Bed bugs are tiny parasitic insects that have made a comeback after about 50 years of limited activity in the U.S. They are transported by people traveling internationally and bringing them back.
Adult bed bugs have a distinct reddish-brown color and have flat oval-shaped bodies about 1/4 inch in length. They may lay up to five eggs in one day and their eggs are nearly invisible by an untrained. When bed bugs hatch they are only the size of a pinhead. Like ticks and fleas, bed bugs also feed on blood.
Signs you have a bed bug infestation are small spots of blood on mattresses and linens, tiny brown droppings, exoskeletons shed by growing nymphs, tiny white eggs, several bites in a row on your arms, legs, or elsewhere.
