westchester homes can contain 20–200 individuals. Exclusion must be timed carefully to protect young bats.
Squirrel Pressure from Old-Growth Trees
Scarsdale, Ardsley, and Pleasantville neighborhoods have eastern gray squirrel populations at carrying capacity. The combination of abundant acorn production and direct tree-to-roofline access means squirrel exclusion is a high-demand service throughout the county.
Coyote Presence in Suburban Areas
Coyotes have established themselves throughout Westchester County, from Yonkers north to Bedford. While they rarely cause direct wildlife management problems, their presence changes the behavior of other wildlife and is a growing concern for small pet owners. Coexistence strategies are the primary management tool.

How Wildlife Enters Westchester Homes
Tree branches directly on rooflines
Old-growth oaks and maples in Scarsdale, Bronxville, and Larchmont yards grow large enough that their canopy rests directly on rooflines. Raccoons walk from branch to roof without climbing. Tree trimming is essential — exclusion alone is insufficient without addressing canopy contact.
Aging wood fascia and Victorian trim details
Westchester's extensive Victorian and colonial revival housing stock has complex roofline trim: decorative rake boards, bargeboard ornamentation, and multi-gabled designs with numerous fascia junctions. These age-deteriorated elements provide entry points for raccoons, squirrels, and bats.
Chimney flues and mortar gaps
Older Westchester homes with original brick chimneys have mortar deterioration that creates gaps at the chimney-wall junction — primary bat entry points. Missing chimney caps allow raccoon denning in flue liners throughout the county.
Foundation vents and crawl space access
Westchester homes with crawl space foundations have foundation vents that squirrels, skunks, and groundhogs exploit. Deteriorated vent screens are one of the most overlooked entry points during home inspections.
Garage roof edges and attached garage walls
Attached garages on Westchester colonial homes have vulnerable roof edges where the garage roof meets the house wall. This junction is a primary squirrel entry point throughout Westchester's residential neighborhoods.
Attic gable vents
Gable vents on Westchester colonial and craftsman homes have historically been fitted with wood-frame screens that rot and fail. Rusted or broken gable vent screens are the primary raccoon and squirrel entry point in older Westchester construction.

Westchester County Wildlife FAQs
Why does Westchester County have so many raccoons?
Westchester County has the highest raccoon density of any county in the NYC metro region. The combination of mature suburban tree canopy, abundant suburban food sources, and the relative absence of natural predators creates ideal conditions. Communities like Scarsdale, Bronxville, Larchmont, and Pelham Manor with large old-growth trees experience near-constant raccoon pressure.
Are there bats in Westchester homes?
Yes. Westchester County has significant bat populations, and older homes — particularly Victorian-era, colonial revival, and craftsman homes in Yonkers, Pelham, and historic village centers — have numerous bat entry points. Big and little brown bats are the most common species. Wildlife NY holds all required NYS DEC permits.
What's causing the wildlife surge in Scarsdale and Bronxville?
Scarsdale, Bronxville, and Larchmont have mature old-growth tree canopy — large oaks and maples planted in the early 20th century. These trees have grown to the point where their canopy directly contacts home rooflines, providing raccoon and squirrel access without requiring any climbing.
Does Wildlife NY serve all of Westchester County?
Yes. Wildlife NY serves all Westchester County communities including Yonkers, Mount Vernon, New Rochelle, White Plains, Scarsdale, Bronxville, Larchmont, Mamaroneck, Port Chester, Rye, Pelham, Ardsley, Dobbs Ferry, Hastings, Tarrytown, Ossining, Pleasantville, Chappaqua, Bedford, and every other Westchester community.
How do I handle a coyote problem in Westchester?
Coyotes are present throughout Westchester County and are legally protected in New York State. The most effective approach is habitat modification: securing trash, removing attractants, and installing coyote-deterrent fencing for small pet areas. Wildlife NY provides coyote coexistence consultation and deterrent installation.
