VARROX® Vaporizer for Oxalic Acid

Loading reviews...

The ORIGINAL reliable and heavy duty tool. Repetitious accuracy for each evaporation treatment.


Add the required amount of oxalic acid dihydrate to the pan. Place VARROX® through the flight opening underneath the bee cluster. Close flight opening with sponge strips or humid cloth. Attach to 12 V car battery for exactly 2 min 30 sec. Disconnect and remove VARROX®after a while. Dip the still hot pan into a bucket of cold water to cool it down to starting temperature. Seal flight opening for another ten minutes. Best results are achieved on brood-less colonies at outside temperatures above 8 °C.

Treatment profile

Oxalic acid dihydrate is a white powder with high acidity. When evaporated with VARROX®, the fumes will re-condensate as oxalic acid dihydrate on bees and combs. The fine crystal needles will kill Varroa after contact only. Varroa in sealed brood cells will not be affected by the oxalic acid since there is no physical contact with oxalic acid. Varroa mite fall peaks on the second day.

Oxalic acid dihydrate evaporates in two steps and breaks up at high temperatures into inactive vapours. The design of VARROX® allows repetitive accuracy for each treated hive when instructions of use are followed.


Oxalic acid vapours cause irritation of eyes and the respiratory system. Do not use indoors. Always wear protective clothing, Eye glasses and a breathing mask. Always treat your hives with the wind in your back.
