Does Steri-Fab kill on contact? As opposed to the other products, does Steri-Fab provide a long-term protection?
Demand CS and Suspend SC are both synthetic pyrethroid concentrated insecticides that need to be diluted with water prior to use. Both products offer a residual that will keep killing insects even after the product has dried. Steri-Fab on the other hand offers a fast knockdown, but does not offer any residual. Steri-Fab is also useful when you need to treat sensitive areas where you cannot use other products.
