Bed bugs feed only on blood. If bed bugs are living in extremely cool conditions, they can survive up to a year without a meal, but they generally are found in warm areas such as beds, thus the name. Bed bugs are more active at night when the host is asleep.
Bed bugs are found in crevices and cracks, especially mattress seams. They are also found in furniture, sheets, suitcases, behind baseboards, picture frames and electrical outlet plates. Often found in hotels, it is a good idea to inspect the mattress seams before you stay in any new room. In hotels, bugs are transmitted through luggage, purses and briefcases, which can make managing infestation a problem in need of a trained professional.
