Why New Hampshire Homes Attract Squirrels in Winter
Every winter, we see a surge in wildlife activity throughout Merrimack, Manchester, Bedford, Goffstown and surrounding New Hampshire towns. As temperatures plunge, outdoor nesting sites disappear and natural food sources dry up. Squirrels of all types begin targeting residential structures that provide heat, shelter and quiet nesting areas.
Attics, soffits, roof intersections and gable vents become winter sanctuaries. Homeowners often hear scratching, scurrying or thumping and assume it is just one kind of animal. In reality, knowing whether you have squirrels or flying squirrels is critical because their behavior, damage patterns and removal strategies are completely different.
The Biggest Mistake Homeowners Make
Most homeowners assume all squirrels are the same. They are not.
Tree squirrels and flying squirrels have distinct lifestyles, activity patterns and access methods. Treating them the same almost always leads to repeat infestations.
What Regular Squirrels Look Like and How They Behave
Tree squirrels are larger, louder and active during the daytime. They are commonly seen running along power lines, tree branches and rooftops before chewing into attic spaces.
They typically enter through rooflines, fascia boards and soffit corners. Once inside, they create large, obvious nesting zones using insulation and wood fragments.
Signs of a tree squirrel infestation include loud daytime thumping, torn roof shingles, chewed wood framing and visible damage around roof edges.
What Flying Squirrels Look Like and Why They Are So Dangerous
Flying squirrels are smaller, nocturnal and rarely seen. Instead of running, they glide between structures using a membrane between their front and back legs. Because of this, they often access homes from trees that do not even touch the roof.
Flying squirrels prefer attic rafters, wall voids and ceiling cavities. They build massive interconnected nesting systems that remain hidden for months.
Most homeowners do not realize they have flying squirrels until scratching noises appear only at night or insulation damage becomes severe.
How We Tell Which Species Is Inside Your Home: Squirrels and Flying Squirrels
We identify wildlife by behavior, noise patterns, droppings, access points and nesting design. Tree squirrels are active during the day and leave large entry holes. Flying squirrels are active after dark and leave minimal external damage.
Understanding the squirrels and flying squirrels species is the foundation of successful removal.
Why Flying Squirrels Are Often Misdiagnosed
Flying squirrels are silent gliders. They rarely run across open attic floors. Instead, they move inside framing cavities, which is why homeowners hear scratching inside ceilings rather than heavy footsteps overhead.
Because they remain hidden, infestations can grow for months before detection.
Damage Differences Between Squirrels and Flying Squirrels
Tree squirrels cause structural damage. They chew through wood, rip insulation apart and expose roof decking.
Flying squirrels cause system-wide contamination. Their urine and droppings spread through insulation, wall cavities and HVAC systems, degrading air quality and causing odor issues.
Why DIY Wildlife Control Always Fails
Store-bought traps and poisons do not address nesting networks or access routes. Removing one animal does nothing when multiple entry points remain open.
Without full-home exclusion, infestations return.
