We would not recommend mixing any other products like EcoVia or similar items with the DSV. DSV is designed to sanitize and eliminate any and all materials on the surfaces and will either be rendered less effective if mixed with EcoVia, or it would do the same effect to the EcoVia as it would anything else on the surface you spray it on and break it down and waste the product. You should spray DSV first, then follow up with use of EcoVia in the approved labeled areas for residual insect control.
