Hello Bee-Lers ! I quit agree with Stan : If your brood box(es) are big enough to keep the queen egg laying IMO it's better to use a queen excluder : clear wax, no queen thus no problem to remove the bees with excluder (2-3 hours and then blowing). IMO it's important, mostly since the use of Apistan, to not mix the frames = brood frames (contaminated with fluvalinate) and honey super frames (IMO: as clear as possible : the mine are never more than 5 y old) Sorry for my very poor english ! I had very little time ! Jean0-Marie <[log in to unmask]>
