Quick answer

In New York, squirrels like gray, red, and flying squirrels can invade homes, especially during breeding seasons and winter. You can trap them yourself, but you cannot relocate them off your property. The most effective approach is exclusion plus one-way doors, timed around litters to avoid trapping babies inside.

The Problem

New York has three main squirrel species that cause problems: the eastern gray squirrel, the red squirrel, and flying squirrels. Gray squirrels are the most common attic invaders, active during the day, while flying squirrels are nocturnal, often mistaken for mice due to their small size and nighttime habits. Red squirrels are smaller and more aggressive, sometimes entering homes in search of nesting sites. New York's climate, with cold winters in the north and milder conditions downstate, drives squirrel behavior. In colder regions like Syracuse, squirrels seek warm attics as early as October, while in New York City, activity can be year-round. The state's older housing stock, with its gaps and soffits, offers easy access, especially in cities with many pre-1980 homes.

Warning Signs

  • โ€ขScratching or scurrying sounds in the attic, especially at dawn and dusk.
  • โ€ขDroppings that are oblong, about 3/8 inch long, often near entry points.
  • โ€ขGnaw marks on wood, wires, or plastic pipes.
  • โ€ขVisible entry holes in soffits, fascia, or roof edges, often 1.5โ€“2 inches wide.
  • โ€ขNesting materials like leaves, twigs, and shredded insulation in the attic.
  • โ€ขSquirrel sightings near roof edges or running along power lines toward your house.
  • โ€ขStrong, musky odors from urine or decaying food caches.

Risks of Waiting

  • โš Electrical fires from gnawed wiringโ€”squirrels cause hundreds of house fires annually.
  • โš Structural damage to roof framing, fascia, and soffits.
  • โš Contamination of insulation with urine and feces, requiring costly removal.
  • โš Secondary infestations of fleas, mites, or flies attracted to nesting debris.
  • โš Increased difficulty and cost of removal as squirrels establish complex nests.

Which squirrels invade New York homes?

New York has several squirrel species, but the ones you are most likely to deal with are the eastern gray squirrel, the red squirrel, and flying squirrels. Gray squirrels are the largest and most common, often nesting in attics and chewing through soffits. Red squirrels are smaller, more agile, and can be more aggressive, sometimes entering homes in search of food or shelter. Flying squirrels are nocturnal and are often mistaken for mice because of their small size and grayish-brown fur. A dozen or more will share one attic through a New York winter, and the rustling starts after dark rather than at sunrise. In New York, the DEC classifies red and flying squirrels as unprotected, meaning you can take them at any time without a limit. Gray squirrels are game animals with a hunting season, but you can still take them if they are causing damage, provided you follow state regulations.

A month-by-month timeline for squirrel problems in New York

Squirrel activity in New York follows their breeding cycles and the changing seasons. Gray squirrels typically have two litters: one in late winter (February to March) and one in mid-summer (July to August). This means you are most likely to hear babies in your attic in early spring and late summer. In the fall, as temperatures drop, squirrels become more active in seeking warm nesting sites, so October and November are peak times for invasions. Winter is quiet but if squirrels have taken up residence, you will still hear them. In the spring, young squirrels may leave the nest, but new mothers may also be looking for nesting sites. By late spring and early summer, the second breeding season begins. Understanding this timeline helps you time your exclusion efforts: avoid sealing holes when young are likely present, typically late winter and mid-summer.

What the first visit from a squirrel control pro looks like

When you hire a licensed nuisance wildlife control operator (NWCO) in New York, the first visit is usually an inspection. The pro will walk around your home, looking for entry points such as gaps in the roofline, soffits, vents, and chimneys. They will also inspect your attic for signs of squirrels, including droppings, tracks, and nests. They may ask about the timing of noises to determine if there are babies. After the inspection, they will provide a plan that includes sealing entry points, installing one-way doors, and possibly trapping. They will also explain the legal requirements, such as the need to release squirrels on your property if trapped. The cost of this inspection is often included in the overall quote, but it is a good idea to ask beforehand.

What affects the price of squirrel removal in New York homes

Ask any bidder to price three things separately: getting the animal out, closing the building, and cleaning up after it. That split tells you more than a single number, and it lets you set two quotes side by side. The count of openings is the biggest line. One chewed corner over a porch roof is a short job. Four gaps along a soffit run, a lifted ridge vent and a gable louver with a hole in it is a day of ladder work with metal and hardware cloth. Season is the second lever. Litters arrive in midwinter and again in early summer, and a nest of young means the crew returns rather than closing the wall on them. Every extra trip shows up in the total. Old New York housing stock adds a third. Wood soffits, plaster and knob and tube era framing hide damage that only shows once someone is inside the attic. Chewed wire and matted insulation become their own line item. Roof access is the last. A steep slate or a four story walk up needs staging that a ranch never does.

Renters, landlords, and who pays for squirrel damage in New York

In New York, landlords are generally responsible for maintaining a habitable dwelling, which includes keeping out pests like squirrels. If you are a renter and squirrels have entered your apartment, you should notify your landlord immediately. The landlord is usually responsible for hiring a pest control professional and paying for repairs. However, if the squirrel entry is due to your actions, such as leaving a window open, you might be held liable. It is important to document the issue and communicate in writing. For landlords, dealing with squirrels promptly is crucial, as damage can escalate and lead to bigger problems, such as electrical fires. Preventative maintenance, like sealing gaps and trimming trees, is a cost-effective way to avoid these issues.

When is a squirrel problem an emergency in New York?

Scratching overhead can usually wait a few days for a scheduled visit, though a handful of situations cannot. If you see chewed wires, this is a fire hazard and needs immediate attention. If a squirrel gets into your living space, it can cause chaos and may bite if cornered. In such cases, you should open a window and try to guide it out, or call a professional if it does not leave. Another emergency is if you suspect a squirrel is trapped in a wall or chimney; they can die and cause odors. If you hear frantic scratching or crying, it might be an injured animal. In all these cases, contacting a NWCO immediately is the safest course. Do not attempt to handle a squirrel yourself, as they can carry diseases and may bite.

How to compare two squirrel control quotes in New York

When comparing quotes from squirrel control companies in New York, look beyond the total price. Ask each company for a detailed breakdown of what is included: inspection, exclusion methods, trapping, cleanup, and any repairs. Make sure they are licensed by the DEC as NWCOs if they are trapping. Check if they guarantee their work, as this can save you money if the problem recurs. Also, ask about the timeline: how long will the exclusion take, and when will they follow up? A cheaper quote might not include the same level of service, such as sealing all potential entry points versus just the obvious ones. Finally, consider the company's experience with New York squirrels, as local knowledge is valuable. Getting at least three quotes will give you a better sense of the market rate and what to expect.

When to Call a Professional

Call a professional if you hear squirrels in the attic during late winter or mid-summer, as babies may be present. If you cannot safely access your roofline, have multiple entry points, or if DIY attempts have failed, a pro is worth the cost. Also, if you are unsure about the legalities of trapping, a New York State licensed nuisance wildlife control operator (NWCO) can handle removal legally and safely.

DIY vs Professional

DIY squirrel control can work for a single entry point and a squirrel that has not yet had babies. One-way doors and sealing holes are within reach of many homeowners. However, DIY comes with risks: you might trap babies inside, leading to death and odor, or you might miss entry points, leading to recurrence. Professionals have the experience to find all access points, the equipment for high roofs, and the knowledge of New York's wildlife laws. If you choose DIY, always check for young before sealing any hole, and never relocate a squirrel off your property, as it is illegal in New York.

Local Context

New York's squirrel problem varies by region. In the colder upstate cities like Buffalo and Syracuse, squirrels seek warmth in attics starting in early fall, and the heavy snow can push them into homes. Downstate, in places like Yonkers and Hempstead, the milder climate means year-round activity, but the older housing stock, with its many gaps, still offers easy access. The state's diverse geography, from the Adirondacks to the coastal plains, supports different squirrel species, and the legal framework, administered by the DEC, is uniform: you can protect your property, but you cannot relocate squirrels off your property. This means that prevention and exclusion are your best allies, no matter where in New York you live.

Prevention Tips

  • โœ“Trim tree branches to at least 10 feet from your roofline.
  • โœ“Install a metal chimney cap and screen vents with 1/4-inch hardware cloth.
  • โœ“Repair loose soffits, fascia boards, and roof shingles immediately.
  • โœ“Seal gaps around pipes, cables, and vents with steel wool and caulk.
  • โœ“Remove bird feeders or place them on poles with baffles far from the house.
  • โœ“Inspect your attic twice a year (spring and fall) for signs of entry.
  • โœ“Use a motion-activated sprinkler or ultrasonic repellent for ground-level deterrence.

๐Ÿ’ก Did You Know?

  • โ˜…squirrels perform elaborate fake-burying to deceive thievesโ€”they dig a hole, pretend to drop a nut, then cover it without actually leaving the nut.
  • โ˜…squirrels can rotate their ankles 180 degrees, allowing them to climb down trees headfirst.
  • โ˜…a squirrel's front teeth never stop growing; they wear them down by gnawing about 100 times per minute.

Frequently Asked Questions

Is it legal to trap and relocate a squirrel in New York?
No, it is illegal to relocate a squirrel off your property in New York. If you trap a gray squirrel, you must release it on your property or humanely euthanize it. The DEC recommends hiring a licensed nuisance wildlife control operator (NWCO) for removal.
What do I do if I find baby squirrels in my attic in New York?
If you find baby squirrels, the best course is to wait until they are old enough to leave on their own, which usually happens within a few weeks. You can also contact a NWCO to safely exclude them after they have left. Never seal the entry point while young are inside.
How can I tell if I have flying squirrels in my attic in New York?
Flying squirrels are nocturnal, so if you hear scratching at night, that is a clue. They are also smaller than gray squirrels, about the size of a chipmunk, and have a flap of skin between their legs. Their droppings are similar to mouse droppings but slightly larger.
Do squirrels hibernate in New York?
No, squirrels do not hibernate. They remain active all year, but they may be less active during severe winter weather. They often seek shelter in attics to stay warm, which is why you might see an increase in squirrel problems in winter.
What is the best time of year to exclude squirrels in New York?
Aim for the stretch between the two litters, once June's young are out and before the December breeding starts again. This timing helps avoid trapping young inside. You should also avoid exclusion during the breeding seasons in late winter and mid-summer.
Are squirrels protected in New York?
Eastern gray squirrels are considered game animals and have a hunting season. Red and flying squirrels are unprotected. However, you may take squirrels that are causing damage to your property, but you must follow state regulations regarding hunting licenses and methods.
Can I use poison to kill squirrels in New York?
Using poison is generally not recommended and may be illegal. It can harm non-target wildlife and pets, and it can lead to squirrels dying in hard-to-reach places, causing odors. The DEC advises against poisoning for nuisance wildlife.
How do I keep squirrels from chewing on my house in New York?
squirrels chew to wear down their teeth, so they will gnaw on wood, wires, and even siding. To prevent damage, seal all entry points, install metal flashing around vulnerable areas, and provide alternative chewable items like branches or corn cobs away from your home.
What should I do if a squirrel gets inside my living space in New York?
If a squirrel is inside your home, open a window or door and give it an escape route. Close off other rooms to guide it out. Do not try to catch it with your hands. If it does not leave, call a professional.
