Fall Squirrel Activity: Why Attic Noise and Property Damage Increase Nov 13, 2025

As the seasons shift into fall, squirrel activity around homes reaches a noticeable peak. While squirrels are busy year-round, September through October is a particularly active period due to the birth of their second litter of the year. This new generation of young squirrels is ready to explore, and for many homeowners, that means an uptick in attic disturbances and property damage.

When squirrel litters are born in early fall, attics and rooflines often become the perfect nesting sites. As the young begin moving around, homeowners may hear scratching, scampering, or thumping noises overhead. These sounds are more than just a nuisance — they signal that squirrels have found access to the warm, sheltered spaces of a home, which can lead to larger issues if not addressed.

In addition to raising their young, squirrels are also in full preparation mode for the colder months ahead. Fall is when they begin caching food supplies, storing nuts and seeds to ensure survival during winter. This instinctive behavior often comes with increased gnawing activity, as squirrels chew on wood, wires, and even pipes in the process of sharpening their teeth and creating nesting spaces. Left unchecked, this chewing can damage insulation, electrical wiring, and other critical parts of a home.

Understanding squirrel behavior in the fall helps homeowners anticipate these problems before they escalate. Attic activity and gnawing are strong indicators that squirrels have made their way inside, and addressing the issue quickly can prevent extensive damage. Professional wildlife removal ensures that both adult squirrels and their young are safely relocated, while also sealing up entry points to prevent future invasions.

Fall is a beautiful season, but it’s also one of the busiest times for squirrels as they raise their young and prepare for winter.
