Nosema???

[ty1on]

We had a break in the weather over the week-end and was able to check my hives.   One had the traditional marking on the outside that would suggest nosema.  I opened the reducer and there were hundreds of dead bees on the bottom board.  I cleaned them out and thought that I had a dead out.   The upper deep was packed full of capped honey that they did not touch.  But when I looked in the brood chamber there was a small cluster that was too weak to even resist my efforts.

Should I try to treat with fumiagilin by sraying the cluster?  If so when can the treatment start?

What should i do with the deep that is full of honey?  Can it be extracted or put in other hive?  How can I kill the spores?

They can get the runs trapped inside the hive so long during the winter.  It will clear up when they start eating and flying again.  I would not spray with the cold weather here, only when warm.  And you can move frames of honey anywhere you want with no problems.

There is always yellow snow on a warm day... there are always dead bees on the bottom in the winter.  A cluster that is unresponsive is usually starving (even if there is food nearby).  Some warm syrup directly over or even on the cluster will sometimes get them work up.
