Api-Bioxal Powder – 90%+ Effective Varroa Mite Treatment for Beehives

Target Varroa When Treatment Is Needed: OZ Armour Api-Bioxal Powder

The OZ Armour Api-Bioxal Powder is an oxalic-acid-based treatment for controlling Varroa mites in honey bee colonies. Supplied as a soluble powder, it is available in 35 g, 175 g and 350 g pack sizes, giving beekeepers options for managing different numbers of hives.

Available from OZ Armour, Api-Bioxal is supplied for use according to the applicable Australian permit and label directions. Beekeepers should always check the current approved directions, restrictions and safety requirements before using any veterinary chemical.

Oxalic Acid for Varroa Management

Api-Bioxal contains 886 mg/g oxalic acid dihydrate and is intended for the control of Varroa destructor mites in honey bee colonies. The product is supplied as a water-soluble powder that can be prepared according to the approved application method. (APVMA Permits)

The treatment is particularly relevant when monitoring indicates that intervention is required. Using treatment as part of a broader integrated pest management approach allows beekeepers to combine monitoring with appropriate control measures.

Three Pack Sizes for Different Apiaries

Api-Bioxal is available in:

• 35 g — listed for approximately 10 hives

• 175 g — listed for approximately 50 hives

• 350 g — listed for approximately 100 hives

The actual amount required depends on the approved application rate and colony circumstances, so the current product directions should always be followed rather than estimating dosage from pack size alone. (Beekeeping Gear)

Use When Brood Levels Are Low

The APVMA permit states that Api-Bioxal should be used when the quantity of brood is non-existent or at its lowest levels because oxalic acid does not penetrate wax and therefore does not kill mites inside capped brood. The permit also states that treatment should only be applied when monitoring indicates it is required. (APVMA Permits)

This makes understanding the colony's brood condition an important part of deciding when this treatment is appropriate.

Important Safety and Application Requirements

Api-Bioxal is a chemical treatment and must be handled according to its approved directions. The APVMA permit requires use in the hive and states that it should only be handled in a well-ventilated area. It also instructs users not to mix or use it simultaneously with other veterinary products, including miticides. (APVMA Permits)

For current Australian regulatory information, beekeepers can check the APVMA's registered products and permits database. (APVMA)
