My bees left/died from SMB and wax moth so I feel your frustration. I put Braggs Apple Cider Vinegar in my hive beetle trap and they attracted a lot of the beetles to it. Then saw the worms thought they were SMB larvae but was told they have red on their heads… I chalked it up to a learning experience and the saga continues. I froze my frames and now will clean them up and start again. I also am trying to find a sunnier location. If I cannot, I am hoping the Nematodes will do their jobs when they arrive.
