What I do to get rid of ants in my lawn is to use a root feeder for trees. I hook up my hose to the root feeder then insert it into the ant hill (about 3-4 inches). I open the cup where you put fertilizer and put in some malathion or other pesticide that mixes with water, close the cup, and turn on the water.ire ants are the hardest ones to get rid of ... they are nearly immune to things that drive away other ants. :(If you have them in your yard, your best resort is to kill them off. They may aerate your soil, but they'll kill plants and harm you and your family and pets with their poison. Fight fire with fire, I say.
