Wildlife Removal in Westchester County: Raccoons, Squirrels, and Groundhogs in Westchester Neighborhoods

Wildlife Conflicts Are Common in Westchester County

Westchester County is one of the most densely populated suburban counties in New York, yet it retains substantial wildlife habitat in its parks, preserves, and residential green corridors. This combination of dense human settlement and abundant wildlife makes wildlife-human conflict inevitable. Raccoons, gray squirrels, eastern gray squirrels, and groundhogs are among the most common wildlife species that cause problems in Westchester homes -- damaging attics, burrowing under decks and foundations, raiding gardens, and creating a range of structural and health issues for homeowners.

At Westchester County Pest Control, we provide professional humane wildlife removal and exclusion services throughout Westchester County. If you are hearing movement in your attic, finding damage to your garden or foundation, or seeing wildlife entering or exiting your home, call us at (914) 202-4197 for a free assessment.

Common Wildlife Conflicts in Westchester County

Raccoons

Raccoons are highly adaptable, intelligent, and extremely common throughout Westchester. They thrive in the wooded-suburban interface found in communities like Chappaqua, Pleasantville, Ardsley, and the Greenburgh area. Raccoon conflicts with homeowners typically involve:

Attic intrusion: Raccoons are powerful animals capable of tearing through rotted fascia boards, damaged roof vents, and weak soffit panels to access attic spaces. A female raccoon seeking a den site for her kits is remarkably persistent. Attic raccoons cause significant damage to insulation -- which they use for bedding -- and their latrines (communal defecation sites) create serious sanitation concerns, including the risk of Baylisascaris procyonis, a raccoon roundworm that can cause severe illness in humans.

Chimney nesting: Open masonry chimneys without caps are favored den sites for raccoon families. A female raccoon with kits in your chimney presents a removal challenge that requires professional handling.

Garbage and compost raiding: Raccoons are opportunistic omnivores and will consistently raid unsecured garbage cans, compost bins, and outdoor pet food.

Squirrels

Gray squirrels are among the most common attic invaders in Westchester County. The heavily treed residential neighborhoods throughout eastern and central Westchester -- Harrison, Mamaroneck, Larchmont, Scarsdale -- support dense squirrel populations. Squirrel attic access typically occurs via gaps at roof edge where fascia boards meet the roofline, through deteriorated gable vents, and along utility lines that connect to the structure.

Squirrels in attics cause significant damage:

- Gnawing on electrical wiring, which creates fire risk

- Tearing and compressing attic insulation to build nests

- Gnawing on wooden structural members and stored items

- Creating noise disturbances, particularly in early morning

Squirrel intrusions are most common in fall (when juveniles disperse) and late winter (when breeding activity increases nesting site competition).

Groundhogs

Groundhogs (woodchucks) are burrowing animals that create extensive tunnel systems under decks, porches, sheds, and foundations throughout Westchester residential neighborhoods. While generally not aggressive, groundhog burrows:

- Undermine deck and porch footings, creating structural instability

- Destabilize shed foundations and concrete slabs

- Destroy vegetable gardens and ornamental plantings -- groundhogs consume enormous quantities of vegetation during the growing season

- Create attractive secondary habitat for other wildlife and rodents

Groundhogs are most active from March through October in Westchester County and enter hibernation in late fall.

Diseases Associated With Wildlife

Wildlife in Westchester County carry several diseases of public health concern:

• Rabies: Raccoons are a primary rabies vector in New York. Any raccoon behaving abnormally (active during the day, disoriented, aggressive) should be treated as potentially rabid. Do not approach or handle. Call your local animal control.

• Leptospirosis: Raccoon and rodent urine can contaminate water and soil with this bacterial disease, which can cause serious kidney and liver illness.

• Baylisascaris: Raccoon roundworm eggs in feces remain viable in soil for years. Exposure can cause serious neurological and ocular disease.

• Distemper: Canine distemper is common in Westchester raccoon populations and is frequently mistaken for rabies by homeowners.

Professional Wildlife Removal and Exclusion

At Westchester County Pest Control, our wildlife removal process follows humane, effective protocols:

1. Property assessment: We identify all active entry points, assess the extent of the intrusion, and determine the species and approximate number of animals involved.

2. Exclusion planning: We identify every potential secondary entry point that could allow re-entry after removal.

3. Humane trapping: We deploy live traps or use exclusion devices (one-way doors) that allow animals to exit but not re-enter, depending on the situation and species.

4. Removal and relocation: Trapped animals are relocated per New York State DEC guidelines to appropriate habitat.

5. Exclusion work: After confirming all animals have been removed, we seal every entry point using professional-grade materials including heavy-gauge hardware cloth, steel flashing, and commercial caulk.

6. Sanitation guidance: For attic intrusions, we provide guidance on insulation assessment and decontamination needs.

Frequently Asked Questions

Is wildlife removal in Westchester County regulated?

Yes. New York State DEC regulations govern the trapping and relocation of wildlife. At Westchester County Pest Control, our technicians are properly licensed and follow all applicable state regulations. We handle all permitting requirements so you do not have to.

Can I handle wildlife removal myself?

We strongly advise against DIY wildlife removal. Raccoons and other wildlife can carry rabies and other diseases. Improperly handled animals may become aggressive. Additionally, removing animals without addressing entry points simply results in new animals taking the same route into your home. Professional exclusion is essential for lasting results.

What is the best time of year to address a raccoon or squirrel attic intrusion?

It depends on whether young are present. We assess each situation carefully to avoid separating mothers from dependent young, which causes additional problems. Contact us at any time for an assessment, and we will advise on the appropriate timeline and approach.
