I have some beautiful noodle beans that are infested with ants. Interestingly enough, they are planted in a bed with peppers, oregano and basil and none of those other plants are affected. The bottom of the plants don't have any ants, but as you look up the vine they are all over the stems and leaves. I keep cleaning them off with water, then spraying with dawn and water and they come right back. Does anyone have suggestions on how to get rid of them?

Thanks, Ginger (10a)
