Update 15 July 2019: A recent study by Toomema (https://doi.org/10.1080/00218839.2018.1486695), suggests that the oxalic dribble can be equally effective if a more dilute solution of OA in water alone (5 g OA dihydrate/1 L water) is applied at the greater rate of 20 mL/comb space of bees, rather than 5 mL. oxalic acid can be made by fusing sawdust (or other forms of cellulose) with a mixture of sodium hydroxide and potassium hydroxide. The “hardest” water contains around 200 mg of calcium carbonate per liter. One possible advantage is that bees don’t like the taste of glycerin, and may thus be less likely to lick up the acid. army294 is waiting for your help. C. 5 3.
