PF Harris 4 oz. Bed Bug Black Powder. This long-lasting powder effectively kills even the toughest pyrethroid-resistant bed bugs. The 4 oz. puffer bottle comes complete with an applicator brush for easy application. Apply dust evenly as a light coating, creating a barrier through which bed bugs must crawl. Electrical switch plate covers can be removed to allow access to voids, but dust should not be applied directly in the electrical boxes. Treat the mattress and box spring, paying particular attention to tufts, folds, and edges.
