Mouse Poison in Canada: Mouse Bait & Bait Stations
House mice are the most common rodent problem in Canadian homes, cottages and businesses, especially in the fall. Mouse poison (mouse bait) can help control them, but it must be used inside a bait station and according to the Canadian label.

Mouse poison options
- Ready-to-use bait stations – pre-filled, tamper-resistant stations designed for homeowners.
- Refillable mouse bait stations – a reusable station you load with bait blocks. See mouse bait stations.
- Bait blocks and chunx – for commercial and farm programs; see all rodent baits.
Where to place mouse bait
Mice rarely travel far from their nest. Place stations every few metres along walls, behind appliances, in basements, attics and garages, and anywhere you see droppings or gnaw marks. Follow the spacing on the label.
Rules in Canada
In Canada, every rodenticide is registered by Health Canada's Pest Management Regulatory Agency (PMRA), and its label is the law. Products for domestic (homeowner) use must come ready to use in tamper-resistant bait stations, while the strongest single-feed anticoagulants (brodifacoum, bromadiolone and difethialone) are labelled for commercial or agricultural use only. Some provinces, including British Columbia and Quebec, add their own rules. See our Canadian label and regulation guide and provincial regulations.
Poison-free alternatives
Mouse snap traps, live and multi-catch traps and repellent pouches for cars, RVs and cottages are good options in kitchens and food areas.
Frequently asked questions
What is the best mouse poison for a house in Canada?
Homeowners should use a domestic product sold in a ready-to-use tamper-resistant bait station. Check that the label lists domestic use and the area where you plan to use it.
Where should I not put mouse poison?
Never place bait where children, pets, livestock or wildlife can reach it, or directly on food-preparation surfaces. Always use a bait station and follow the label.
Why do I still see mice after using bait?
Bait takes time to work, and new mice can keep coming in. Seal entry points larger than a dime, remove food sources, and combine bait stations with traps.
