Re: Why not use Oxalic Acid?
I'm going to take this opportunity to agree with WLC. I've told the story before...purchased a vaporizer (this was like 10 years ago), used it one fall. I have the thing sitting around and meet someone at the local bee club that is looking for one, I don't need or want mine anymore and it was worth $75 to the beekeeper...seems like a no brainer to sell it to him.
...until we start talking and it becomes clear that he doesn't understand anything...he is planning to vaporize liquid formic acid in the thing. I told him I couldn't find the vaporizer and never sold it to him...I didn't think it was safe for him to have, and I'd rather someone else sell him one if he really wants to try.
Vaporizing and/or mixing OA is no joke. IMHO, selling vaporizers that can't be used legally (especially with the food security awareness/regulations that are coming into play) isn't a joke either...especially if the customer is mislead by claims of safety and effectiveness and not told by the person taking their money that they will be in violation of the law if they use the product. Such a warning/disclaimer seems like a minimum amount of respect and care one can show to their customers.
