Our beds have legs. Peasants sleep on floors and those low things. Our bedding is cleaned regularly. Peasants don’t clean their bedding (or their clothes, or themselves).
If you clean like your American mom did, you won’t have bedbugs.
There is a reason for these cultural habits.
A lot of five star hotels have had bed bug infestations, and they're some of the cleanest abodes known to man.
Bed bugs aren't attracted to dirt. They're attracted to warm blooded mammals, regardless of the environment. When they infest a home, they don't just inhabit mattresses, bedding, and upholstered furniture, they get into the walls, floors, ceilings, cabinetry, and even electrical boxes.
If a few of them sneak into your spotlessly clean home attached to a neighbor child's blanket, backpack, or clothing, they'll set up shop just like any other place.
