The human ear can hear at a sonic frequency below 20000Hz. Ultrasonic sounds have frequencies higher than 20000 Hz. Cats and dos are able to detect ultrasonic frequencies up to 27000 Hz. This unit operates above 27000 Hz and thus in most cases will not affect cats or dogs. Effectiveness of ultrasonic devices will vary depending on the severity of the infestation. In some cases, over time, certain rodents may become accustomed to the ultrasonic sound and may return to their nesting areas even in the presence of an ultrasonic product. Unclean areas will retain a strong attraction to pests despite the presence of an ultrasonic pest repellant. Ultrasonic waves cannot penetrate through floors, ceilings, walls or doors.
