Ultrasonic mosquito repeller: types (portable, outdoor and others), principle of operation, reviews

Nature has endowed bloodsuckers with a powerful sense of smell, which allows them to sense prey even from several kilometers away. It is this feature that is used in most cases when fighting mosquitoes. These insects also have acute hearing and the ability to detect certain sound frequencies. This fact also made it possible to develop special remedies against bloodsuckers. The sound that repels mosquitoes must be within a certain range for it to be able to recognize it.

Features of the influence of sound

Mosquitoes are representatives of a large family and their numbers are huge.
Each type has not only external features, but also internal ones. This is why different mosquitoes have different degrees of perception of sounds. This explains the fact that for some, ultrasound at 6 kHz is already fatal, while for others it will not even cause slight discomfort. There are different opinions regarding the effectiveness of repelling bloodsuckers using ultrasound. Manufacturers claim that the method works flawlessly and offer new developments of special devices, and scientists are trying to find a reasonable explanation for this. As a result, millions of residents buy various repellers and use them to protect themselves from bloodsuckers.

Ultrasonic mosquito repellers

The main advantages of ultrasonic control:

1. Safe for humans. Repellers do not have to be applied to the body, smeared on the skin, or treated with clothing. As a result, the risk of developing allergic reactions and other serious consequences is eliminated.
2. Reusable. Special repellers are powered by mains or batteries, so they will work for a very long time. After this, you just need to replace the battery and continue using the device.
3. A wide range of. Online stores and retail outlets offer a huge variety of ultrasonic repellers. They can have different dimensions, design and functionality, which makes it possible to choose a device to suit your own taste.

On a note!

You can also make your own mosquito repeller. This will require a minimum of skills, a user manual and a small supply of materials that can be found in the house or will cost a penny.

Among the shortcomings are noted:

1. High price. Ultrasonic mosquito repellers are more expensive than the usual cream or spray.
2. Questionable effectiveness. There is no clear opinion regarding the effectiveness of this method of protection. Scientists have not been able to 100% confirm this fact. Also, the degree of efficiency depends on the ability to choose the right frequency.

Ultrasonic devices are also on sale, which have several operating programs and are capable of repelling not only insects, but also small rodents.

What sounds will repel mosquitoes?

Many studies have been conducted to determine what frequency of sound is needed to repel mosquitoes. But all of them not only failed to identify the necessary values, but also cast doubt on all arguments that ultrasound can help in the fight against insects. The minimum value is 4 kHz, but even this may not apply equally to different fauna.

Employees of one radio station also suggested using ultrasound against mosquitoes. In addition to the musical composition, they included ultrasound. Most adults' hearing aids couldn't pick it up, but the bloodsuckers had to stay away. Music against mosquitoes was supposed to give residents the opportunity to relax quietly in nature or do gardening without annoying midges.

Mosquito repellent sounds

Interesting!

The world-famous home appliance company LG has released a whole series of air conditioners that contain a device for repelling mosquitoes using ultrasound.

The opinion that mosquitoes are afraid of ultrasound has often been used for selfish purposes by many entrepreneurs. Some offered mobile phone users to download a special ringtone, the range of which was supposed to scare away bloodsuckers.

Some developers offered to purchase devices that imitate the sounds of a dragonfly. It is these insects that are one of the worst enemies of bloodsuckers. A dragonfly can eat an almost unlimited number of mosquitoes, which is why they will try to avoid it. But it has been scientifically proven that the sound of dragonfly wings is in the range of 20-170 Hz, which is significantly lower than what the device suggests.

The development of Soviet scientists was especially popular. This is a special multivibrator equipped with a frequency selection function. Thus, users could set a mosquito-killing sound depending on their region of residence.

Interesting!

Mosquitoes have many natural enemies, and some developers have decided to use the croaking sound of frogs to recreate a frightening sound.

Thus, scientists could not find one hundred percent confirmation that buzzing, beeping, croaking or any other sound at any frequency can help fight mosquitoes. It turned out to be even more difficult to find the very range of required sound vibrations. Therefore, to combat bloodsuckers, it is better to use proven and effective mosquito repellents.

Ultrasound against mosquitoes

In their life activities, blood-sucking creatures are guided by a keen sense of smell and ultrasound. Insects detect infrared rays, the smell of carbon dioxide, lactic acid, and sweat. They are able to determine the location of a potential victim from a distance of several tens of meters.

The sound from mosquitoes, according to manufacturers, is of a certain frequency. The human ear cannot detect it, but insects hear well. What frequency it should be, studies were carried out, as a result of which a value of 4 kHz - 6 kHz was revealed.

On a note!

Manufacturers claim that the mosquito-repellent sound imitates the flight of a dragonfly. However, the predator, by flapping its wings, creates ultrasound at a frequency of 20 kHz, which contradicts the information indicated on the device. If mosquitoes heard the approach of a dragonfly so clearly, they would not become victims of a predator and would have time to move to a safe distance.

Does ultrasound against mosquitoes help in the fight against insects? :

Probably everyone has encountered the annoying buzzing of insects and mosquito bites. If you can protect yourself at home with the help of fumigators and plates, then in nature it is more difficult to do this.

Sprays, lotions, and spirals contain chemicals that are undesirable for use in areas where there are children or pregnant women. In principle, they are not so harmless for everyone. Recently, they have begun to actively offer ultrasound against mosquitoes.

How does ultrasound work?

Ultrasound against mosquitoes works quite simply - it releases waves of a certain frequency that humans cannot hear. But insects actively react to them.

Human eardrums have a complex structure, so they do not vibrate as actively as those of mosquitoes, bats, and flies.

The latter catch frequencies using not only their ears, but also their antennae, villi on their paws, and genitals.

Ultrasound for mosquitoes does not kill insects, it only repels them, driving them to a safe distance. This device was known 30 years ago, but began to be actively used only now.

Advertising videos and posters can be found on the Internet. Reviews vary: some claim that there is no better means of protection, while others take the position that ultrasound is absolutely useless. Such devices cost from 1000 to 5000 rubles.

It all depends on what type of device you will purchase.

What does the insect hear?

Many people ask why ultrasound is effective against mosquitoes? What sounds cause insects to fly to a safe distance? To answer this question, you need to know the following facts. Scientists have proven that only female mosquitoes bite people, and this happens immediately after mating with a male and fertilization.

Options are offered for mobile phones, smartphones, and players. You can calmly enjoy your time in nature with mosquito-free music and without putting in much effort.

Is ultrasound dangerous for humans?

Ultrasound in the dose supplied by animal and insect repellers is absolutely safe for humans. The human ear is simply not capable of perceiving or hearing it. We usually hear sound with a frequency ranging from 16 to 20 kHz, but ultrasonic waves are above our threshold of sensitivity. The vibration level of ultrasonic waves is usually almost 70 kHz.

Also, in addition to frequency, sound is measured in decibels. The human body is able to calmly perceive pressure up to 120 dB. While many repellers are rated at 100 dB, so they do not have a dangerous effect on the human body.

Outdoor mosquito repeller

A wide range of outdoor mosquito repellers helps you choose an effective product for any occasion - a country picnic, a multi-day hike, an out-of-town vacation with children, or protection of farm animals from parasites. All instruments, devices, chemical and natural insecticides have their advantages and disadvantages, and once you understand them, it is easy to make the right choice.

Repellents for use on skin and clothing

The most well-known means of personal protection against blood-sucking insects are repellents. They contain chemical toxic substances (insecticides) or natural plant components (for example, essential oils) with a similar mechanism of action - muscle paralysis and death of the mosquito or repelling it due to a persistent odor. Repellents for use on skin or clothing come in the form of sprays, ointments, or gels.

Smoke bombs

A simple and easy-to-use mosquito repellent in nature is a smoke bomb. It is designed for an area with a radius of 300 m to 1 km, contains wax, paraffin and the insecticide permethrin, which destroys insects by contact. The burning time of one stick is 5 minutes, the duration of action in the open air reaches 3 days. Suitable for removing mosquitoes around the perimeter of a summer cottage; after processing, all collected vegetables or berries must be washed before consumption.

Spirals

The spiral-shaped fumigator is ignited on one side, and after 20 minutes its active components contained in the smoke destroy mosquitoes within a radius of 3-4 m, both indoors and outdoors. The duration of protection lasts from 7 to 12 hours.

Ultrasonic repellers

Mosquito repellents, powered by batteries, rechargeable batteries or mains electricity, emit a special sound signal that scares away female insects, protecting humans from their bites.

Every year we buy many products that can protect us from mosquitoes. These are all kinds of creams, ointments, sprays, sockets, spirals, etc. However, all this costs a lot of money. To save a little money, we suggest you make your own mosquito repeller using available materials. Without spending a lot of time.

For the first version of the repeller we will need: – matches; – metal plate; – mosquito repellent plate; – round flat candle; – pliers.

The first option works well at home or outdoors in the complete absence of wind.

We take a metal plate and use pliers to bend it on both sides at an angle of 90°. So that we get some kind of street bench without a back.

Then on one side we fold one edge again. We will get an inclined plane.

After this, we place our curved metal plate on the metal body of a lit candle and place a mosquito repellent plate on top.

For the second version of the repeller we will need:

- a box with a metal lid; - a metal plate; - a ferrite ring: - a mosquito repellent plate; - a round flat candle; - pliers; - matches; - a glue gun: - a bolt and a nut.

The second method can be used outdoors even in windy conditions.

We take a metal plate and make a small hole at one end. Then use pliers to bend it. After this, we make another bend on the same side so that our mosquito repellent plate fits on the remaining part of the plate. Once again we bend the ends of the plate so that it fixes it.

We cut out a round hole in the metal lid in the middle, as well as another small one at the edge.

Now we need to glue the ferrite ring onto the lid, aligning it with the large hole. You can use a narrow piece of any plastic pipe as such a ring.

We glue the metal candle stand inside the body of the box exactly in the middle. We insert the candle, close the lid and check how accurately the candle wick fits into the center of the hole. While the glue is not completely dry, center the candle body.

Then we take our metal plate, insert a bolt into the hole and secure it to the lid with a nut.

After this, light the candle and close the lid. If the candle goes out, make several holes in the lid.

You can make your own ultrasonic mosquito repeller yourself, following the diagram. You need minimal knowledge of physics, a little time and effort.
