It was quiet and sunny in the middle of the day here. Only 3 `C, but I`ve decided to give a go a quick mesh floors sweeping, as there were a few hundreds of dead bees in every hive laying on the mesh and obstructing varroa mites to fall through ( If any).Besides I consider hygiene is very important eather. The procedure is very simple and does not require taking off a roof or any BB. I took the whole hive unit off, leaving a floor on a stand. It gave me a good impression – how much stores do my girls have
( All have plenty still) A quick brushing, and unit – on again
Bees did not get bothered much and vast majority stayed in cluster. A smoker was applied of course, in order to crash as little bees as possible when put the unit on again… I think I crashed a few if any.
But amount of dead bees frightening a bit, as I do not see so many in BrianO`s hive above I.e.
(see 2 pictures of dead bees of 2 hives been cleaned)
My clusters look big enough though(as far as I can see through the mesh).
At the moment I have only 2 versions – why so many died :
1) Long term thymol treatment ( about 2 months )
2) Nosema, as I see some faeces on hives outside, and even on the mesh floors of some… not many though
But AFAIK all bees have nosema at a certain degree… And faeces is not an exact indicator of it… It also could be any other sort of their intestinal disorder.
On a landing board of one hive I`ve seen that dead guy (after whole procedure) :
