HOW TO RAT-PROOF YOUR HOME OR BUSINESS
Last updated: Dec 1, 2025
Understanding Why Rat Activity Is
Increasing
Rats are excellent hitchhikers and opportunistic feeders. Abell Pest
Control reports rat inquiries rose 60% during the pandemic and remain 15%
higher in recent years. As restaurant dumpsters emptied during lockdowns,
rodents relocated to suburban areas and stayed. Construction disruptions,
including subway and LRT work, continue to displace rat colonies into new
neighbourhoods. Warmer winters have also extended their breeding season, helping colonies
grow larger and survive longer.
Nearly all urban areas within 100 km of Toronto now face persistent
rodent issues.
How to Rat-Proof Your Home
1. Seal All Entry Points
Rats can enter through a hole the
size of a quarter; mice need only a dime.
Inspect exterior walls,
foundations, vent covers, and roof shingles.
Seal gaps in brick, mortar,
siding, and utility entry points.
2. Remove Food Sources
Keep garbage in sealed
containers.
Never leave pet food outdoors.
Avoid using bird feeders, which
attract rodents.
3. Eliminate Shelter and Hiding Spots
Remove wood piles, cardboard,
leaves, and clutter.
Keep yards trimmed and clean to
reduce nesting areas.
4. Address Water Sources
5. When in Doubt, Call a Professional
If you suspect rats or mice are inside your home, contact a licensed
pest-control contractor immediately. Indoor infestations pose a more immediate
health risk than outdoor sightings.
How Businesses and Restaurants Can
Protect Against Rats
Commercial properties are especially susceptible due to food handling and
waste.
Key Steps:
Never prop open back doors. This is the most common entry
point for rodents.
Ensure dumpsters and waste bins
are fully closed and positioned away from entrances.
Inspect the building perimeter
regularly for new gaps or cracks.
Maintain a monthly
pest-management program with rodent stations inside and outside.
By adopting consistent prevention practices, both residents and
businesses can reduce infestations and help keep Rockwood Village clean and
healthy.
