Pairs well with
A powerful, mid-size oxalic acid vaporizer — compact in form, uncompromising in performance.
The InstantVap 18V Compact is built for beekeepers who need the precision and durability of the Original model, in a lighter, more ergonomic frame. Whether you're treating 20 hives or 60, this unit is designed for fast, efficient, and cordless vaporization with high accuracy and excellent control.
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.

"Works as described and appears to be more durable than I anticipated! I'm extremely happy with my purchase!"
"Will not heat once battery is half low. I went through 3 with just 24 hives. New batteries bought just for machine. Little disappointed it goes through batteries so fast."
"I have seen other units and Lorob, in my opinion, seems to be the best option. I have used my mentors and the bee clubs units. I just received my compact unit the other day and look forward to being able to use my own instead of borrowing. I would recommend anything from Lorob. Their customer service is top of the line and their shipping is fast. I have nothing but good things to say about this company. Thank you Lorob for offering a great product and great customer service."
"Haven't used it yet, but I was totally blown away by the quality when I opened it! Well done Rob and Lori! Well done"
"Have not used it yet. But it was received in a timely manner and well packaged. It looks like it will last a long time if take cared of."
"This is a great unit, my only suggestion is to supply a bent nozzle option for small entrance reducer openings."
"Where has this tool been. Should’ve bought years ago one. Treated 10 hives in 15 mins."
"This unit is very well built, but it’s still overpriced in my opinion. I have used it once and it worked good and fast, except the brass tube at the end, kept getting plugged up with oxalic acid that didn’t get all the way melted into vapor. Anyway, I thought it worked well and way easier than other methods I have used in the past."
"Good quality, well made, everything but the oxalic acid burner stainless. Time will prove the product."
"I was told that a Milwaukee M18 5. 0Ah battery at full charge should be able to treat approximately 20 hives using 4 grams per hive. In my experience, the battery died after treating only 5 hives. Even more concerning, the battery will no longer charge at all. When placed on the charger, it flashes red and green, indicating a battery fault. This battery is only about 6 months old and worked properly before using this vaporizer. A device at this price point should not drain a battery this quickly, nor should it permanently damage a premium Milwaukee battery. I have reached out to the company by email and text and have received no response. The owner has also not returned calls or messages using the contact information provided. Based on the significant gap between the advertised performance and real-world results, the lack of customer support, and the apparent damage to my battery, I cannot recommend this vaporizer."
