Neonics are, of course, meant to kill insects, but they are Neonicotinoids are “systemic” in plants. Unlike other pesticides that remain on the surface of treated foliage, these pesticides are taken up by the plant and transported to all tissues – including the leaves, flowers, roots and stems, as well as pollen and nectar. Neonicotinoids (also referred to as “neonics”) are insecticides derived from nicotine. They act by binding strongly to nicotinic acetylcholine receptors in the central nervous system of insects, causing overstimulation of their nerve cells, paralysis and death.

Neonicotinoids are a class of pesticide that have been approved for use in Canada and around the world for many years. In Canada, a thorough human and environmental risk assessment and value assessment was carried out by Health Canada's Pest Management Regulatory Agency (PMRA) before the products were first approved over ten years ago. 2021-03-09
