Disinfection of the rooms doesn’t help with the bugs.
Even the most luxury hotels have this problem: bugs may appear after the previous guests and end up in someone’s luggage. This uncomfortable fact is never told to anyone in order to save their reputation. And if these unpleasant insects have already occupied the hotel premises, it’s really hard to get rid of them. Bugs settle in soft furniture, blankets, and pillows very fast. And even though most hotels have disinfection procedures, they don’t do them very often because leaving all rooms vacant means losing a ton of money.
