As temperatures drop in the capital region, rodent control in Ottawa becomes a top priority for homeowners. Fall is the time when mice and rats begin seeking warm, sheltered spaces—making Ottawa homes a prime target. Understanding why rodent activity spikes and which areas of your home are most vulnerable can help prevent a full winter infestation.
Why Rodent Activity Increases in the Fall
When cooler nights arrive, rodents begin storing food, scouting new nesting areas and following heat sources around homes. Ottawa’s mix of older neighbourhoods, dense urban areas and nearby greenbelts creates the perfect environment for fall rodent movement.
Most homeowners notice an increase in:
- scratching or movement in walls
- droppings in storage areas
- gnaw marks around entry points
- activity in garages or basements
Many of these signs begin before winter even arrives, which is why fall inspections are so important.
Common Entry Points During Fall Rodent Season
Even small openings can allow rodents to enter your home. During fall, technicians often find activity around:
1. Foundation and Siding Gaps
Freeze–thaw cycles cause small cracks where siding meets concrete—ideal rodent pathways.
2. Utility Line Penetrations
Cable, gas and AC line openings often loosen over time, creating warm airflow rodents follow indoors.
3. Garage and Exterior Door Sweeps
If daylight is visible under a door, mice can enter. Fall moisture and temperature changes weaken door seals.
4. Attic and Roofline Access Points
Rodents climb vines, downspouts and exterior trim to reach attic spaces before winter.
