The VarroCleaner is an excellent option for varroa treatment by means of oxalic acid crystals. The VarroCleaner 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. 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_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.Note: There is no glow plug that might need replacing, no additional wires or electrical connections to buy (unlike other vaporizers). It is ready to work right out of the box!

Use appropriate protection as you should not breathe the oxalic acid fumes.
