how can you tell the difference between flea bites and bed bug bites?
Flea bites are often on the lower body, while bed bug bites are usually on the upper body. Flea bites can be grouped, while bed bug bites are often lined up in a row. Both produce inflammations, but, in some people, bed bug bites can produce larger inflamed welts that are very noticeable. Both are very itchy.
