Great thread1 Thanks!

For a short-lived toxic chemical kill of Fire Ants, try this;
* in the morning (a time that the Queen is closest to the surface), pour enough rubbing alcohol on the fire ant tailings to penetrate at least 2 inches into the ground.
*Build a small dirt moat around the wet ant tailings.
*Slowly pour boiling hot water on the ant tailings, and fill the enclosed moat.
*Repeat 1-2 times a week, until ant tailings are not found for a few weeks.

The alcohol makes a quick kill, wets the ant tunnels, and becomes a killing fume head to the boiling hot water.

The alcohol is absorbed into the water.

The hot water heats up the ground and kills by overheating the ants.

Deep ant burrows or burrows under structures can be reached by pouring alcohol and hot water down a hollow metal pipe.

Leave metal pipe in place until the pipe has conducted its excess heat into the ground.

The alcohol fumes slowing rise to the surface and dissipate harmlessly into the air.

Warning: Probable root damage to tender plant roots.

close up of 'harvester ant' or 'red ant' as we called them. Main diet of the lizard and being destroyed by invading fire ants:

These little buggers have a painful sting if you mess with them.

My father used to destroy their hills on our ranch years ago- before we found out about the horned lizard's dependence on them. Now when we find one (rare), it is left alone in hope that someday the lizard will return to our place.
