I've reached an uneasy truce with our fire ants, I don't bother them as long as they don't build their mounds in areas where we walk or sit. For those I'll pour boiling water all over & around their mounds, sometimes first taking a shovel & poking a deep hole in the middle of the mound. When I clean out the coops I sprinkle some sort of insecticidal dust around the places where they set & lay, in & around the nest boxes. And before I place a broody hen in her pen I'll sprinkle the dust all around there.
If I've left the faucet open on the hose capped with the sprayer nozzle it will be filled with scalding hot water. I will look around for a nearby fire ant mound to spray with that hot water while I wait for new cooler water to come through. If I can't find a mound handy, I'll try to boil some weeds instead.
