Generally, if you can get the ants to move on, then aphid problems also disappear. I often see ants attacking ladybirds which are feeding on the 'herds' of aphids which the ants have carefully moved around to the juiciest parts of a plant. Once the ants have gone, the ladybirds can get on with the job at hand. As already said, a good regular drenching usually does the trick.
