I'm in Louisiana. Fire ants have been a plague here for a long time. I use a product called Bifren. It is not organic. It is not toxic to birds or animals. I broadcast the areas of my yard that doesn't have clover. I treat hills directly in the clover part. Kick over the hill and sprinkle a few grains and the next day the hill will be dead. The reason I don't use it where the clover is because I keep honey bees. Broadcast it will keep the fire ants down all summer. This stuff works better than anything that I have tried. Compared to Ortho or Bayer products it is cheap.
