Re: What is treatment free?
TF means different things to different people. For most of us, it means not treating the bees for varroa with hope of obtaining resistant bees. To some it means no chemicals, so powdered sugar dusting and drone brood removal is ok. To others that is considered a form of treatment and they won't do it. There are several treatment-free chronicle threads. My advice would be to spend a few hours and read through them. Even the true TF folks don't seem to agree on the best way to be TF.
My sole concession so far is to switch to using OA, a naturally occuring chemical in plants, and giving up the use of Apivar, which is synthetic.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
