Bed bug bites are caused by bed bugs primarily of two species: Cimex lectularius (the common bed bug) and Cimex hemipterus. Infestation is rarely due to a lack of hygiene. These insects feed exclusively on blood and may survive a year without eating. They are attracted by body warmth and carbon dioxide.
Around a bite, the body's reaction can cause anything from slight discoloration of the skin, to large red welts similar to mosquito bites or bruises. Bed bug saliva contains an anticoagulant (something that prevents blood from clotting) which may cause the bites to bleed. Several bites in the same area may lead to general redness of the skin and to hives-like symptoms not necessarily around the bites themselves.
Even though bed bug bites cause itchiness and irritation to the skin similar to flea, spider and mosquito bites, there are a few differences. The bites of bed bugs usually appear as small, red welts and tend to show up in groups or in a line formation on the hands, feet, neck and other exposed body parts during sleep.
The bite marks are similar to that of a mosquito or a flea — a slightly swollen and red area that may itch and be irritating. The bite marks may be random or appear in a straight line. Other symptoms of bed bug bites include insomnia, anxiety, and skin problems that arise from profuse scratching of the bites.
In most cases, a mosquito bite produces a red, itchy bump, which can bleed if scratched. Those with mild reactions to a mosquito bite can take antihistamines to reduce itching and swelling. Consult a physician before taking any new medications.
Bed bug bites vs. mosquito bites Bedbug bites and mosquito bites can both be red, swollen, and itchy. If you have a line of bites that appear in a small area of your body, they're more likely to
