I also love the red rum joke. I personally do not see the massive issue with Ants. I too have had a lot of them outside, red and black. I just give pots a good soaking a few times at first and then a few more over for a couple of days that gets rid of them. Red ants aren't an issue, the best thing to do is not disturb the nest and they wont disturb you.
After researching Ants in the lawn and borders, it is very difficult to get rid of them
