I started feeding the bees via top feeder, It is the two quart jar, screened style that sits on the inner cover from Walter Kelley. I saw or read somewhere that putting cinnamon around the feeder will keep the ants away from the syrup. I started feeding about a week ago, This isn't working for me. I sprinkled it all around the feeder and the ants walking righ across. Did I not use enough ? Do I need to build a wall with the stuff ?
