Since the late 1990’s, the bed bug population have made a resurgence in the United States and other large nations of the world. The rapid spread of these insects is due to their ability to travel with people while avoiding detection in many cases.
A main factor in the spread of bed bugs is a lack of awareness by the public, although this has increased with high profile infestations in places like New York. Because these bugs can hide on a person or in their luggage so well, they go unnoticed a majority of the time.
Many of the first cases that were discovered were in hotel rooms and thought to be a result of travelers unknowingly bringing these pests into the rooms.
