Bed bugs are small, oval shaped, wingless insects. The bugs are about the size of apple seeds. The eggs are white, and are found in clusters. The eggs are about the size of a pin head. The flattened bodies of bed bugs allow them to hide in very small places such as seams of mattresses, cracks, crevices, electrical outlets, box springs, bed frames, headboards, behind wallpaper, or in any other objects around a bed or on the floor. Bed bugs cannot climb metal or polished surfaces and are not able to fly or jump.
