Oxalic acid vaporization is a highly effective method for controlling varroa mites — especially when applied at the right time. Like any treatment, its success depends on colony conditions.
Oxalic acid targets mites that are riding on adult bees, but it can’t reach mites sealed under wax-capped brood. For this reason, it works best during periods when your hive is naturally broodless or experiencing a temporary brood break.
Ideal times to treat include:
These windows give oxalic acid vapor a clear path to nearly every mite in the colony, making treatment far more effective and helping your bees thrive.
Q: Does the InstantVap 18V come with a battery?
A: No, batteries are not included. The unit is compatible with major-brand batteries including DeWalt, Milwaukee, Makita, Rigid, and Bosch. We recommend using 5Ah or larger batteries for best performance.
Q: Can I use a Ryobi battery with InstantVap?
A: Yes — we offer a Ryobi-to-DeWalt adapter that works with any of our DeWalt-compatible models (Original, Compact, or Lite). Just make sure you're using the DeWalt version of the vaporizer.
Q: What kind of oxalic acid should I use?
A: Always use an EPA-approved product like EZ-OX® Oxalic Acid, which is pre-measured and safe for use in beekeeping.
Q: How long does it take to treat one hive?
A: Each treatment takes about 25 seconds. The InstantVap is one of the fastest and most efficient vaporization tools available.
Q: How many hives can I treat per battery charge?
A: This depends on the battery and dosage used. For example, a 6Ah DeWalt battery can treat up to 22 hives using 4g doses, or up to 44 hives with 2g doses. See the full dosage chart above for more estimates.
Q: Is safety gear required?
A: Yes. We strongly recommend wearing protective gear when vaporizing oxalic acid. Our top choice is the PD-101 Full Face Respirator, which offers full organic vapor and particulate protection.
Q: What accessories do you recommend?
A: The InstantVap Carry Case is a popular upgrade — it protects your unit during storage and travel, keeps your gear organized, and fits batteries, oxalic acid, and accessories. You can also add a Silicone Insulation Roof to increase efficiency in cooler temperatures, and our Ryobi Adapter for added battery flexibility.
