Insect Farming Welfare: Temperature and Humidity Management

Temperature and humidity management in insect farming affects both productivity and potential welfare, with optimal conditions varying significantly between species.

Key Facts

Black soldier fly larvae thrive at 27-30 degrees Celsius with 60-70% humidity, outside which mortality and stress increase
Mealworms are more cold-tolerant but show reduced activity and potential stress indicators at temperatures below 20 degrees Celsius
Commercial insect farming facilities use climate control systems that maintain species-appropriate conditions
Temperature extremes cause thermal stress in insects that may constitute welfare harm if sentience is accepted
Energy costs of climate control are a significant production expense that creates pressure to operate at suboptimal conditions

Welfare Considerations

Temperature and humidity management in insect farming intersects with welfare considerations in ways that parallel conventional animal farming: optimal conditions for welfare and productivity largely align, creating commercial incentives for welfare-appropriate environment management. The key welfare uncertainty is whether insects experience thermal stress as subjectively negative - given uncertainty about insect sentience, the precautionary approach is to maintain species-appropriate conditions and invest in understanding the welfare indicators that could confirm whether interventions are beneficial.
