One setting has higher frequencies to affect small insect pests, while the second setting can be used for mice and other larger pests. This creates a very uncomfortable environment for pests, driving them from their hiding places within your home. Simply place the unit in a location of the room where the ultrasonic waves can be projected in a straight line. An effective ricochet pattern can be obtained by bouncing the waves off reflecting objects such as walls and wood furniture. Placing another unit on the opposite side of the room will increase the effective coverage and eliminate Sound Shadows.
Ultrasonic waves travel in a straight line, just like audible sounds.
These waves fill a room by bouncing off non-absorbing materials. Sound absorbing materials such as soft furniture, drapes and carpeting will reduce the range of PestContro Ultrasonics. Therefore, these Shadows may occur in corners where sound waves cannot hit. The ultrasonic sounds may affect rodent pets such as hamsters, gerbils and rabbits. However , if you position the unit away from the rodent pets, it may not cause them discomfort.
