Do bedbugs cause harm or spread pathogens (disease-causing germs)?
Despite what you may have heard or read elsewhere, bedbugs are not known to transmit any infectious agents. Treatment of bedbug bites usually involves self care, but in more severe cases you may need to see your doctor. The affected person should resist the urge to scratch the bites, as this may intensify the irritation and itching, and may lead to secondary infection. Where do bedbugs occur? Bedbugs occur nearly worldwide. They became relatively scarce during the latter part of the 20th century, but in recent years their populations have resurged, particularly throughout parts of North America, Europe, and Australia. They are most abundant in rooms where people sleep, and generally hide nearest the bed or other furniture used for sleeping. Bedbugs are most active in the middle of the night, but when hungry, will venture out during the day to seek a host. Their flattened bodies allow them to conceal themselves in cracks and crevices around the room and within furniture. Favored hiding
