P-I car rodent repellent

Advanced car rodent repellent - a new technological invention that is the safest, most convenient, and most effective in eliminating rodent damage to cars.

Powerful and efficient - cars parked at night often become a playground for mice, and the wires, oil pipes, and other equipment inside the car are often bitten off by mice, causing the car to not work properly. Nowadays, mouse repellents can emit a series of uninterrupted ultrasonic frequencies to stimulate the hearing of mice, making them fearful and fleeing the car, thus preventing the car from being harmed by mice.

Safe and reliable - This device does not contain any chemical materials or equipment, and will never have any adverse effects on other devices or appliances. In addition, the hearing and sensitivity of mice are hundreds of times higher than that of humans, and human hearing can only be between 50-20000Hz frequencies. The ultrasonic horn of this device emits ultrasonic waves with frequencies higher than 32000Hz to drive away mice and continuously convert to high frequencies, making it difficult for mice to get used to and eliminating any adverse effects on humans. It is very safe and reliable.

Easy to use - fastened to the most vulnerable location on the vehicle body, the red lead is connected to the "+" pole of the battery (12V DC), and the black lead is connected to the "-" pole of the battery. When the light is on, the rodent repellent will take effect.
Attention - This device needs to be continuously powered on for a long time, with a power consumption of less than 25 milliamps (which will not affect the normal operation of the battery) and an effective area of 8 square meters. This device is also suitable for use in other advanced electrical appliances that are susceptible to rodent infestations.


The usage method of the product is as follows: the product is connected to the inside of the car head, and the wire is connected to the battery inside the car head. It is best to install it in the center of the car trunk as much as possible, as the effect will be more obvious. The red wire is connected to the "+" pole of the battery (DC 12V), and the black wire is connected to the "-" pole of the battery. When the light is on, the mouse drive will take effect. You can do it yourself or go to a car repair shop or beauty car shop to get it done.

Five Additional buyer precautions:

(1). Place this product in the front compartment of a car, preferably not in contact with water, a little bit is acceptable.
(2). Before use, make sure to confirm that the power supply is a 12V DC dry battery.
(3). This product can be placed inside the carriage with the window facing outward, preferably installed in the center, and secured in place with screws.
(4). This product can take immediate effect after use. But the best results can only be seen after continuous use for one week. At the beginning of use, there may be a small occurrence of mice becoming more active. This is a manifestation of mice being stimulated, which can cause them to wander around and disappear after a period of time.
Even if some mice cannot escape temporarily, they will become lethargic, lose appetite, and lose their reproductive and destructive abilities.

6、 Specifications:

Power supply: 12V DC;
Sound wave frequency: above 32000Hz;

Scope of work: 8 square meters

The frequency of the ultrasound generated by this product is beyond the range of human hearing, targeting mice in the frequency range, so humans cannot hear sound. So it is absolutely harmless to the human body.
Suitable for: various types of cars: private cars, bread, trucks Wait, the effective range is 8 square meters.

7 'Drive' is more positive than 'kill':
The research conclusion of American experts is that there is a certain amount of "support" in a certain space. Killing a pest will result in the birth or invasion of new pests. And pests can never be completely eradicated. If insect repellents are used to deteriorate the living environment of pests and reduce the "feeding amount", there will be no new pests born or invading. So, 'killing' actually stimulates the reproduction of pests, while 'driving' actually inhibits the reproduction of pests. Therefore, "deworming" is more effective than "insecticidal"
More positively significant.

To avoid rodent infestation, based on the advice I have heard and the advice of the mechanic, I would like to summarize:

1) Do not park your car in areas with dirty surroundings, such as near garbage dumps;

2) Don't keep the car off for a long time, try to start it every day;

3) After ignition, wait for half a minute and then drive forward

*Kind reminder: This product is a long-term rodent repellent device and not a hunting tool. The duration of onset varies depending on the degree of rodent damage, and generally takes 5-7 days to take effect.

Question: What is ultrasound?

Answer: What is ultrasound? The auditory range of the human ear is from 16Hz to 20000Hz
Any sound wave above 20kHz is defined as ultrasonic, as we cannot hear these sounds at all. The frequency of sound waves below 16Hz is called infrasound, and elephants can emit infrasound to communicate with their companions several miles away. Ultrasonic waves have the characteristics of being unable to penetrate obstacles, strong directionality, short propagation distance, and fast attenuation.


Q: Can ultrasound really drive mice away?


Answer: Animals such as mice and bats communicate through ultrasound. Mice have a highly developed auditory system and are very sensitive to ultrasound, able to determine the source of sound in the dark. Young mice can emit ultrasound waves of 30-50kHz when threatened, and can return to their nest by emitting ultrasound waves and echoes before opening their eyes (foreign reference: Allin
and anks1971； Carden and Hofer
In 1992, adult mice can emit a type of ultrasound to call for help in times of crisis, and can also emit ultrasound to express happiness during mating. It can be said that ultrasound is the language of mice. The auditory system of rodents operates between 200Hz-90000Hz (foreign reference: Fay
1988,  Warfield 1973, and The Nature of
Sound)， If a powerful high-power ultrasonic pulse can be used to effectively interfere with and stimulate the auditory system of rodents, causing them to become unbearable, panic, and uneasy, exhibiting symptoms such as loss of appetite, escape, and even convulsions, the goal of driving the rodents out of their range of activity can be achieved. So it has been experimentally proven that ultrasound can indeed have a driving effect.
