Bed bugs are parasitic insects that feed upon the blood of their hosts. Preferring the confined habitats inside beds and other furniture, remain mostly unseen during the day and come out at night to feed on people while they sleep. Despite being associated with rough urban environments, bed bugs can be unknowingly picked up from many public places such as theaters and hotels to be brought back to homes where they nest in furniture and go on to multiply to a point where they are difficult to deal with. Bed bug bites cause severe health effects such as rashes, allergic reactions, and physiological ailments.
