API-Bioxal Powder - Organic Oxalic Acid Varroa Treatment

API-Bioxal Powder - Organic Oxalic Acid Varroa Treatment

Api-Bioxal® Powder is a highly effective oxalic acid treatment designed to assist beekeepers in the control of Varroa mite in honey bee colonies. Suitable for both hobbyist and commercial operations, this versatile formulation can be used in either dribble (trickle) or vaporisation (sublimation) applications, making it a flexible addition to your Varroa management program.

Containing oxalic acid dihydrate as the active ingredient, Api-Bioxal® works through direct contact with phoretic mites on adult bees, helping to significantly reduce mite loads and support strong, healthy colonies.

Available in 35g, 175g, and 350g sizes to suit operations of all scales.

Key Features

• Dual application methods: dribble or vaporisation

• Highly effective during broodless periods

• Suitable for hobbyist through to commercial apiaries

• Trusted organic acid treatment used globally

• Flexible pack sizes for different hive numbers

Directions for Use

Api-Bioxal® Powder can be applied using one of the following methods:

1. Dribble (Trickle) Method

• Dissolve the required amount of Api-Bioxal® Powder in sugar syrup as per label instructions

• Apply using a syringe or applicator at a rate of 5ml per seam of bees

• Gently trickle the solution directly onto bees between frames

• Best applied when colonies are broodless or have minimal brood

2. Vaporisation (Sublimation) Method

• Use an approved oxalic acid vaporiser device

• Apply the recommended dose per hive as per equipment and label guidelines

• Ensure hive entrances are sealed during treatment and for a short period after application

Important:

• Do not exceed recommended dosages

• Typically one treatment per broodless period is sufficient for optimal results

Efficacy

Api-Bioxal® Powder provides excellent control of phoretic mites when used correctly. Oxalic acid does not penetrate capped brood, so treatment timing is critical.

When applied during broodless conditions, Api-Bioxal®:

• Delivers high mite knockdown rates

• Reduces reinfestation pressure within the hive

• Supports colony health and productivity

For best results, incorporate Api-Bioxal® into a broader integrated pest management (IPM) strategy, rotating with other approved treatments where necessary.
