Get Rid of Fire Ant Mounds ??

A reader’s tip in a southern magazine suggests the following as a way to get rid of fire ant mounds.

Take a shovel full of mound A and distribute it on mound B.
Take a shovel full of mound B and distribute it on mound A.
Bigger mounds require more shovelfulls.

The writer say that both mounds and their inhabitants will disappear.

Has anyone on the SDMB’s tried this and did/does it work as suggested.

Or you could fight fire with fire and use a flamethrower on them.
