Re: Another question on oxalic vaporizing!!
I see some room to get iffy about the use of it in hives. It is approved for use as an insecticide. But in every description it is clearly an insecticide for use in gardens etc. I will go with the "It's not forbidden" angle. I would also not use it on colonies I will be harvesting honey from. Since I plan on reareing queens I am not sure I will have much of a problem.
Significant Minority vs Insignificant Majority, 20% of causes produce 80% of the effects.
