I have tried many different feeding methods in an attempt to lenghten the time between feedings. I have found that the best I can do is put on a jar of syrup and it is ok for 2 days before it ferments. This is a 2 quart size glass jar. When they are really feeding fast they can drink up the jar in one day. I work full time and this is a hobby for me. Can anyone suggest a way to feed so the syrup lasts 4-5 days? I have heard of using bleach but no thanks, I have tried corn syrup also but it fermented just as fast as the sugar.
