Using Oxalic Acid

Oxalic acid has proven to be an effective treatment for the control of Varroa mites and thoracic mites in honeybee hives. Left unchecked, these parasites can cause serious damage to a honeybee colony. It leads to deformed wings in the colony and can eventually lead to loss of the entire colony. In heavy infestations, the colony absconds from the hive. Using oxalic acid is one option that beekeepers may employ (click here for more) to avoid these losses with one or two treatments per hive every year.

Pros and Cons


  • The tool vaporizes oxalic acid quickly. It reaches its operating temperature in a short time. The temperature does not drop too low during vaporization.
  • You do not need to open up the hive to treat your beehives for Varroa mites. This vaporizer works very well via a small hole drilled in the back of the hive. It helps beekeepers avoid placing hot elements in beehives.
  • By allowing beekeepers to work from the back of the hive, the vaporizer causes minimum disturbance to bees. This is unlike other vaporizers that require you to work from the front of the hive at the beehive entrance.
  • The vaporizer is relatively light and compact. It is easy to move around between hive treatments. Stowing it away for storage does not eat up too much of your space.
  • Upon purchase, the vaporizer comes ready to use. It requires no additional assembly by the beekeeper. It comes with an oxalic acid measuring spoon as a bonus. The vaporizer also comes with a spare cap in case you lose or damage one.


  • Where your beehives are located far from your house or mains power supply, you require additional equipment to use the vaporizer. You will need a battery and an inverter to power the vaporizer.
  • This vaporizer requires you to drill an additional hole in your beehives. The hole then needs to be covered up once you are done treating the hive.

  2. Recommended working temperature for ProVap110 is 230°C (446°F). Oxalic acid sublimates between 315°F(157°C) and 372°F (189°C). Above this oxalic acid decomposes to formic acid and carbon monoxide. Is this a probem?
