MIxing Tengard with Talstar will not make it last any longer and is not actually recommended. Mixing 2 insecticides together can contaminate an area making it highly repellent where insects will avoid it and neither can do their job of killing the insects. If you want a faster knockdown product, you can add something like Exciter. If you want a longer residual you should use something like Suspend Polyzone which can last up to 90 days on outside surfaces.
