  • Oxalic Acid [OX / OXA]


Complete instructions provided. Directions are to be followed exactly.

35 grams.

Oxalic Acid is a natural acid used for treatment against varroa mites in early Spring or late Fall when little or no brood is present or swarms. This treatment only kills the phoretic mites, or those mites on the bees. It will not control mites in capped brood.

Applications are for outdoor use only.

This is enough to treat 20 colonies using the direct dribble method or 35 colonies with the use of a vaporizer. 


Currently NOT approved for use in California.

Due to shipping restrictions, oxalic acid cannot be shipped internationally or by air. 


When performing an Oxalic Acid Dribble, use the following recipes when mixing your solution:


Oxalic Acid (g.)

Hot Water (g. or fl. oz.)

Sugar (g. or cups)

20 Hives

35 grams

600 g. or 24 fl. oz.

600 g. or 3 cups

10 Hives

17.5 grams

300 g. or 12 fl. oz.

300 g. or 1.5 cups

5 Hives

8.75 grams

150 g. or 6 fl. oz

150 g. or ¾ cup


Even if you only need enough for 1 or 2 hives, use the 5-hive recipe and discard the surplus. It’s hard to accurately mix tiny quantities.
