In principle, sound is a commonly used method to repel rats. Record the ferocious screams of cats, dogs, owls and other rat-catching animals, or record the screams of rats, or record various sharp sounds, and then use a playback device to play them in places where rats are infested, and you can scare them. Run the mouse. Some mice are very smart. If they use a sound for a long time, they can detect it. Therefore, various sounds can be used alternately to prevent the mice from getting used to it.

The above method has certain limitations, because various sounds are within the hearing range of the human ear and often interfere with people's work and rest. It is more suitable for warehouses where no one is on duty and where people live. Therefore, the environment where people live can use ultrasonic rat repellers to repel rats to prevent them from disturbing the people's daily routine. Note that when using an ultrasonic mouse repeller in a living environment, the power should not be too high to avoid harming the human body.

Rats are also afraid of light stimulation, so light sources can also be used to repel rats. Various camera flashes (you can use filters to change colors) and strong neon lights can be used to repel rats. Set a certain flash interval and change the color every once in a while to prevent rats from developing habits.

Many mice can observe and get used to sound and light sources. Therefore, the above-mentioned sound and light mouse repellent methods often have limitations and will become ineffective after a period of time, and the mice will return to their rampage. Therefore, if you are repelling rats in an unmanned environment, you can use a high-power ultrasonic generator or a strong ultraviolet generator to directly damage and burn the rats, causing them to die soon after escaping and never return.

In addition to sound and light to repel rats, smell is also a good method to repel rats, which can be effective immediately. For uninhabited environments, smoke can be smoked with formalin, sulfur smoke or chili pepper smoke, which not only repels rats, but also damages the rat's internal organs, especially the respiratory tract, making it remember this place deeply and not dare to return again. .

In home and other environments, peppers and sulfur cannot be used because they are harmful to people and livestock. You can use aerosol insecticides instead, which are the ones used to kill cockroaches, termites, ants, flies and mosquitoes at home. , can also effectively repel rats, with immediate results.

A more alternative and effective method is to use rats to help repel rats. You have to catch one or two mice first, then use a strong iron clamp to clamp the tail of the mouse, and then put the mouse in a cage, making the mouse scream so that other mice can see and hear it, so as to scare them away. The mice in the cage can be fed every now and then. If they don't starve to death, there is an environmentally friendly mouse repeller for a long time.

Note: As long as it is to repel rats, one method often cannot be effective in the long term. Therefore, various methods can be used comprehensively.
