Signs and Symptoms
The morning after being bitten the bedbug, you may notice an itchy hive-like bump at the site of the bite mark, which will go away through the course of the day. There may or not may not be a visible bite mark in the center of the bump. After that, what start as small bruise-like areas turn into red, intensely itchy bumps on the exposed parts of the body (arms, legs, chest, and sometimes the face). There may be a clustered configuration of 3 bites in a line (commonly known as "breakfast, lunch, and dinner"). Resolution takes about 2 weeks and leaves some darkening of the skin (post-inflammatory hyperpigmentation).
You may see tell-tale signs of the bedbug's presence, such as blood stains on the sheets, flecks of bedbug dung on or around your bed, or you may smell a sweet odor that occurs when there is a large bedbug infestation. You may be able to spot a moving bedbug if you are searching at night.
