I seem to have a case of CBPV in one of my hives -- possibly two hives. Black, bald, smaller bees, trembling and 20-30 dead bees under the landing board every morning! Nevertheless, the hive seems strong and productive. I'm sure it is being weakened though and will have a tough time making it through the winter. Does anyone have any experience with this virus? Anything I can do? I did treat with Formic yesterday, but from what I've read there isn't any real treatment. Our mite load has been low.
