Time in Michigan to check for Varroa in your hives and to decide what to do.
If you have not done so, now is the time to check for Varroa. The reason for doing this now is their populations are starting to grow at this time to major levels and drone brood is being reduced so the mites will move on to worker bees causing high mite loads on the workers causing the sudden loss of hives in late fall and early winter.
There is no right way to check for varroa so I suggest using several different ways on each hive. Ether roll, Suggar roll. or the Screened bottom board with a sticky board, checkinf after 24 hours and 48 hours.
Then you can decide what to do to try and eliminate them if your hive has a problem with them. FGMO, FGMO/Thymol, sucrocide, or other chemicals including the strips.
Are we having fun yet?
