After mixed concerns about top feeders, I am trying some 5 qt pail feeders with 1/16 holes drilled in the lid. I placed them on top of the hole of the inner cover, then a deep box around them with telescoping cover on top. I don't seem to have any ants in the brood box but there are always a lot of them around the pail. Is this something to be concerned about? Wiil the bees take care of the ants if they try to enter the brood area?
