I have boric acid down all around base boards, cracks and crevices. And IGR before I spray?
You do want to apply Cyzmic CS Micro-encapsulated Insecticide to a clean surface and remove any dust or debri before application so that the spray contacts the surface for better application and continous barrier. Dusts are best used applied to cracks and crevices and under baseboards where it will not be disturbed.
