A plague of bedbugs has hit Paris and other French cities, provoking a wave of insectophobia and raising questions about health and safety during next year’s Olympic Games.
That’s broadly how the phenomenon has been described in the French – and now international – news media.
In part it is true. But in another part it isn’t.
What is the case is that the number of bedbug sightings has increased over the last weeks – and that that upward trend goes back several years.
In Paris, to the long-standing fear of infestation felt by flat-dwellers (one in 10 of whom have experienced bedbugs in the last five years, according to official figures) have been added new sources of angst.
Reports that punaises have been recently seen in cinemas have not been proven, but are taken seriously. Likewise claims that people have been bitten on trains.
And now both Paris City Hall and President Emmanuel Macron’s government are calling for action. It is a measure of how seriously they take the issue – and of how they need to protect the image of Paris ahead of the 2024 games – that they are not dismissing the bedbug panic as a social media invention.
Because that is also part of the story.
Scare stories are flashing across the internet so fast that they are turning what was once for newspapers a reliable slow-day chestnut into a national emergency.
Cinema-owners – already worried about declining attendance – are seriously spooked when videos circulate showing unidentified mites on a seat. People on metros have started checking their upholstery. Some prefer to stand.
The fact of the matter is that bedbugs are making a comeback, and have been for perhaps 20 or 30 years. But that is not just in France, but everywhere.
There are several factors, of which globalisation – container trade, tourism and immigration – is the most important. Climate change can be ruled out. The bedbug – cimex lectularius to give its Latin name – is a domesticated creature. It goes where humans go. Weather doesn’t come into it.
After World War Two, bedbugs – like many other beasties – were massively reduced in number by the widespread used of the insecticide DDT. But over the years, DDT and many other chemicals have been banned because of their effect on humans.
And in the meantime, the bedbug population has been altered by the elimination of those creatures who were genetically susceptible to chemical eradication in the first place. Those that survived the DDT blitz are the ancestors of today’s breed, who are as a result far more resistant.
A third factor may be the decline in cockroaches, thanks largely to cleaner homes. Cockroaches are a bedbug predator. Fear not: no-one is suggesting reinfesting homes with cockroaches in order to deal with les punaises!
According to Mr Berenger, in the developed world, people are liable to panic about bedbugs because we have lost the collective memory of them. In other parts of the world, they are still common – and people keep the threat in proportion.
The truth is that bedbugs are indeed a menace – but the danger is more psychological than physical. Cimex lectularis may be revolting, but as far as is known it cannot transmit disease. Its bites are loathsome, but they do not last very long.
It sheds its exoskeletons at regular intervals; it leaves faeces in the forms of black dots (digested blood); it wiggles in delight at the scent of a human; and it can last for a year without food. All horrors to contemplate.
