When You Need to Deal With Squirrels in New England

 

Most people should start dealing with squirrels in New England as soon as they notice signs of squirrels inside their home, attic, or in structures (like garages or sheds) — not just outside in the yard. Squirrels become a problem when they get indoors, cause property damage, or are acting unusually aggressive. As a professional, I always tell people: If you hear scratching or footsteps above your ceiling (especially early morning or evening), see chewing damage, or find droppings or nest material, it’s time to take action right away.

 

Key Signs It’s Time to Intervene

 

• Noise in Walls or Attic: Scratching, chewing, or fast pattering can signal squirrels have moved in. You’ll often hear most activity at dawn and dusk, because squirrels are diurnal (active during the day).
• Visible Entry Points: Damaged soffits, popped-up roof shingles, or gnawed holes around vents and eaves indicate squirrels are forcing their way inside. Squirrels can squeeze through holes as small as 2 inches across.
• Chewed Wires or Insulation: Squirrels have constantly-growing teeth and must gnaw. Inside, they chew wiring (fire hazard) or shred insulation for nesting — this causes expensive repairs and risks.
• Nests or Droppings: Bedding made of insulation, leaves, or other gathered materials is a clear sign. Droppings (generally oval and about the size of a raisin) may be found in attic or storage spaces.
• Unusual Squirrel Activity: Squirrels that are bold, aggressive, or approach people/ pets may be sick, injured, or desperate for food — all situations that require quick action for safety.

 

Why Prompt Squirrel Control Matters

 

Squirrels cause more than just noise. Left unchecked, they can chew holes through wood, wiring (risking fire), and vents, cause insulation damage, contaminate areas with droppings (health risk), and can even attract other pests like insects or larger animals. In spring and late summer, squirrels search for places to have babies, making your attic more attractive. Breeding seasons can lead to sudden infestations — acting quickly prevents a much larger and more expensive problem.

 

The Best Times of Year to Be Extra Vigilant

 

• Late Winter (February-March): Squirrels start looking for cozy nesting spots to have their spring babies. This is often when first signs appear indoors.
• Late Summer (August-September): A second round of nesting means more attempts to get inside — especially as young squirrels learn to find food and shelter before the cold sets in.

Year-round, you should watch for signs of entry, but these two times are most common for new “invasions.” Quick response is important during these months.

 

What to Do If You Suspect Squirrels

 

• Inspect Your Home: Check attic, crawl spaces, and roof where you hear noises. Look for holes, gnaw marks, and debris.
• Don’t Close Holes Immediately: If squirrels are inside, closing entry points can trap and stress them, causing more damage or leading to dead animals that are hard (and expensive) to remove.
• Call a Professional: Wildlife specialists know how to humanely remove squirrels, identify and seal all entry points, and advise on prevention. Professionals can also check for electrical or insulation damage and clean contaminated areas.
• Prevention: Seal gaps, trim tree branches that touch your roof (these act as squirrel highways), keep food (birdseed, pet food) sealed, and inspect the house each season.

 

Summary: When to Deal With Squirrels

 

Act as soon as you hear or see evidence of squirrels inside walls, attic, or any part of the house structure — even a single squirrel is a problem worth handling immediately. Pay special attention during late winter and late summer, as these are peak nesting times. Waiting can make the problem much worse and more expensive. Outside in the yard, as long as squirrels aren’t causing damage or threatening people/pets, they’re usually not a direct problem. But as soon as they target your house as a nesting spot, quick, professional action is essential to protect your home and health.
