Westchester County Pest Control
Protecting Westchester homes and businesses from Mt. Vernon to White Plains and beyond.
Pest Control Experts in Westchester County
Westchester County blends dense cities, wealthy riverfront suburbs, and genuinely wooded rural land into one of New York's most diverse pest environments. From the urban corridors of Yonkers and New Rochelle to the wooded hillsides of Pound Ridge and Bedford, each area brings its own pest pressure — and our team serves all of it from our Mt. Vernon location.
Ticks are Westchester County's most urgent pest issue. Deer populations in Westchester's abundant preserved lands — Rockefeller State Park Preserve, Ward Pound Ridge Reservation, Teatown Lake Reservation — push ticks into residential yards across the county. Westchester has historically reported among the highest Lyme disease infection rates in New York State. Protective yard treatments from April through October are strongly recommended.
Carpenter ants are the structural pest we see most frequently in Westchester. The county's older housing stock — Victorian and craftsman homes in Tarrytown, Sleepy Hollow, Ossining, and Hastings-on-Hudson — features mature wood framing, old-growth porch lumber, and decades of moisture accumulation. These conditions are ideal for carpenter ant colonies, which can number in the tens of thousands before homeowners notice structural damage.
Westchester's mix of urban and suburban housing also means rodent pressure in the denser communities along the Metro-North corridor. Yonkers, New Rochelle, and Mount Vernon see mice and rats move through dense neighborhoods particularly in fall and winter. Our Mt. Vernon office allows us to respond rapidly throughout the county.
Local Housing & Pest Risk
Westchester's housing ranges from pre-war Victorians and craftsman homes (1880s-1930s) in river towns to post-war capes and ranches in inland suburbs, with the older stock particularly vulnerable to carpenter ants, termites, and rodents due to aging wood framing and foundation gaps.
Westchester County Seasonal Pest Guide
Pest pressure changes with the seasons. Here's what to watch for in Westchester County throughout the year.
Spring
Tick season officially begins in Westchester in late March and ramps up through May. Carpenter ants emerge from overwintering sites in wood framing and tree stumps. Termite swarms can occur in older homes throughout April, May, and June.
Summer
Summer is tick season peak in Westchester. Wooded properties in Scarsdale, Ardsley, Briarcliff Manor, and Larchmont see intense tick pressure from deer. Mosquitoes breed in ornamental water features and shaded low areas common in Westchester's larger residential lots.
Fall
Stink bugs are a major Westchester fall pest, gathering on south-facing walls of homes before entering through gaps around windows and doors. Yellow jacket colonies reach maximum aggression in September. Mice begin entering homes as temperatures fall.
Winter
Rodents move indoors during Westchester winters, especially in older homes with gap-ridden foundations in Tarrytown, Ossining, and Peekskill. Silverfish are common in humid basements and older homes with paper and wood storage.

Frequently Asked Questions About Pest Control in Westchester County
Common questions from Westchester County homeowners about pest control services, costs, and what to expect.
Are ticks really that bad in Westchester County?
Yes — Westchester consistently ranks among the highest counties in New York State for Lyme disease cases. The large deer populations in preserved parkland like Rockefeller State Park and Ward Pound Ridge push ticks directly into residential yards across the county. We strongly recommend professional tick treatments from April through October for any property with wooded borders or deer traffic.
What areas of Westchester do you serve?
We serve all of Westchester County from our Mt. Vernon location — including Yonkers, New Rochelle, White Plains, Scarsdale, Mamaroneck, Larchmont, Pelham, Eastchester, Bronxville, Tarrytown, Sleepy Hollow, Ossining, Peekskill, Rye, Port Chester, Harrison, Dobbs Ferry, and all communities in between.
Do you treat for carpenter ants in older Westchester homes?
Absolutely — carpenter ant treatment is one of our most frequent services in Westchester County. Older homes in Tarrytown, Ossining, Hastings-on-Hudson, and similar river towns often have moisture-damaged wood framing that carpenter ants exploit. We locate colonies, treat harborage areas, and identify moisture sources that attract them.
How do stink bugs get into Westchester homes?
Stink bugs (brown marmorated stink bugs) move toward warm structures in September and October, clustering on south-facing walls before squeezing through window frames, door weatherstripping gaps, and utility penetrations. Westchester homes with stone or brick exteriors are particularly susceptible as the masonry retains heat. We treat exterior perimeters in late summer to intercept them before they enter.
Is same-day service available in Westchester County?
Yes — we offer same-day and next-day appointments throughout Westchester. Call (631) 563-3900 and our team will get you scheduled quickly. Our Mt. Vernon location means we can typically reach anywhere in the county within the same day.
How do I know if I have termites vs. carpenter ants?
Both can cause structural damage, but they're different insects requiring different treatments. Carpenter ants push out coarse, wood-shaving frass (often with insect parts) and don't eat wood — they excavate it. Termites leave fine mud-colored frass in distinctive pellet shapes or build mud tubes along foundation walls. If you're unsure, call us for a free inspection — we'll identify exactly what you're dealing with.
