Insect farming is growing rapidly as a source of sustainable protein. The welfare of farmed insects - particularly black soldier fly and mealworm - is an emerging area with significant scientific and ethical dimensions.
Insect farming welfare presents genuine scientific uncertainty. Unlike vertebrate sentience, the question of whether insects experience suffering in a welfare-relevant sense is unresolved. The precautionary principle suggests treating uncertain sentience with some moral consideration, particularly given the enormous scale of insect farming. Research into insect pain and distress responses is advancing but remains insufficient to draw firm conclusions. High-welfare insect farming protocols focus on optimal substrate, temperature management, and the least aversive killing methods while the science matures.
