This ultrasonic generator produces very loud and aggressive ultrasonic sounds that pulse like a siren, which many animals perceive as extremely unpleasant and therefore try to avoid as much as possible (very often, but not always!).

The generator is used to prevent rodents, insects, reptiles, wildlife, and birds. If larger areas are exposed to ultrasound, you can connect up to 2 additional L020 speakers (not included). The sound frequency can be adjusted between ultrasonic (which is inaudible to humans) and loud + high sounds that can also be heard by people.
