Farmed Insect Welfare Considerations

The rapid growth of insect farming for food and feed raises important welfare questions about the sentience and suffering of billions of individuals produced each year.

Key Facts

Global insect production exceeds an estimated trillion individuals annually and is growing rapidly for protein and feed markets
Common farmed species include black soldier fly larvae, mealworms, crickets, and locusts
The scientific consensus on insect sentience is genuinely uncertain — some researchers argue for precautionary welfare consideration
Insects show nociception and avoidance responses to harmful stimuli, but whether this involves subjective experience is debated
Welfare concerns in insect farming include stocking density, temperature stress, CO2 and chilling stunning methods, and slaughter
The UN FAO notes insect farming requires significantly less land, water, and feed than conventional livestock per unit of protein
Regulatory frameworks for farmed insect welfare are emerging in the EU but remain undeveloped in most countries

Welfare Considerations

Farmed insect welfare sits at the frontier of both scientific understanding and ethical consideration. The sheer scale of insect production — trillions of individuals — means even a small probability of morally relevant experience translates to a potentially enormous welfare concern. The precautionary principle suggests that improving welfare conditions costs relatively little and could matter enormously if insects do experience something. Advocating for research into insect sentience and supporting the development of welfare standards for insect farming is a prudent and low-cost action for animal welfare advocates.

What You Can Do

Support research into insect sentience and the development of evidence-based welfare standards for insect farming
When purchasing insect protein products, prefer companies that publish their welfare standards and practices
Advocate for regulatory bodies to develop insect farming welfare frameworks alongside other farmed species regulations
Share information about insect welfare uncertainty to encourage thoughtful decision-making in the food industry
Support the development of humane slaughter standards for farmed insects based on the best available evidence
