Ultrasonic waves are sound vibrations with frequencies above 20 kHz, beyond the upper limit of human auditory perception. Piezoelectric ceramics or magnetostrictive elements convert electrical signals into rapid mechanical oscillations, producing acoustic pressure variations that travel through air and solid media.

Droppings and urine stains provide the most reliable evidence of rodent activity inside a residence. Fresh droppings appear as small, dark pellets, typically 3‑5 mm long, with pointed ends. Older deposits darken and may become brittle. Urine stains are invisible to the naked eye but can be detected by a faint, musty odor or by using a blacklight, which makes the spots fluoresce bright green.

Rodents serve as vectors for a range of pathogens that affect human health. Direct contact with rodent saliva, urine, or feces can transmit bacterial infections such as leptospirosis, salmonellosis, and hantavirus pulmonary syndrome. Inhalation of aerosolized particles from contaminated dust may lead to respiratory illnesses, including allergic alveolitis.
