I went out to do some pre spring clean up and was startled by some things that I found. I lost 4 small hives and still have two larger hives but I am afraid that the bees might have nosema. (first set of pics) and while breaking down another hive I found a white substance around the dead bees in one frame of one hive and have no idea what it may be. (2nd set of pics) . Any help in identification would be great and if that's not nosema and just normal poop I am fine with that also. Any constructive comments and help with identification and possible treatment is most welcome.
