Beekeepers Mix #5 – 5kg of Oxalic Acid and 5L of Vegetable Glycerine.

Oxalic Acid is a versatile acid that can be used as a natural control method for Varroa mite in beehives, using the vapourisation technique. It can also be dissolved in sugar syrup at 3.2%.  It is safe to use when the Honey flow is on, and does not affect honey.

Or, it may be dissolved in Vegetable Glycerine at a ratio of 60:40.
