Both products have an active ingredient that is classified as a synthetic pyrethroid, so they really are very similar in the way that they work. Suspend SC contains the active ingredient deltamethrin and is a bit more versatile when it comes to bedbug treatments though as it can be sprayed on mattresses, carpets (spot treat only) and on furniture (crack and crevice only). Demand CS cannot. Demand CS contains the active ingredient lambda-cyhalothrin, and it is micro encapsulated which will make it last a little bit longer in outdoor applications.
