While Martin's Permethrin 13.3% is labeled to control roaches, it is not the best to use since it only kills those that contact a treated area. You can use it outside around the perimeter to help with killing any trying to get in, but we do not generally recommend it for effective roach control indoors. Keep in mind that roaches are a difficult pest to treat and usually the use of more than one type of product is necessary to completely eradicate them. Please take a look at our Roach Control Guide for more information. We would recommend one of our roach control kits for best control if you have a roach infestation inside.
