Bed bugs can mature in about 30 or so days. They live about seven to 12 months. This makes bed bug removal difficult to do without the help of a professional. Bed bugs primarily feed on humans sleeping in bed at night. The bite is painless, and the blood meal takes about 12 minutes. Bed bugs are skilled hitchhikers. They are typically transported by humans and human belongings. Bed bugs hide during the day in mattress seams, cracks and crevices on headboards, in tubing and other voids in bed frames. As populations build you can find them behind baseboards, picture moldings, around door and window casings and in seams in dressers or night stands in folds in curtains and behind electrical switch plates. Bed bugs are good at hiding, but not good at hiding evidence.
