Yes,Suspend SC is labeled for roaches, and should do a great job helping you eliminate the infestation. We recommend that in addition to a concentrated liquid insecticide like Suspend SC you also use a high quality roach bait gel to help get the roaches that hide in places where you cannot spray (cabinets, counter tops, drawers) as well as an insect growth regulator such as Gentrol Point Source to help stop the breeding cycle of the roaches if found indoors. Suspend SC is a residual which means it will not be a contact kill for the roaches. It could kill a roach within a few hours or within a day depending on how healthy the roach is, and how long it spent on a surface that was treated with Suspend. The spray will typically last indoors 90 days and outdoors 30 days, but for an active infestation you would want to retreat every 30 days indoors until the colony is eliminated.
