Many Southern Ontario cities have seen a rise in rat activity over the last decade. Factors like urban growth, construction projects, warmer winters, and abundant food sources all contribute. As cities expand, rats lose nesting areas and move into neighbourhoods — often taking advantage of older drainage systems or structural gaps.
Signs you may have rat activity include:
- Grease marks along walls
- Large droppings
- Burrows near foundations
- Noises in walls or ceilings
- Damage to stored food
Rats reproduce rapidly, making early detection crucial. Homeowners can reduce risk by sealing gaps, securing garbage, removing clutter, and calling professionals if signs appear.
