Nock, the frames with the dead capped bees presents a problem. The dead bees will become sepsis under the cap. Do not put this septic frame in another hive for the nurse bees to clean up. Scrap off all the wax, add a new insert and save the frame. You can rework the wax if you wish, it?s a lot of work.
In summer you could invite ants to clean up, they do a good job.
