Pest control methods targeting invertebrates raise questions about welfare that require evidence-based approaches to minimize suffering.
Pest control methods vary enormously in the suffering they cause. Anticoagulant rodenticides cause days of internal hemorrhage before death, and secondary poisoning kills owls and other predators. Glue traps trap insects and small animals in prolonged distress. Insecticides often kill non-target insects without welfare consideration. More discriminate methods significantly reduce suffering.
