Mice in the Walls? Here’s Why It Happens Every Fall in NY Homes

Do you hear scratching, squeaking, or tiny footsteps inside your walls at night? If so, you’re not alone. Every fall, homeowners across New York and Connecticut notice signs of mice moving indoors — especially in Westchester County, Putnam County, and Fairfield County.

At Wings and Tails Wildlife, we specialize in humane mice exclusion and understand why these seasonal infestations happen, what dangers they bring, and how to protect your home before winter sets in.

Why Mice Move Inside Every Fall

When the weather changes, mice instinctively search for warmth and shelter. Homes provide insulation, safety, and easy access to food, making them the perfect hiding place. Unlike some animals that hibernate, mice stay active year-round. Once they’re inside, they’re likely to stick around all winter.


Mice are often drawn inside because of:

  • Warmth from attics, basements, and walls

  • Cracks and gaps as small as a dime

  • Easy access to food in kitchens, pantries, or storage bins

  • Seasonal cold that drives them out of fields and woodpiles



Why Mice in the Walls Are a Serious Problem

At first, a single mouse may not seem like a big concern. But mice are fast breeders, and what seems like one scratching noise in October can become an infestation by December. Beyond the nuisance, there are real risks to having mice inside your home.

  • Chewed Wires & Fire Hazards: Mice gnaw constantly, and electrical wiring is one of their favorite targets.

  • Contamination: Droppings and urine can spread harmful bacteria, trigger allergies, and contaminate stored food.

  • Insulation Damage: Nesting mice shred insulation, reducing your home’s energy efficiency.

  • Unsettling Noise & Odors: The scurrying, squeaking, and musky smell of mice quickly becomes disruptive.


Why DIY Mouse Control Doesn’t Work

Traps and poisons might reduce the population, but they rarely solve the real problem: how the mice are getting inside. Unless entry points are identified and sealed, new mice will keep moving in. DIY approaches also leave contamination behind and can put pets or children at risk if poisons are used.

At Wings and Tails Wildlife, our focus is professional exclusion. We don’t just remove the mice — we find the source, secure your home, and help you prevent future infestations.



How to Protect Your Home This Fall

The best defense against mice is prevention. With colder months ahead, homeowners should prepare before small problems turn into bigger ones.

Simple steps include:

  • Sealing cracks and openings around your foundation, doors, and windows

  • Storing food — including pet food — in airtight containers

  • Reducing clutter in basements, garages, and storage areas

  • Checking insulation for damage or droppings

  • Scheduling a professional inspection for peace of mind
