Bed bugs are insects of the Cimex genus that feed on human blood, usually at night. Their bites can cause several health consequences, including skin rashes, psychological effects, and allergic symptoms. Bedbug bites can cause skin changes, ranging from mild redness to prominent blisters. Symptoms can last from a few minutes to days, although itching is usually present. Some people may feel tired or have a fever. Uncovered areas of the body are typically affected, and often three bites in a row occur. It is not known if their bites transmit infectious disease. Complications rarely include patches of dead skin or vasculitis.

Bedbug bites are mainly caused by two types of insects: Cimex lectularius (common bug) and Cimex hemipterus, which live primarily in the tropics. Their size varies from 1 to 7 mm. They are spread by crawling between nearby places or when carrying personal items. Infestation rarely occurs due to poor hygiene practices but is more common in high population density areas. Diagnostics includes both the search for bugs and the appearance of compatible symptoms. Bed bugs spend most of their time in dark, hidden places, such as seams in a mattress or cracks in a wall.

Treatment focuses on symptoms. Removing bed bugs from home is often difficult, in part because bed bugs can survive for up to a year without food. Re-treatment at home may be required. These procedures may include heating the room to 50 ° C (122 ° F) for more than 90 minutes, frequent vacuuming, washing clothes at high temperatures, and using various pesticides.

Bed bugs are found in all regions of the globe. The incidence of infection has been relatively common since its rise in the 1990s. The exact reasons for this increase are unclear; theories including increased travel of people, more frequent changes of used furniture, increased focus on pest control and increased pesticide resistance. Bed bugs have been a well-known human parasite for thousands of years.

Individual bite reactions range from no visible effect (about 20–70%) to small flat (macular) spots to protruding blisters (wheals and bullae) with severe itching, which can last for several days. Vesicles and nodules may also form. Bites often occur in a single line. Significant bleeding can also occur due to the release of blood-thinning substances in the bugs’ saliva.

Symptoms may appear as early as a few days after the bite. Reactions often become more active after repeated bites due to possible sensitization to the bugs’ saliva proteins. A skin reaction usually occurs in the bite area, most commonly the arms, shoulders and legs, as these are more widely exposed at night. Multiple bites can lead to a red rash or hives.
