Squirrel Control in Maine: Expert Removal & Prevention

squirrels may look cute in the backyard, but when they move into your attic, they become a destructive nuisance. In Maine, gray squirrels and red squirrels are common invaders, seeking warmth and nesting sites during two annual breeding seasons. Their constant gnawing can damage electrical wiring, insulation, and structural wood, creating costly problems and even fire risks. Professional squirrel control is often the safest, most effective solution.

Quick answer

In Maine, squirrels, especially red and flying squirrels, often enter attics during cold winters. Professional removal uses one-way doors and sealing to prevent re-entry. Look for scratching sounds, droppings, and chewed entry points. Contact a licensed wildlife control service for safe, effective removal.

Key Takeaways

  • squirrels enter attics through gaps as small as 1.5 inches and gnaw on wood and wiring, creating fire hazards.
  • Maine has two breeding seasons (late winter/spring and late summer/fall) when invasions spike.
  • One-way exclusion doors allow humane removal without trapping animals inside.
  • Professional exclusion and repair typically costs $250–$1,500; removal alone $250–$500.
  • Prevention includes trimming branches 10+ feet from rooflines and installing chimney caps.
  • Research: Fixr's January 2025 U.S. squirrel-removal cost guide estimates an inspection at $100 to $250, the same range it gives for dead-animal removal; both are publisher estimates rather than verified transaction prices or current local quotes.

The Problem

squirrels in Maine typically enter attics through gaps in rooflines, soffits, or vents. They can squeeze through openings as small as 1.5 inches—about the width of a golf ball. Once inside, they build nests, raise young, and gnaw relentlessly to keep their ever-growing incisors trimmed. This gnawing damages wood, drywall, and electrical wiring, creating both structural issues and fire hazards. In addition to property damage, squirrels carry parasites like fleas and ticks, and their urine and droppings can contaminate insulation, leading to odors and health concerns.

Warning Signs

  • Scratching or scurrying sounds in the attic, especially at dawn and dusk.
  • Chewed entry holes around rooflines, soffits, fascia boards, or vents.
  • Droppings (small, oblong pellets) in attic spaces or near entry points.
  • Nests made of leaves, twigs, and insulation in corners or on attic beams.
  • Gnaw marks on wood, electrical wires, or stored items.
  • Sightings of squirrels entering or exiting the roofline during daylight.
  • Unpleasant odors from urine, droppings, or decomposing animals.

Risks of Waiting

  • Electrical fires from chewed wiring.
  • Structural damage from gnawing on support beams and drywall.
  • Contamination of insulation with urine and feces, requiring costly removal.
  • Secondary infestations of fleas, ticks, or mites that squirrels bring.
  • Increased repair costs as damage worsens over time.

Treatment Options

Humane Exclusion with One-Way Doors

$250-$500

One-way exclusion doors are installed over entry points, allowing squirrels to leave but not return. Once all squirrels are out, the doors are removed and entry points are sealed.

1-2 weeks for full removal, plus sealingBest: Active infestations with known entry points

Full Exclusion and Repair

$500-$1,500

Comprehensive service that seals all potential entry points (gaps, vents, chimneys) and repairs any damage caused by squirrels. Includes installation of heavy-duty materials like steel mesh.

1-3 days for sealing, plus repair timeBest: Preventing future infestations and fixing existing damage

Trapping and Removal

$200-$400

Live traps are set to capture squirrels, which are then relocated (where legal) or euthanized. Less humane and less effective long-term without exclusion.

Varies, typically 1-2 weeksBest: Immediate removal of a few squirrels, but not a standalone solution

Squirrel Species You'll Meet in Maine

Maine has several squirrel species, each with its own habits. The eastern gray squirrel is common in urban areas and may nest in attics. The red squirrel is smaller and more aggressive, often entering homes in search of warmth. Flying squirrels are nocturnal and can be mistaken for mice. They live in colonies and can cause significant damage. Understanding which species you have helps in choosing the right removal method.

A Month-by-Month Timeline for Squirrel Activity in Maine

squirrels have two breeding seasons: late winter and mid-summer. In Maine, this means you may see an increase in squirrel activity in February and March, and again in July and August. During these times, mothers are looking for safe places to raise their young. If you have an attic, it becomes a prime target. To prevent infestations, inspect your home in early fall before the first snow.

What the First Visit from a Professional Looks Like

When you call a professional squirrel control service in Maine, they will first inspect your property. They will look for entry points, signs of activity, and identify the species. They may set up cameras or use other methods to confirm the location. After the inspection, they will provide a plan for removal and exclusion. This often includes installing one-way doors and sealing gaps.

What Affects the Price of Squirrel Removal in Maine?

The cost of squirrel removal in Maine varies based on several factors. The number of squirrels and the size of the infestation affect the price. Hard-to-reach areas, like tall rooflines, may increase the cost. The type of squirrel also matters, as flying squirrels may require more extensive work. Local labor rates and the need for repairs also play a role. Always get multiple quotes to compare.

Renters, Landlords, and Who Pays for Squirrel Damage

In Maine, landlords are typically responsible for pest control and repairs, but this can depend on the lease agreement. If you are a renter and notice squirrels, report it to your landlord immediately. They should handle the removal. If you own your home, you are responsible for the costs. Check with your insurance to see if squirrel damage is covered, as it may be considered a maintenance issue.

Prevention for Older Maine Homes

Many homes in Maine were built before 1980 and may have gaps that squirrels can enter. The median home value is around $330,000, and older homes often have original wood that is vulnerable. To prevent squirrels, inspect your roofline and soffits for damage. Seal any openings with metal flashing or hardware cloth. Trim branches that overhang the roof to limit access. These steps are especially important in the fall before winter.

When does a Maine squirrel problem become urgent?

Treat three things as urgent and schedule the rest. The first is anything electrical: a squirrel strips insulation from wiring the way it strips bark from a branch, and a bare conductor lying in loose attic cellulose is the one version of this problem worth a rushed call. The second is an animal loose in the living space, which is handled by opening one exterior door, closing every interior one, and leaving the room, not by chasing it with a broom. The third is water. Once a squirrel has opened a roof edge, the 47 inches of precipitation Maine averages each year follows it straight in, and the rot spreads faster than the animal ever will. Everything else, including scratching over the bedroom in February, is a scheduling question. Summer highs near 79F mean attics here do not cook a nest the way southern ones do, so you usually have room to collect two quotes and choose the company that puts the repair work in writing.

When to Call a Professional

If you hear consistent scratching in the attic, see squirrels entering the roofline, or find chewed entry points, it's time to call a professional. Squirrel removal is not a simple DIY task—improper sealing can trap animals inside, leading to death and odor. A professional will perform a thorough inspection, use humane exclusion techniques, and seal all gaps to prevent re-entry. Squirrel Removal offers inspection terms that vary by provider and a service guarantee; call +1 888 546 7983.

DIY vs Professional

DIY squirrel control often involves setting traps or sealing visible holes. However, squirrels are adept at finding alternate entry points, and improper sealing can cause more harm than good. Trapping without exclusion leaves the property vulnerable to new invaders. Professional services use one-way exclusion doors, inspect the entire roofline, and seal with durable materials like galvanized steel mesh. While DIY may cost less upfront, professional work typically lasts longer and prevents repeat infestations. For most homeowners, the investment in a pro pays off in peace of mind and property protection.

Local Context

In Maine, squirrel control needs vary by region. In Portland, the largest city, gray squirrels are the primary invaders, often entering attics via gaps around chimneys and vents. The mild coastal climate means activity peaks in March and September. In Augusta, the state capital, both gray and red squirrels are common, with homes near wooded parks facing higher risk. In Bangor, red squirrels dominate, and homeowners often report invasions in late fall as squirrels seek warm shelter. Northern regions like Aroostook County see less year-round pressure but experience intense bursts during early winter when temperatures drop sharply. Property managers in rural areas should prioritize sealing outbuildings and cabins, which are frequent targets. Squirrel Removal offers inspection terms that vary by provider statewide, with technicians familiar with local species and building styles. Call +1 888 546 7983 to schedule.

Prevention Tips

  • Inspect your home for gaps and holes in the roofline, soffits, and fascia.
  • Seal any openings larger than a quarter inch.
  • Trim tree branches that overhang your roof.
  • Install chimney caps and vent covers.
  • Remove bird feeders that may attract squirrels.
  • Store firewood away from your home.
  • Use squirrel-proof bird feeders.
  • Keep your attic dry and well-ventilated.

💡 Did You Know?

  • squirrels use elaborate fake-burying tactics to fool food thieves: they dig a hole, pretend to drop a nut, then cover it up, while actually hiding the nut in their mouth to bury elsewhere.
  • They can rotate their ankles 180 degrees to climb down trees headfirst, a feat few other mammals can match.
  • a squirrel's front incisors never stop growing—they grow about 6 inches per year, which is why they must gnaw constantly to keep them filed down.

Frequently Asked Questions

How do I know if I have squirrels in my attic?
Listen for scratching or scurrying sounds, especially at dawn and dusk. Look for chewed entry holes, droppings, nests, or gnaw marks on wires and wood. Sightings of squirrels entering the roofline are also a clear sign.
What is the best way to remove squirrels from my attic?
The best method is one-way exclusion doors, which allow squirrels to leave but not re-enter. Once all squirrels are out, seal every entry point with heavy-duty materials like steel mesh. This is humane and prevents future infestations.
Can squirrels cause a fire?
Yes. squirrels frequently gnaw on electrical wiring, stripping insulation and exposing live wires. This can cause short circuits and sparks, leading to attic fires. The NFPA estimates squirrels cause about 30,000 house fires annually in the US.
How much does professional squirrel removal cost in Maine?
Removal using exclusion doors typically costs $250-$500. Full exclusion and repair ranges from $500-$1,500 depending on the number of entry points and damage. Squirrel Removal offers inspection terms that vary by provider and a service guarantee.
When is squirrel season in Maine?
squirrels breed twice a year: late winter/spring (January–March) and late summer/fall (July–September). These are peak times for attic invasions. They also seek shelter during cold winter months.
Will squirrels leave on their own?
No. Once squirrels establish a nest in your attic, they will stay to raise young and return repeatedly. They are persistent and will not leave unless forced out through exclusion or trapping.
Is it legal to trap and relocate squirrels in Maine?
Maine law requires that trapped squirrels be euthanized or released on the same property. Relocation to other areas is generally not permitted because it can spread disease and disrupt ecosystems. Check with Maine Department of Inland Fisheries and Wildlife for current regulations.
How do I prevent squirrels from coming back?
Seal all gaps larger than 1.5 inches with steel wool and hardware cloth. Trim tree branches at least 10 feet from the roof. Install chimney caps and vent covers. Remove bird feeders or use squirrel-proof designs.
How much does it cost to remove a dead squirrel from a wall or attic?
Fixr's January 2025 U.S. cost guide estimates dead-squirrel removal at $100 to $250. That is a publisher estimate, not an observed customer bill, and local quotes vary, especially if the animal is inside a wall and drywall has to be opened. The smell usually peaks within a week or two and fades over several weeks. When you call, ask whether the price includes locating the carcass, disposal and deodorizing, since those are sometimes billed separately.
