We just received our copy of a Varroa mite management guide that was produced by the Honey Bee Health Coalition™ (HBHC). This is an extensive and excellent tool written primarily by Dr. Dewey Caron, and it that provides more details than in the one we had produced last year. In particular, they provide more extensive information on each of the chemical treatments available for Varroa control. I highly recommend that beekeepers use both guides when thinking about controlling this key parasite. We have provided downloadable PDF files of the HBHC guide and our IPM guide under our Resources heading.
