A recommendation (unsure if it's been said already):
Lure them with a small plate of sugar cubes. Should be a pretty thick carpet of them in a short amount of time as they get reinforcements. Once the line/carpet of ants is to your satisfaction, pour some Terro or any Borax-based chem across them. The infected will be sure to carry it on themselves all the way back into the nest.
It's nasty, but effective, and delivery in this method should avoid exposing pets or other wildlife to too much of the stuff.
