Urban and agricultural wildlife control raises significant welfare concerns, with large variation in humaneness across different methods.
Pest control causes enormous suffering that is largely invisible to the public. Glue board traps immobilize animals who die from exhaustion, starvation, dehydration, or self-injury over 24-72 hours. Anticoagulant rodenticide poisoning causes internal hemorrhage over several days. Snap traps, when properly set, provide relatively rapid death and are among the more humane lethal options. Non-lethal approaches — proofing buildings against entry, removing food sources, and managing habitat — address wildlife conflicts without killing animals. The welfare and ecological costs of indiscriminate lethal control are high, and the efficacy is often lower than prevention-based approaches.
