Baygon!

Traveling tip: Should you decide to come live in Rome (which I recommend), consider bringing ant traps. Sugar ants, as it turns out, are not merely a North American species. Both times I have been here (which I know is a rather small 'n') we have shared our apartments with ant friends. Rome, of course, also sells ant poison. It's called "baygon" but either it is not very effective or I can't figure out how to use it correctly.
