Only thing I’ve had that worked against argentine ants was termidor sc. Non repellent, and slow kill time. Spray it on an active walkway, and it will slowly spread through the colony and kill them all off. Again, supercolonies, so it isn’t a perfect solution. But it’s the only thing that works for me for 6+ months at a time. Then, I have to spray again as soon as I see another Argentine.
