Triazicide is supposed to be the "next generation" insecticide after

Most likely, treatment with insecticides or boiling water kills a lot
of ants but the remaing ants, including the queen, just move a few
meterts away and start a new colony. In the US, S. invicta has evolved
a behavior not seen in their home range. They may have several
interconnected mounds with multiple queens. Killing one mound is a
temporary fix at best.
