Aaargh Ants

Ok, so I have an ant problem at my new house. I put out ant baits right after we moved in and it helps a little bit, but I can't even put dishes in my sink without rinsing them immediately. If I don't I have ants all over the place again. We had went to the grocery store last night and got some donuts. Justin must have opened them up last night after I went to bed. He re-shut the box, but when I got up this morning my whole flippen countertop was covered with those nasty little black ants. If anyone has any other ideas on how to get rid of them it would be really helpful. They are about to drive me nuts.
