fire ants! Argh! Best treatment method?

I've got fire ants.  Who doesn't, right?
I've noticed more mounds after our most recent rains.  So....what's
the best way to get rid of these, and to help prevent future mounds
from appearing?  I know I won't get rid of all of them, all the time,
but I'd like to keep them at bay as much as possible.

Any (sensible) suggestions?

Thanks!
