Oxalic acid

Oxalic acid dihydrate 99.65% is an approved anti-varroa treatment for organic beekeeping. It should be administered when there is no brood in the hive. This treatment is usually carried out in the fall, around the beginning of November, since it does not kill varroa mites in the sealed brood.

With 100 grams of oxalic acid, it is possible to treat approximately 50 hives.

This product is administered to the hives by sublimation (with a Varrox evaporator ) or by dripping (dissolving in a sugar syrup, using a syringe). Instructions are available upon request from the shop.
