Pouring scalding hot water on an anthill usually gets rid of ants. The problem with this method, however, is that the hot water kills any plants that it touches, including grass. So you might get rid of the ants, but you will also have a bare spot in your yard for a long time.

I’ve learned how to kill fire ants successfully by using dry molasses, which is available online and in many garden centers. Heavily sprinkle dry molasses on the anthill, and the ants will be gone in a day or two. I haven’t been able to get rid of other types of ants with dry molasses — only fire ants.

I've had some success with coffee grounds, which will kill any ants trapped in a flower pot with it and will repel the rest. The trouble with coffee is that ants can smell it and hate it. No fire ant is ever going to carry a big steaming lump of coffee down to the queen. I think I might try dried molasses as an alternative.
