While Oxalic dribbling of 50mls of a 3.5% solution of Oxalic in sugar syrup (which would be 35grams of Oxalic in a 1-litre bottle of sugar syrup) is one way to go, why not take advantage of powdered sugar. They are in the perfect container to apply the sugar, and one can rotate the package, shake the bees around, and otherwise make sure everyone gets exposed to the poofs of 5-micron sugar dust. The free sugar is not going to hurt them at all, as they likely need sugar, and would be encouraged to stay in the hive and get used to their (depending on package transport time, perhaps very!) newly-added queen. ******************************************************* * Search the BEE-L archives at: * * http://listserv.albany.edu:8080/cgi-bin/wa?S1=bee-l * *******************************************************
