easiest way to get rid of fire ants?

Fire ants are one job where the two-step method actually earns its name. Step one: spread a fire ant bait over the whole yard, not just the mounds, when the ground is dry, no rain is due for a day, and they're out foraging (warm afternoon). Don't poke the mound first. Step two, a few days later: treat any mound that's still active with a mound drench or more bait right around it. Boiling water and kicking the mound mostly just makes them move a few feet over. And check the bait is fresh, an opened bag that's sat in the shed a year goes rancid and they ignore it.
