Oxalic acid sublimation (vaporizing) has become one of the most popular ways of treating Varroa mites in beehives. Insert the vaporizer into the hive entrance and seal the opening with a damp towel. The vaporizer medicates a colony in a matter of minutes and is incredibly economical when compared to other treatments.
This high-quality vaporizer, made in Colorado, was designed by an engineer with dual heating elements to ensure even heating of the oxalic acid. This prevents the oxalic acid from sublimating too rapidly which can cause splatter and reduced efficacy.
