Generally, bedbug bites are harmless, but if they are deep enough, you might be in danger of developing an allergic reaction or anaphylaxis. If you find a bite, it is important to clean the area daily to prevent infection and promote healing. You should also avoid scratching the bite area, as it will introduce bacteria into your skin, which will lead to secondary infections.
Bedbugs live in the cracks and crevices of your bed and can enter your bloodstream. They are not confined to the bedroom, and can easily hitchhike from your home to another location. They can also infest couches, chairs, picture frames, and headboards. They can even be found in public transport systems. Inadvertent transport of these bugs is one of the main causes of new infestations.
Researchers believe that bedbugs can carry pathogens in their saliva, hemolymph, and ejaculate. These compounds may help these bugs transmit the pathogens to their hosts. Scientists hope that finding these compounds will lead to a better understanding of the pathogens.
Despite the fact that bedbugs are largely resistant to most pesticides and other methods of removal, they are considered a nuisance rather than a serious health concern. There is no evidence to link the presence of bedbugs to human disease, but the biggest threat they pose is secondary bacterial infection, which can occur when they scratch the human host.
