The story begins with his own experience, on the terrace of Dominique Hauptmann, founder of BioBelt: it is 2009 and tiger mosquitoes are beginning to sweep through the Côte d'Azur, including Saint-Paul de Vence where he lives. He decided, together with an engineer friend, Gérard Benbassat, who later became his partner in the company, to test most of the individual capture devices available on the international market, the first models of which date back to the 1990s in the USA. A series of experiments over two years enabled them to observe that the luring strategy adopted by these individual devices was effective, with more or less significant catch rates, depending on the model, confirming an observation already mentioned in a number of scientific articles. However, these analyses also confirm what some studies have already pointed out: when carbon dioxide is emitted, whether by breathing people or by a capture device, the attraction of the mosquitoes can last up to 70 metres, in the form of corridors of carbon dioxide molecules transported by the movements of the air.
