Spectre 2 SC is labeled for roaches and should do a good job. This can be used indoors and outdoors. Indoors, you will spray around the cracks, crevices and baseboards in the problem areas. Once the product is dry, it is safe for any children and/or pets to return to the area. Outdoors, you will spray around the perimeter of your home. The good thing about this product is that it is a non-repellent. This means that the roaches will not detect it when they come in contact with it. They will just get it on themselves and die as well as carrying it back to the colony and spreading it throughout.
Another good item to use is Gentrol IGR (insect growth regulator). This will stop the roaches from reproducing. It can be mixed in the same tank as Spectre.
