Demon WP Insecticide

Walt Cline - Pest Control Professional Pro Tip: "Demon WP packs are easy to use, just mix them into water. Mix well in your sprayer, and use the finished solution within a couple of days. Demon was a good German Roach killer, but they seem resistant to it now. Gel and powder baits are the best choices for the German Roach.

Cyper WSP ( packets) have the same label as Demon WP but are more economical. Both Demon WP and Cyper WSP are classified as a long-term residual insecticides.
