BioVet Varrox® Oxalic Acid Vaporizer
1 in stock
This is “One of the highest-ranked models,” and is the one you’ll pass down to your son or daughter. It is manufactured in Switzerland and is now available here on OxaVap! If you have more than 10 hives or just want the very best, this is the one for you. The pan is made of stainless steel, which allows an even and controlled transfer of the heat, thus preventing the overheating of the oxalic acid. Oxalic acid that is overheated decays and builds formic acid and CO2 thus reducing efficacy very fast and significantly.
The vaporization of oxalic acid in beehives is a proven method of killing both Varroa & Tracheal mites. This vaporizer comes with “side” wings that serve 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 or Savogran) insert it in the hive and connect it to any 12 volt car battery. The vaporization will complete in 2 1/2 minutes. Disconnect the vaporizer and leave it in the hive for a minute more to seal in the vapors and you’re finished! Remove it from the hive, DUNK in a pail of water (no need to use a wet rag or sponge (but you can)) & 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. Remember to seal the hive for 10 minutes after you remove the vaporizer to lock in the vapors. Cut pieces of foam work just great.
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!
To treat in the summer, you must complete four (4) successive treatments, five (5) days apart 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.
With a little electrical ingenuity, you can connect several vaporizers to treat multiple hives at the same time.
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 almost pennies per treatment.
