The hives treated with oxalic acid saw a significant drop in mite count. She said that it would make sense that since people are paying more for the other similar acid, it must be more efficient of less harmful on the bees.
*Formic acid (5 ml of 85%) was applied to record residual mite count Table 2: Effect of Oxalic acid (wick method) on colony strength and stores in Apis mellifera colonies Treatments 2Bee strength (frames) Brood Area (cm2) Honey (g) Pollen Area(cm ) Pre treatment Oxalic acid (Cotton swab method) @ 3%/hive 6.1 402.6 147.3 151.6 The contents of the retort are now cooled to about 80° and a further 50 grams of oxalic acid added.

(2) The action of Heat. The reaction recommences on heating with the formation of aqueous formic acid, which becomes more concentrated with each fresh addition of oxalic acid until the distillate eventually contains 56 per cent. She said that it would make sense that since people are paying more for the other similar acid, it must be more efficient of less harmful on the bees. Oxalic acid Anhydrous sodium sulfate.
