The ABS ultrasonic repellent 6060122 from Nature works on European water voles and moles equally, and is equipped with a solar-powered battery that has an operating life of 14 days when fully charged.

It produces an ultrasonic sound every 30 seconds. As their hearing is very sensitive to ground vibrations, the voles and moles are bothered by ultrasound transmissions, as these simulate the presence of predators.

The device should be pushed into the ground near the entrance of the molehill.
