Countryboy, I guess I should have worded that slightly differently. Canadian beekeepers can't purchase products such as Apiguard and the other thymol product, the one with some thymol and other essential oils that are impregnated in a green wafer. I forget the name of that product. Sure Canadians can purchase thymol crystals and add it to syrup. We don't have the blessing of the governement to do so. Other than Alpha I don't know any research institution that has made claims that thymol in syrup kills varroa. It's kinda like American beekeepers who don't have amitraz in a strip like we do but have been using liquid amitraz for some time now.
