When beekeepers get into discussions about controlling mites the discussion sometimes turns to tracheal mites. There are two items of good news on this front. One, most bees in North America have evolved defensive mechanisms so that tracheal mites are no longer a problem. Two, some varroa mite control products also control tracheal mites. Specifically, two fumigant mite treatments, formic acid vapor and thymol, kill tracheal mites. NOTE: The active ingredient of Apiguard is thymol.

This paper had no data stating if oxalic acid vapors also control tracheal mites.
Thanks to Gerard for tracking down this information.
