Brb4y, thanks for directing me to the Backyard living forums, I never thought about that. Thankfully we do not have the fire ants on our property YET. I did learn that they have infested the school yard that is about 2 blocks from us, so I need to learn more about how to deal with them. About the info I read in the newspaper from the state plant board entomologist who said " fire ants don't like to invade areas which have other species of ant colonies already established," well I told a good friend about this. She told me she had hundreds of sweet ant colonies AND the fire ant mounds, some of which were very big. So, maybe it doesn't matter to them (the fire ants) after all. KC in AR
