Diatoms will male them move out .

No idea.... There must be some answers on the Internet somewhere.

I have poured boiling water on ground wasps before (at night!) to some good effect. Maybe it will work on fire ants?

Wow, I remember fire ants from when I lived in Louisiana. Another reason I'm glad I don't live there. My ex used Diazinon (I think, it's been 33 years) on the fire ant hills. But yah, it is pretty toxic.

Have you tried Borax all round their nest? It's worth the three bucks that a box of Borax costs in the grocery store.

Fire ants are my nemesis as well! Thanks to comments from other members.

There is an Ortho product named Orthene. It is a white power. Use it very selectively. Find the trails on the ground that the worker ants use to go back and forth to the plants. Sprinkle some of the powder on the trails. The ants will get it on their legs, antennae, and bodies and take it back to the next -- and it will wipe out the entire nest.

Try planting peppers around the garden, also mint. Ants don't.like either of those. I use cinnamon to keep the fire ants away from my bed.

I just did a little research. Diatomaceous Earth sounds interesting. Two resources:

can you grow okra in a pot away from these party animals?
