Gonna try to kill them. You never really win the battle with fire ants. You think you've killed a mound, and a new one pops up five feet away. About the best I usually do is chase them into the neighbor's yard.

Got fire ants all over Texas, ruined the quail hunting forever. But also have the loner velvet ant/cow ant seen below-not really an ant but looks like one. At nearly one inch long and fairly fat, step on one of these and it is likely to bring you to your knees. They pack one hell of a punch. Worse than a scorpion.
They're also VERY hard to kill. Was in Ft. Valley, GA at a rocket launch and saw one on the ground. Had my Gerber Multi-Tool (Leatherman type device) handy and picked up the little critter with the pliers. Had to squeeze HARD to kill the nasty little bug! Can't kill one by stepping on it with a boot. They're sometimes called cow ants or cow killers, because a swarm of them can kill a cow very quickly when their nest is disturbed.
