Anticoagulant rodenticides used to control rats and mice cause prolonged suffering in target animals and secondary poisoning in predators that eat them. Welfare-conscious pest control alternatives exist and are increasingly used.
Anticoagulant rodenticides cause prolonged, painful deaths in target rodents and disrupt ecosystems by eliminating natural predators. The secondary poisoning of raptors and carnivores causes welfare harms across multiple species and removes the very predators that provide natural rodent population control. Humane alternatives including exclusion, trapping with immediate killing, and habitat modification address rodent problems without these cascading harms.
