Rodent Repellent
Ultrasonic Repellers are electronic transmitters of high frequency sound (well above the 20 kHz frequency which is the upper limit of the hearing range of the human ear). They emit intensive sound at high decibel levels (sound pressure) that is audible and painful to pests but is inaudible and harmless to humans. The pests will usually leave the area being protected by the ultrasound. They do not get killed.
The powerful sound waves generated by the transducers of repellers are within the hearing range of many pests and cause them pain and discomfort. Sometimes they will leave the area being protected immediately, in other cases it will take as long as two to three weeks before significant reduction in infestation occurs.
Location of Ultrasonic Repeller
The unit should be located that it pints at the area to be protected. Usually, it is best to mount it (with the bracket and bolt provided) on a wall on in a corner 3 to 10 feet off the floor and pointing downward at an angle. It also may be set on a table, shelf or corner and pointed slightly down.
Aim the Master unit at an angle to the wall so that the sound will “bounce around” and will be present throughout the area. Since ultrasound usually does not penetrate walls, it is important that it bounce around corners to cover larger areas. Plug the Master unit into a 230 volts standard wall outlet. Extension cords may be used if necessary. The red light (LED) will go ON and OFF to indicate that the unit is working. Leave the Master unit ON 24 hours a day.
It can be used indoor as well as outdoor. If used outdoors they should be protected from weather. Outdoors, because there are fewer possibilities for reflection of the ultrasound and many things that will absorb or dampen sound, their use is limited. They should be pointed at the area to be protected such as loading docks, doorways, patios and other specific problem areas.
Area of Effectiveness
A single unit will protect an area of 300 sq.ft. in the work place or cabin. In the areas of the false ceiling/ flooring the additional transducer will protect an area of 150 sq. ft. Under difficulty conditions, the size of the area can be considerably less. The type of structure, contents and partitions may limit the area of effectiveness. Since the areas that should be protected are those where food and water are present or the point where the pests enter the area it is usually necessary to protect more than one area in the average place. Important considerations are the cleanliness of the area, the means of entry for pests (easy or difficulty), protection of food present in the area, and the availability of alternate source of food and water.
