Bee Welfare and Neonicotinoid Pesticides

Neonicotinoid pesticides impair bee navigation, learning, and foraging at concentrations found in agricultural environments, causing colony-level welfare harm even when doses are not acutely lethal.

Key Facts

Neonicotinoids are the most widely used class of insecticides in the world with over 1 billion acres treated annually
Sublethal doses of imidacloprid impair honeybee navigation, reducing foraging success and colony growth
Wild bees show reduced nesting success when nesting near neonicotinoid-treated crops
The EU banned outdoor use of three major neonicotinoids from 2018 following European Food Safety Authority review
Emergency authorizations for banned neonicotinoids have been granted in several EU countries under agricultural pressure

Welfare Considerations

Neonicotinoids at field-realistic doses impair bee cognition and navigation in ways that reduce foraging efficiency and colony survival without causing immediate acute death. Bees that cannot navigate back to hives die stranded far from their colony. Colonies with impaired workers decline gradually as foraging efficiency drops. The chronic impairment of cognitive function in animals that navigate and communicate with extraordinary precision represents a qualitative welfare harm beyond simple mortality counts. Banning neonicotinoids from outdoor use protects both individual bee welfare and colony-level function.

What You Can Do

Avoid neonicotinoid-containing pesticides in gardens entirely
Support organic farming certification that prohibits neonicotinoid use
Advocate for no further emergency authorizations of banned neonicotinoids in the EU and UK
Plant diverse native flowering plants that support bees without pesticide exposure
