Bites, origin, proliferation eight questions not so stupid on bedbugs

The government is launching a plan to combat bedbugs.In a statement published Thursday, February 20, the Minister responsible for housing details how he intends to fight these insects whose bites cause itching and which develop in mattresses and sheets, as well as furniture and corners.Julien Denormandie, Minister in charge of VSity and Housing, provides for an information campaign as well as a parliamentary mission to change the law in the face of the resurgence of these parasites, the ministry announced on Thursday.

While they had practically been eradicated in France in the middle of the 20th century, the ministry notes an upsurge, from the figures raised by professionals in the extermination of parasites.The government is therefore launching this Friday an information campaign, with a telephone number (0.806.706.806) and a site (stop-punaises.gouv.fr) dedicated.He also intends to ask professionals to structure themselves, with a label and a key training, and evokes the upcoming launch of a mission in the National Assembly.

Back in eight questions about these unwanted insects formerly eradicated, and which would already be present in 400,000 sites in France, according to the Association Right for Housing.

Where do bedbugs come from?

They often spread during travel "through clothing or luggage," said the site of the Ministry of Health.Bedbugs can circulate in unsuccessful and very narrow places, such as a slit in the thickness of a credit card.

Shakes, garage sales or flea markets, of which we think less, are also a possible source of infestation.We can bring back bedbugs "because we bought flea markets", reports to France 3 Nouvelle-Aquitaine Aurélie Lecointre, head of the health and social life service at the town hall of Limoges.The ministry therefore advises to "inspect carefully and [to] clean these items before installing them in your home".

Where do they take refuge?

Bedbugs "can enter everywhere, even in the cleanest houses and hotels," says the Quebec government site devoted to this public health problem.In general in dark places, they can be found in "the bedroom and the places of life, the cracks of the walls, the floor and the furniture, the seams of the curtains, the electrical sockets, the plinths, the moldings",lists the site of the town hall of Paris.

They are often close to where they can feed on human blood, that they join at night.However, the bed bug "cannot easily climb on metal or polished surfaces, even less flying or jumping," added the Ministry of Health.

Another clue encouraging distrust: bedbugs also leave small black spots on sheets, mattresses or walls, which come from their excrement, or long traces of blood on the sheets "due to the crushing of the bedbugs during thesleep of the person, "describes the ministry.

Are their bites dangerous?

The bedbugs, who sting the sleepers at night by pumping blood, "do not transmit disease", specifies France 3. But their bites can cause severe itching if their number is large.The traces disappear "naturally within ten days and do not require special care", specifies the ministry, which then advises to "clean [your] skin and not to scratch yourself to avoid infection".

The presence of these insects can also cause depression problems.A person affected by an infestation has five times more symptoms of anxiety and sleep disruption than a non-attempt, according to the American Journal of VSase Reports (link in English)."I had crises of tears and anxiety, I was no longer sleeping at night, it was the horror," said a resident affected for the Figaro.
