With the discovery of the varroa mites becoming resistant to synthetic (or man-made) chemical treatments, this fact has prompted the kiwimana team to look at alternative treatment methods to keep our Bees alive. We found this new tool for applying Oxalic-Acid crystals, and the kiwimana team are really excited to introduce you to- the “Kiwi Oxalic Acid Vaporizer” !
The “Kiwi Oxalic Acid Vaporizer” is a vaporizer-unit which heats-up. You place the Oxalic-Acid crystals in the head of the vaporiser unit and the fumes are formed from the heat-exchange.
The fumes rise and are then spread by Bee-movement around the Beehive.
The fumes, or smoke, create a kind of ‘dust' which kills the mites by disabling their ability to feed on the bees and they die.
This product designed and built by a Kiwi right here in New Zealand. It's a solid little unit, which will provide years of treatments.
The Benefits of A Oxalic acid vaporizer
- Much Cheaper – 1 grams of Oxalic acid crystals cost around 2.5 cents per application of treatment (1 colony x 4 applications = 10cents)
- Easy to use – you don't need to open the hives to do the treatment.
- Less effect on the bees – unlike dribbling Oxalic acid on Bees, using an Oxalic Acid Vaporizer doesn't cause depressed brood rearing.
- A great addition – to form part of an Integrated Pest Management program
The “Kiwi Oxalic Acid Vaporizer” unti is connected to a 12 volt car or motorbike battery (not included) or a 12volt 7.2amp GEL battery (not included).
The battery – when connected to the unit – heats up the head of the unit which has a space for the acid to be placed in, then the heat converts the acid in to smoke or fumes.
The vapour doesn't affect mites under the capped cells, so we recommend that the treatment needs to be repeated once a week over 4 weeks to cover the full gestation cycle. Thereby enabling the emerging Bees to move through the fumes ‘dust' and the nurse Bees to clean cells and transfer fumes ‘dust' into cells which will have new eggs added.
The “Kiwi Oxalic Acid Vaporizer” is available exclusively from kiwimana.
We also sell Extra Oxalic Acid Crystals, these can be found HERE.
The height of the vaporizer is 10 mm, so if your entrance is smaller than this then you will need to lever-up the front of the hive box with your hive-tool – Do not force your vaporiser through a tight entrance as you may damage the units wiring.
You need to seal the hive to use the vaporizer, so ensure you can block any meshboards or upper entrances in your Beehive (we use an old pillow-case).
The “Kiwi Oxalic Acid Vaporizer” comes with a free 80gram jar of Oxalic Acid crystals for New Zealand Customers.

The Battery We use with our Kiwi Oxalic Acid Vaporizers
We used a Sealed lead Acid Gel Battery, these are very lightweight for moving between hives. The Battery needs to be 12 volt and rated at 7 or 8 amps.
