InstantVap 18V Turbo Oxalic Acid Vaporizer

InstantVap® Turbo Oxalic Acid Vaporizer

The fastest cordless oxalic acid vaporizer for beekeepers: about 10 seconds per 2 g dose and about 20 seconds at 4 g, on the DeWalt, Milwaukee, Makita, Ridgid or Bosch battery your crew already carries.

The Turbo is the InstantVap built for sideline and commercial apiaries, $550, rated 4.9/5 by 50+ beekeepers. It sublimates EPA-registered oxalic acid through the hive entrance and cycles fast enough that a crew can treat a 100-hive yard in a morning, and the display counts hives so nobody loses their place down a row. It is the unit we run in our own yards for the fall treatment series. Made in Hungary; sold, serviced and covered by a two-year warranty at Lorob Bees in Baltimore, MD.

🐝 What it does in the hive

Oxalic acid vaporization is a varroa mite treatment for honey bee colonies. The vaporizer heats 2 to 4 grams of oxalic acid dihydrate until it sublimates; the vapor fills the hive, recrystallizes on the bees and the comb, and kills varroa mites riding on adult bees while leaving the bees, the brood and the honey essentially untouched. Oxalic acid is registered by the EPA for this use and is labeled for use with honey supers on. Use only an EPA-registered product such as EZ-OX.

🔑 Key features for the bee yard

• About 10 seconds per hive at 2 g, about 20 seconds at 4 g. The Original and Compact take 25 and 45 seconds; in a large apiary the Turbo saves hours per treatment round.
• Cordless, on your own battery. DeWalt 20V, Milwaukee M18, Makita 18V LXT, Ridgid 18V, Bosch 18V or Metabo HPT 18V, chosen at checkout. Use a 5Ah or larger pack. No generator, no cord, no compressor in the bee yard.
• Cycle counter. The display records the total number of hives treated and the number treated on the current battery, so a crew working down a row of colonies never loses its place.
• Dynamic temperature control holds the sublimation temperature steady from the first hive to the last, for a consistent dose in every colony.
• Tool-free adjustable dispenser, 1 to 4 grams, so a single deep and a double deep get their own dose without stopping.
• Stainless-steel body with a low, replaceable brass stem that slides into the hive entrance without tilting the unit.
• Battery protection with built-in over-discharge cutoff.

📋 Quick facts

🚜 Built for big yards

At about 10 seconds a dose, the time per hive is the walk between colonies, not the vaporizer. The hive counter on the display keeps a crew's place down a row, a 6Ah pack covers roughly 40 hives at 2 g in mild weather, and the 5 lb EZ-OX bucket holds more than 1,100 doses at 2 g, which puts the acid cost near a dime a hive. No propane, no generator, no cord. The Treatment Series Planner builds the schedule for any hive count, and Lite vs Compact vs Original vs Turbo shows where the Turbo earns its price.

📟 The display, in beekeeper's terms

• Shows the working temperature and the battery voltage.
• Temperature adjustable from 446–500°F (230–260°C), switchable between °F and °C.
• Total hives treated, and hives treated on this battery.
• Warns when the battery is discharged.

The status LED is readable in full sun without bending down: slow blink while warming up, steady when ready to treat the next hive, fast blink while the acid is sublimating, double blink when the battery is spent.

🧪 When to vaporize oxalic acid

Oxalic acid reaches mites on adult bees, not mites sealed under capped brood. A single treatment does the most work when the colony is broodless: mid-winter, after a swarm or package is hived, or during a natural or induced brood break. With brood present, beekeepers run a spaced series across a full worker brood cycle so mites are caught as they emerge, which is exactly the job the Turbo's speed and cycle counter are for. Our Treatment Series Planner builds that schedule for your hive count, and our Broodless Window Finder estimates when your colonies are most likely broodless.
