There is one type just for "regular" ants that we use. Haven't seen the fire any stuff yet because the jug we bought is 2 years old and still working strong, It doesn't take that much to be effective. Just a pinch or two on each hill. They may have a new one for fire ants. I'll look at Wally World and see. We live in the desert and have lots of ant hills that disappear with this stuff. Used it on our 9 week RV trip last year also.
This stuff really is like candy to them and then they're dead. Once you drop it on an ant hill, the next day, no more ants come out to play, Big ants, small ants, it doesn't matter.
