I just looked up the brochure. Im not trying to scare you or anything, but from what little I read, and what little I know, that approach will take a long time with lots of losses to achieve. There are lots of Beekeepers who are treatment free, Michael Bush comes to mind, but, that being said, I think he would tell you it was a long road. My goal is to one day be treatment free. Doesnt happen overnight if you want bees in the spring is my guess. Maybe that conference will have local queen producers that will up the odds. I would be interested to know. Good Luck and enjoy. G
