Law-makers in Canada and the United States are making moves to restrict the use of rodent poisons based on blood thinners, as studies show that the toxins accumulate in birds of prey and other animals.
The chemicals in question are anticoagulant rodenticides (ARs), which work like the human blood-thinning drug warfarin. Warfarin is itself used as a rat poison, but is what environmental toxicologists call a first-generation AR, less lethal and less prone to bioaccumulation than its second-generation successors.
Thanks so very much Ruth!
You do have to be mindful of the environment when or IF you use any poisons.
I surely don't want my neighbor cats harmed or wild birds that I attract to my feeders. What is a good alternative to keep mice out of my home and maintain a safe place for wildlife?
