I'm considering getting my commercial applicator's license for pesticides in Pennsylvania. My question is about something I found while doing research. I found this quote on the PSU website. To become certified as a commercial or public applicator, you must pass two written examinations (Core and Category) and be employed by a pesticide application business. Does this mean literally you have to be employed by an existing business? Therefore prohibiting someone from starting their own business. Thanks for any imput you can give me.
