A number of other symptoms may occur from either the bite of the bed bugs or from their exposure. Anaphylaxis from the injection of serum and other nonspecific proteins has been rarely documented.[5][10] Due to each bite taking a tiny amount of blood, chronic or severe infestation may lead to anemia.[5] Bacterial skin infection may occur due to skin break down from scratching.[5][11] Systemic poisoning may occur if the bites are numerous.[12] Exposure to bed bugs may trigger an asthma attack via the effects of airborne allergens although evidence of this association is limited.[5] There is no evidence that bed bugs transmit infectious diseases[5][7] even though they appear physically capable of carrying pathogens and this possibility has been investigated.[5][3] The bite itself may be painful thus resulting in poor sleep and worse work performance.[5]
Since bed bugs can be found throughout the world, many people have suffered from their bites. Since you are reading this, you have also most likely been a victim but don’t worry, you are not alone. Their primary diet is blood, which makes humans their meal of choice, definitely not good news for us! Based on personal experience, they can leave a rather nasty, red mark which can itch like mad. No wonder people say “Goodnight and don’t let the bed bugs bite!” What do these bites look like (and what to do if you are bitten) and what are some ways that you can get rid of them?
Scratching can cause superinfection, leading to impetigo, cellulitis, or folliculitis.27–32 Reactions typically resolve within one to two weeks without treatment.32 Systemic reactions have been described, including asthma, generalized urticaria, angioedema, iron deficiency anemia, and, very rarely, anaphylaxis.33–36 Although bedbugs have been suspected to be vectors of more than 40 microorganisms, there is no evidence that they are involved in the transmission of disease.5
One bed bug will usually take more than one bite. Once a bed bug inserts its mouthparts and finds a suitable blood vessel, it will begin feeding. However, finding the right blood vessel may take more than one injection into the skin. In addition, bed bugs are very sensitive to movement by the host they are feeding on. Therefore, if a sleeping person moves, a feeding bed bug will probably withdraw its mouthparts and begin its search for a blood meal on another part of the body. It’s important to remember that the number of bites a person receives is not indicative of the number of bed bugs that feed on that person.
