This is my first year, and I've been trying to keep things chemical free, but I am worried... I have one hive that I checked yesterday that has loads of bees with shriveled wings, and I'd say that 10% of the bees I saw in the hive had a mite on their back. I have a screened bottom board and small cell, but this hive is being hit hard it seems to me. I was thinking of doing a powdered sugar shake, but I am afraid that this won't be enough. Can someone give me a suggestion as to what to do??? I am afraid that this colony won't make it through winter... THANKS!
