Oxalic Acid Sublimation treatment of our colonies to remove any phoretic Varroa mites.
In this video I demonstrate the ProVap220 Oxalic Acid sublimator which I use to treat our colonies with oxalic acid vapour to kill off any phoretic varroa mites. Phoretic mites are those that attach themselves to the backs of honeybees rather than those found in the cells within the brood nest.
The ProVap220 unit is available from our website www.norfolk-honey.co.uk/provap22
The dose of Oxalic acid dihydrate that I use is 2.25g as suggested in the published scientific paper
