I feel for you. Here is a link. It works for my driveway ant hills. However 1-2 months later they make a new mound. So I do it again. Check the reviews. Very good. Ortho Orthene Fire Ant Killer1, 12 Oz. https://smile.amazon.com/dp/B000A0UCRG/ref=cm_sw_r_cp_api_fabc_F0pSFbK6JHQGA
Growing up, fire ants were a fact of life. When I bought my house a few years ago, I did a little research and ended up trying out Ortho's fire ant killer. Shit works. I've never had to fight them in an area that anyone actually goes; I'd likely be hesitant to use it near a picnic table for instance. But I don't have fire ant problems at my house anymore. And after using it for two years, I barely get fire ants anymore at all.
