Grits or Corn Meal (from fire ant.net)
One person uses cheap corn meal bought at her local discount grocery store. She spreads it around and on the fire ant beds. The workers will carry it into the mound to the queen. When she eats it, it will swell up and kill her.
Another person said: Try grits. A person at the San Antonio Zoo told me that is what they use. It is safe for all other animals but when the ants ingest it, it swells up inside and they can not get rid of it. They also can’t eat anything else so basically they starve to death. We tried it at the Dallas Fort Worth Airport and it really works.
Grits on Steroids (From Steve Molnar):
Here is the method I have used successfully for years. It was taught me by a friend when we lived in Louisiana on 3 1/2 acres by a lake. Cost was a big factor because of the size of the property. We now live in Southeast Texas and I have taught it to all my neighbors and friends.
I take two pounds of fine corn meal and mix it with I cup of sugar and 10 TBS of Orthene Fire Ant Killer (acephate). In a container large enough to hold all of the above, I shake it up really well. On an average mound I sprinkle about 1 TBS, less on smaller mounds. It works great, however it seems to be more efficient in hot weather and I never put it out unless I know it will not rain for a day. In the winter I use Home Defense. My one acre property stays ant free most of the time because I stay on top of it.
