Try instant grits. Put about a teaspoon on the mound, it works for

This is silliness. Ants eat grain all the time and it doesn't kill them. Your
grits may drive them away, but not for the reason you think. That's sorta like
claiming that you shouldn't throw rice at weddings because birds eat it and
die when it expands in their stomachs.
