Cy-Kick CS is labeled for a contact kill only for fleas. According to the product label, Cy-Kick CS will not leave an effective residual for continued control of flea populations. We recommend using the products contained in our Outdoor Flea Kit for best results. This kit contains Onslaught which kill the biting adult fleas and Martins IGR which will help stop juvenile fleas from reaching a breeding cycle.
