Arilon Insecticide is labeled for roaches, and should do a great job toward helping you eliminate the infestation. We would also recommend that in addition to an insecticide like Arilon that you also use a high quality roach bait gel such as Invict 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. Arilon 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 or so depending on such factors as how healthy the roach is, and how long it spent on a treated surface. 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. We would recommend that you look over our article on How To Get Rid of Roaches as well if you have a moment.
