Squirrels behave differently throughout the year, and understanding their patterns can help you prevent infestations before they happen. Whether it’s breeding season, food storage time, or winter shelter-seeking, homeowners in Ottawa & Gatineau should stay ahead of the game.
Squirrel Behavior by Season & What Homeowners Should Do
Spring (March – May): Baby Season Begins
- Squirrels give birth to their first litters of the year.
- Mothers look for safe, warm nesting sites—attics are a top choice!
- Increased chewing behavior as they prepare their nest.
Homeowner Tip: Inspect attics in early spring to catch squirrel activity before they settle in with their babies.
Summer (June – August): Nesting & Food Hoarding
- Squirrels prepare for winter by storing food.
- They become more active around roofs, vents, and trees, leading to damage.
- High population growth from spring-born squirrels maturing.
Homeowner Tip: Trim tree branches near your house to reduce roof access.
Fall (September – November): Searching for Warmth
- The second breeding season begins—more baby squirrels are on the way.
- Attics become a prime shelter for winter survival.
- Heavy chewing to build stronger nests.
Homeowner Tip: Look for squirrel droppings or chewed wood near your roof and vents.
Winter (December – February): Full Infestation Mode
- Squirrels hunker down in attics for warmth.
- Increased urine and feces buildup creates odors & contamination.
- The risk of wiring damage and insulation destruction peaks.
Homeowner Tip: If you hear scratching in your attic, call Aspen Wildlife Control immediately to prevent costly winter damage.
