One of my hives has lost their queen. I have a few frames in a nuc with eggs on then I will put this closed up for a few days for them to develop queen cellss and then introduce these frames to the queenless hive. I had used formic pads overe the summer some other Bee Keepers that had used this came out with weak or queenless ives also is their any corrolation between Formic Acid use and weak overwintered hives or is it that Varroa are just to destructive?
