At our February 5 meeting, beekeeper Brian mentioned the Randy Oliver article about applying oxalic acid dissolved in glycerin and soaked into blue shop towels. This provides a third method to use oxalic acid to control Varroa mites in addition to the drizzle and vapourization methods. Below is the link to the article on Randy Oliver’s website; scientificbeekeeping.com
If you haven’t visited his site before, it is well worth having a look, and also a visit if you are looking for info on a particular topic. Randy has carved a niche for himself where he interprets somewhat heavy duty scientific beekeeping research articles and “translates” them into language more easily understandable to the rest of us. Also, as in this article, he does some simple (small sample size) research on his own colonies.
