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.
