Insect farming is growing rapidly as a sustainable protein source, but the welfare status of farmed insects raises important questions that should inform how we produce and consume them.
Insect welfare sits at the frontier of animal welfare consideration. Current scientific consensus holds that most insects are unlikely to experience suffering in ways comparable to vertebrates due to limited neural complexity, but significant uncertainty remains. Some insect species show nociceptive responses, avoidance learning, and potential for basic positive and negative states. Precautionary welfare consideration suggests investing in understanding and potentially improving insect welfare at scale even under uncertainty, given the billions of animals involved. Rapid killing methods that minimize potential duration of any distress are preferable to slow asphyxiation or temperature extremes. The sustainability case for insect protein is strong; building welfare considerations into insect farming from the beginning of the industry is easier than retrofitting them later.
