Rodent Repellent System generates 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 protected by the ultrasound. They do not get killed.

The powerful sound waves generated by the transducers of Maser 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 a significant reduction in infestation occurs.

Features :
A single Maser 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 difficult conditions, the size of the area that will be protected can be considerably less. The type of structure, contents and partitions may limit the area of effectiveness.

Important considerations are the cleanliness of the area, the means of entry for rodents (easy or difficult), protection of food present in the area, and the availability of an alternate source of food and water. Try one Maser in the area you wish to protect. Within two or three weeks, or sooner, you should see a reduction in pest activity (sightings of rodents and droppings, and damage). If not, you may need one or more additional units.
