What is your preferred method?
Poison. Only works on one hill at a time but if you’re persistent they will go bother someone else.
I like a high mixture / concentration of permethrin. Little bastards die quick.
Gloss black Krylon spray paint takes ‘em out. Hit ‘em with it when they are out. They go back down in their nest and see that they are black and they stop working and kill each other.
For the record I do NOT agree with my horrible joke. It’s mean, foul and ugly. The FBI, DHS, and BLM hate it. And it sure as hell wouldn’t make it past the Texas school book commission, and may it be banned in Boston and placed in the Vatican index of forbidden jokes.
And SHAME on anyone that laughed. That only encourages me.
Nuke ‘Em From Orbit!
I tried black powder…just once.
Blew the little bastards everywhere.
Terro fire ant bait.
I pour gasoline on the mound. Kills them instantly. Dissolves their bodies…never to be seen again. You can come back 10 minutes later and dig way down into the mound and find no ants.
A bucket connected with a hose to mower exhaust, cover the mound and start the mower. Pump the mound full of carbon monoxide.
Use flexible electric metal conduit and fittings. The threads are the same as the muffler hole threads on the mower.
Boric acid powder or borax laundry soap.
At my dad’s farm he would encounter fire ant mounds that were 3 to 4 feet high. If you weren’t careful it would tip over a tractor when you drove over it. We would pour diesel into the mound, let it sit for a while then come back with gasoline and light it on fire. The diesel would suffocate them and the gas would burn them up.
Gasoline....I’d pour 6-8 ounces on the mound and give it a minute or two to soak to the bottom of the nest.
Ignite.....goodbye ants.
I douse the mound with lighter fluid then touch it off. They don’t come back.
Fipronil
