Sorry, no answers, just more questions!
LOL, well, were in the same boat, hope you brought a fishing pole. I have the beer!
As I understand it... the OA re crystallizes in tiny tiny crystals that cover pretty much everything. It doesnt bother the bees, but the mites are devastated by it. The crystals are on pretty much everything, so long as the bees are not clustered, preventing the vapor/OA from coming into contact with more than the outside of the cluster. The mites come in contact with it because its "everywhere" Including on the bees...
Researching sugar atm, but I will get on this after and see what I can find out for details....
