More about choosing a vaporizer

↑ Back to the products

An oxalic acid vaporizer heats oxalic acid dihydrate until it sublimates into a vapor that fills a closed hive and kills varroa mites on the adult bees. The InstantVap is an entrance vaporizer: the nozzle goes in at the front, the hive stays shut, the bees stay calm and you stay out of the vapor. A 2 g dose takes 10 to 30 seconds depending on the model, then you walk to the next hive with no cord, no 12V battery to carry and no pan to cool down.

Four models, $349 to $550: the Lite for backyard apiaries, the Compact and Original for 20 to 60 hives, and the Turbo for sideliners and commercial yards. All four have an infinitely adjustable 1–4 g dose and the DeWalt, Milwaukee, Makita, Ridgid, Bosch or Metabo HPT battery socket you choose at checkout. Rated 4.8 to 4.9 stars across 500+ verified reviews. Or let the InstantVap Sizer pick the model for you.

Cordless replaced corded, and we would know

We used to build corded vaporizers ourselves. Before the InstantVap, Lorob Bees made the 120V Original and the front-entrance Macro, and we still stock parts for them for the people running ours. We stopped making them because the battery units are simply better at the job.

A corded vaporizer tethers you. There is a 12V battery to carry down the row, leads to drag and untangle, a pan to heat up and then cool down before you move on, and a working radius set by the length of your wire. None of that is a hardship on four hives in the back garden. On forty, it is your whole afternoon.

A cordless unit runs on a power-tool pack you probably already own, delivers a 2 g dose in 10 to 30 seconds depending on the model (20 to 90 seconds at 4 g), and you simply walk to the next hive. That is the entire reason the category moved. If you are weighing a cheap corded unit against a cordless one, weigh it in hives per hour rather than dollars.

Not sure which one? The InstantVap Sizer asks how many hives and yards you run, which tool batteries you own and how you treat, then names the model, the batteries to carry and the acid you'll need for the season.

Two things left to decide

Entrance or top. These are entrance vaporizers: the nozzle goes in at the front, the hive stays closed, the bees stay calm and you stay out of the vapor. Top-bar vaporizers mean cracking the lid on every treatment.

How fast, and how many hives. Time per treatment decides whether a yard takes a morning or an afternoon. Most beekeepers run a 4 g dose on a full-size colony. At 4 g, the Lite takes about a minute and a half per hive, the Compact and Original about 45 seconds, and the Turbo about 20 seconds. Across 40 hives that is roughly an hour on the Lite, half an hour on the Compact or Original, and under fifteen minutes on the Turbo — before walking time.

The four models compared

ModelPrice2 g dose4 g doseBatteryWho it's for
Lite$34925–30 secondsAbout 1 min 30 s3 Ah or largerA backyard apiary, up to about 20 hives. The lightest and least expensive way in.
Compact$445About 25 secondsAbout 45 seconds5 Ah or larger20–60 hives. Same heating power as the Original in a smaller, better-balanced body, with spare plunger storage in the handle.
Original$495About 25 secondsAbout 45 seconds5 Ah or largerThe proven full-size workhorse, with the deepest accessory catalog.
Turbo$550About 10 secondsAbout 20 seconds5 Ah or largerSideliners and commercial yards. Cycles fastest between hives, with a screen that shows battery voltage and a treatment counter.

All four take an infinitely adjustable 1–4 g dose, carry a two-year warranty serviced in the USA, and are built for one battery socket that you choose when you order. Cycle times are for a warmed-up unit; add 50–60 seconds for the first heat-up from cold.

Will it run on the batteries you already own?

Almost certainly. Every InstantVap is built for one battery socket and you choose it when you order: DeWalt 20V, Milwaukee M18, Makita 18V LXT, Ridgid 18V, Bosch 18V or Metabo HPT 18V. No proprietary battery, no charger to buy, no cord to drag down the row. The Lite is happy on a 3 Ah pack, the size that comes with most drill kits; the Compact, Original and Turbo want 5 Ah or larger. On Ryobi or Craftsman? We make an adapter for Ryobi and one for Craftsman V20 that run a DeWalt-socket Lite, Compact or Original — we don't recommend either on the Turbo, which pulls more current than an adapter is happy with.

What else you need

A vaporizer on its own isn't a treatment. You also want EPA-registered EZ-OX oxalic acid and a full-face respirator — oxalic acid vapor is an irritant and a dust mask is not enough.

Questions beekeepers ask before buying

Which oxalic acid vaporizer is best for bees?

It depends on how many hives you treat and how fast you want to move. Up to about 20 hives, the InstantVap Lite is the sensible buy. From 20 to 60, the Compact or Original cut the 4 g cycle to about 45 seconds. Past that, the Turbo's 20-second cycle is the difference between a morning and an afternoon. All four use the same entrance method, the same 1–4 g dose range and the same EPA-registered oxalic acid.

Do I need a special battery for an InstantVap?

No. Every InstantVap is built for one power-tool battery socket that you pick when you order: DeWalt 20V, Milwaukee M18, Makita 18V LXT, Ridgid 18V, Bosch 18V or Metabo HPT 18V. The Lite runs on a 3 Ah pack, the size that comes with most drill kits. The Compact, Original and Turbo want 5 Ah or larger. There is no proprietary battery and no charger to buy.

How much oxalic acid does a vaporizer use per hive?

The EPA label for EZ-OX allows up to 4 g of oxalic acid powder per deep brood chamber. We recommend starting at 2 g per brood box, so a single deep gets 2 g and a double deep gets 4 g, and stepping up to the full 4 g per box for a heavy infestation. Use EPA-registered oxalic acid such as EZ-OX; it is legal to treat with honey supers on.

Is a cordless vaporizer worth it over a corded one?

We built corded 120V vaporizers for years and stopped because the cordless units are simply better at the job. A corded unit tethers you to a 12V battery and a cable, and the pan has to cool before you move. A cordless InstantVap delivers a 2 g dose in 10 to 30 seconds and you walk to the next hive. Weigh the two in hives per hour rather than dollars.

What warranty and service comes with it?

Every InstantVap sold by Lorob Bees carries a two-year warranty, and we are the US service center for every model, so post-warranty repairs, plungers, nozzles, o-rings and adapters all come from our shop rather than from overseas.

InstantVap vaporizers are designed and built by InstantVap (instantvap.eu) in Hungary. Lorob Bees is the US seller and the US service center for every model.
