In recent years, bed bugs have also made a comeback in the U.S. They are increasingly being encountered in homes, apartments, hotels, motels, dormitories, shelters and modes of transport.

How Infestations Originate
It often seems that bed bugs arise from nowhere. The bugs are efficient hitchhikers and are usually transported in on luggage, clothing, beds, furniture, etc. Outbreaks can often be traced to travel, especially in countries or cities where bed bugs are common. This is a particular problem for hotels, motels, and apartments, where turnover of occupants is constant. Bed bugs are small, cryptic and agile, escaping detection after crawling into suitcases, boxes, and belongings. The eggs are almost impossible to see when laid on most surfaces. Use of secondhand beds, couches, and furniture is another way that the bugs are transported into previously non-infested dwellings.
Once bed bugs are introduced, they often spread room to room throughout a building. Unlike cockroaches that feed on filth, the level of cleanliness has little to do with most bed bug infestations.
