They can damage furniture, goods and food, consequently giving serious problems both from economical and company's image point of view. In addition, they are diseases carriers, very dangerous to human beings. 

HACCP guidance imposes the use of ecological and bloodless rodents control. Therefore, Zernike designed a simple seismic repeller, able to reject mice and rats without use of polluting, expensive and dangerous to operators chemical products. Derat issues seismic and random variable vibrations, which prevent rodents from getting addicted to vibrations themselves.

In the installation of rodents control, the seismic repeller can be combined with our ultrasonic repellers U120 and U360, in order to cover critical areas, such as pedestrian areas or loading and unloading areas.
