i have heard people dust the bees with sugar to encourage them to clean the mites off. there is also a belief that because of poor breeding practices there are now many weak bees and sometimes letting a hive die is for the best. I have learned a lot from a
podcast I used to listen to. I just looked for it and am not finding it. there are a lot of bee keepers here. I just want to keep bees and have read a lot and listened to podcast's on the subject.
