I don't know what kind of ants you have but we sprinkle cornmeal on the mound. The ants cannot digest cornmeal so it plugs them up and kills them. They also pack it down into the depths of the hill for storage so all of the ants are affected. It may take several applications but we have exactly 0 anthills of the 5 rather sizable hills we started the Spring with.I always take one and tack the body down at the street with a sign . . No fire ants here!
It's been several years since I've had a mound in the "people" areas of the property so I has wondering inf there is anything new. Your suggestion is new. Thanks.
I’ve always liked the one about taking a shovel of ants from one mound and putting it on another. The ants start a war and kill each other.Boiling water is another option, did that wen I lived in FL. It may take a couple of applications.
