The commercial users of pesticides require an environmental authorisation. If you have pesticides around the house pay close attention to the pesticide container label.

You cannot use it if it is a banned pesticide or past it's use by day. Pesticides with chemical names like DDT, Alumina Dieldrin, Endrin, Heptachlor, Isodrin, Ethylene dibromide, Sodium fluoro acetate (1080), Chlordimeform, Chlordane, Lindane, 2-4-5T and Pentachlorophenol on the container label and SOME products containing arsenic, tin and mercury are banned.
