​Bed bugs are insects that have 3 main body parts, six legs, and 2 antennae. They are typically light brown or reddish-brown in color and grow up to about 7 mm long. Many people compare the size and shape of a bedbug to an apple seed. Since bed bugs feed exclusively on blood, their shape changes based on how recently they have eaten. Unfed bed bugs are flat and oval-shaped, while a full bed bug looks swollen and more balloon-shaped. Bed bugs do not have wings and will not jump or fly. They may also appear to have stripes because of the microscopic hairs that grow along their segmented abdomens. Bed bugs are most often found within a few feet of a sleeping area.
