Bed Bug 101: What do bed bug bites look like

Bed Bug

Bed bugs are parasitic insects from the genus Cimex, who are micropredators that feed on blood, usually at night. Their bites can result in a number of health impacts including skin rashes, psychological effects, and allergic symptoms. Bed bug bites may lead to skin changes ranging from small areas of redness to prominent blisters. Symptoms may take between minutes to days to appear and itchiness is generally present. Some individuals may feel tired or have a fever. Typically, uncovered areas of the body are affected. Their bites are not known to transmit any infectious disease.  Complications may rarely include areas of dead skin or vasculitis.

What do bed bug bites look like?

Bed bug bites can vary in appearance from person to person, and some individuals may not exhibit any visible reaction to the bites. However, common characteristics of bed bug bites include

Reddish welts or bumps

Bed bug bites often appear as small, red, and raised welts or bumps on the skin. They can be flat or slightly raised.

Clusters or lines

Bed bug bites tend to be grouped together in clusters or linear patterns. This is because bed bugs may feed multiple times during a single feeding session, moving around the skin.


Bed bug bites are often accompanied by itching, which can be mild to severe. The itching is usually the result of an allergic reaction to the bed bug's saliva.

Nocturnal occurrence

Bed bugs are nocturnal, and their bites typically occur during the night. If you wake up with unexplained bites, it could be a sign of a bed bug infestation.

It's important to note that the appearance of bed bug bites can be similar to other insect bites or skin conditions. Additionally, some people may not react to bed bug bites at all. If you suspect a bed bug infestation, it's advisable to inspect your sleeping area and consult with a pest control professional for confirmation and appropriate treatment. If you experience severe reactions or discomfort from the bites, seek medical attention.
