Neonicotinoids destroy bees’ nervous systems and are banned in Europe, but have been authorised for use every year in the UK since 2021.

Bee-killing pesticides have been found in 85% of tested rivers in England, an analysis of Government figures has found.

Green groups looked at Environment Agency data on neonicotinoid pesticides in river sites tested between 2023 to 2024.

They also found that the proportion of rivers affected appears to have increased from 79% during the testing period of 2020 to 2022.
