Pour atteindre l'objectif, l'invention comprend : un outil de type à évaporation thermique pour la lutte contre les insectes nuisibles avec une partie contenant un agent de lutte contre les insectes (1) qui contient un agent volatil pour la lutte contre les insectes nuisibles, une partie d'accueil (2) qui accueille la partie contenant un agent de lutte contre les insectes (1) et à partir de laquelle l'agent de lutte contre les insectes peut être libéré, et une partie de chauffage (3) qui est fixée à au moins une face latérale de la partie d'accueil (2) et contient une composition produisant de la chaleur (31) enfermée à l'intérieur, ladite composition produisant de la chaleur produisant de la chaleur lors de son exposition à l'oxygène ; et un outil de type à évaporation de chaleur pour la lutte contre les insectes nuisibles dans lequel, dans la partie d'accueil (2), un ou des trous de ventilation (211), ledit ou lesdits trous de ventilation réalisant la communication entre l'intérieur et l'extérieur, sont formés sur une face de la partie d'accueil (2) opposée, par rapport à la partie contenant l'agent de lutte contre les insectes (1), à la face latérale de celle-ci fixée à la partie de chauffage (3) et/ou sur la même face de la partie d'accueil (2) que la face latérale de celle-ci fixée à la partie de chauffage (3).
