I would like to know if anyone has first hand experience with these products. I have read the labels over and over again but can't determine which would work better for me. I would like to use it for perimeter treatments and for surface feeding insects. As far as surface feeders the sodwebworm is my main target. I know it's early for them, but I want to be ready. Talstar is more expensive but goes farther per gallon than the Astro(permethrin). I don't care about cost, I just want a good product with a good residual. I checked with my local extension office, and would have been better off asking my 8 year old daughter.
