How our vaporizers for oxalic acid works

The oxalic acid treatment is suitable for use in organic beekeeping. The powdered oxalic acid is heated until it is vaporized. The oxalic acid vapor forms microcrystals that kill it in contact with the varroa mite. Instead, these crystals are well tolerated by bees. There are two types of vaporizers, with slow vaporization and fast vaporization, and we produce them both.

Slow vaporizer models

They are generally preferable and in any case more suitable in the cold months, when the claster of the bees is contracted. With these vaporizers the cup into which the oxalic acid is placed is inserted into the hive. The heat produced by the cup and the greater vaporization time allow the cluster to open and the treatment reaches its maximum effectiveness.


it is the most appreciated model  by beekeepers who have up to 70-100 beehives. Vaporization is slow but unlike the BASIC model it is equipped with temperature control. Thanks to the temperature control it is possible to insert the dose of oxalic acid with the hot cup. The advantages of slow vaporization are maintained and it takes less time (40 seconds to dose 1 gram and 1 minute and 30 seconds to dose 2 grams of oxalic acid)

Fast vaporizer models

When the game gets tough and beekeeping becomes a profession, every beekeeper is faced with the “time available” problem. Every professional beekeeper knows when the time is right to administer oxalic acid and make it effective even with fast vaporizer systems.


With its 300-360 Watts of power, the temperature control and the specially designed and insulated boiler can administer oxalic acid passing from one hive to the next without pauses. The vaporizer retains the ability to vaporize immediately after the previous vaporization has just ended. The straight diffuser tube is very rarely obstructed and is available in two versions: short, for treatment from behind; long, for treatment from flight opening. The vaporization time is 10 seconds to administer 1 gram and 20-25 seeds to administer 2 grams of oxalic acid.


This vaporizer completes all the features of the PRO Easy model with the addition of a semi-automatic dosing system. The beekeeper chooses the doser suitable to his needs (from 1, 1.5 or 2 grams), fills the tank with about 45 grams of oxalic acid and is ready to pass from one hive to the next without having to continually manipulate the oxalic acid in powder.
