Description
Tablets are to be used for the Vaporization Method only.
Use Oxalic Acid Dihydrate when little or no brood is present as Oxalic Acid Dihydrate will not control Varroa mites in capped brood and may damage bee brood. Repeated applications can be made when colonies are raising brood, though this may be less effective than needed for complete mite control during the brood-rearing season.
Oxalic acid can be used when honey supers are on the hive.
Oxalic acid is used to treat colonies during low brood periods, packages, or swarms. This product can also be used as a “clean up” Varroa treatment following the application of a different acaricide where Varroa infestations continue to be problematic.
VAPORIZER METHOD:
Note: Two (2) grams of Oxalic Acid per Deep Hive Box is the maximum legal dose with the Vaporization Method.
For use with 1 gram tablet or as a powder.
Apply only to outdoor colonies with a restricted lower hive entrance. Seal all upper hive entrances and cracks with tape to avoid escape of Oxalic Acid vapor. Smoke bees up from the bottom board. Place 2 grams of Oxalic Acid Powder or 2 1g tablets per deep brood chamber into the vaporizer. Follow the vaporizer manufacturer’s directions for use. Smoke bees up from the bottom board. Insert the vaporizer apparatus through the bottom entrance. Apply heat until all Oxalic Acid has sublimated.
