Most conventional pest control methods cause prolonged suffering for target animals, and humane alternatives are available and often more effective.
Pest animals are among the least welfare-protected animals in law and practice. Glue traps capture animals that then die of dehydration, exhaustion, or self-injury over hours or days. Second-generation anticoagulant rodenticides bioaccumulate up food chains, killing owls, foxes, and eagles. Humane alternatives — exclusion, live traps, habitat modification — are available and often outperform lethal methods in durability.
