Bed bugs have flat bodies and may sometimes be mistaken for ticks or small cockroaches. Bed bugs feed by sucking blood from humans or animals. Adult bed bugs are reddish brown in color, appearing more reddish after feeding on a blood meal. Nymphs are clear in color and appear bright red after feeding. Bed bugs can live in any area of the home and can reside in tiny cracks in furniture as well as on textiles and upholstered furniture. They tend to be most common in areas where people sleep and generally concentrate in beds, including mattresses, boxsprings, and bed frames. Bed bugs are most active at night and bite any exposed areas of skin while an individual is sleeping. The face, neck, hands, and arms are common sites for bedbug bites.
