Cricket Welfare in Insect Farming: An Emerging Field

Crickets are among the most commercially farmed insects globally, raising welfare questions as the evidence for insect sentience grows.

Key Facts

Global insect farming for food and feed is expected to reach 1 million tons by 2030
Crickets are the most widely farmed insect for human consumption, particularly in North America and Europe
Evidence suggests crickets have nociceptors, show avoidance learning, and exhibit stress-related behaviors
Current farming methods involve high-density housing, cold stunning, and freezing as the predominant kill method
Scientific consensus on insect sentience remains uncertain but the probability is non-trivial according to recent reviews
The scale of insect farming — potentially trillions of individuals — makes this a high-priority welfare research area

Welfare Considerations

The welfare of farmed crickets exists in an area of genuine scientific uncertainty. Unlike vertebrates, whose sentience is well-established, invertebrate consciousness is debated. However, recent research showing pain avoidance, wound-directed grooming, and stress responses in insects suggests some form of aversive experience may be possible. Given the astronomical numbers of insects farmed, even a small probability of morally relevant suffering represents an enormous total welfare impact. The Rethink Priorities insect sentience project and similar efforts are developing frameworks for insect welfare improvements in farming contexts.

What You Can Do

Support organizations researching insect sentience and developing farming welfare standards
Advocate for evidence-based insect welfare guidelines when engaging with insect protein companies
