Demon WP is a great choice for spider control. Demon WP is a wettable powder that is diluted in water, and then sprayed around door frames, window frames, in areas where utilities (cables, pipes, wires) enter into a structure, around the bottom of the foundation and other area where insects are known to harbor. Demon WP can leave a white powdery residue on dark surfaces. If the powdery residue is a concern, you can choose a micro-encapsulated product such as Onslaught Fast Cap Spider and Scorpion.
