Ultrasound is a common method of killing rats. This method disturbs the nervous system of rats by sending out high-frequency sound waves, so as to achieve the purpose of killing rats. However, whether ultrasound is effective in killing mice is still controversial.
Some studies have shown that ultrasound can have a certain interference effect on mice, but this effect is not very obvious. Some mice can adapt to the frequency of ultrasound and will not be affected by it after a period of time. In addition, the effective distance of ultrasound is also relatively limited, and it can only work in a relatively small area.
In addition, there are some other problems with ultrasound killing mice. First, ultrasound may have an impact on other animals or humans, especially those who are sensitive to high-frequency sounds. Second, ultrasound does not kill the mice, but only allows them to escape from the current area. If no other measures are taken, such as blocking the entrance of the mouse or using rat poison, the mouse will probably return to the original area again.
Therefore, although ultrasound is an environmentally friendly and non-toxic rodenticide, its effect is not very obvious, and there are some other problems. If you want to kill rats, you'd better take other methods, such as using rat poison, sticky rat board, etc.
