Having an immaculately clean and tidy home is not going to prevent you from hosting a Bed Bug congregation in your room. It only takes exposure to one single Bed Bug for you to have a whole problem of your own. The issue I am finding in Australia is that because people are not interested in publically advertising that they have active Bed Bugs camping out onsite in their immaculately clean and tidy home, their guests are completely unaware that they could be taking home an unwanted guest of their own on their clothing, shoe, bags etc when they leave from their visit. If you only happen to take home 1 Bed Bug egg there is a reasonable chance for you that  this eggs id going to hatch and make a meal of you.
