Homes evacuated as floods hit village in French Alps

More than 50 people had to be evacuated from their homes in a village in the French Alps as violent storms struck the south-east of the country.

Less than four years after storm Alex struck the Boréon area of the Alpes-Maritimes département in September 2020, leading to 10 deaths, it was once again hit by severe weather, as the storms combined with high-altitude snow melt caused the Vésubie river to burst its banks.

The 1,400-population village of Saint-Martin-Vésubie, which was cut off from the rest of the country by the devastating 2020 storm, was again affected by severe weather.

Thierry Ingigliardi, the village’s deputy mayor in charge said: “Everything is being destroyed, we’re suffering the loss of roads yet again.” 

As a precaution, 52 people, including four children, were evacuated to a community hall.

But there was some confusion over the scale of damage caused by the flooding, after current Interior Minister Gérald Darmanin posted a message on X, formerly Twitter, saying that bridges had been washed away in the flooding. 

“None of the bridges are threatened, two fords have been washed away,” Gaël Nofri, deputy mayor of Nice, clarified on the social network.

But at least two bridges have been damaged, leaving around 20 homes cut off, while two other structures are still ‘under surveillance’, as the local council reported earlier. The latter also deplored “temporary infrastructures that are not holding”.

Hugues Moutouh, prefect of the Alpes-Maritimes region, told BFMTV: “Everyone is annoyed (…) It’s been going on for months now, we’re using temporary structures.”

Moutouh says he did not want “to come here again to see how powerless we are” when seasonal storms known as épisodes méditerranéens return in autumn. 

The storms in the Alps led to ‘once-in-a-century’ flooding in the Vaud canton of Switzlerand. Around one month’s rain fall fell in just an hour and caused major flooding in the town of Morges, which stands on the banks of Lake Geneva.

LIVING IN FRANCE

What are anti-mosquito apps and are they worth using in France?

Anti-mosquito smartphone apps are something of a summer hit in France – but how sound is the science behind them?

What are anti-mosquito apps and are they worth using in France?

Summer in France is mosquito season. The insistent high-pitched biting pests can be a huge frustration on sultry evenings, and are a major source of revenue for pharmacists and supermarkets selling repellents, creams and insecticide sprays, to those unfortunates who provide a tasty snack for the itch-inducing insects.

Recently, efforts to prevent mosquito attacks have moved into the app sphere. A number of smartphone applications are available that claim to repel mosquitoes by emitting low-frequency sounds from the phone’s speaker.

The idea isn’t new. And it is based on actual science. France’s Institut national de la santé et de la recherche médicale (Inserm) said that the apps are intended to, “imitate the sound waves produced by the wing beats of … dragonflies. Female mosquitoes, which bite humans, would be repelled by this sound”.

So far, so good. The theory seems sound enough.

But there’s a problem. 

“The [sound]waves that could possibly be heard by female mosquitoes are too powerful to be reproduced by a smartphone,” Inserm went on to say.

Possibly to cover themselves, the Anti-moustique insecticide app, available on the App Store, states in its own description: “It has not been scientifically proven that low-frequency sounds can help repel mosquitoes. For this reason, this app should be considered a joke app”.

According to Inserm, experts advise against this type of app, “at best because they are useless, at worst because they can provide a false sense of protection”, leading users to neglect other – rather more effective – approaches to protecting themselves from bites.

Anti-mosquito advice

When it comes to repelling the horrible little bastards, the French government does have some official advice.

The main thing is to have as little stagnant water around as possible – since this is where mosquitoes breed.

This includes regularly emptying vases, flower pots, as well as watering cans and pots. If you want to collect rainwater, you could cover water butts with mosquito nets or fabric to keep the mosquitoes from getting inside.

To protect yourself, try to wear long, loose and light-coloured clothing, and use a good quality insect repellent. You might also consider wearing a mosquito net head gear.

A plethora of products exist on the market, from machines that also produce the mosquito repelling noise to scented candles or smoke coils, most of these have at at least some effect, but are unlikely to keep the mossies away entirely.
