Flying Ants

I have red ants in the front lawn. When I first moved here, it was new build and the turf was level with the slab path. Now after forty plus years, in places along the edge of the path, the turf is two to three inches above the level of the path, purely from red ants shifting the soil around as they seek to warm their eggs in the summer sun, and I constantly hit little new built hummocks elsewhere when I mow. They are a pain in more ways than one.
