Doubts about electronic insect repellent

What is ultrasound?
   Answer: when the object vibration sound, when beyond a certain vibration frequency of the object, which is higher than the human ear hearing range, people listen to not to come out, so the sound waves is called \"ultrasonic\", although said that humans cannot hear ultrasonic, but a lot of animals have the ability, 2 ~ 100000 hz bats emit ultrasonic hunting for food or avoid dangerous objects,   Ultrasonic wave has the characteristics of being unable to penetrate obstacles, strong directivity, short transmission distance and fast attenuation.

2. If the mouse-repellent device has been used for a long time, will the mice become adaptive and ineffective?
    A. no. The automatic frequency sweep of the microcomputer produced by this product is constantly changing at intervals, so that pests such as rats will not have \"adaptability\" and \"resistance\" to a fixed frequency.
What is an ultrasound rat driver?
   A: the ultrasonic mouse drive is a device that can produce 20khz-55khz ultrasonic waves by using professional high-frequency sound wave pulse circuit technology and years of scientific research on the rat hearing. The ultrasonic waves generated by this device can effectively attack the rat hearing system and cause the rat physiological dysfunction. This technology comes from advanced pest control concepts in Europe and the United States. The purpose of this technology is to create a quality space free of mice and pests, create an environment where pests and mice can't live, force them to move automatically, fail to breed and grow within the control range, and achieve the goal of eradicating mice and pests.
4,Can ultrasound really drive out mice?
   A: rats, bats, and other animals all communicate by ultrasound. Rats have a highly developed hearing system and are very sensitive to ultrasonic waves. They can judge the source of sound in the dark. Carden and Hofer, 1992), comes across The crisis when adult mice in distress, can emit ultrasonic during sex can also emit ultrasonic said happy, to say The ultrasound is The language of rats and mice (foreign references: Fay 1988, Warfield, 1973, and The Nature of The Sound), and therefore can make use of high power ultrasonic in mice interference and stimulating auditory system effectively and make it unbearable, and panic symptoms such as restlessness, stay, convulsions, so as to achieve The aim of prevention and control of The rats away range.
5. Why did the mouse drive I bought before not work?
A: there are several ways that this may affect the use effect:
  The first has to do with the goods such as layout, room partition, or item (obstacles) distribution have relationship, if control zone item put density is too high, or the goods stored directly on the floor, or there is a lot of blind Angle, partition wall etc., this environment should be to increase the number of rat control device to use, must have a high-energy ultrasound coverage can reach the deratization effect.
  The second one has a lot to do with the placement of the mousester. The poor placement of the mousester will weaken the effect of the mousester when the reflector surface is small. It should be placed in a place where more reflection and refraction waves can be generated.
  The third one is that the space for prevention and treatment is too large, and the number of anti-rodent devices used is not enough. If the control range cannot be fully covered, the anti-rodent effect will not be ideal. In this case, the number of anti-rodent devices should be increased, and the density of ultrasonic attack can be strengthened to achieve the anti-rodent effect.

6. How long before the effect of the rat and insect repellent can be shown?
A: after about two to six weeks of correct use, this product starts to show its effect. The rats, pests and so on will be significantly reduced. If there is one or two occasionally, you don't have to worry.
