Every time I add sugar to my hives I get ants. Tried a hive top feeder got ants. Tried sugar bricks got ants. I was hoping the cold weather would be my friend so I tried adding sugar the mountain camp way and three days later, ants. I have successfully used zip lock bags to feed syrup last spring without ants. I get both the little black ants and fire ants. My hives sit on two 4x4’s elevated by cinder blocks. Looking for suggestions.
