Basically, my question is: what do you do with a queen-less hive that is emptying out, to keep it/ the conditions suitable for re-population?
One of my hives is slowly dying out because of lack of a queen. We tried to re-queen it one time already by merging the existing queen-less colony with another colony. The merged seemed to have been successful, but it has become clear that the hive was again queen-less. (Did the original colony kill her, after all? Was she accidentally squashed during the merge? We don’t know…).
The number of remaining bees in the queen-less hive is now getting so low that I wonder if they will be able to fight of robbers. We might repopulate the hive at some point early this month (September, northern hemisphere) with a surplus colony (caught swarm) of a beekeeper-friend of ours. I am worrying that should robbing start at the hive, that this might cause problems should we repopulate the hive. There is quite a lot of honey and pollen in the brood-box.
