Why Squirrels Enter Homes During Certain Seasons

August 14, 2026

Squirrels are common wildlife visitors, but they can become a problem when they find a way inside a home. Their activity around houses can change throughout the year as they respond to weather, food availability, and nesting needs. Understanding why squirrels seek shelter can help homeowners recognize potential problems early.

Colder Weather Encourages Squirrels to Seek Shelter

With fall approaching, squirrels may soon begin looking for protected spaces where they can escape cooler temperatures and changing weather conditions. Attics, roof spaces, and wall voids can become attractive hiding places, offering shelter from the wind and rain as the seasons begin to change.

Nesting Can Increase Activity

Squirrels may seek enclosed areas to build nests and raise young. If they discover an accessible attic or other quiet part of a home, they may return to the same area repeatedly. This can lead to noises, nesting materials, and property damage.

Food Availability Can Influence Movement

Seasonal changes in food sources can affect where squirrels spend their time. When natural food becomes less available, squirrels may spend more time around homes, yards, and other areas where food or shelter can be found.

Homes Can Offer Easy Entry Points

Small openings around roofs, soffits, vents, chimneys, and other exterior features can provide access. Once a squirrel discovers an opening, it may continue using the same route to enter and exit the structure.

Seasonal Activity Doesn't Mean the Problem Will Resolve on Its Own

Even if squirrel activity becomes less noticeable, the animals may still be present or could return when conditions become favorable. Simply blocking an opening without determining whether wildlife is inside can also create additional problems.

Professional Wildlife Control Can Help

If you hear scratching or movement in your attic or notice signs of squirrel activity around your home, professional evaluation can help identify how the animals are getting inside and determine appropriate next steps.
