Unbroken lines of chalk around entryways will help.
If you don't mind poisons, get some of the ant-stakes, which have the goo inside a box with a small hole, and place them outside. That will one, killl them, and two, train them that food isn't to be found inside.
I put the stakes outside the kitchen door, and within a couple of weeks they weren't coming in anymore. I did that after gallons of boiling water had been poured into the cracks in the patio mortar (which patio they were livig under).
