Amdro makes at least two different ant poisons. One for fire ants and the other covers up 12 other type ants. I have both types here and have to use which is needed as they won't interchange.
I am not a pest control guy but have been told one can kill the zillion of ants in a mound with whatever but if you do not kill the queen, the colony will continue, there or they will move. Supposedly, if you don't stir up the colony they will feed the poison sooner of later to the queen, and she dies. But what most don't know is even when the whole colony eats and dies, you can still have new ants hatch, and attempt to keep the mound working. Thus, a second feeding is needed. I constantly have to work my yards every year. I live rural with lots of hay fields and cow pastures and nothing is every done to slow their spread, and the flighty new queens from there consistently choose my place.
