We would recommend using Bifen IT for treating indoors and outdoors. Bifen IT is a great general all purpose insecticide that can be used as a perimter treatment on the outside of home (windows, doors, foundation, yard, trees, bushes) and inside as a crack and crevice spray. You will get a 30 day residual on the outside of the home and 90 residual on the inside of home.
