Oxalic Acid & A November Warm Up Saved My Bees/Formic Pro Failed!

I'm fairly certain that I've saved my honey bees from being wiped out by varroasis. Because the Formic Pro formic acid DID NOT KILL ALL THE VARROA MITES IN MY COLONIES! MY BEES WERE DYING! The Oxalic acid I used during the last few days killed hundreds of Varroa mites! By acting now with Oxalic acid, I have slowed the decline of my colonies. My bees will be doing cleansing flights over the few days, as temps will be in the 40's. I stand a good chance now of ZERO winter losses again!
