Anytime you see RTS on a product, it means it is Ready To Spray, and you just hook your water hose right up to the bottle and it will dilute it automatically for you. If you see RTU, this means it is Ready To Use, so you dont have to dilute it with anything, and sometimes these will come in a bottle that allows you to spray directly from it, similar to a windex style bottle. Please let us know if you have any other questions.
