Just got rid of some. They were coming in by a kitchen cabinet in the middle of the house to get to our dog's food.
Used this:
TERRO® Liquid Ant Baits
I just put them down at the point of entry. The ants didn't seem too interested so I put down a thin ring of hand lotion an inch or so wide to corral them in. They won't cross the lotion barrier. Once they got over being disoriented by the dead end chemical trail, they went after the Terro. Took about two days.
