Vertebrate Pest Control and Non-Target Species Welfare

Rodenticides, traps, and other pest control methods frequently injure or kill non-target species, creating welfare harm extending far beyond intended pest populations.

Key Facts

Second-generation rodenticides accumulate in raptors, foxes, and badgers eating poisoned rodents
Snap traps and leg-hold traps injure non-target species including domestic cats and endangered mustelids
Brodifacoum and difethialone have been found in a majority of tested wild predator species in urban areas
Non-toxic alternatives including live trapping and exclusion have proven effective in many settings

Welfare Considerations

Vertebrate pest control creates welfare harms across species far beyond targeted pests. Rodenticide secondary poisoning causes internal hemorrhage in raptors, foxes, and other predators that eat poisoned rodents over weeks of painful decline. Indiscriminate trapping injuries non-target species that then die slowly or escape with permanent injuries. The welfare solution is not abandoning pest control but selecting methods with specificity for target species and minimal non-target impact. Exclusion, live trapping with humane euthanasia, and first-generation rodenticides that do not bioaccumulate are all viable alternatives in most settings.

What You Can Do

Avoid second-generation rodenticides in and around your home — use alternatives or first-generation products
Advocate for restrictions on second-generation rodenticide availability to non-professional users
Support research into species-specific pest control methods with minimal non-target impact
Report suspected non-target rodenticide poisoning of wildlife to local wildlife authorities
