Humanely managing pest animals while minimizing suffering requires integration of deterrence, exclusion, and targeted lethal control as a last resort.
Pest control often involves causing death or suffering to animals that are simply following their behavioral drives in human environments. The welfare obligation is to minimize unnecessary suffering through the most humane effective methods available and to prioritize prevention over extermination. Glue traps in particular cause prolonged suffering that is ethically unjustifiable when alternative methods are available. Lethal control when necessary should prioritize rapid death over slow trapping methods.
