How the RODAR II works

RODAR II ultrasonic pest repellers emit high-frequency sound (ultrasound) at sound pressure levels unbearable to pests but at frequencies above the hearing range of humans, cats, dogs and other pets.  RODAR repellers are completely safe.  At sound pressure levels equal to a jet engine at close quarters, RODAR ultrasound creates an environment unpleasant and intolerable to many pests that can sense them.

The powerful sound waves generated by RODAR’s patented transducer are in the hearing range of many pests and cause them pain and discomfort.  Pests often leave the area being protected immediately.  In other cases it may take up to two weeks before significant reduction in infestation occurs.

We have been designing, engineering, manufacturing and field testing RODAR ultrasonic pest repellers for over 30 years.  The new RODAR II is extremely powerful with more than 10 times the power of its predecessor, the acclaimed RODAR J.  And power is what makes the difference – both in size and area coverage and how well it works in any size area.  You need all the power you can get, within safe limits – and RODAR is completely safe.
