Marder free in rooms by acoustic signal. The Marderabwehrgerät produces a very high Sinuston with approx. 12 kHz, for humans almost not audible. This frequency is felt by the marten as highly unpleasant. He will avoid this area. For use in dry areas or weather-protected areas such as carports, roofing basements etc. Also provides protection against rodents.
