Every summer I get ants tunneling around under my brick patio. They leave piles of displaced dirt around the bricks and I rarely do anything but sweep it away until they tunnel somemore a few days later. After years of this the patio bricks have sunken and settled unevenly. What can I do to stop them from tunneling this year?
