(I don't use the insert on the SoBB hives) Insert the vaporizer on it and and add two grams of OA (about 1/2 teaspoonful) to the vaporizer from Heilyser, connect the battery and vaporize. Directions are included with the vaporizer and there are lots of posts here regarding it. Do the vaporization 3 weeks in a row & you're set.
    Mines on the way and i'll be vaporizing this week and then i'll see how many mites drop i'm sure the bees will be happy . I'm droping abut 20 a day right now and that up 4x since last week just crazy. glad I have been watching .snl you where right about the fogging not working very well right now was great till first week of AUG. guess that's when things get mitey . I lost all my year old hives{5} last year and 9 more hives by spring so I been trying fogging and now i'm going with OA for the next 3 weeks . My oxalic acid vaporizer should be here buy WED. hope for the best.

    Practise with it in the open air a few times. Time how long it takes to fully vaporize the OA with your particular setup.

    While I understand I dont want to take a big whiff of it , is the general consencus that it is a fairly safe and "organic" method of treatment a fair statement ?

    I had to make up a jumper cable from a 25' extension cord. It's fairly small gauge wire, maybe 16ga. With a small car battery, it takes 3 min. I let it cool down in the hive for a minute, then pull it out and dip it in a jar of water to really cool it off. Then I wipe it out and move to the next. Most object to having something shoved in their front door, others not so much. I've watched through an observation window in a TBH and they don't seem to react much at all.

    Certified Naturally Grown.

    I went back and edited my post to add that.

    edited to add that while I've never bothered to go for certification, I do try to apply their standards.

    Plenty of info here: http://scientificbeekeeping.com/oxal...-1-of-2-parts/


    But do not mess with the dribble method; use the vaporizer. Read Part 2 for the vapor method:

    Probably a dumb question, but are you supposed to remove the supers before you OA vaporize?

    I don't know what other people are doing, but I treat with OA after I remove supers in the fall and then again early in the spring.

    If I use OA it is after I have removed the harvestable honey for the season. The OA I use is 100% OA. Vaporizing is the only method used on the colonies that look like they need it in the late summer/early fall.

    I am glad to hear OA vaporizing can be done with sbb.

    Does the acidic vapour corrode the screen?....break down the white plastic?

    How do you insert the vapourizer? Seems a really stupid question but with my sbb when I poke something into the entrance it hits a board about 1" in.

    If I can get it to work with sbb then I will order a vapourizer post haste.

    This is what I ave gleaned from folks in the know...I am not.

    OA kills phorectic mites on adults...not in the brood. It doesn't harm brood but if you treat when there is brood you need to treat a few times to get the emerging brood with mites.

    Formic acid..MAQS....use once...7 day treatment...gets mites both on adults and in brood...but is greater chance of bee loss, especially newly emergent bees and ones soon to be dead anyway.

    So use OA in late fall when no brood, or use repeat Q 7-14 days.

    Hope I have it correct.
