Has anyone tried using oxalic acid from a vaporizer to try and kill mites on your dermestids? I recently bought my first package of beetles and here two weeks later I found mites. Not infested but noticeable. I am also a beekeeper and put some Checkmite+ strips in there, but saw some threads on here about the "+" killing or sterilizing the beetles. In the bee yard we stopped using Checkmite+ for the same reason that left long enough could sterilize the queen. We instead use oxalic acid in a vaporizer to kill the verroa mites on the bees. We also use formic acid but its less stable. Just wondering since formic acid seems to work for dermestid mites and verroa mites if oxalic acid would do the same.
