Hi
I lost the Carniolan Queen that i requeened with and was doing so well. I was pretty precautious not to roll her, but maybe, I don't know. I lost in this hive over winter a Queen, and suspected simply disintary. Would Nosema possibly have gotten her? There was a little untidyness on outside of hive coming out of winter. I introduced two frames of brood, (both with really small larvae, but did not see eggs), and am hoping for a Queen cell to emerge. If I don't see one by the weekend I will replace with a Buckfast Italian, as I am blown away by these girls.
My question is, with a new queen coming, should I treat with some Fumagiln-B laced sugar water? Or should I not worry about it?
