Since most bed bugs are large enough to see with the naked eye, you would think that they would be immediately noticed in an infested room. Unfortunately, most people do not know where to look or what to look for. Early infestations when just a few bed bugs are present are extremely difficult to find, and yet this step is crucial to prevent bed bugs in the home. They typically will be well hidden behind the headboard or inside the box spring. Tell-tale signs, like cast skins and black fecal droppings, will only be noticeably present on a mattress or bed skirt after an infestation has grown in numbers over a period of weeks and months. While inspecting your hotel room (or anywhere you sleep outside the house) is essential to early detection, many people have reported bringing bed bugs home even after a thorough search.
How do you get bed bugs? There are three ways that bed bugs can find their way into your home:(1) Travel: Unknowingly bringing bed bugs home from hotel, hospital, college, friend's house. (2) Furniture: Purchasing used (or sometime new) furniture that contains bed bugs, especially mattresses. (3) Multi-tenant buildings. Once bed bugs are introduced in one unit, they will eventually find their way to any and all adjacent units/bedrooms. Dirty rooms are no more likely to contain bed bugs than spotless five-star hotels. Bed bugs can be found anywhere that people sleep. It's not very useful to argue over whose fault it is that bed bugs have entered a building. It's actually nearly impossible to prove, never intentional, and even for the most diligent people, never totally preventable.
