Both of the products you mentioned are great for a variety of pests and would work well for your needs. While the Demon and Demand CS will last about the same amount of time outdoors, the Demand CS will dry clear on surfaces where its sprayed whereas the Demon WP will leave behind a slight powdery residue that can be noticeable on darker surfaces. This is normally the biggest determining factor for homeowners, especially if you plan to spray it indoors at all, or if you have a darker siding or brick around the outside.
