I have a customer that was complaining about ants in her lawn and beds. I did a backpack spray of Tempo SC whever I spotted ants and or ant hills plus a perimeter spray of the house, 5ft out and 1ft up the side. Along with that I did a granular of Sevin. It's one week later. I have had little to no control. I know the Sevin hasn't taken effect due to the lying weathermen, but should I have seen atleast some control? Any thoughts?
