Oxalic Acid Vaporization

We do not recommend OA vaporization.

  • It is very dangerous to breath. You MUST wear a special chemical respirator.
  • It requires many sequential treatments to be effective.
  • It does not penetrate into capped brood, where much of the Varroa is.
  • It should be applied at dawn or dusk when most bees are in the hive.

The [[Oxalic Acid Dribble]] method is much more effective and does not require multiple, sequential applications.
