About the OxaVap ProVap 110 Oxalic Acid Vaporizer

OxaVap ProVap 110 Oxalic Acid Vaporizer

The OxaVap ProVap 110 Oxalic Acid Vaporizer runs on 110 volts of AC electric power. It comes with a standard 3-prong earthed plug. Beekeepers using this oxalic acid vaporizer can use a car battery and an inverter to power it. This is however only necessary when your beehives are located far from the house or main power outlet. The consumption rating of the vaporizer is 250 watts or 2.2 amperes. It does not require you to have a compressor for it to work.

The vaporization temperature of oxalic acid is 157C. This is easily reached by the OxaVap ProVap 110 Oxalic Acid Vaporizer. It comes preset to a temperature of 230C, which is higher than the vaporization temperature of oxalic acid. It allows the vaporizer to quickly vaporize oxalic acid crystals. A red sequence readout on the vaporizer displays ‘230’ when the preset operating temperature is reached. The display is very handy in informing beekeepers that it is ready for use.

The vaporizer weighs 4 lbs and measures 13.25 x 10 x 4 inches.

Using the OxaVap ProVap 110 Oxalic Acid Vaporizer

Using the OxaVap ProVap 110 Oxalic Acid Vaporizer is an easy and simple process. Once you have connected the vaporizer to a power outlet, allow it to heat up. Next, add some oxalic acid to the cap. Attach the cap to the vaporizer cup while holding it upside down. To start vaporization, turn the vaporizer right side up. The oxalic acid will fall onto the sublimation plate of the vaporizer and get sublimated. Oxalic acid crystals work very well with this vaporizer.

Using the OxaVap ProVap 110 Oxalic Acid Vaporizer you are able to move from one beehive to the next very quickly. This is because the vaporizer does not need to cool down once it has been heated up. Once the beehive has been treated, you only need to turn the vaporizer upside down, remove the cap, and refill the acid cup with oxalic acid. You can then move to the next hive where you turn the vaporizer right side up when ready to treat the hive. This makes the vaporizer very suitable for those with many beehives.

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.

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 the 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.

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?
