I have used vinegar before, wash everything with white vinegar. If you know where they are coming in you can also draw a link across there path with kids chalk. They won't cross the line. This works good outside before they come in. If you locate their home turf (mine was between the patio stones) boil the kettle and pour the boiling water on the nest. You will be left with nothing but ants with their legs up in the air trying to do the backstroke.
