Demand CS with solves the most difficult insect pest control problems. Among those are mosquitoes, which are more than just a nuisance. They also transmit the deadly West Nile Virus. Demand CS will help control this problem. Demand CS is the most active pyrethroid pest control you can use. Its exclusive iCAP technology packs up to 10,000 powerful capsules of insecticide into every square inch of surface you treat. Demand CS doesn't just work better. It works longer. Studies show that Demand CS is up to 200 times more active than other insecticides on flies, spiders, mosquitoes, bedbugs and other insects. The reason is because the iCAP technology shields the active ingredient lambda-cyhalothrin from UV rays, ph extremes and absorption into porous surfaces. This allows it to remain intact longer and ready to be released when an insect makes contact.
