In October, the French collectively freaked out over bed bugs.    Social media erupted with supposed pictures of the     parasites in cinemas, trains, and subways. Pest control    agencies, exterminators, and owners of bed bug-sniffing dogs    were inundated    with panicked calls. Politicians breathlessly demanded rapid    government action. Of Paris, uncritical media reports declared that    the entire city is infested with bed bugs.  
    Google Trends     data shows the mass paranoia in chart form.  
    The thing is, it doesnt appear that the countrys bed bug    problem warranted such a swift and sudden panic, which seemed    to have started with a few social media posts that went viral.    The insects population     didnt erupt overnight. Instead, the French were likely    gripped by a social panic.  
    Dr. Robert Bartholomew    is a sociologist specializing in mass    hysteria and social panic. He teaches at the University of    Auckland.  
    What has been reported in Paris looks like something from a    Grade B monster movie, he told Big Think. Going by press    accounts, you would think they were everywhere  and that is    not the case.  
    Most French are not bed bug experts, and are likely mistaking    ticks, carpet beetles, or some other creepy crawly for bed    bugs, Bartholomew added.  
    Michael    F. Potter, an emeritus professor of entomology at the    University of Kentucky, knows exactly what bed bugs look like.  
    Adult bed bugs are reddish-brown, with oval, flattened bodies.    Their coloration is similar to an apple seed although their    size is closer to a lentil, he described.  
    Like vampires, bed bugs feast on blood and avoid the light,    spending their days hiding in mattresses, box springs, bed    frames, and headboards. At night, they crawl to their    unsuspecting, sleeping victims and gorge themselves on blood    for three to ten minutes, then scurry back to their cozy    crevices. Bed bugs dont transmit diseases to humans, and their    bites are painless. The nips can leave red, itchy welts,    however.  
    Relative to human pests like mosquitoes, ticks, and fleas, bed    bugs are rather innocuous. But the fact that they covertly    invade your bed  a place of privacy, comfort, and safety  to    suck your blood as you sleep makes them uniquely unsettling.  
    Their stealthy, squirm-worthy reputation undoubtedly fueled    Frances collective anxiety.  
    There is a real psychosis, Jean-Michel Brenger, an    entomologist at Mediterranean University Hospital Infection    Institute in Marseille,     told the New York Times. This is the first time    people have called to ask me to come to their home to check for    bedbugs when they havent been bitten, they havent traveled,    but they are afraid they have them since they saw things on the    internet.  
    According    to a representative of the bed bug canine detection agency    ATN, two-thirds of calls to exterminators during the present    period of panic are quickly dismissed. Callers think theyve    got a bed bug infestation, but they really dont. Moreover,    many of the posts on social media depict insects that clearly    are not bed bugs. Frances Transport Minister Clment Beaune        said in early October that of all of the bed bug reports    that were checked zero are proven.

    In the past a bus traveler may have sat next to one and not    paid much notice. But now, Parisians are hyper-aware of any    bug, especially while on public transport and in public places    like the cinema  and low and behold, people are seeing them    everywhere, Bartholomew explained.  
    As Brooke Borel, author of Infested: How the Bed Bug    Infiltrated Our Bedrooms and Took Over the World, recently        reminded readers in an article at Scientific    American, there was another bed bug panic in New York City    back in 2010.  
    According to     estimates from Frances national pest control trade    association, there has been a 10% uptick in calls to    exterminators this year, but this slight jump was expected. Bed    bug populations crashed during COVID-19 when nobody was    traveling, so a     population spike was inevitable when things opened up. The    insects also increase in prevalence when the weather is hot and    humid and in places where people frequently travel. This year,    France, and especially Paris, saw lots of both.  
    French fears of bed bugs were seemingly given credence earlier    this year when a government     report revealed that one in 10 households had bed bugs    between 2017 and 2022. That might seem bad, but this rate is    actually     lower than in the United States.  
    Bed bug populations have grown     significantly since the 1960s, when they were virtually    eliminated in developed countries through the widespread use of    the insecticide DDT. DDT is no longer widely utilized because    of its negative, downstream environmental effects. At the same    time, bed bugs have developed resistance to other insecticides.    Global travel has also drastically increased in the prior    decades, allowing bed bugs to hitchhike near and far. So the    21st century has been a bit of a renaissance for the parasites.  
    Bed bug fear in France is sure to abate as media sources change    their frenetic focus, but it does seem to be spreading to    South Korea. Local reports are full of stories about bed    bug sightings in subways and people flocking to public health    centers to have their insect bites checked.  
    Is it possible that Parisian travelers brought bed bugs to    Korea? Certainly. But its more likely that the social panic    has just moved on. Fear    spreads much more easily than bed bugs.
