Every year, when my plant collection is outside, I seem to get ant colonies in a pot or two. For those into herbs, I've found one, a type of artemisia (wormwood), that ants don't seem to like. I put some leaves in a pot where I've identified a colony and watch them scurry away, carrying off their young. To be completely certain the ants are gone, I soak the pot overnight. During the time when the plants are in the house, I use ant baits (terro) to keep ants from becoming a problem but outside, there seems to be an endless supply of ants so this is ineffective. Good luck getting rid of those ants!
