Gray Squirrels in Southern Maine:
Identification, Prevention, and Control
Gray squirrels are a familiar sight throughout Southern Maine, especially in the wooded neighborhoods of Biddeford and Saco. These agile rodents often seek shelter and nesting sites inside attics, soffits, and wall voids of older homes during colder months. If you hear daytime scrambling or notice new holes near your roofline, get your free inspection today.
What Are Gray Squirrels?
Gray squirrels, also known as eastern gray squirrels (Sciurus carolinensis), are medium-sized tree squirrels with light gray fur on their backs, white bellies, and large bushy tails. Some individuals in Southern Maine are the all-black melanistic form. They thrive in our humid coastal climate and hardwood forests, preferring areas with nut-producing trees like oak and beech. Diurnal and highly active during the day, they cache nuts and seeds for winter and readily adapt to suburban yards and older homes with easy roof access. They are one of several nuisance wildlife species that regularly enter Southern Maine attics and structures, and the one most likely to be active in broad daylight, making them easier to spot than many other wildlife pests.
According to the Maine Department of Inland Fisheries and Wildlife they are common throughout central and southern Maine.
Signs of Activity
These clues usually appear first in attics, soffits, fascia, or along the roofline.
- Daytime scratching or scampering noises in attics or walls
- Fresh 1½–2 inch chew holes in soffits, fascia boards, or roof vents
- Piles of rice-sized droppings mixed with nesting debris
- Leafy nests or pulled insulation inside attic spaces
- Gnaw marks on electrical wiring, plastic vents, or wooden beams
- Squirrels frequently running along power lines or the roof edge
- Damaged bird feeders or dug-up garden bulbs near the foundation
- Small entry tracks or stripped bark on trees close to the house
In Shapleigh and Windham homes these signs often increase in late fall and winter when squirrels seek warm shelter.
Risks in Southern Maine
In our damp, wooded region gray squirrels can pull insulation for nests, chew through wiring (creating fire hazards), and contaminate attic spaces with urine and droppings. Older homes in coastal towns are especially vulnerable because tree limbs often overhang roofs and provide easy highway access.
While they rarely transmit diseases to people, their activity can lead to costly structural repairs if left unchecked. My low-impact approach follows best practices from the Maine DACF Got Pests – Squirrels page and focuses on safe, targeted solutions for local conditions. Gray squirrels are most often confused with red squirrels, which are smaller, more aggressive, and cause similar attic damage but are identified by their rusty-red coloring and loud chattering, or with flying squirrels, which enter the same roofline gaps but are much smaller, strictly nocturnal, and almost never seen during the day.
Prevention Tips
Simple exclusion steps protect your home in Southern Maine.
- Trim all tree limbs at least 6–8 feet away from your roof and walls
- Seal potential entry holes with heavy-gauge metal flashing or hardware cloth
- Install a tight-fitting chimney cap and repair damaged soffits
- Use squirrel-proof bird feeders or bring feeders in at night
- Store trash in metal cans with locking lids and remove fallen nuts promptly
- Keep woodpiles and compost bins at least 20 feet from the house
- Install metal guards on downspouts and gutters
- Inspect and maintain roof vents and attic access points every season
These steps prove especially effective in Scarborough and Standish homes with overhanging trees and older construction.
Professional Treatment
When prevention is not enough I provide targeted, low-impact control. I locate active nests and entry points in attics, soffits, and rooflines. Treatments are customized for each property. A single family home in Biddeford may need different focus than a business in Saco. I handle the entire process myself from start to finish. Learn more about my background and methods on the About page. Contact me today to schedule your free inspection on the Contact page. If gray squirrels are getting into your attic or chewing through your roofline, my nuisance wildlife control services in Southern Maine provide humane removal and targeted exclusion to seal entry points and protect your home long term.
Frequently Asked Questions
They exploit small gaps as tiny as 1½ inches around rooflines, soffits, and chimneys, especially on homes with overhanging tree branches.
Yes, they are a native species, so I always use humane methods that comply with state regulations.
Rarely once they have built a nest and stored food inside your attic. Prompt action is the most effective way to encourage them to move out permanently.
