Are electronic mosquito repellents really useful? How do electronic mosquito repellents work?

Electronic mosquito repellent is a very common product on the market. Many people have used it, but some people think that it is useless. So let's find out whether electronic mosquito repellent is really useful? How does the electronic mosquito repellent work?

Electronic mosquito repellents are ineffective. In fact, there are indeed "ultrasonic mosquito repellents" on the Western market, but those things imitate the sound of bats. Bats use ultrasound to locate prey. In order to resist predation by bats, some insects have evolved organs that can recognize ultrasound and can escape after hearing the sound of bats. Suppose those electronic mosquito repellents that imitate bat ultrasound are really effective. The frequency of sound waves emitted by bats is at least above 10kHZ, and can even be higher than 100kHZ. Therefore, if these "mosquito repellents" are effective, they must be able to emit sound waves that include ultrasonic frequency bands. For the human body, long-term and large doses of ultrasound may cause damage to human cells.

Electronic mosquito repellents use acoustic resonance technology, which generates low-frequency pulse sound waves through high-frequency oscillation of ultrasonic waves. They can imitate the sound of dragonfly wings flapping to repel mosquitoes. This destroys the mosquito's perception system and makes it lose its ability to find food and suck blood. When using an electronic mosquito repellent, be careful to take out the battery if it is not used for two months. The electronic mosquito repellent should be installed 20-100 cm from the ground and plugged into a power socket perpendicular to the ground. The installation point should be avoided as much as possible from sound-absorbing materials such as carpets and curtains to prevent the reduction of sound pressure from reducing the sound range and affecting the insect repellent effect. When using an electronic mosquito repellent, pay attention to moisture-proof and waterproof, so that the electronic mosquito repellent can be used longer and the effect will be better.

1. Kelitai electronic mosquito repellent. Kelitai electronic mosquito repellent adopts physical mosquito killing method, which is non-toxic and harmless to human body; it kills mosquitoes efficiently, quickly and saves time, and the mosquito killing rate is as high as 98%; it also has humanized treatment to reduce noise, which does not affect the user's sleep; it has a wide range of applications.

2. Royal Baby 6th Generation Mosquito Repellent. Royal Baby 6th Generation Electronic Mosquito Repellent (blue) adopts the principle of multi-frequency oscillation wave and has a unique volume adjustment design. When used outdoors, the volume can be turned up to enhance mosquito repellent prevention; when used in sleep mode, the volume can be turned down to avoid affecting sleep quality. The volume can be freely adjusted in different environments to meet your requirements. The sound frequency adopts a multi-frequency design to make the mosquito repellent more types and more effective.

3. Grand portable mosquito repellent. Grand portable mosquito repellent uses the principle of electronic oscillation waves, has no chemical ingredients, is environmentally friendly and pollution-free. It has three timer settings and imported IC from the United States, and has a significant mosquito repellent effect. It is currently recognized as the safest way to prevent mosquitoes, completely harmless to the human body, and suitable for infants and pregnant women. The automatic radio wave mosquito repellent is non-toxic, chemical-free, and environmentally friendly. It uses the principle of physical mosquito repellent, is smokeless, has no irritating odor, and is healthy. It is small and exquisite in appearance, fashionable and novel, and easy to carry.

4. Bikanuo electronic mosquito repellent. Bikanuo electronic mosquito repellent uses the principle of shock wave, which will not cause harm to the human body and has no side effects. The three-stage timing device setting (4H, 6H, 24H) is energy-saving and convenient. It uses a single battery, which is included in the product.

Electronic mosquito repellents that are quality-assured and have passed the inspection of the Quality Supervision Bureau are harmless to the human body. The working principle of the electronic mosquito repellent is to use the acoustic resonance technology. The sound intensity of the ultrasonic waves emitted is extremely low, below 45 decibels acceptable to the normal human body, and has no effect on the human body. The electronic mosquito repellent uses the technology of ultrasonic high-frequency oscillation to generate low-frequency pulse sound waves, emitting sound waves that can interfere with mosquitoes. Mosquitoes are more sensitive to the sound waves, and the mosquitoes' perception system is damaged, thereby achieving the effect of repelling mosquitoes. When using the electronic mosquito repellent, you can also hang it on your clothes, which can also achieve the effect of repelling mosquitoes.
