Red Squirrels in Southern Maine:
Identification, Prevention, and Control
Red squirrels are a common sight throughout Southern Maine, especially in the wooded neighborhoods of Biddeford and Saco. These small, noisy, reddish-brown mammals frequently enter attics, soffits, and wall voids of older homes seeking food and shelter. If you hear loud chattering or scratching during the day or notice small holes near the roofline with piles of shredded cones, get your free inspection today.
What Are Red Squirrels?
Red squirrels, also known as American red squirrels (Tamiasciurus hudsonicus), are smaller than gray squirrels with bright reddish-brown fur, a white belly, and a bushy tail. They have prominent ear tufts in winter and measure about 7 to 8 inches long with an additional 4 to 5 inch tail. Highly territorial and vocal, they produce a loud “chick-chick” or “terrr” call.
They thrive in our humid coastal climate in coniferous and mixed forests where they cache pine cones and seeds in middens. Diurnal and extremely active during the day, they are common throughout central and southern Maine. They are one of several nuisance wildlife species that regularly enter Southern Maine attics and wall voids, and the one most likely to announce their presence with loud, persistent chattering before any physical damage is discovered.
According to the Maine Department of Inland Fisheries and Wildlife they are one of our most vocal and energetic small mammals.
Signs of Activity
These clues usually appear first in attics, soffits, fascia, or along the roofline.
- Loud chattering, barking, or scolding sounds during the day in ceilings or walls
- Small 1–1½ inch chew holes or gaps in soffits, fascia, or roof vents
- Piles of shredded pine cone scales (middens) in attics or on the ground near the house
- Tiny rice-sized droppings mixed with cone debris
- Gnaw marks on electrical wiring, plastic vents, or wooden beams
- Torn-up insulation used for nesting material
- Red squirrels frequently running along power lines or tree branches near the roof
- Damaged bird feeders or stripped bark on nearby conifer trees
In Cornish and Parsonsfield homes these signs often increase in late summer and fall when red squirrels are actively caching food for winter.
Risks in Southern Maine
In our damp, wooded region red squirrels can chew through wiring (creating fire hazards), pull insulation for nests, and contaminate attic spaces with droppings and urine. Older coastal homes with mature conifers close to the structure are especially vulnerable because red squirrels are smaller and more determined to enter than gray squirrels.
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. Red squirrels are most often confused with gray squirrels, which are considerably larger and less vocal but cause the same type of attic and wiring damage, or with flying squirrels, which are similar in size and enter through the same small roofline gaps but are strictly nocturnal and completely silent by comparison.
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 gaps and holes as small as 1 inch with heavy-gauge metal flashing or hardware cloth
- Install a tight-fitting chimney cap and repair damaged soffits or vents
- Remove fallen pine cones and clean up bird seed nightly
- Store trash and compost in metal cans with locking lids
- Keep woodpiles and brush 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 Newfield and Shapleigh homes with dense conifer trees and older construction.
Professional Treatment
When prevention is not enough I provide targeted, low-impact control. I locate active entry points and nesting areas in attics, soffits, and wall voids. 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.

If red 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 stop the damage.
Frequently Asked Questions
They squeeze or chew through small gaps as tiny as 1 inch around rooflines, soffits, vents, and chimneys, especially where trees touch the structure.
Yes, they are native wildlife. I always follow Maine regulations and prioritize humane exclusion and relocation whenever possible and permitted.
Rarely once they have built a nest and stored food inside your attic. Prompt exclusion is the most effective way to encourage them to move out permanently.
