Insect Farming Welfare | Animal Welfare Hub

The emerging welfare questions around insects farmed at scale for food, feed, and other purposes.

Key Facts

Insect farming for protein is growing rapidly, with billions of insects reared industrially
Scientific consensus on insect sentience remains uncertain, particularly for pain and suffering
The precautionary principle applied to welfare uncertainty suggests some minimum standards are warranted
Black soldier fly larvae, mealworms, and crickets are the most commonly farmed insects
Killing methods including chilling, grinding, and heating have different potential welfare implications
Regulatory frameworks for insect welfare are largely absent in most producing countries

Welfare Considerations

Insect farming welfare sits at the frontier of welfare science, where the precautionary principle must be applied thoughtfully. The balance of evidence suggests insects are less likely to experience pain in a morally significant sense than vertebrates, but this is not a certainty. For insects farmed at the scale of billions of individuals, even a small probability of morally relevant suffering creates a responsibility to minimize potential harm. Research into insect sentience and welfare is expanding rapidly, and the insect farming industry has an opportunity to develop welfare standards proactively rather than reactively as evidence accumulates.

What You Can Do

Support research into insect sentience that will help resolve current uncertainty about their welfare status
Engage with insect farming certification bodies developing welfare guidelines under the precautionary principle
Choose insect protein from producers who engage transparently with welfare questions
Advocate for inclusion of insect welfare research in animal welfare funding priorities
Follow the developing scientific literature on insect sentience and welfare as an informed consumer
