Wild Rat Welfare and Pest Management Ethics

Wild rats are among the most persecuted animals globally, and their pest control raises significant welfare questions about methods, effectiveness, and the ethics of wildlife management.

Key Facts

Brown rats are considered invasive in most countries where they occur
Second-generation anticoagulant rodenticides cause slow death from internal bleeding over several days
Snap traps, when correctly set, cause rapid death and are considered more humane
Glue traps cause extreme suffering and are banned in several countries
Non-lethal exclusion and proofing methods are effective for building protection without killing

Welfare Considerations

Rats dying from anticoagulant rodenticide experience prolonged suffering from internal haemorrhage before death. Glue traps cause extreme suffering through entrapment and subsequent starvation, dehydration, or stress-induced death. Lethal control methods vary enormously in the welfare harm they cause. Prioritising exclusion and proofing over lethal control, and using snap traps rather than rodenticide or glue traps when lethal control is necessary, substantially reduces suffering.

What You Can Do

Never use glue traps as they cause extreme suffering
Use exclusion and proofing as the primary strategy before resorting to lethal control
Choose snap traps over rodenticide when lethal control is necessary
Avoid second-generation anticoagulant rodenticides due to their slow action and secondary poisoning risk
Report glue trap use in commercial settings to local councils as this may be regulated
