Today is a dreary and wet day in NorCal (SF area). I took a look at my hives and on one I saw about a half dozen dead or dying bees around the entrance. Two of them had shriveled wings, the others looked normal. I presume this is an indication of DFV and thus mites? I'd treated the hive in the fall with Hopguard and it's the strongest of my three hives, with a ton of bees as of the last sunny day last week. Is there anything I can/should do?
I do have some Hopguard strips left, and also have some MAQS from last year. Forecast is for drizzle and cold for the next week.
