Growing evidence for insect sentience is reshaping how we think about the welfare of the trillions of insects farmed for food.
Insect welfare sits at the scientific and ethical frontier of animal welfare. The sheer scale of insect farming — trillions of individuals — means that even small probabilities of meaningful sentience create enormous welfare stakes. Current evidence suggests that some insects have rudimentary pain-like systems, though conscious suffering in the human sense remains scientifically uncertain. The precautionary principle suggests that minimizing unnecessary suffering for farmed insects — through humane harvesting methods, appropriate thermal conditions, and avoidance of chronic stress — is warranted given the scale and the uncertainty. The field is evolving rapidly as insect farming grows.
