Household or otherwise bed bugs feed on human blood, leaving bites, redness on the skin and causing a lot of discomfort. Itching from a bite deprives a person of full sleep, makes him aggressive, nervous, and reduces concentration. But, besides this, bed bugs can cause really serious health problems.
In the body of bed bugs, pathogens of various infectious and invasive diseases caused by them (plague, typhus and relapsing fever, tularemia, coxiellosis - Q fever) can persist. It has been established that bed bugs can be carriers of the hepatitis B virus when feeding.
