He told us that it has been discovered that the Varroa feed on the fat bodies of the bees instead of the blood of the bees like originally thought.What did they say about formic acid? That's what we used.
I have read of people using rhubarb leaves in their hives, since they have lots of oxalic acid.
Our last bee club meeting was about treating for mites. It was presented by one person who is very knowledgeable. I tried to attach a pdf of various treatments, but I don't know if it came through. I can't remember where I found it.
That's Deformed Wing Virus. The wings on the bees don't grow correctly. They can't go forage for pollen or nectar. This is death for the hive if enough get it.
Oxalic acid he said use drench method for 1 treatment and use vapor for the other treatment ( like Spring & Fall). He did say that Oxalic acid is still effective.
My notes about formalic acid aren’t very good. He said Mite away is a form of formalic acid but I didn’t note if it was good or bad. My memory says it was a hit or miss treatment. Works some but not always enough.
He said mites are resistant to Apistan
