Has anyone considered combining this oxalic acid treatment with the FGMO treatment with a fogger? I don't want to open up "old wounds" but Mineral oil treatment with the fogger only takes about 5 seconds per hive. I've been using it for the first time this year and have not had a mite problem. Its said to kill the tracheal mite also. I wonder if you could dissolve the acid in the mineral oil and weather it would damage the fogger? It would be a lot quicker then the vapor method. (A paper by Dr. P. Rodriguez about FGMO treatment can be read on www.beesource.com)
