I had to use a product called Terri. It was available at my local grocery. Just follow directions. They consume the stuff, take some back to the nest & it wipes out the best. These were the big black ants usually found outside on trees, etc. My neighbor swears by peppermint oil on the point of entry.
Buy packaged cornbread mix that says it is sweetened and put it where they are. They will take it to the mound, everyone will eat it and die, they can't digest the cornmeal, but will take it because it is sweetened. Little goes a long way.
I spray and that keeps them at bay, but I know they are still in there...eating away, populating and doing whatever little ants do because they occasionally come out ...

The product is called Terro. Sorry for the misspelling.
Baby powder works great too. The scent messes up their pheromone trail and they can't digest it. They take it home too feed their family
I read somewhere dryer sheets repel them, I have not tried it myself. I used corn meal on their trails. Have not seen any since.
Diatomaceous earth. Sprinkle it on the places where they are entering.
But use the food grade, not the pool grade. You can get it at Tractor supply and most farm and garden stores.
This has worked for me.
