Shop rat and mouse killers

Mouse killer or rat killer?

Rats and mice need different equipment. A rat trap is larger and stronger than a mouse trap, and rat stations have bigger entrances and more room for bait. Each rodenticide label lists the pests it is registered for, so check that the label names the animal you are dealing with — Norway rats, roof rats or house mice — before you buy. If you are not sure which rodent you have, droppings and gnaw marks are the quickest clues; our guides on getting rid of rats and getting rid of mice walk through the signs.

How to pick the right rat killer for your property

There is no single best rat killer for every situation. Start with the setting:

  • Inside living areas: traps avoid pesticide indoors. If you use a domestic rodenticide, it must stay in its bait station as the label directs.
  • Garages, sheds and cottages: traps or domestic bait stations, placed where children, pets and wildlife cannot reach them.
  • Farms and commercial buildings: a planned program with tamper-resistant stations and refill bait, run by someone permitted to use commercial-class products.

Whatever you choose, seal entry points and remove food sources at the same time. Killing rodents without fixing how they get in usually means the problem comes back — see the prevention checklist.

Questions before you order

Is a rat killer the same as rat poison?

Not always. “Rat killer” covers traps as well as rodenticide baits. Rat poison is the common name for a rodenticide bait; see rat poison in Canada for bait formats.

Can I use a commercial rat killer at home?

Health Canada limits commercial-class rodenticides to certified pest control operators, farmers and people authorized in government-approved programs. Homeowners should use domestic-class products, which come packaged with a bait station, or traps.

Do I need a bait station?

Yes for rodenticides. Domestic-class products must always be used in bait stations. Commercial labels specify tamper-resistant station requirements based on the location and who can access it.

Do you ship rat killers across Canada?

We ship by Canada Post with tracking. Online ordering is not available in Quebec. See where to buy rat poison in Canada for details.
