    Hive World supplies Dry Wall Shim for oxalic treatment:

    • Dry Wall Shim for oxalic treatment comes as cardboard strips in bundles of 100.
    • Measuring 38mm wide by 1180mm long – they can easily be cut to provide 3 x strips 393mm long. This gives a cost of 8 cents per strip
    • Soak strips in a solution of glycerine and oxalic acid and hang over your brood frames.  (This is the same method as with regular varroa treatment.)
    • We recommend a 40-60 ratio by volume of oxalic acid powder to vegetable based glycerine.
    • Heat the solution gently to dissolve the oxalic so there are no crystals remaining but take care not to heat it over 60 degrees Celsius.
    • Do not use an aluminium pot as the acid can react with the aluminium.
    • Place the strips in a plastic pail or bin preferably with a lid and pour oxalic mixture over to cover the strips. Leave strips submerged until they are completely soaked through.
    • Remove strips and store until required.
    • Use four strips per brood box and leave for 6-8 weeks.
    • Check strips after 4 weeks as the bees in a strong hive can remove them and they may need to be replaced.
