Fire Ants!

We have what are called fire ants here in Tennessee. We have many fire ant mounds out in the fields. We've not had any problems with them until yesterday when Mary stepped on a nest of them and was stung/bit. Mary had a reaction, her face turned purple and she had some welts from the stings and her torso developed bright purple rashes that almost looked like someone had painted purple stripes on her.

Debby calmed Mary down, had Mary wash down in the shower, kept her cool, called the doctor's office, and gave her some Benadryl. Debby then took Mary to the pediatrician's office (I met them there), they checked her out and said she was fine but to keep her cool (no running around outside in the heat) for a couple of days. There were a couple of student nurses (?) at the doctor's office who are working on a paper/study about insect bites and they asked if they could look at Mary, which they did.

So, we need to control the fire ants that are near the house and where the kids play. We prefer a natural/organic method, if you have a suggestion please pass it along. I like the fact that the ants are natural and are aerating the ground but due to the danger we will now need to take some action.
