Black soldier fly larvae (BSFL) are increasingly farmed as a sustainable protein source, but their welfare needs careful consideration as insect sentience research advances.
Whether black soldier fly larvae experience suffering in any morally relevant sense remains an open scientific question. Their nervous systems are far simpler than vertebrates, yet some researchers argue caution is warranted given the scale of production. Current welfare science recommends maintaining optimal temperature, humidity, and density conditions - which also happen to maximise production efficiency. Slaughter method research is nascent; freezing prior to grinding may be more humane than direct grinding of live larvae. As insect farming scales up, precautionary welfare standards are increasingly proposed by welfare scientists even under uncertainty.
