Thanks for the correction on the OA vaporizer - I was getting a translation from Russian to Romanian to English, so ',amy a slip between cup and lip'...... These beekeepers buy OA in 9 gram tablets which can be broken into 3 gram sections and placed in the vaporizer. They are adamant about the temperature control being precise. I have seen several using old Russian army surplus gas masks - full face coverage - for protection, which makes for an interesting fashion statement, but they seem satisfied with the protection. They are still using fluvalenate here and claim it is effective - yesterday I talked to a large beekeeper who is burning fluvalenate/amitraz strips in his hive entrance to smoke the bees, with what he claims are good results. We got zero mites on 3 alcohol washes so something is working.
