Neonicotinoids are a group of chemical used as a pesticide on crops. In fact, they're so effective at killing pests, they're currently the most widely used insecticide in the world.
These chemicals target the nervous system by mimicking the actions of nicotine, a natural plant toxin. They block signals between nerve cells, causing paralysis and death.
However, a study commissioned by the International Union for Conservation of Nature has concluded that these neonicotinoids also are deadly to many beneficial creatures – from earthworms to sparrows - and have even been linked to the decline of honeybees.
Graihagh Jackson visited the RSPB’s headquarters in Bedfordshire to speak to Dr David Gibbons, one of the authors of the report.
Neonicotinoids are without doubt powerful pesticides and the link to Bee problems has come up time and time again.

Goes in my mind, particularly Australia , it certainly can kill them like flies!!!
