There are so many questions about pesticide licensing in individual states lately. A couple of years ago, we looked for a way to list all info for everyone, and Jodi found a listing for all state offices. Getting individual answers can often lead in a slightly, or not so slightly, wrong direction. I have put together a page to connect to the proper training and licensing pesticide offices in all US states and territories. Something like this should be locked at the top of this forum to help new members find their way. Here is what is listed on my page Pesticide Regulation in USA States license companies and individuals for application of pesticides for hire. Anything used to control a pest is subject to licensing. PEST (relating to the landscape) = any undesirable plant, insect, disease, animal, or other condition. PESTICIDE = any chemical (natural or synthetic) used to control a pest. Most states have two categories of licensing affecting landscape: one for turf and another for ornamentals. If you only have a turf license, you cannot spray Roundup in the shrub beds. In my state, an unlicensed applicator can be fined $$$ for each INCIDENT. So if an inspector follows you around to 10 properties, you pay 10 x $$$. If he's in a bad mood that day, or you put him in a bad mood, he can probably find 3 regs violated at each site, so you pay 3 x 10 x $$$. Most states have a pesticide regulatory office that is separate from the pesticide training program in the state. To find the pesticide training office for your state, check here: State Pesticide Safety Education Program Coordinators Directory. State Pesticide Regulatory Agencies is a directory of all state regulatory agencies, most with web sites noted. For almost any detailed information about the effects of specific pesticides, visit National Pesticide Information Center. This is the home page for NPIC, a joint communication effort of the U.S. EPA and Oregon State University.
