Diagnosing bed bug bites can be hard for medical professionals. We often hear of doctors assuming a variety of skin conditions before bed bugs – especially doctors who haven’t encountered patients with bed bug bites before. While there is no specific test to determine whether bites are from bed bugs there are tests that can show whether or not it’s an insect bite. This is useful for ruling out issues like eczema or allergic reactions, but not for determining that any specific insect bite is a bed bug. To be sure you’ll want to check for other signs of bed bug infestation, such as the bugs themselves, moltings, and the characteristic staining of their blood meal feces.


Blood spots found on one’s sheets, bites and the presence of bed bug feces and cast skins are some of the indications of a bed bug infestation. Bites are commonly found on the parts of the body that are more likely to be exposed to bed bugs during sleep – 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 at times may occur in a line or a zigzag pattern. Bites normally look like small, flat or raised areas that may become inflamed, itchy, red or blistered. Bed bug bite reactions don’t always appear immediately after you’re bitten and may take a few days to begin causing symptoms. However, not everyone reacts to bed bug bites in the same manner.
