Hi chris,
Firstly, the ants are not eating the aphids. They stimulate the aphids, who in turn secrete a honeydew substance which the ants farm off of them.
Washing-up liquid diluted with water, is a very good non-chemical solution to the green/black fly problem. Spray this on all the leaves. I was going to suggest ant powder to stop the run, but if you don't want to use it, I can understand.
