Permethrin SFR 36.8% is labeled for roaches, so it would kill roaches of any species or size that come into contact with it via direct spray or residual. If you are only seeing roaches occasionally and need a residual spray to create a barrier, then you have many options. Temprid FX is water-based and contains two active ingredients for longer control. It also does not have the odor that sprays with permethrin will have. If you are seeing different life stages and/or seeing roaches consistently, then we would recommend our Roach Control Kit Rotation A. Please see our Roach Treament Guide for more information and tips.
