Isotronic
Effective marten repellent with ultrasound & flashing light - 230V mains operation for permanent protection, drives martens away gently & reliably

Reliable protection: Mice and other rodents can cause considerable damage in attics, cellars or tool sheds. To drive the animals away without harming them, this device emits ultrasonic sounds in the range of 12-23 kHz every 15 seconds. This sound frequency is unpleasant for the animals, causing them to leave the area. In addition, light signals are also emitted, which act as a kind of flashing light to reinforce the scaring effect.

Ready for immediate use: The device can simply be plugged into a normal socket and is immediately ready for use.
