Why Europe Banned Three Neonicotinoids from Outdoor Use
The European Union banned the outdoor use of three neonicotinoid insecticides considered dangerous to pollinators. A look back at a major decision for biodiversity.
It is one of the most significant environmental decisions taken at European level: banning the outdoor use of three insecticides in the neonicotinoid family because of the risks they pose to bees and wild pollinators.
- Imidacloprid
- Clothianidin
- Thiamethoxam
Why these substances are a problem
Systemic insecticides
Neonicotinoids are absorbed by plants and spread through all their tissues, including pollen and nectar. Pollinators are therefore exposed even when they are not the intended target.
Effects at low doses
Scientific studies have identified effects even at low doses, including disorientation in foraging bees, weakened colonies and reduced reproduction.
An issue that goes far beyond honey
The decline of pollinators directly threatens the production of fruit, vegetables and oilseeds. It is part of a broader collapse in insect populations documented by numerous European studies, with several overlapping causes: pesticides, habitat loss, monocultures and climate change.
The European ban did not solve everything. Debate continues over exemptions granted to certain sectors and the substances used as replacements. But it set an important precedent: ecosystem health can take priority over agro-industrial interests.
- Three neonicotinoids are banned from outdoor use in the EU.
- These insecticides contaminate pollen and nectar, exposing bees even outside the targeted crops.
- Protecting pollinators is a global food-security issue, not merely a beekeeping concern.
