Hi, I wanted to let you know the way we get rid the leaf cutters. natural remedy we use is warm water with a small amount of sugar (a few pinches to 1tsp depending on amount you are making), mixed with yeast. Once the yeast is active we pour or spray it on the ants, they take it back into the nest and it corrupts their food cultures. This is rather invasive to their nests but harmless to us. This is not an instant fix and could take a week or 2, we apply it a couple of times for a week and just wait. However you should know that they keep away fire ants so once the nests are killed keep an eye open for fire ants building nests. Good Luck.
