Oxalic Acid Crystals are used in many ways, in the fight against the “Varroa Destructor Mite” – which feeds on the Bees abdomen fats – similar to a tick on a sheep. The mite travels on the Bee into the hive, then enters brood-cells, once the cell is capped it feeds on the larvae and pro-creates within the cells.
Drone cells are most common-place to find infestations – check out our “Drone Management Frames“.
Oxalic acid is naturally found in many plants such as members of the brasssica family and Rhubarb whose leaves contain about 0.5% Oxalic acid.
It can be used in conjunction with our “Kiwi Oxalic Acid Vaporizer” (which, with heat-exchange, creates a smoke vapour within the hive) or also can be mixed with sugar syrup and dribbled on the bees in Autumn.
Note: Consult the Varroa book for more information about these methods which are noted as acceptable treatment methods approved in New Zealand.
The Oxalic Acid we sell, is in a crystalised form and is 99% Concentrated.
It comes in Jars of 80 grams or 200 grams.
