If it kills the ants....it's effective; Only difference is the cost. When I moved to where I now live, I had fire ants all over the place. When I asked my next door neighbor what to do about them, he came over with a bag of...............GRITS!
Plain ol' white grits. I thought he was funnin' me and said as much. He just proceeded to take the old broomstick he brought with him, punched a hole in the center of the mound and poured a cupful into and around the top of the mound. Three days later, the mound was dry and no more ants. Did that on every mound I found.
Asked him later how it worked, and he said the ants take the grits down into the tunnel and it swells up when eaten and kills the colony.
Has worked for me for 29 yrs. Cheapest cure I've ever found.
Say what you will, but don't knock it 'til you've tried it.
WILL.
