One of my hives has been overrun by wasps. It was one that I had recently added a new queen to, and she had started to lay.
But too late. There were not enough bees to defend the hive and the queen has now disappeared, presumed dead.
I have moved the frames with brood and a couple of frames of brood from another hive into a nuc box, together with the remaining bees. The nuc box has two small entrance holes, so is much easier to defend.
Maybe they can make a new queen from eggs on the frames.
