I'm with Mike. Drown the little boogers! lol It does work.

Ants are a big problem here. I have found that many of the species here do NOT like to be disturbed. Fire Ants in particular will pack up and move out if you pester them enough. I have discovered that if I lay the entire tree over on its side for a day, and then roll it about 1/4-1/2 of a turn every 24 hours, they quickly get ticked off and leave. My theory is that they build their little tunnels according to gravity and for rain run off. So turning their world upside down destroys their plans. Fire Ants move out in 3-4 days normally, but some other types take longer. 

With all that being said, "An ounce of prevention is worth a pound of cure." I now do my best to keep all pots up off the ground.
