The invention relates to a method and a device for combating pests living in the earth, especially termites. The aim of the invention is to produce a method and a device wherein at least the fertility of the pests and optionally the laying of eggs is destroyed in a reliable manner using microwave energy which is relatively economical and avoiding harmful consequential effects on humans. The aim of the invention is achieved by using an underground cavity locating method in order to detect nests arranged primarily in the earth and by subsequently drilling a hole in the surface of the earth descending as far as the located cavity. An antenna connected to a microwave generator is then introduced into the hole as far as the located cavity, whereupon microwave energy is radiated via the antenna into the earth in the area around the located cavity. The invention also relates to a device for combating pests living in the earth.

L'invention concerne un procédé et un dispositif pour lutter contre les animaux nuisibles vivant dans le sol, en particulier les termites. L'objectif de l'invention est de fournir un procédé et un dispositif permettant de détruire de manière sûre au moins les animaux nuisibles capables de se reproduire et éventuellement leurs oeufs au moyen d'énergie micro-onde, sans dépenses excessives et sans effets nuisibles pour la santé chez l'homme. A cet effet, le procédé selon l'invention consiste à détecter les nids présents dans le sol à l'aide d'une technique de localisation par repérage des cavités souterraines, puis à creuser un trou allant de la surface du sol jusqu'à la cavité localisée. Une antenne reliée à un générateur de micro-ondes est ensuite introduite dans le trou jusqu'au niveau de la cavité localisée, puis de l'énergie micro-onde est émise dans le sol par l'intermédiaire de l'antenne dans la zone environnant la cavité localisée. Un dispositif correspondant pour lutter contre les animaux nuisibles vivant dans le sol est également présenté.
