Best way to kill fire ants

I went to my aunt’s house where she was fighting with ants. It was great fun watching her as a kid. She was taking long time to get rid of it and my aunt was murmuring as if she is going to kill all the ants at a time. That was her anger. As I came in the wrong time, she was unable to talk to me properly. Fire ants are different from wasp or bee stings in that a single worker ant can bite and sting numerous times. The worker attaches to the skin with its mandibles by pulling and then pinching the skin. Then the ant will arch its back slightly and force its stinger into the skin. And now there is no fear of getting out of it as we have natural treatments for fire ant bites that make life simple. My aunt became so happy for giving the solution as fire ants ensure that their ranks are composes of elite capable of destroying any enemy.
