I decided to not use pesticides on my ant hill. Instead I mixed hot boiling water with Dawn soap and poured it three times on the hill. They I sprinkled powdered Borax on the hill. Next I added hot boiling water with Dawn soap. I hope it works. I don’t see any movement on it now.
I really like Dawn Soap for getting stains out of clothes. I actually works. Just like hair spray works on ink marks.
