I live on the Pacific Coast of Mexico, tropical climate, exotic flowers. My garden has been overtaken by ants of all types, first leaf cutters-- horendous, but seem to have gotten rid of them, then various non-aggressive types. But for some time now red ones, about 1 cm long, have begun making nests under the centers of plants, digging the dirt up into a hill easily 2 feet above ground level. You can't hardly see some of the plants! I have used all locally available options; the most favored were granules placed into the nest, but all that happens is they relocate a few feet away. One area has "Luz de Bengal, " which has several shoots per plant and is so infested that I feel I may have to dig up all the plants. I would REALLY appreciate your help!
