I think those that have responded have been much to hard on Dr. Rodriguez at least he is trying SOMETHING what have you all OFFERED....NOTHING I see WE (including myself) are all waiting for the silver bullet to come from SOMEWERE human nature as it were always seems to look for the flaws or the reason it WON'T work I say BE THANKFULL someone is trying to help. I think a person should use t-mite resistant stock without oiled paper and then go from there otherwise you just keep treating with "oil" for tracheal mites when Br. Adam has proven you do not need this step for T-mite we must conquer Varroa then we will be on the right course and my point precisely is that Dr. R has tried something and may have a lead. Jim Maus
