A device for acoustic rodent control, comprising a diffuser (11) constituted by a contoured solid of revolution that is provided, in a downward region, with a cavity in which a piezoelectric element (16) is applied, the piezoelectric element being controlled by an electronic board (19) contained in a box-like body (17) that supports the diffuser. The electronic board (19) supports an electronic circuit that comprises means for detecting the vibratory state of the piezoelectric element. |
