Roaches infest some of your rooms at your hotel when you're inactive, and force your hotel to close until you clean them out yourself. Your wimpy Employees will not clean the roaches from the room(s) for you because they are too scared to enter, so it is up to you to clean it up.

Most often when inactive for around 3 days, your hotel will get infested with roaches and close, thereby denying you extra potential income and wasting shift time.

To clean out those roaches will cost you 300 coins.
