We have a great video that shows where to spray for perimeter and interior spraying. Please click on the link here to see the video. Please be aware that Martins Viper Insecticide Concentrate will only kill the roaches that contact a treated surface and alone will not be enough to eliminate an infestation of roaches. We would recommend one of our roach control kits. You can see the kits by clicking on the link here. We also have a great article for eliminating them here.
