1What is ultrasound?

   Answer: When an object vibrates, it produces sound. Scientists measure the number of vibrations per second as the frequency of sound, which is measured in hertz. When the vibration of an object exceeds a certain frequency, which is above the human ear's hearing range, people cannot hear it. Such sound waves are called "ultrasound." The human ear's hearing range is 16 Hz to 20 kHz. Although humans cannot hear ultrasound, many animals have this ability. Bats can emit ultrasound with frequencies of 2 to 100,000 Hz to hunt for food or avoid dangerous objects, which is like an active "radar station." Bats use this "radar" to find targets and catch insects. It was not until the first World War that humans learned to use ultrasound, which is to use the principle of "sonar" to detect targets and their conditions in water, such as the location of submarines.

   Ultrasound has characteristics such as being unable to penetrate obstacles, having strong directionality, short propagation distance, and rapid attenuation. The propagation of ultrasound is achieved through the reflection of surrounding objects countless times, forming a ultrasound protection net that covers the entire preventive and therapeutic space.

2. What is an ultrasonic pest repeller?

   Answer: Ultrasonic mouse repellent is a device that uses specialized high-frequency acoustic pulse circuit technology, and has been developed through years of research by the scientific community on the auditory senses of mice. It can produce ultrasonic waves at 13kHz-55kHz. The ultrasonic waves produced by this device can effectively attack the auditory systems of mice and cause physiological dysfunction. This technology is based on advanced pest control concepts from Europe and the United States. The purpose of using this technology is to create a quality space without mice and pests, to create an environment where pests and mice cannot survive, forcing them to migrate automatically, and preventing them from breeding and growing within the scope of prevention and treatment, achieving the goal of driving away mice and pests.

3. Can ultrasonic waves really drive away parasites?

   Answer: Animals such as mice and bats communicate using ultrasonic waves. Mice have very developed auditory systems and are very sensitive to ultrasonic waves, allowing them to judge the source of sounds in the dark. Young mice can emit ultrasonic waves at 30-50kHz when threatened, even before they open their eyes. Adult mice can emit ultrasonic waves to call for help in crisis and to express happiness during mating. It can be said that ultrasonic waves are the language of mice. Therefore, it is possible to use high-power ultrasonic waves to effectively interfere and stimulate the auditory systems of insects, making them unable to bear it and feeling panic, unease, and twitching symptoms, thus achieving the purpose of driving away mice and preventing and treating the scope.

4. Why didn't the insect repellent I bought before work?

Answer: There are several possibilities that may affect the effectiveness of use:

   The first type is related to the layout of goods, room partitions, or the distribution of items (obstacles). If the density of items in the prevention and control area is too high, or if goods are directly piled on the ground, or if there are too many dead corners or partitions, such an environment should increase the number of use of pest repellent devices, and it is necessary to have high-energy ultrasonic coverage to achieve the effect of pest control.

   The second reason is closely related to the placement of the pest repeller. If the position of the repeller is not well placed, and there are fewer reflection surfaces, it will also reduce the effectiveness of the repeller. It should be placed as much as possible in a place that can produce more reflection and refraction waves. The third reason is that the space is too large for prevention and treatment, and the number of pest repellers is not enough to cover the comprehensive prevention and treatment range. If the repelling effect is not ideal, it should also increase the number of pest repellers to strengthen the density of ultrasonic attacks to achieve the most ideal repelling effect.
