This is the third year we've purchased Extinguish Fire Ant Bait. Each time we had less than favorable results, but there are few items on the market for spreadable fire ant control. I'd usually have to reapply Surrender after a short time, but again, the reviews are good for Extinguish so I gave it another try this year. We live in SC, and our farm is sand not clay. Fire ants love our property. My husband spread the Extinguish last week. Walking the pastures all the fire ant beds were thriving. Today I walked part of the pastures using Surrender knowing it would kill the fire ants. Lost another $200 plus dollars. Won't be using Extinguish again.
