SMH. No.
Those damn ants were FAR worse 40 years ago when I moved in here, and the last couple years I’ve had trouble with the read sugar ants instead ... NOT a fire ant in sight at presnt, and the AMDRO has stayed on the shelf.
There ARE basic factors at play here that works against the type of thing you propose, and sans evidence, you’re spitting in the wind. I can’t exactly account for WHY the fire ants here have not been much a problem, BUT, we have had several cold winters IN SUCCESSION.
Maybe it was FR where I read that fire ants can’t tolerate “crazy ants”. (a smaller, hyperactive ant).
I don’t know how to advise someone on importing “crazy ants” , but they’re definitely preferable, as they don’t bite. (A minor nuisance, by comparison).
Another method, was shown to me in Florida by a New Yorker.
He simply stood over a mound with RAID ant & roach spray and nearly emptied the can. The mound never recovered.
Here in NW Florida we have Caribbean ‘Crazy’ Ants, that drive out fire ants. First named by a Texas Exterminator.

Crazy Ants look just like normal ants, and they do bite but not like fire ants. They are called ‘crazy’ because they appear to be running around in random circles like someone kicked their mound.
I don’t mind them as much as Fire Ants.
The ants you describe sound exactly like these ants............
