Bob,
Thanks for your comments relating to Formic and a perceived resistance
against its ability to damage varroa mites.

I noted that you also mentioned mites being resistant to OA.

Do I take it that the same general comments you penned about Formic acid
     may "count" for OA?

It would be a good thing to actually know why Formic /OA kill the mites
was definitely known. A higher degree of certainty of whether resistance
  may result from the knowledge.

High or low pH. seems to be a deterrent to life processes if the
organisms are not tolerant to such. Then, there are bacteria that thrive
in environments that would seem to defy "the norms for life" - those
that make a living around hot vents in seismically active areas.
