    Default Oxalic Acid Questions

    I have a few questions about Oxalic Acid that I cannot seem to find the answers too.

    1. How many people use Oxalic Acid?

    2. If you do use it what method do you us for application?

    3. If you evaporate it what equipment do you use and where did you get the equipment and acid crystals?

    Thanks in advance for any responses.

    You might not get too many beeks in the US to reply to that question because it is not legal to use it in the States. However our beek friends across the Northern border can and so use it and it might be coming to the US some time soon (rumor or rumour) has it. Most I think use the dribble method as it is quick and effecive and has less health risk to the human user. You might do a Google on "Randy Oliver" and check out his papers on OA.

    actually if you use the search thing at the top of this page you'll find LOTS of discussion
    here's my homemade evaporator

    as Bob said I think folks are leaning toward trickling

    I found this site very good for both method and concentrations.

    Take care

    I would never trickle OA. I know it is easy and fast, but like the evaporation it kill mites only as long as they outside the cells.

    You should do the trickle method only one time per bee generation otherwise your bees die fast.
    With the OA vaporizer method you can do it as often as necessary without any harm to your bees, brood or queen.

    This time of the year you must treat more than one time when using OA because almost 90% of the mites are in closed cells and breeding.
