If you have bed bugs, you may also notice itchy welts on you or your family member’s skin. You may also see the bed bugs themselves, small bloodstains from crushed bed bugs, or dark spots from bed bug droppings in your home. Bed bugs often hide in or near beds and bedroom furniture, and in the tufts, seams, and folds of mattresses and daybed covers. In more severe infestations, bed bugs may spread to cracks and crevices in bed frames and box springs; behind headboards; inside nightstands; behind baseboards, window and door casings, pictures, and moldings; and in nearby furniture, loosened wallpaper, and cracks in plaster and flooring. Bed bugs may also hide in piles of books, papers, boxes, and other clutter near sleeping areas.
