Hi guys- Does anybody know if I need a license to spray a dormant oil to kill Wooly Aldegid? (spelling, i know.) I tried the search, but couldnt find anything on this subject. It doenst seem like a real pesticide to me, and I picked some up at the store for the heck of it becuase there are cases very close to me, just getting ready. But, I need to know if I can do this for my business, because I know of at least 1 residence that I could get the job at. Also, what is a better way to spray it than using the cheesy sprayer built into the bottle (you know, the garden hose goes in one end, and the other end sprays). I dont have a license, so I dont have a sprayer. Can I use my pressure washer to get it high into trees? If not I can just advertise for Ornamentals, but I would love to do trees as well. Thanks, Sorry for the long post, Mike PS- If someone could correct my spelling on Wooly Aldegid that would be great too!
