Squirrels in the Bronx
In the Bronx, squirrel issues concentrate in Riverdale, Fieldston, Throgs Neck, and neighborhoods bordering Van Cortlandt Park, Pelham Bay Park, and the Bronx River corridor. Larger homes with wooded lots, slate or wooden roofs, and old chimneys give squirrels many entry points. Flying squirrels are occasionally found in wooded areas and may enter attics at night.
The fastest results come from pairing targeted treatment with exclusion and sanitation fixes. A Bronx exterminator will explain what’s attracting squirrels, what they’ll treat, and what you can do between visits.
Eastern gray squirrels are a familiar sight in every NYC park, but they become a real problem when they move into attics, walls, soffits, and eaves. Squirrels chew constantly, and once inside they can gnaw through wiring, tear up insulation, and create new openings that let water and other animals in. The telltale sound is scurrying and scratching overhead in the early morning and late afternoon. NYC Pest Control Pros is a free referral service that connects homeowners with independent, licensed wildlife professionals who remove squirrels humanely and keep them out.
Signs of Squirrels in Your Bronx Home
- Scratching, scampering, or rolling sounds in the attic or ceiling, mostly in the early morning and late afternoon.
- Chewed holes in soffits, fascia boards, roof vents, siding, or along the roofline, often with rough, gnawed edges.
- Squirrels repeatedly running along gutters, utility lines, or branches that lead directly to your roof or chimney.
- Leaves, twigs, and shredded insulation packed into attic corners, eaves, or wall cavities as nesting material.
- Chewed electrical wiring, damaged insulation, or stained ceiling spots caused by urine in the attic.
How Squirrel Removal Works in the Bronx
- 1
Inspection
The pro inspects the roofline, soffits, eaves, vents, chimney, and attic to find active entry holes, secondary openings, and nest locations. They note overhanging branches, utility lines, and nearby trees that give squirrels access, and determine whether young are likely to be present.
- 2
Exclusion Plan
Based on the inspection, the pro outlines a plan to remove squirrels using one-way exclusion doors or humane traps where appropriate, along with repairs to all openings. During breeding seasons, timing is adjusted so young squirrels are not sealed inside the attic.

Humane Removal
One-way doors are installed on the main entry hole so squirrels can leave to feed but cannot get back in, and other openings are sealed first. If trapping is needed, the pro handles animals in accordance with NYS DEC nuisance wildlife regulations.

Sealing & Repair
After squirrels are confirmed out, the exclusion device is removed and the opening is sealed with galvanized steel mesh, metal flashing, or other chew-resistant materials. Vents are covered with heavy-gauge screens, and damaged soffits or fascia may need carpentry repair.

Cleanup & Prevention
Nesting material, droppings, and soiled insulation can be removed and the area sanitized. The technician recommends trimming branches back from the roof and adjusting bird feeders, and may schedule a follow-up check to make sure no new holes have appeared.
Seasonal Activity in the Bronx
In NYC, squirrel problems typically spike in fall, when squirrels look for warm places to overwinter, and in late winter and early spring, when females seek nesting sites for their first litter. A second breeding period in summer brings another round of attic nesting. Squirrels are active year-round, but homeowners often notice them most from September through March.
Bronx pest activity shifts noticeably through the year. Spring brings more rat activity in parks and yards, ant invasions, and termite swarms in wood-frame homes. Summer heat increases cockroach sightings in apartment buildings and waterbugs in basements. In fall, mice and wildlife such as raccoons and squirrels look for shelter indoors. Winter keeps rodents and roaches active in heated buildings, where steam heat and radiator gaps give them comfortable harborage.
