    Question

    Is anyone aware of any research into the use of vinegar for everything that ails the hive?
    A beekeeper from the NW is claiming that vinegar treatments are curing everything from AFB to mites. He has been using this for the last couple of years with excellent success. This is second hand information and I don't have any details, but a large operator is going to do some testing on his hives before he will make recommendations.

    Thanks,
    Mike

    Mike -

    The only thing I've read on this treatment method is a report I received from the Florida Beekeeping group. Be careful of 2nd hand information.

    ----------
    EVALUATION FUNDED BY THE FLORIDA STATE BEEKEEPERS ASSOCIATION
    CONDUCTED BY:JAMES BAXTER, DAVID WESTERVELT & CHARLOTTE RANDALL

    Twenty colonies of honey bees, each with a laying queen and adequate
    stores of honey and pollen, were used to evaluate vaporized vinegar
    as a method for varroa control. All colonies in the study had
    previously been determined by ether roll to contain sufficient varroa
    mites to warrant treatment. Colonies were located near Altoona,
    Florida in an apiary maintained specifically for research. The study
    was started June 20, 2000 and was completed on August 2, 2000.

    The colonies were divided equally into four treatment groups of five
    colonies each. 1) As per label instructions supplied by the
    manufacturer, white vinegar purchased from a local grocery store was
    vaporized using a machine that heated the vinegar and then by means
    of forced air applied it in the entrance of the colony. The machine
    was allowed to preheat for five minutes before treatment began. One
    tablespoon of white vinegar was poured into a receptacle in the top
    of the machine were it was allowed to vaporize for approximately one
    minute before a second and third tablespoon were applied. 2) Prior to
    using the machine with vinegar one treatment group was treated only
    with hot air for approximately three minutes each to determine if hot
    air alone would have any effect on varroa. 3) One treatment group
    received two CheckMite+? strips hung in the brood net for
    comparison
    with an USEPA registered varroa control product. 4) The last group of
    five colonies received no treatment and served as controls for all
    treatment groups. After all colonies were treated a sticky board and
    screen were placed on the bottom board to monitor varroa mite fall.
    Boards were placed after treatment because a part of the hot air
    machine was inserted into the entrance and having the sticky boards
    in prior to treatment would have interfered with air movement within
    the hive. The boards were removed twenty-four hours later and the
    dead varroa were counted. The counts were used as a base line to
    measure the changes in varroa population at the end of the study. The
    colonies that were treated with either the vinegar or hot air only
    were retreated twenty-one days later. At the end of the study at
    forty-two days the CheckMite+? strips were removed from that
    group.
    Also at this time a single CheckMite ? strip was hung in the
    brood
    nest area of all twenty-study colonies. Sticky boards and screens
    were also added at this time. They were removed after twenty-four
    hours and the varroa counts were made.

    As expected the CheckMite+? preformed well with a significant
    reduction in the varroa population. The hot air only treatment and
    untreated controls had a significant increase in the varroa
    population. Vinegar applied as a vapor may slow the rate of
    population increase. This method of treatment needs further
    evaluation before a recommendation can be made for its use.
