Does EcoVia EC offer a residual effect when applied outside?

I want to use this product as a spider barrier around the outside of my home. It will obviously be subjected to rain, sun, etc. How long will it provide an effective barrier?

Answer:

Per the manufacturer, EcoVia EC has a 4 week residual. EC products do not have the same length residuals as synthetic insecticides.
