I have two hives that are still getting established both have miller type feeders on them. I also have ants,large black ones about 3/8 of an inch long. That are living between the innner cover and the outer cover. The space is too small for the bees to enter and the ants just fit. Is this something to worry about? The ants aren't entering the hive but they are able to get to the feeder. Once the feeder empties the ants and the bees will meet. If it comes down to a fight between the bees and the ants I expect the bees will win because of numbers but those ants look like fighters
