Bed bugs can hide undetected for months. Signs of an infestation include reddish-brown blood spots on sheets or mattresses, a strong musty odor, or sightings of the pests themselves, which are the size, shape and color of an apple seed. Home or business owners who suspect a bed bug problem should contact a pest control company as soon as possible to schedule an inspection.
