Black soldier fly larvae (BSFL) are increasingly farmed as sustainable protein sources, but welfare standards for insect farming lag behind the scientific evidence on invertebrate sentience.
Insect farming welfare sits at the frontier of applied animal ethics, where commercial scale meets genuine scientific uncertainty about sentience. BSFL farming involves conditions - heat, density, substrate quality - that may or may not constitute welfare-relevant experiences. The scale of insect farming means that even if the probability of sentience is low, the expected welfare impact of improved practices could be substantial. Thermal killing methods that achieve rapid loss of responsiveness are considered more welfare-conscious than methods involving prolonged temperature stress. Industry leaders have begun developing welfare guidelines, recognizing that proactive welfare standards are preferable to reactive regulation.
