This is genius .....
Go to Home Depot or Walmart and buy a can of black spray paint, any kind, the cheaper the better, so also try Dollar Store, Big Lots, etc.
Go home and stir up the ant mounds and the area around them with a stick.
Spray 1/3 to 1/2 can on each mound and surrounding turf, covering fairly well.
Once the Ants realize they live in a black neighborhood,
they quit working and start killing each other.
