I mentioned that thus far we have used a thymol based paste for our Winter varroa treatment and I must say, that we have been well pleased with the results. Until last year that is, and that was as much our fault as that of this product, but it does highlight one of it’s limitations and that is, it’s efficiency during extremes of cold. We always feed before treating, the thinking behind this being, if you don’t feed you will almost certainly lose your bees whereas, if you don’t treat for varroa, there is still a chance that you bees will emerge in the Spring when you will have a second chance to treat. Anyway, for whatever reason, last year we were late extracting which led to our feeding being later than I would have liked. Sods law dictated that Winter came early in our neck of the woods last year which meant that not only were the bees slow in taking their syrup down but that the varroa treatment was too solid to have any effect.
