Bed bug bites can look different from person to person, and not everyone reacts to them in the same way. However, most people develop marks similar to mosquito or flea bites, which are slightly swollen bumps with a reddish bruise in the middle that itch. Bed bug bites can appear anywhere on the body where there is skin, but they tend to occur on areas exposed during sleeping, such as the neck, face, hands, shoulders, arms, and legs.

Some key characteristics of bed bug bites include:

• Small, flat or raised areas that may become inflamed, itchy, red or blistered.
• Bites may not become obvious for several days or at all on some individuals.
• 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, and 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.

Its important to note that a visual examination of the bites on your skin gives your healthcare provider proof of a bite, but the bites may look similar to other bug bites. You can confirm the diagnosis by locating and identifying a bed bug in your sleeping environment.
