I have lost several hives this winter that seem to be caused by nosema apis. I know there is no definite cause unless I get it tested. But from everything I know, it looks like nosema. In my research I cannot find any information on how to handle the frames and their contents that are soiled. I have cleaned the top bars with my hive tool as much as possible but I know the spores with still remain to some degree. Do I just put them away and wait for warmer dryer weather and add them back to hives or use for splits? Don't want to kill more hives with recycled spores. Also, any input on best way to prevent it?
Thanks in advance
