I planted a tree in a big ant den. The soil is so aerated, lol. Don't know if they will kill the tree though..

If you have ant nests already in your growing beds, you may have to sacrifice some of your plants in order to kill the nest. Pouring boiling water on a nest can kill it, but you have to do it repeatedly until the nest doesn't come back. Continually disturbing ant nests may cause them to move out of an area, though they may just build a nest somewhere else. Flooding the nest with a hose might help drive them away. Unfortunately this is destructive to your planting bed as well. Foraging chickens will sometimes dig up and eat fire ants, and armadillos will dig out nests, but of course both these kinds of critters will also wipe out your plants. I wish I had more encouraging things to say. We have fire ants on our place but not many of them. Mostly we try to encourage native ants and other critters that might compete with the fire ants. I'm glad you're determined to not use poison, I think use of poison has only made the fire ant problem worse by killing competitors.
