Welfare of Ants and Social Insects at Scale

Social insects including ants live in complex societies — their welfare at unprecedented agricultural scale raises questions.

Key Facts

Ants may have a rudimentary form of pain processing based on nociceptor research
Insect colony disruption causes behavioral responses suggesting something like distress
Billions of ant colonies are destroyed annually through pesticide use and land clearing
Some scientists argue that social insect colony welfare should be considered as a collective entity

Welfare Considerations

The welfare of social insects including ants pushes the boundaries of welfare science into philosophically novel territory. Individual ants may or may not have morally relevant experiences — the evidence is genuinely uncertain. But social insect colonies have collective intelligence and behavioral organization that is disrupted by disturbance in ways that parallel individual animal stress. Whether colony-level disruption constitutes welfare harm is a philosophical question without a clear empirical answer. Given the enormous numbers affected and the uncertainty involved, a precautionary approach to massive insect disruption seems warranted.

What You Can Do

Apply precaution when considering large-scale disruption of insect populations
Support research into insect sentience and social insect welfare
Reduce pesticide use that kills large numbers of social insects
Engage with the philosophical frontier of insect and colony welfare
