Nothing kills fire ants. Treating one mound will only make them move and divide into a half dozen new mounds.
A small nuclear device will get rid of them. Preferably delivered from low orbit. It’s the only way to be sure.
I don’t know about that...really I don’t know. I have read where large tract treatment can be done successfully, but at what cost?
Yes, you treat one or more mounds, and the SOBs pop up ten feet away with a new mound. Seems like that is more apt to happen after a rain.
At best all I’ve done is suppress their activity to some extent. I have a pic of my foot where the damned things got on me last summer. Red blisters and pustules everywhere. Nice imported pest we have here. I was surprised to learn that fire ants in the south are a relatively recent problem...1954 or something?
Tried broadcasting ant poison once...worked great for about 5 months.
Soak the mound with lighter fluid, torch. For each mound that appears. I’ve had success with that method. Plus it’s fun to hear them pop when burning.
