Bed bug bites typically appear as slightly swollen bumps with a reddish bruise in the middle that itch, similar to mosquito or flea bites. They can be small, flat, or raised areas that may become inflamed, itchy, red, or blistered. The bites are commonly found on areas of the body that are exposed during sleep, such as the hands, neck, face, shoulders, legs, and arms. While not always the case, bed bug bites are often grouped together in a small area and may occur in a line or a zigzag pattern. The appearance of the bites can vary depending on individual characteristics and skin tone. Bed bug bites can develop into red, itchy, and swollen welts, and they can occur anywhere on the body that is exposed while sleeping
