  1. Add 1 gram per full sized box of Oxalic Acid crystals to the head of your Kiwi Oxalic Acid Vaporizer. We use a 1/4 of a teaspoon, check your crystals with scales to ensure this is correct for you.
  2. For example colony with two full sized boxes requires 2 grams for treatment.
  3. Insert vaporizer into hive, either from the underneath the meshboard (if you can seal it) or from the front entrance.
  4. Seal any ventilation with cloths.
  5. Connect your vaporizer to the power source (12 volts) for two and a half minutes (Maximum)
  6. Disconnect power source.
  7. Time a further ten minutes
  8. Removed all cloths and remove vaporizer.
  9. Ensure vaporizer is cooled down before reusing or storing.

Whats next

If you have brood repeat these steps every week for three weeks, a total of three treatments are required, as the vapour doesn't effect mites in the capped brood cells.

If you have a bloodless period then only one treatment is required.

After the treatments, Do a mite count, check results to ensure the treatment has worked correctly.

Always store Oxalic Acid crystals in a dry air tight container, if it gets damp it will not vaporize correctly.
