INSECT FOGGER ISSUE

At one of the recent club meetings we talked about using an insect fogger to apply oxalic acid to the hive.  It has been widely shown on the YouTube internet site.  The oxalic is dissolved in a number of different liquids (water, alcohol, or glycerin) which when vaporized will carry the acid into the hive as a vapor.  While researching the effectiveness of oxalic acid on the control of mites I read an article in Scientific Beekeeping.  This input in an 20 Sept 2017 by a professional chemist indicated that the oxalic powder in either alcohol or glycerin forms non acidic compounds in a relatively short time and will NOT kill the mites.  Here is the article.  If using an insect fogger I would only use water as the dissolving agent.
