Wild Bee Welfare and Pesticide Exposure

Wild bee populations face significant welfare and population-level threats from pesticide exposure. Sublethal effects on behaviour and navigation cause widespread harm beyond direct mortality.

Key Facts

Over 20,000 bee species exist globally, of which honey bees represent only one species
Neonicotinoid pesticides cause navigational impairment that prevents bees returning to their nests
Sublethal pesticide exposure reduces bee reproductive success and impairs larval development
Fungicide-neonicotinoid combinations show synergistic toxicity more severe than either substance alone
The EU banned outdoor use of three major neonicotinoids in 2018 following EU food safety authority review
Emergency authorisations for banned neonicotinoids have been granted in multiple EU countries for sugar beet

Welfare Considerations

Pesticide exposure causes both individual suffering and population-level harm for wild bees. Sublethal effects, which do not kill immediately, may cause more total welfare harm than lethal doses by impairing navigation, foraging success, and reproduction across large numbers of individuals. The welfare of individual bees matters alongside their ecological function as pollinators. Regulatory systems that focus exclusively on lethal dose thresholds miss the broader welfare impact of sublethal chronic exposure. Precautionary restrictions and investment in non-chemical pest management are essential welfare responses.

What You Can Do

Avoid using pesticides in your garden, especially systemic products applied to flowering plants
Support organic farming and buy organic produce where accessible and affordable
Advocate for maintaining and strengthening neonicotinoid bans without emergency derogations
Plant pesticide-free native flowers that support wild bee foraging and nesting
Support organisations monitoring wild bee population trends and pesticide policy
