Read something somewhere (as you do) that ants don't like the smell of mint either. I have loads of mint and picked lots of sprigs, crushed them a bit to release the smell, and put it around an area where ants had been busy tunnelling. A few days later they appeared to have "moved on" and I saw no more evidence of earth removal . Don't know if this was a one off or a coincidence, but would certainly give it a go if you grow mint.
