    I use OAD as my last treatment of the season, end of November - beginning of December. I have not had any issues. Follow Randy Oliver's directions. I would suggest using a food scale to be accurate with the measurements.

    Some commercial folk I know who used it did so in 40-50f range with no problems. They did not let it get cold....

    May I ask why OAD and not OAV, you built that sweet vaporizer(and I mean that honesty).

    msl, think you got me mixed up with someone else. Don't have a vaporizer and have only 5 hives at this time so drip isn't much of a hassle. If I add any more I'll definitely be vaping.

    I prefer checking for remaining available feed and adding more on days well below freezing if the wind is not high. Come middle of February, I will be in all my hives but when its not snowing or blowing too hard.

    Also (per the beek): if a mite Tx is needed now, it can be done -- even an oxalic acid drip would be fine. I'm assuming the liquid itself s/b fairly warm, since it'll be placed onto the bees, and why bother 'em with cold fluid on a cold day? I didn't have the chance to ask about Tx temps.

    Any observations, opinions, warnings or support for these? Thx much .....
    I agree with old-time beek.

In Britain the traditional time for oxalic acid treatment (drip) has been Christmas. https://www.youtube.com/watch?v=psuAswYFSG4
    In preparing pallets of hives for transport I have taken honey off of hives with six inches of snow on the ground and more falling. You should have seen the bees clustered on top of my head and on my shoulders. Those hives did quite well in FL a few weeks later.

    I would be very interested to see any scientific paper saying that mortality of bees after OAD is 30% or anywhere near that figure.

    OAD is easier, faster, and more effective than OAV. And safer to you.

    Not true. Read the Sussex study. With a ProVap vaporizer and a proper respirator, one can safely treat hives much faster than dribbling.

    OAD takes one minute per hive

    OAV has to be done, at least what the BeeSource beekeepers tell me, at least 3-10 times per hive, which means 3-10 visits to a apiary, each visit(=driving to and back) taking some time plus time of treatment

    I last year did a single OAD on all hives and double on some hives after harvest, and still had 60% winter losses. It is definitely easy, fast, and inexpensive. In my one year experience I would declare single and double applications of OAD a waste of effort. Maybe triple and quadruple applications might work more effectively. I did not see any bee mortality on the 150+/- hives I treated with OAD. But since it was so ineffective in reducing losses I doubt it had much mortality on mites either.

    Worst thing about OAV is having to shave so the respirator gets a good seal. Having a clean shave in cold weather isn't fun

    OAV with the ProVap takes 20 seconds per hive. If doing it during the broodless period, one treatment.

    OAV is still prohibited here if what the commercials tell me. Because of the danger to the beekeeper. But the bee clubs now started to use it with an experienced member treating all hives in round because they see the advantage. So there must be an advantage.
    If a commercial working for two generations of beekeeping tells me something like that Im rather in the mood to believe him.
    You will meet him in Austria and may ask him to this. I will translate.
