In daily life, many people use mosquito coils or anti-mosquito patches to repel mosquitoes, but they don’t know much about ultrasonic mosquito repellents, especially its characteristics. What are the advantages and disadvantages of the ultrasonic mosquito repellent?
1. Advantages:
It is harmless to human body, safe and non-toxic. Because it uses the means of radiating ultrasound and audio to imitate the sound and frequency of the dragonfly, which can kill mosquitoes, to achieve the mosquito repellent effect. It is safe, non-toxic, non-radiation, completely harmless to humans and animals, and has no chemical residues. It is an ideal companion for home travel, fishing, camping, barbecue, reading, dating, mountaineering, farming, and taking a cool place. It can also be placed in cats. Beside the dog, drive away mosquitoes.
2. Disadvantages:
1. Ultrasonic mosquito repellent does not have a particularly obvious effect. The effect of mosquito repellent is not as good as mosquito repellent water or mosquito coils, and its function is not as good. Moreover, its price is relatively not cheap, and if you buy it, it has the effect of not worth the loss.
2. The radiation area is too small. Because the power is too small, it can only cover a radius of 1.5 meters with the mosquito repellent as the center, and the mosquito repellent effect is not good.
3. Inaccurate setting of high-frequency sound wave threshold. Animals have different sensitivity to high-frequency sound waves.
