Recommended: Use 5Ah or larger batteries for optimal performance. Available at Home Depot, Lowe’s, or other tool suppliers.
Environmental conditions such as air temperature can affect runtime. For improved performance in cooler weather, consider adding the Silicone Insulation Roof Accessory, which can boost efficiency by up to 20%.

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.

"This vaporizer is awesome! The treatment is super fast, easy to use and very effective. I have been using a m18 5ah battery and I can easily treat my 4 hives with that battery but I will upgrade the the m18 forge 8ah in the near future. Lorobbees is an awesome company with a lot of products, thanks!!"
"Works great and is much faster than before, wish I would have gotten sooner. Only drawback is you need a few batteries, i can do about 5 hives on 5 ah dewalt battery. Could be that my batteries are several years old but just have to have a few charged up ready to go."
"Once it gets going, it’s fine but it takes between 30 minutes and 40 minutes for the unit to heat up to the proper temperature and this is during the warmer months using a 20 V battery. I’ve had this for three or four years and it’s always been this way."
"I haven't used it yet but it looks pretty good"
"Very good and easy to use"

"I love it. It is sooooo much easier and faster than my previous methods!!!"
"Great"
