Insect Welfare and Invertebrate Sentience

The emerging science of insect sentience and what it means for the welfare of billions of insects farmed for food and feed.

Key Facts

Global insect farming produces an estimated one trillion insects annually for food and animal feed
Evidence for insect nociception includes behavioral responses to harmful stimuli and nociceptor-like neurons
Some insects including bees show evidence of negative emotional states and simple learning
Thermal stunning before slaughter is used in some operations but efficacy for insect welfare is uncertain
The moral status of insects remains scientifically contested but precautionary welfare consideration is warranted

Welfare Considerations

Insect welfare is at the frontier of animal welfare science. While the evidence for insect sentience is weaker than for vertebrates, emerging research on nociception, learning, and behavioral responses to harm supports precautionary welfare consideration. Insect farming at scale requires welfare standards even under uncertainty, particularly given the enormous numbers involved. Research priorities include developing validated welfare indicators and humane slaughter methods for farmed insects.
