Bedbugs currently are not considered vectors of disease. They have been extensively studied in laboratory environments yet have not been capable of passing disease from one host to another. This is good news from a health perspective; however, there are other issues that come with bedbug infestations that are important to recognize.
First and foremost, the presence of bedbugs does not indicate a filthy or unsanitary environment—remember, they can hitch a ride on anything and therefore appear in places one may not expect. The most common problems associated with bedbug infestations are feelings of anxiety/stress, possible secondary infections from itching, sleeplessness, and the social stigmas that some feel are attached to their presence.
Once bedbug populations are identified, chemical controls can often be more harmful to people than the bedbugs themselves if they are not properly applied. Therefore, seeking out professional assistance and following product labels is incredibly important.
