Bed bugs can result in a number of health effects including skin rashes, psychological effects and allergic symptoms. Bed bug bites may lead to skin changes ranging from non visible to prominent blisters. Symptoms may take between minutes to days to appear. Itchiness is common, while some may feel tired or have a fever. Typically uncovered areas of the body are affected. Classically three bites occur in a row. Bed bugs bites are not known to transmit any infectious disease.
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
