If you have a window on your doorway you might prefer to caulk the frame around the window, just in case there’s sufficient room for the cockroach to get across. Your house should be sealed from outside in: be sure that your windows have screens that are free from rips or holes. The screens must have no gap between the inside window and screen frame. In the summertime, if you have your window open for the air, roaches will be capable to get inside through any small gap.
