Our first service (initial fire ant treatment) was good and seems to have started to remove the ants. There are still a lot of ant piles popping up, and bugs around. I guess it will just take time. The other thing was that for a yard our size (1 acre), the technician seemed to finish the whole service in around 20minutes. I am not sure if that means he was efficient or if he didn't spend enough time on our lawn.
