When mowing with our 54” deck, I turn the deck off, lower it, drive over the mound, shaving the top inch off it. Then back up and watch them come pouring out. Raise the deck to normal cutting height, turn it on, drive forward with the left of the three blades over the mound. After being batted around by the three blades casualty rates are high.
If after first shaving the top off the mound, one sees it has exposed a layer of larvae, I simply go back and forth over that with a front tire, turning it and mad ants into slightly muddy texture.
Also, one can take a flat shovel, shave the top off, quickly spray the surface and saturate the holes with engine starting fluid, then quickly put the dirt that was shaved off back on top, patting it down some to help seal in the ether.
But, actually, I think they are going to own the south sooner or later.
No, crazy ants will make trouble for them.

They have no way to stop crazy ants.
