A 30% solution of OA outdoes every treatment concentration that I have
seen. I hope it was a 30% sugar syrup concentration, but based on the
description, I think not. Plus, the comments on why it was done and the
way it was done are far from anything I have read, and there is plenty
to read about proper methods of application on the web.

Happy to be corrected, but I understand the spray is about 30 grams of
OA to 1 liter (1000 ml) of water and limited to about 3-4ml per frame
side of fine mist from an atomizer, not from a household spray.

The drip method is limited to 50ml per hive and is a sugar solution but
well below 30%. Closer to 5%. Even at those concentrations, there is
harm to bees. At 30%, in a sugar solution, and spraying them in excess
of 3-4ml per side, (all incorrect applications even if OA was approved)
you are weakening them to the point of non-survival.
