Black soldier fly larvae are farmed at enormous scale for protein production. While the welfare status of insects remains debated, precautionary standards are emerging to address potential suffering.
The welfare status of black soldier fly larvae is genuinely uncertain. They possess nervous systems but their capacity for subjective experience of pain or distress remains unresolved. Applying a precautionary welfare principle to billions of farmed individuals is prudent given this uncertainty. Best practice focuses on avoiding unnecessary harm: appropriate density, temperature management, and humane harvesting methods. The enormous scale of production means even small individual-level welfare improvements aggregate to significant total welfare effects.
