Varrocleaner – Oxalic Acid Vaporizer
A Quality Oxalic Acid Vaporizer at a Reasonable Price! (This is the BEST gift you could give to yourself or your beekeeping friends!!)
The PERFECT Vaporizer for the Hobbyist with a Couple Hives!
The vaporization of oxalic acid in beehives is a proven method of killing both Varroa & Tracheal mites. This vaporizer comes with a removable entrance sealer that also serves to keep the vaporizer from overturning in the hive. Load the cup of the vaporizer with one gram (per brood chamber) of oxalic acid (wood bleach that you can purchase on Ebay or at your Ace hardware store where it labeled as “Savogran) insert it in the hive and connect it to any 12 volt car battery. The vaporization will complete in 2 1/2 minutes. Leave it in the hive for a minute more to seal in the vapors and you’re finished! Disconnect it from the battery, remove the vaporizer, cool it with a wet cloth/sponge & you’re ready for your next hive! If any residue remains in the cup after treatment, scrape it out with a stick or other blunt object.
Oxalic acid vapors only kill the mites that are on the bees (phoretic,) not in the brood. With the hive almost broodless in late fall or early winter, that is an excellent time to treat. If the outside temperature is 40 degrees (f) or above, you can safely vaporize. You want to go into winter with mite-free hives, as the main reasons for winter losses are starvation and mites!
If you need to treat in the summer, you must complete three (3) successive weekly treatments to vaporize the mites that are emerging in the brood. If you’ve supers on, you must also remove or place a barrier between your supers and brood nest. You can use coroplast (plastic sign material) plywood or cardboard as a barrier. You can replace the supers or remove the barrier 3 hours after treating.
In the summer, we open drone brood to decide whether to treat. If the open drone brood contains mites, we treat.
With other treatment methods, you need to purchase them over & over and at substantial cost. With vaporization, you have a one- time cost for the vaporizer and the treatments are mere pennies per treatment!
With a little electrical ingenuity, you can connect several vaporizers to treat multiple hives at the same time.
Note: Unlike some competitor’s vaporizers, there is no glow plug that might need replacing, no additional wires or electrical connections to buy. It is ready to work right out of the box!

No heavy brood boxes to lift, no frames to pry apart. Just insert the vaporizer and treat. Easy, Simple & Effective!
Use appropriate protection as you should not breathe the oxalic acid fumes.
