The room flloor is laminated wood, not carpet. I washed all the bedding twice before my brother come home the last time.. but it still happened

Now that I know bed bugs do not only live on the bed/mattress, I plan to clean everywhere else, too - like the bed frames, windows, closets... Hopefully it'll help.

Do you have any ideas why it'd bite some people but not the others? I can only hope it won't bite my uncle & aunt - otherwise we'd be soooooo embarrassed! I am tempted to ask them to stay at the hotel, but my parents really want them to stay at our house. Plus, they told me that a new bed in my house is supposed to be much cleaner than a bed in a hotel..
