    Default oxalic vapor

    being new to to bee keeping i do a fair bit of reading and often find the differing opinons confusing and or often can't find the info i am looking for.

    I found some info regarding oxalic dribble method but what about vapor?

    How often can this be used? I typically only read about it being used just before winter so i can draw asumptions from that but i don't want to go on asumptions.

    Any info on what, when and how and why people does with this method is appreciated.

    Thanks

    ok, so to me, a small scale bee keeper, why wouldn't it make sense to use the oxalic acid in vapor form every other week for 3 treatments twice a year

    If i understand this its basically harmless to bees and brood if done right.
    It doesn't build up in the hive or the products removed from the hive.
    It sounds easy on a small scale.
    It is cheap.
    It is effective.
    The mites don't build resistance to it if i understand it right.

    if the varroa has a life cycle that takes about 12 days in the cell then several days (4-12) on adult bees then treating 3 times every 12-14 days should get almost all mites as they hatch out shouldn't it? at the very least knock them way back

    I use the vapor method 3 times, twice a year and will continue. Its fast, effective and cost only pennies each time. I have around 25 colonies and I'm still using the same 7.00 tub of oxalic.

    Hi Guys

    OA solution is much safer,as in not burn yourself or your lungs up. :-) But vapors have a place when the conditions are right and you know what you're doing.

    A few points. I DO think that OA ca be hard on bees, queens especially. I haven't had large kills with it or anything, just my $.02, but I think OA contributed to supercedures. Vapor also requires a good deal more handling caution (albeit readily addressed) due to the inhalation risk.

    But the broader point is that even with a comparatively less-harmful treatment like OA treating according to a schedule (whether they need it or not) can be greatly improved upon by using IPM. Integrated Pest Management means you monitor your mite levels and treat only colonies that need aggressive chemotherapy, and that you use least harmful methods first such as screened bottom boards and drone trapping (the only treatments I've needed for two years now).
