I am looking for an improvement in Fire Ant Control...My goal is to come up with an improved Fire Ant Killer using free (or almost free) stuff.
The best thing to do is to improve the quality of your soil. It is amazing what dry molasses at 15 pounds per 1000 square feet and horticultural cornmeal at 20 pounds per 1000 square feet can do. I can not tell you how many people have had success in eradicating fire ants in this manner. I do not know how much land you are trying to treat, but these two amendments are relatively inexpensive.
I have used just the horticultural cornmeal on mounds and the fire ants have died. They starve to death, so it is not an instant kill.
I do hope you are thoroughly cleaning the chlorine from the utensils before you use them to put stuff on the ground.
thing you need to do is to improve the quality of the soil. When the soil is in good health, the biological activity is improved. Microbes and beneficial nematodes flourish. Fire ants stay away.
