Common feeding of syrup has some draw-backs that need to be considered. Bees sharing common feeding may spread some diseases, particularly Nosema, from colony to colony. More contamination, however, probably occurs from bees drifting into the wrong hive. Common feeding does not always provide equal food to each hive, and weak colonies may not receive enough of the food. The bees can only access syrup in the open in fair weather, and some of the bees being fed are from feral colonies or distant bee yards. Common feeding of syrup can encourage robbing behavior, and entrance reducers should be used to give the guard bees an advantage. Fumagillin, a treatment for Nosema disease, should not be applied in common feeding, because it is broken down by the sun.
