I have one hive that I have been nursing back to heath since about the end of July. This hive has a problem with uncapping sealed brood. For some reason the larve are developing most of the way after the cell is sealed but then dying. And this is very spuratic in the hive. Then about 2 weeks ago I found some Larve that had died. They looked like they had sacbrood but there were just a few of them and they didn't change color at all. And again this was only in little areas of the brood nest. Any suggestions. Are these symptoms I would get if some of the pollen was contaminated with insecticed.Thanks [log in to unmask]
