I've had great results with Tango. First bought it over a year ago. No fire ants after about 3 months. I spread Amdro at the same time around the house and in the driveway, with Tango used where plants are growing. I only have 1/2 an acre but I try to spray all the lots around mine too. Had a few show up after a 4-5 month lapse in treatment. Now I do it every 3 months or so and they've been gone for 7 months at this point.
