I agree that Boiled feet aren't very permaculture, but neither is using borax. In fact, from a permaculture standpoint, I wouldn't even recommend trying to kill the ants unless they were fire ants and posed a threat to people or pets but since these are black ants, personally, I'd just leave them. Most ant colonies die off during the winter and if you want to encourage that, then the best thing to do is find their major food source and remove it or plant sage, pennyroyal, peppermint, rue, mint, bay, lavender, marigolds, pyrethrum, wormwood, yarrow or tansy to encourage them to abscond from their nest.
