There's a whole lot more then "some" reports out there especially in Europe that show OA to be
benign.
This statement
We DO NOT recommend the use of oxalic

>> made hard chemical mixtures.
almost reads like a conservative play it by the book kind of government regulator speak. like its
not approved by EPA so its damned in the same breadth as home made hard chem mixes.
I know of many beekeepers who have followed the literature and correctly used OA for 2-3
seasons with no signs of problems.
How many have misused OA? I have heard of a few who doubled the amount of OA in solution or
treated 2-3 times during brood season. They figured that 2-3 strips worked better then 1 so more
OA must work better too.
Old habits are hard to kill but its much easier to inadvertently kill your bees.
