Rodent poisons or “rodenticides” are legal and used widely to help homeowners, businesses, building owners and municipalities combat rodent infestations, but they are a serious risk to animals and the environment. Anticoagulant rodenticides are the most commonly used in Canada. These rodenticides thin the blood and prevent it from clotting, causing internal bleeding which results in a slow and painful death. Poisoned rodents, and the animals who become poisoned by eating their carcasses, slowly bleed out over hours, days or even weeks.

Rodenticides are also dangerous for owls, eagles, raccoons, cougars and even cats and dogs.  Rodenticide bait is made to smell like food to attract rodents, but its odour and flavour attracts many types of animals, putting them at risk of direct poisoning. Rat poisoning is injuring our local wildlife. Every year, hundreds of domestic and wild animals receive emergency medical care to combat the deadly effects of secondary poisoning from eating rodents killed by rodenticide, and unknown numbers of others suffer painful deaths.
