Batteries are not included. The InstantVap Compact works with the following battery types:
Recommended: Use 5Ah or larger batteries for best performance. Available at Home Depot, Lowe’s, or other tool suppliers.
Oxalic acid vaporization is highly effective at killing mites on adult bees — but timing is key. It cannot reach mites under wax-capped brood, so the best results come when the colony is broodless or has minimal capped brood.
Great times to treat include:
These windows give oxalic acid the best chance to reach every mite — helping protect your bees without residue or long treatments.
Q: Does the InstantVap Compact come with a battery?
A: No, batteries are not included. It's compatible with major brands like DeWalt, Milwaukee, Makita, Ridgid, and Bosch. Use 5Ah or higher batteries for optimal performance.
Q: Can I use a Ryobi battery with it?
A: Yes! Just use our Ryobi-to-DeWalt Adapter if you're using the DeWalt-compatible version of the Compact.
Q: What kind of oxalic acid should I use?
A: Always use a registered, beekeeper-safe product like EZ-OX® Oxalic Acid.
Q: Is safety gear required?
A: Yes — a full-face respirator is essential. We recommend the PD-101 Respirator for full organic vapor and particulate protection.
Q: What accessories do you recommend?
A: Most customers also grab the InstantVap Carry Case, and extra plungers for field use. You can browse all accessories in our InstantVap Accessories Collection.

"By far the best tool for a busy beekeeper! I can’t stand cheap products that claim to perform but don’t. This is a rock-solid unit—simple, strong, very easy to use, and fast. Rob is great to work with and truly stands behind what they sell 100%. I highly recommend this product to any beekeeper looking for a reliable tool that gets the job done!"
"I Really like it very much now I can treat my hives with oa very fast and easy this compact model gets job done very quick I am pleased with it I would highly recommend it it’s so easy to clean thank you Lorobbees"
"Twice as fast as my old 110 unit and don’t have to lug a generator around. Did 18 hives on one battery and it still had some charge left in it!"
"So far it seems to be working great. I think any problems I have at the moment is user error and will improve as I get better acquainted with it."
"This product is so easy to use and fast. I am very happy with it and thrilled that I can use my existing batteries on it."
"We purchased the compact unit after having a original instavap but wanting another one as backup called the number on the website not only did I get a real person,Rob himself answered the phone and all my questions and with his guidance I bought the compact unit and it's great faster than my original and I think it is more stable while vaporizing we will never be without a instavap and we will never get one from anywhere else but lorobees great customer service and products. We have between 25 and 30 hives"
"I haven't had a chance to use it yet. My acid will be here today. But it does look nice on the shelf in my office"
"I was blown away by how quickly I was able to cycle through all of my colonies. Because I have both top bars and langs I found the telescoping handle to be a big help with the different hive heights. I'm looking forward to throwing my old OA wand in the trash."
"I use 3/8" openings on my bottom boards cause bee's aren't that tall. This vaporizer is made for 3/4". I did about 30 hives with it and noticed the acid piling up on the bottom board. I called and left a message on how or if I could bend the nozzle to work for me, never got a reply. The machine works but if I had a do over I would find one for 3/8 openings."
