Varroxal – Oxalic Acid Varroa Treatment
Effective, flexible Varroa control for beekeepers of all sizes
Honey bee colonies are under constant threat from Varroa destructor, one of the most damaging parasites affecting honey bees today. Once introduced into a hive, Varroa mites can multiply rapidly, placing significant stress on the colony, reducing productivity, and increasing the risk of disease transmission.
Varroxal is a VMD-approved varroa treatment containing pure oxalic acid dihydrate powder, offering one of the most flexible varroa control options available to beekeepers in Great Britain.
Why choose Varroxal?
-
VMD approved for use in GB
-
Exceptional flexibility – approved for evaporation, water spray, and syrup trickle application methods
-
Suitable for all beekeepers, from small hobbyists with a couple of hives to commercial operations managing hundreds
-
Long shelf life with a resealable container, reducing waste and improving ease of storage
-
Can be used throughout the year, depending on colony condition and varroa monitoring results
Varroxal allows targeted treatment when the varroa action threshold is reached (typically a natural mite drop of 1 mite per day), helping beekeepers maintain healthy and productive colonies.
How to use Varroxal
Varroxal is intended for the treatment of Varroa mites in broodless colonies, where oxalic acid is most effective.
Approved methods of application include:
-
Evaporation (vaporisation)
Commonly used as a winter treatment using suitable evaporation equipment such as oxalic acid vaporisers. -
Water spray application
Varroxal can be mixed with water and sprayed directly onto bees during early season inspections or used for treating swarms during collection. -
Syrup trickle method
Varroxal can be mixed with a 1:1 sugar syrup (one part sugar to one part water) and trickled over the seams of bees, typically as a winter treatment.
Always follow the approved directions for use and dosing guidance.
