Ok, I am sure once I ask this everyone will respond with use the search option. But I have done that and read until my eyes are almost bleeding and still has not answered my question. Anyway, I have a small lawn maintenance company and alot of my customers have been asking me if I spray for Bag worms or Tent worms. I have never done any type of fertilization or used Pesticide besides good old round up. Wont do anything I am not licensed for. So my question is this, what type of license do you need to use chemicals such as Liquid Sevin, Orthrene, or any of the other chewing insect chemicals? I know every state is different so this question is sent out to the knowledgeable New york Pesticide applicators. Thxs for your help.
