Katie from Caldwell, Idaho writes

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?


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