The principle of operation of a mosquito repeller. How does ultrasound affect mosquitoes? Which models are more effective: stationary or portable? Is it possible to replace an ultrasonic repeller with an electric fumigator? Is ultrasound dangerous for humans and pets?
Mosquitoes are quite annoying insects that can anger even the calmest person. This is explained not only by bites, but also by annoying squeaks; in addition, this class of insects can carry different types of infectious diseases. Because of this, owners of houses and apartments try to get rid of mosquitoes, especially at night, since they do not allow you to sleep peacefully (their peak activity is at night).
Advances in radio-electronic production have made it possible to develop special devices, among which the ultrasonic mosquito repeller is particularly effective.
How the device works
An ultrasonic repeller is an electronic device whose operating principle is the generation of sound waves that are in the ultrasonic range. A person does not perceive such a sound, but mosquitoes and other insects cannot tolerate them. It is worth noting that it is the females who respond to the device (males do not bite), the “squeak” of the repeller irritates them and they fly away from the problem area to a long distance.
Note that the human ear does not perceive such ultrasound, which eliminates the risk of harming the body.
Nowadays several types of devices of this type are produced, with the help of which you can protect yourself from the invasion and attack of mosquitoes.
For example, the most popular options are:
- Stationary models - operation is carried out from a 220 V network. The repeller is intended for use inside a living space. It can also be used in other buildings, but only if electricity is available. Such a device guarantees protection against insects within a radius of 20 meters.
- Portable models. This product option requires batteries or an accumulator. They are distinguished by their small compact sizes, so they are suitable for use on vacation in the forest, near a river or pond. The range of the device is about 2.5 meters.
If we talk about the advantages of such repellers, we can note the following:
- The possibility of danger to people and pets is excluded,
- There is no risk of negatively affecting the operation of other types of electronic products in the room,
- Small size and weight, which makes them easy to transport if desired,
- Minimum electrical energy consumption,
- The portable model can run on 1 battery for the entire season.
According to consumer reviews, ultrasonic mosquito repellers are quite effective and effectively fight pests both indoors and outdoors.
Below we will look at the features of the most popular models, find out the advantages and disadvantages so that you can choose the best option based on your requirements and wishes.
Advantages and disadvantages
Ultrasonic mosquito repellers have the following advantages:
- ease of use;
- safety for people and pets;
- no impact on household appliances;
- long operating time;
- low electricity consumption.
However, the following disadvantages should be noted:
- high price;
- the likelihood of buying a low-quality device;
- After the repeller is turned off, the insects return.
Interesting! Despite the popularity of repellers, scientists annually conduct a lot of research that has not yet proven the 100% effectiveness of these devices.
Typhoon LS-200
Typhoon LS-200 is designed for stationary use; during operation, ultrasonic frequency waves are generated in the range of 418 kHz. It performs well in the fight against different types of mosquitoes. The action begins immediately after the device is connected to the electrical network. You can independently set the required level of radiation power. Suitable for protecting premises whose area is within 1540 square meters. The cost of the presented model is about 1100 rubles.
Advanced devices
The most modern and technologically advanced insect repellent device is a device that has built-in computer control. Therefore, if the question arises about which ultrasonic mosquito repeller is better, there will be one answer - a device with computer filling. After all, it has not only ultrasonic radiation, but also electronic, network, electromagnetic and infrared. The combination of all these radiations greatly increases its effectiveness in repelling a wide variety of insects. The radius of influence of the device is 200-300 square meters. It is mounted on any plane using a bracket that allows you to rotate the device in any direction.
All of these types of devices are powered in a variety of ways, from simple batteries to solar cells and AC adapters. There are models on sale that can operate on all power sources.
Tornado OK. 01
A compact device that operates on batteries or mains power. Thanks to these features, the ability to choose a power source, Tornado OK. 01 can be used both indoors and outdoors. It is worth noting that the repeller has no negative effect on the human body or animals. The price of the device ranges from 1.5 thousand rubles.
Do not forget that devices of this type exhibit the maximum level of efficiency only when there are no objects inside the room or on the site that absorb ultrasound waves.
Comparison of parameters of different models
Model Typhoon LS-200
Some of the popular versions are: Tornado OK.01 and Typhoon LS-200. In terms of cost, both options differ slightly: the first is offered at a price of 1,500 rubles, the second – 1,100 rubles. The Typhoon LS-200 device is somewhat less functional, since it operates on an area of 40 square meters. m, and the ultrasound frequency ranges from 4-18 kHz.
The power source of this design is mains voltage. But the Tornado OK.01 model operates on an area of up to 50 square meters. m, the frequency range is much wider: from 4 to 40 kHz. This model is powered by three batteries.
A much more affordable option is the Cosmos Economy ultrasonic compact mosquito repeller, which is offered for only 160-500 rubles. (depending on the store). Its range is small - no more than 5 m, the power source is a battery. This device emits sound vibrations identical to those produced by dragonflies, which are known to be warring insect species. Another affordable device is the Mosquito Keychain Repeller. Its price is only 900 rubles, and its coverage area is 2 square meters. m. This device is made in the form of a key fob, and accordingly, it is powered by a battery.
User opinions on different versions
Model Cosmos Economic
The lowest rating belongs to the Cosmos Economy device. None of those who had the opportunity to evaluate it in action were satisfied with the results. Although its cost is extremely low, which is very attractive, however, these costs in almost all cases turned out to be impractical.
But, if you really need to purchase an effective ultrasonic mosquito repeller, which device is better today?
It will be difficult to answer this question unequivocally for the same reason that the range of oscillations of ultrasound frequencies emitted by different types of such insects differs. But there are often positive reviews about Tornado brand devices.
Do-it-yourself repeller
If you plan to purchase an expensive model of such a device, you can easily try to assemble it yourself. It will probably cost significantly less. But to create a truly effective design, you will need some experience in such work. A do-it-yourself ultrasonic mosquito repeller can easily be assembled using one of the many schemes offered by the most advanced users in this field. Here is one of them, created in the Splan 4.0 program:
For work, simple, non-scarce elements are used, which can always be found in the right quantity. Particular attention should be paid to the piezo emitter, since it is advisable to purchase an option that creates increased sound pressure during operation. This could be ZP-22. For those who have the opportunity to make a printed circuit board, the following option is offered:
To implement this solution, you will need a ferric chloride solution, with which you will need to etch the tracks on the board, after which they are covered with a protective gel flux. To complete the picture, it is necessary to select a battery of sufficient voltage for comfortable operation of the device for some time.
Watch the video, do it yourself: When assembling an ultrasonic compact mosquito repeller with your own hands, the most important thing in implementing this task is to create a sufficient level of sound vibration frequency. To adjust this parameter, you should select frequency-setting capacitors C1 and C2 (see diagram). With a fairly large capacity of these elements, the output frequency is within the range of not ultrasonic, but simply sound vibrations.
To change the situation, you should reduce the capacitance of the capacitors, which will even allow you to achieve a frequency level within 60 kHz. But these are too high numbers to repel mosquitoes, so it is recommended to set the frequency within 24 kHz.
Thus, to obtain an effective ultrasound device, you can use your own resources and knowledge, saving a certain amount of money. If you succumb to temptation and purchase the most affordable version of the device in the store, then there is a high risk of not getting any return from it, as practice and user experience have shown.
Weitech WK 0029
Weitech WK 0029 device made in Belgium. Its main difference is its compact size and low weight. Intended for repelling both indoors and outdoors; in addition, it can be used in cars. Provides protection for a space whose area is no more than 50 square meters. During operation, it is not accompanied by the release of foreign aroma or noise. Almost a safe option for people and pets. The cost is about two thousand rubles.
Elimination by mechanical means
. The smallest category that includes devices that do not use ultrasonic repellent technology. Sticky tapes, electric shock rackets, and imitations of wasp nests are used relatively rarely, since their effectiveness is lower than that of ultrasonic devices.

What is better: scare away or destroy?
Many people still argue with each other about whether to eliminate insects or simply repel them. There is no clear answer on this matter; everyone defends their own point of view. But recently, with the development of technology, supporters of peaceful coexistence with mosquitoes have acquired a very tangible argument.
Nowadays, on the market of small household goods you can find an ultrasonic mosquito repeller. Reviews about it show that such a device is an effective device against insects. It has no damaging effect. Therefore, let's list all the advantages of scaring away, rather than killing, uninvited guests:
— Mosquitoes are part of the food chain and serve as food for birds.
— A killed mosquito, which has managed to taste the taste of human blood, is a signal for comrades lurking nearby.
— Mosquitoes cannot be destroyed one by one, but it is quite easy to scare off a flock.
EcoSniper PGS-006B

Expert advice
When buying a device, you should remember that:
1. The best choice is to purchase a multifunctional ultrasonic mosquito repeller. Feedback from people who have used such devices for a long time suggests that such devices can emit many different frequencies that repel different types of insects, and not just one species.
2. Not all such devices can be installed outdoors. Each of them has its own temperature range. For use in an aggressive environment, you should purchase a device that has a waterproof housing.
3. You should buy only time-tested models.
4. A high-quality and effective device will not be cheap.
An ultrasonic mosquito repeller costs on average 850-900 rubles.
The price depends on the design of the model, the set of certain functions and the region of residence of the buyer. There are devices that cost from several thousand to tens of thousands of rubles, but they can only be purchased to order.
Protector Freetime
One of the best models, which is designed to repel annoying insects. The device was developed as a bracelet, the basis of which is anti-allergenic rubber, which eliminates the possibility of releasing toxic aromas; there is also no generation of ultrasound that would be perceived by the human ear, which is important for ensuring a comfortable rest. It is worth noting that the bracelet is safe even for children. Great for tourists and summer residents.
Despite the low power level, it is enough to protect a person within a radius of 1.5 meters. The design is made so that it can be attached to arms, legs, or a belt. It produces a wide range of waves.
It is also worth noting the following features of Protektor Freetime:

No. 9 – LS-915
Price: 700 rubles
A number of repellers can boast of good effectiveness, but there is a nuance - in their work they use chemicals, poisons and other substances that are not very beneficial to human health. The undoubted advantage of ultrasonic devices is their environmental friendliness; they produce sounds characteristic of the flight of a male mosquito, thereby driving away blood-sucking evil spirits. The range of the device is 20 meters, which allows it to cover most apartments.
The device runs on two AA batteries. The LS-915 is perhaps one of the most inexpensive offerings on the market, which could not have a positive effect on its reliability and quality - the device is made of mediocre materials and cannot boast of a long service life. If you are on a very limited budget, the choice is not bad, but if you have the opportunity to spend a little more, it is better to find something else.
LS-915
WR30M
WR30M looks like an ordinary wristwatch with mosquito repellent functionality. The body is made of waterproof material, so it will be an excellent assistant for fisherman, mushroom pickers, hunters, tourists and ordinary summer residents. The device does not pose a danger to humans, since it does not emit harmful components. Affects an area with a radius of 5 meters.

Purchasing is possible on the Internet or at specialized retail outlets; the device will cost you around 1.5 thousand rubles.
Types of devices
All the devices described have the same principle of operation, but there are a great many models and types, and there are more and more of them every year. The basic devices are the following:
— Ultrasonic portable mosquito repeller for autonomous use. It can be attached to clothing or a bag. Looks like a keychain. Many also attach them to pet belts and collars. This also protects animals from mosquito bites.
— Sports ultrasonic models for lovers of an active lifestyle. Such devices are equipped with solar panels, special clasps and a compass. Outwardly, they look like ordinary wristwatches. Not only the service life, but also the charging speed depends on the build quality and battery power.
— One of the effective devices is considered to be an ultrasonic mosquito repeller for the street. User reviews highlight its good performance due to its more powerful sound generator and special features such as a photo sensor. It automatically turns on the device when at least one mosquito appears within its range of action.
Such devices are mounted on the walls of houses. Modern models of this type have purifiers - air ionizers that kill bacteria using insecticide plates.
Ximeite MT-606E
A small device capable of protecting people in the fresh air from bloodsuckers. It is distinguished by the generation of pulses of one frequency of ultrasonic waves. It eliminates the negative impact on humans, while effectively performing its functionality. There are models in the line that allow you to adjust the frequency, so the product is considered universal.
The presented repeller protects an area of 30 square meters. The switch makes it possible to receive both ultrasound and the buzzing of flying dragonflies. Similar models will cost approximately 800 rubles.
Installation and Maintenance
You can install the gas exterminator yourself, following the instructions in the instructions. The location for installation is chosen near the concentration of the largest number of bloodsuckers (decorative pond, river, thickets of tall grass, etc.). In this case, the device must be located no closer than 10 meters from where people are. When the exterminator is operating, you need to take into account the direction of the wind so that the active substances are carried by the wind to the mosquitoes, and not to you. The device should be in the shade because mosquitoes avoid sunlight.
Go to website
Once every 15-20 days you need to change the cylinder (the capacity of the cylinder with carbon dioxide is 10 liters). Propane tanks need to be changed once every 3 weeks. The mesh is cleaned when it is half full.
Some models are equipped with a special protective rain cover.
Mosquito and horsefly repeller "Help"
The model was developed to work in stationary conditions and has an increased power level. The principle of the repeller is the generation of sounds from the male, which attracts the female to the mating process. Fertilized females, trying to ignore such sounds, leave the area that is uncomfortable for them.
If we talk about the distinctive features of this product, it is worth noting:
- Help does not pose a danger to humans, children and pets, since there is no release of harmful substances, it is effective for use both indoors and outdoors,
- No additional configuration required,
- Modernity and attractive appearance,
- Does not affect the operation of household products.
The presented device will cost you 750 rubles, and its efficiency will not be inferior to expensive devices.
Should we trust new technologies?
What do commercials and brochures from manufacturers say about ultrasonic repellers?
The operating principle of modern devices is very simple. The device generates a weak ultrasonic signal that imitates the natural sounds of male mosquitoes. Females (it is they who drink blood) during the breeding and feeding period cannot tolerate such a noise attack and try to immediately move away from the source of “danger”. That is, as soon as you turn on the device, the parasites begin to feel discomfort and fly away.
The problem is that many devices have an ultrasound frequency that is too low to harm mosquitoes. But “louder” devices bring discomfort into a person’s life. Advantages of using the device:
- They are absolutely safe for humans and animals - the waves do not in any way affect the activity of the brain and internal organs.
The only drawback is that if you use a device with the same ultrasound frequency for a long time, mosquitoes may simply adapt to uncomfortable conditions. It is sometimes necessary to change the intensity of the generated signal by switching the existing toggle switch on the device.
Scat
The Skat device is designed to repel mosquitoes and other types of blood-sucking insects inside a residential building, office, hospital, warehouse, etc. Allows you to protect an area whose area is no more than 30 square meters. Works in stationary conditions in the presence of electricity.
There is a switch for three operating modes, making it possible to select vibrations for specific conditions of use. After the device is connected to the electrical network, the effect on pests begins. After a few days you can forget about the invasion of annoying mosquitoes.
The cost is quite affordable and amounts to no more than 400 rubles.
Operating principle
A gas fumigator acts like an electrical appliance. Begins to act after heating the plate. An insecticide is released into the air, which causes muscle paralysis in mosquitoes and acts as a repellent. The radius of influence of the fumigator is 5 square meters. Although manufacturers claim 20 sq. m.
The cylinder reserves are enough for 12 hours of continuous use. You can turn off the burner for a while and restart the device after a while. The plate is enough for one evening.
Folk repellents
It has long been noted and proven that mosquitoes cannot tolerate certain plant aromas. They do not like the aroma of citrus fruits - orange, tangerine, lemon. In addition, they are afraid of anise, eucalyptus, cedar, cloves, juniper and essential oils obtained from these plants. But do not forget that traditional methods require preliminary testing of the residents of the premises for tolerance to aromas.
Among the repellent vegetation you can also highlight geranium, lavender, mint, fir - in this case you will need to dry them. The smell of incense will also be effective; they need to fumigate the room before going to bed - but do not get carried away, since excess smoke can harm the body.
If you own a dacha or country house, then to significantly reduce the number of mosquitoes on your property, you can plant elderberry bushes - the aroma of such a plant irritates insects. In addition, planting tomatoes, valerian, spicy basil, bird cherry, and walnuts have a good effect. Planting the presented vegetation receives double benefits - a harvest and a reduction in the number of annoying mosquitoes.
Are mosquito fumigators effective?
The principle of operation of electric fumigators is the heating of liquid or plates by electric current, which subsequently releases volatile substances that are dangerous to mosquitoes. The fumigator is considered one of the most common and popular products that are used to repel and destroy insects. They are divided into several types depending on the principle of operation - they are pyrotechnic (smoking), evaporating and in the form of sprays.
Let's look at the features of each type:
- Pyrotechnic - during combustion, smoke is released, which repels pests. Among the advantages of this option is the absence of the need for electricity, so they can be used in any place - near a country house, tent and nature. It should be noted that the presence of wind reduces the effectiveness of such a fumigator. It should also be understood that the substance released is toxic to humans.
- Evaporating - used in the electric type of repeller, which operates on a 220 V network. They are presented in the form of plates that are impregnated with pyrethroid or pyrethrin, the action of which is carried out when the heating element operates. After 10 minutes, the connected device begins to evaporate the active substances, and achieving a sufficient level of concentration of the drug indoors eliminates the possibility of new mosquitoes flying in. One plate is valid for eight hours, then it needs to be replaced. During operation, the fumigator does not emit aromas, but despite this, a ventilated room is required. The fumigator must not be placed at a distance of less than one meter from people and pets. It is not recommended to turn on the device in a room where a pregnant woman, nursing mother or child lives. The evaporated substance may cause an allergic reaction in humans. If any of the residents of the house or apartment develops nausea or dizziness, it is necessary to immediately turn off the device, as well as ventilate the room.
- Sprays contain the same substances as the previous type. One can is designed for a month of regular use.
The modern type of repellents is harmless to the body, since repelling occurs due to the release of odors that are unpleasant specifically for insects. But when choosing them, carefully read the ingredients and contraindications.
Summary of the review
An ultrasonic mosquito repeller is a good purchase, not only when we go to the countryside or into nature. This device is a good savior from various kinds of insects in the warm season.
All sorts of creams and ointments, along with folk recipes and special clothing, as well as fumigators and plates, are of course useful tools for fighting mosquitoes, but some of them are ineffective, while others are harmful to human health. Therefore, an ultrasonic device is a successful and harmless acquisition.
However, you should try hard to find a truly high-quality and effective ultrasonic mosquito repeller. Feedback from people often tells us that such devices on the market often turn out to be fakes, which, apart from their appearance, have nothing in common with the real device. The effectiveness of such cheap devices is zero. This is simply extracting money from gullible buyers who have seen enough television advertising. But there is no smoke without fire, which means that such devices exist and work for the benefit of people and pets.
Therefore, many experts advise purchasing the device not at kiosks or flea markets, but in specialized stores dedicated to fishing and hunting. It would be a good idea to read reviews and opinions of people about a particular model of the device. The most popular devices among users are Remilling, Weitech WK0029, Skat-41.
