Patent

CA 2489273

The present invention relates to a device for the extermination of pests like e.g., worms and arthropods such as insects and wood-louses, mites, etc., wherein said device is provided with a nozzle arranged to distribute carbon dioxide in solid state to create an atmosphere comprising of carbon dioxide and wherein said nozzle is adapted to achieve a predetermined particle size and velocity of said carbon dioxide adapted for the geometry the pest is located into and wherein the particle size and the velocity are optimised for an effective extermination of the pest in question. The invention also relates to methods and compositions for use with said devices.

L'invention concerne un dispositif permettant l'extermination des parasites, tels que, par exemple, les vers et les arthropodes, tels que les insectes, les cloportes et les mites, etc.. Le dispositif décrit dans cette invention est pourvu d'une buse conçue pour diffuser du dioxyde de carbone à l'état solide afin de créer une atmosphère constituée de dioxyde de carbone. Cette buse est conçue pour permettre l'obtention d'une granulométrie et d'un débit prédéterminés du dioxyde de carbone pour s'adapter à la géométrie de l'emplacement dans lequel le parasite s'est logé. La granulométrie et le débit sont optimisés pour permettre une extermination efficace dudit parasite. La présente invention concerne également des procédés et des compositions utilisables avec de tels dispositifs.
