Perhaps because it isn't a issue ?I already google and found nothing focused on this subject.
I'm surprised you took so much notice of that particular TF rant, which he starts off by stating: "As the use of acids has increased so have queen events" - without a shred of evidence to support this. Even if this should be true - correlation ought never to be confused with causation.My attention to this aspect emerged after reading this: "As the use of acids has increased so far, there are major events now, especially among the acid vaporizing crowd. There is a big reason most commercial operations requeen 60% or more of their apiary in any year…" in one of the comments of this post https://honeybeesuite.com/using-oxalic-acid-vaporization-when-brood-is-present/. From what I have read so far I have seen nothing to support this opinion but may have escaped relevant information.
