Abstract

L'invention concerne un procédé de capture de moustiques qui comprend les étapes consistant à : agencer un dispositif d'attraction (20) de manière à y placer un attractif pouvant être volatilisé afin de former un appât odorant au niveau d'une entrée d'air (401) d'un dispositif de capture de moustiques (10), attirer un moustique vers la zone du dispositif en utilisant l'appât odorant formé par volatilisation de l'attractif, et ensuite attirer le moustique dans la partie intérieure du dispositif de capture de moustiques (10) par utilisation du flux d'air à pression négative généré par le dispositif de capture de moustiques et tuer le moustique. L'attractif utilisé dans le dispositif d'attraction du procédé comprend trois différentes substances volatilisables, disposées respectivement dans trois espaces isolés les uns des autres, pour former l'appât odorant attirant les moustiques. L'odeur formée par la volatilisation des trois substances différentes présentes dans l'attractif peut attirer des moustiques et insectes vers une zone de fonctionnement efficace du dispositif d'attraction de moustiques, afin de capturer et tuer les moustiques et insectes de manière efficace. L'attractif est non toxique, il ne contaminera pas l'environnement et il peut être utilisé dans une zone d'intérieur ou d'extérieur.
