Oxalic Acid is 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 spinach 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.
