Preparing for Winter: How Fall Squirrel Activity Impacts Your Home Sep 26, 2025

Fall is one of the busiest times of year for squirrels, and their seasonal habits often bring them into direct conflict with homeowners. Between September and October, many squirrels are raising their second litter of the year, which makes attics and rooflines particularly attractive as safe nesting areas. As the young begin to explore, homeowners may notice scratching, scampering, or thumping noises coming from above — clear signs that squirrels have moved in.

But nesting is only part of the story. Fall also marks the beginning of food storage season for squirrels. This instinct, called caching, drives them to collect and hide acorns, nuts, and seeds in preparation for winter. While this behavior is natural, it can become destructive when squirrels gain access to homes. Their constant chewing not only sharpens their teeth but also allows them to create and expand entry points. Unfortunately, this gnawing doesn’t stop at wood — electrical wiring, PVC pipes, and insulation are also at risk, leading to costly and sometimes dangerous damage.

For homeowners, the combination of new litters and increased caching activity makes fall the most important time to stay vigilant. Even minor signs, such as chewing around eaves or unusual attic noises, can indicate that squirrels are settling in. Addressing these issues early prevents them from turning into larger infestations and reduces the risk of property damage.

Professional wildlife removal services offer a safe, humane way to handle squirrel problems while also securing entry points to keep them out for good. With expert help, homeowners can protect both their property and the animals, ensuring squirrels return to the wild where they belong.

As squirrels prepare for the winter ahead, taking proactive steps now will save time, stress, and money later. Fall is a season of preparation not only for wildlife but for homeowners too — and keeping your attic squirrel-free should be at the top of the list.
