90%+ Varroa Knockdown, Just 25 Seconds Per Hive
Varroa is now established in Australian beekeeping, and every apiarist needs a reliable, residue free treatment plan. Api-Bioxal Powder is oxalic acid engineered for vaporisation, delivering over 90% mite knockdown in brood free colonies in 25 to 30 seconds per hive, with no residues in honey, wax, or comb.
Available in three pack sizes, 35g (10 hives), 175g (50 hives), or 350g (100 hives). APVMA permitted under PER94609, organic, residue free, with a 5 year shelf life when stored correctly.
How to Use
Vaporisation converts the powder into a fine vapour that settles on every bee and comb surface, reaching mites liquid treatments cannot. Load 2.3g per hive, seal all entrances and vents, vaporise for about 3 minutes, then keep sealed for 15 minutes. Wear chemical resistant gloves, safety goggles, and a respirator, as the vapour damages lungs and eyes.
It can also be mixed with 1:1 sugar syrup for the dribble method, 5ml per seam of bees, maximum 50ml per hive, for those without a vaporiser.
Best Time to Treat
Treat when colonies have little to no capped brood, since it cannot reach mites inside capped cells. Best windows are late autumn or early winter, early spring, or after a brood break (queen caged around 21 days). Monitor mite levels and treat only above your IPM threshold.
Rotate With Other Treatments
Rotate between chemical classes to prevent resistance: oxalic acid, amitraz (Apivar or Apitraz), synthetic pyrethroids (Bayvarol or Apistan), and formic acid (Formic Pro where available). No honey withholding period applies, so supers can stay in place during treatment.
Record Keeping
APVMA Permit PER94609 requires records kept for a minimum of 2 years: treatment date, hive location, amount used, and the applicator's name and address.
Safety Requirements
Wear chemical resistant gloves, safety goggles, and a respirator during vaporisation. Avoid breathing dust or vapours and wash hands after handling. Store sealed in a cool, dry place, no refrigeration needed. Keep away from children, pets, and food or feed. Do not use with other miticides. Maximum 2 treatments per year, at least 5 days apart.
