No two people react to bites in the same way, although some reactions are similar. Because of the saliva that they leave behind, the first reaction is usually severe itching and irritation. This is often followed by a raised appearance on the contacted area. Some people, however, react by having welts and hives all over the body. Still others will have small, pinkish bumps that are concentrated in one area.
Check the mattress throughly, paying close attention to seams and tufts along the edges. Flip the mattress over and inspect the bottom carefully as well. Pay particular attention to any rips in the fabric. View the fabric on the bottom of the box spring and shine a flash light to verify that bed bugs have not penetrated the interior of the box spring.
Unlike those of other insects, bed bug bites may sometimes appear in tight lines of multiple, small, red marks where multiple bed bugs have fed along an exposed area. Bed bug bites can cause itchiness. Initially, a victim may detect a slight burning sensation. The burning area then develops red bumps, known as papules or wheals (rash). In extreme cases, bites may swell dramatically or turn into blister-like skin inflammations.
