    Default Questionable Sugar Roll

    This is my first year with bees. I have 4 hives...2) Italians started as packages in April, and 2) Russians started as Nucs in June...all of which are on stands side by side. The other week, during an inspection I decided to do a sugar roll on all hives. 1/2 cup of bees pulled from the brood area and left in the sugar for 5 minutes (I know...statistically wrong) and worst case was no more than 5 mites. All else within the hives looked good...low mite count...all is well. A couple of days later we were supposed to have a cold snap so I slid the IPM boards under the Russians for 2 days. When I pulled them out, one hive had a lot of mites. So I slid IPM boards under all four hives (no time to make them sticky) and left them for 3 days. The result was around 300 mites on 1) Italian and 1) Russian. Thats about twice the "Treat" amount. There were 6 or 7 mites on the other 2 hives. It seems strange to me that #1, there was such a huge difference between the hives and #2, the sugar roll was so inaccurate. What do you folks think? I will be treating the 2) infested hives w/ Formic Acid.

    This is obviously just my opinion, but I would treat all of the hives since they are in the same area. Mite counting is very inaccurate and I would rather fail on the safe side. Are you using MAQS? I haven't been at this long, but they seem to work for me.

    My neighbor used formic acid according to this document and had great results. The gentleman at University of West Virginia who wrote this document attended the local bee club here last Saturday and has revised this method somewhat. But as you can see (or read) his results are pretty good. I understand MAQS is way too strong.

    I'll let you know how it goes.

    Yes they do a VERY nice job of killing mites but queens as well. Make sure to slide the cover a bit off. IMO formic is good in spring to knock off any mites and swarming intensions.

    I used the fumigator per instructions in late august and lost 3 queens out of 20 hives. Those have now requeened themselves successfully. Queen loss would be fatal to the hive at this late date.
    I also used hopguard on some hives that had high mite counts, and a good population of bees but were suffering from pms and had a low amount of brood. After two weeks of treatment the mite count was over 30 on a sugar roll of 200 bees. Maybe the stuff works for some folks but I won't waste my money on it again.
