There are several theories regarding the resurgence of bed bugs. One theory attributes to the reemergence to the lack of DDT use for pest control. Another theory points to the increase in international travel. A main reason is simply a lack of knowledge of their existence and behavior. They often go undetected until they become a major infestation and have already been transported to new locations.
Anyone can knowingly pick up bed bugs from a location they presently exist – an apartment, other residence hall rooms, movie theaters, hotels, motels, etc. They can also be harboring in secondhand furniture. Bed bugs are equal opportunity pests – they will infest anyone, anywhere, and are not a result of poor hygiene or uncleanliness.
First, look at the room you are staying in to seek potential hiding places for bed bugs, such as carpet edges, mattress seems, pillow linings, head boards, wall trim or other tiny crack like places bed bugs might hide.
