It is illegal to buy neonictinoids. If you have any, it is okay to use up what you have. Only farmers and certified pesticide applicators (or people working under their supervision) can apply neonicotinoid pesticides outdoors. See our website for information on the Pollinator Protection Act of 2016. This restricts the sales and use of neonicotinoid pesticides. https://extension.umd.edu/hgic/topics/pollinators-and-pesticides
