I have been keeping bees for three years now and have two colonies. When harvesting honey I have always used porter bee escapes to clear supers without any problems, until yesterday! Two weeks ago I placed a wet super over the feed hole on one of my hives for the bees to clean up, after a week it was dry but still full of bees, so I put another wet super underneath, a crown board with two new porter bee escapes on top then the dry super. Yesterday I went to take off the first dry super and to my horror discovered a couple of hundred dead bees on the crown board, all was well below. There were some dead bees in the escapes. Can anyone shed light on where I went wrong?
