Oxuvar 5.7% is a concentrated solution to be mixed with water for spray applications to honey bee hives against varroa mite. Oxuvar is available in two pack sizes (275g or 1kg) depending on the number of hives to be treated. Approved for use in the UK by Veterinary medicine Directorate (VMD).

When is best to use?

Broodless colonies as Autumn/Winter and/or spring/summer treatment.

The problem: Varroa mite (Varroa destructor) is an increasing problem in UK honey bee hives. This bee parasite lives on the bees and within the hives feeding on the bees. Attack from varroa mite can weaken bees making them less able to do their job and support the colony, it also makes the bees more susceptible to disease. Hives with significant infestation levels of varroa will produce less honey, be in poorer condition and are less likely to survive through winter. 

The product: Oxuvar 5.7% can be mixed with water and used as a spray application for autumn/winter and/or spring/summer treatments against varroa mite when temperatures are above 8°C.

How to use:

Spray applications of Oxuvar 5.7% should be made to broodless colonies whilst outdoor temperatures are above 8°C. Oxuvar 5.7% is prepared into a ready-to-use 3% oxalic acid dihydrate spraying solution.

1. Open the sealed container and add the required amount of tap water:

• Add 275 g sugar to the 275g Oxuvar bottle
• Add 900 ml to the 1 kg Oxuvar bottle 

2. Close the container and shake well.

3. Fill hand sprayer with required volume of solution.

4. Apply a maximum of 80 ml per hive (2-4 ml over each side of the comb which is covered in bees).

Note: If during the winter application period cooler temperatures are being experienced (below 8°C) a trickle application of Oxuvar 5.7% may be more suitable.
