If one uses Management Techniques to minimize Varroa, such as scratching capped drone comb every 14 days, is that a "treatment"? Which basically is what Roland does. Is a nonchemical means of control a "treatment"? I would say, imo, technically NO.
Were one setting up standards, like one does for "Organic Farming" associations, I would think that what Roland does would qualify as "Treatment Free Beekeeping".
