Ultrasonic insect repeller - quite effective and convenient thing, but only under the condition of proper operation. Such a device can really scare away a considerable percentage of certain insects, and in some cases even rodents (in the house and in the garden plots).
A classic example of the use of ultrasound against insects in the domestic environment is mosquito repellent. The effectiveness of the devices in this case is explained quite simply:
- mosquitoes use ultrasound for communication, which they produce with their wings - with a subtle sound of a certain frequency, they warn their kin about danger.
- Ultrasound is also used by active mosquito hunters - bats: with it, winged predators orient themselves in space and discover prey.It is not surprising that when mosquitoes catch a characteristic squeak, they instinctively try to leave the dangerous place. Accordingly, an ultrasonic insect repeller that imitates such sounds will effectively repel mosquitoes.
As for synanthropic insects (cockroaches, bedbugs, domestic ants, etc.), they do not use ultrasound for communication, which means that the usual low-power (i.e., household) ultrasonic repeller will be ineffective against them, as evidenced by the numerous reviews of disappointed buyers.
Generally speaking, ultrasound of very high power is quite capable of scaring off insect pests - industrial ultrasound repellers of rodents and insects, used mainly in warehouses and open areas, for example, work on this principle. However, ultrasound of such strength is harmful to humans, especially with constant or regular exposure, and therefore, in everyday life, powerful electronic insect repellers are not used - in the bedroom you should definitely not turn them on for the night.
It's amazing to see ads,in which small ultrasonic devices that are slightly larger than a matchbox are positioned almost as a panacea for any unwanted living creatures in the house: from cockroaches, spiders, bedbugs, flies and other insects. And the consumer, tired of the fruitless struggle with annoying pests and parasites, wants to believe that it is enough to plug a neat magic box into the socket, and it will relieve you of problems forever ...

“A year ago, our department received an order to check and test models of ultrasonic insect repellers on the market. I will not call the customer not to be accused of advertising, I can only say that this is a large retail chain that is ready to spend serious money on checking equipment and really effective protection of warehouses.
We bought 17 models of repellents, including those that are sold only abroad with delivery to Russia. The experimental stand looked like this: in the center of the room there was a cage with rats and a tank with insects, at equal distance from which one device turned on and worked for several hours.During this time, laboratory technicians recorded all deviations in the behavior of animals and insects from normal. Our task was to find such a device, which would cause the greatest anxiety of the experimental.
As a result, it turned out that of the 17 models of ultrasonic repellers of rodents and insects, at least somehow the behavior of cockroaches, meal stalks and rats was affected by only three devices that are not used for domestic purposes. Two of these devices are not sold in Russia, one - Russian-made. All these tools can not be included in the bedrooms and in places of recreation of people. And besides, there is a 100% guarantee that insects and rats will try to leave the scene of the sound, no, because hunger is not an aunt, but they can endure discomfort. ”

All variety of electronic scarers
Despite the general principle of operation, all ultrasound insect repellents and rodents can be divided into several groups, depending on their capacity, scope and design features.
So, one of the most powerful electric scarers are designed to scare away birds and rodents in gardens (including not only mice and rats, but also moles).Such devices include, for example, a professional ultrasonic repeller for the street Bird-X TX-Pro, an LS-2001 device, a KG321 repeller, an Electronic Cat, and some others. It is impossible to use them in the premises where people are located, however, unfortunately, not everyone pays attention to this. (see review below).
Feedback
“We want to thank the manufacturer for the Electronic Cat tool. Although we do not know how effective this repeller is against rodents, this device protects against mosquitoes perfectly. We did not see a single insect in the house this summer, despite the fact that we constantly kept the windows open and did not hang mosquito nets. Since we do not hear this ultrasound, we left the device working in the bedroom for the whole night and nothing prevented us. ”

For use in workshops, garages, in warehouses and granaries produced a whole line of industrial electronic means from insects and rodents. These include, for example, XL-200, UZU-03, Typhoon, etc.
A very large group of ultrasonic devices are mosquito repellents for apartments. The range of such devices in conventional and online stores is quite wide, although the effectiveness of scarers and their appearance are about the same.
As a rule, these are small devices with a plug for insertion into the outlet, producing an ultrasound inaudible by the human ear. Against insects such as cockroaches and bedbugs, as practice shows, they are of little use, despite the assurances of the sellers. As repellers of mice, rats and other rodents, they are also not suitable due to insufficient power.
An example of this group of funds can serve as Riddex, AR140, SmartSensor, Ekosniper, Zenet and many others.

“We bought a Riddex insect repeller in the hope that it would help rid us of cockroaches. As a result, after two weeks of continuous work in the kitchen, there was no noticeable effect on him. There were no fewer cockroaches; at night they crawled as boldly under his squeak as they did without him. Already in the autumn they bought an electrofumigator from insects in the apartment and only after it was working, the cockroaches began to die. Conclusion: these pests need to be destroyed, not scared away. ”

And, finally, for even greater convenience of consumers, small ultrasonic repellers are produced in the form of key chains, watches or bracelets that are worn on the wrist or cling to a belt, and when turned on, mosquitoes are repelled from a person on the street.It is worth noting that fishing or in the taiga, they are unlikely to scare away thousands of mosquitoes or gnats.
Feedback
“I decided in the middle of summer to buy an ultrasonic insect repeller for fishing trips, because mosquitoes gnaw very hard, and walking constantly in clothes and a mask from bees is uncomfortable. I ordered two key chains via the Internet, which need to be hung on the belt. At first they experienced them simply in the country, they worked well. But on the river they failed. Mosquitoes here are painfully evil, they don’t pay any attention to these scarecrows. On priborchik there are two modes of operation, one more powerful. So, on mosquitoes on the river, no one acts. Therefore, it is possible to buy such an insect repeller only for the house, and for fishing it is better to take a can with DETA. ”

Universal insect and rodent repeller
Separate conversation deserve ultrasonic repellents, positioned "from everything and everything": from all rodents and insects. Entrepreneurial sellers do not spare any funds for advertising such devices, but in practice - after the acquisition and “tests” - it turns out that the scarecrows do not cope with their task, and the money was simply thrown to the wind.

“We bought the Pest Redzhekt repeller of mice and insects in order to get rid of rats in the basement. I fear them terribly, and my husband was on the voyage. The device does not work. More precisely, it works, but there is no sense from it. Rats both lived and live, despite the fact that the device operates around the clock. When my husband came back, I just took the rat trap and in a week we caught 4 rats. After that, I had to do repairs, plug holes and restore order, but now it’s clean in the basement. ”

When choosing an ultrasonic electric repeller for mice and insects, it should be remembered that the more powerful the device, the more dangerous it can be for humans. Powerful professional repellers of the LS-2001 type cannot be used in residential areas due to the negative impact on the human psyche and nervous system.
If ultrasonic electronic repellers of rodents and insects are positioned as household and at the same time supposedly completely safe for home use, then this is suggestive: either the seller is silent about the harmful effects of ultrasound (if the device is powerful) or the device is not really effective. Judging by consumer feedback, such devices are often not capable scare not only cockroaches, but even mosquitoes, not to mention the more "serious" pests - rodents.
An example of this is Riddex, a widely advertised ultrasonic rodent and insect repeller - a device that actually doesn’t really help from mice and rats.
If you still decide to buy a powerful ultrasonic repeller (for example, for use in some non-residential premises or outdoors in a garden), then remember that such a device will be quite expensive, and you need to look for it in large reliable stores. If the device is suspiciously cheap, then the sound it makes to scare away insects is unlikely to be frightening to rodents.
Trinket repeller against mosquitoes
Ultrasonic insect repellers in the form of a keychain are produced in the majority in China, and their cost on the market is about 150 rubles. To repel insects, the keychain starts immediately after switching on.
Such miniature ultrasonic repeller works in two modes:
- the first is a squeak imitating the sound of danger made by mosquitoes;
- the second is a soft crack, similar to the sounds made by bats (it is this mode that is considered the most effective).
The undoubted advantages of the ultrasonic keychain are that, firstly, it is very compact, and secondly, it can work continuously from a regular battery for about a week.
Feedback
“I bought for the sake of interest such an ultrasonic key chain and a bracelet on my hand. The effect of them is incomprehensible. The house doesn’t seem to touch the mosquitoes, although if I go out into the street, they immediately begin to bite. The electronic repeller-bracelet died out in two weeks, and then the keychain worked the same - I turned it on after lunch and in the morning. ”

Repeller Riddex and reviews about it
Riddex is one of the most widely advertised today ultrasonic insect and rodent repellents. It is a compact device that is plugged in and allows you to scare mosquitoes from a room of up to 200 m².
Sellers claim that the device is equally effective against any insects and rodents, however, having experienced a repeller in action, for some reason, many buyers are convinced of the opposite.
Feedback
“They ordered Riddex for 430 rubles, zero effect, cockroaches just crawl on it. In the end, they had to be removed with Dichlorvos and poisoned gel. ”

KG321: universal soldier?
KG321 - one of the semi-professional ultrasonic repeller, focused on the use in warehouses, industrial premises and basements. This device can really be called universal in terms of use, since the device allows you to adjust the frequency of ultrasound and its power. Thanks to this function, the repeller can be used both in the house - for controlling mosquitoes, and in warehouses - for removing pests of grain and groceries.
The price of this ultrasonic repeller is about 2500 rubles.
Bird-X Transonic Pro: Industrial Scare
The repeller Bird-X Transonic Pro is designed to scare away birds, insects and rodents in gardens, in vegetable gardens and in open grain stores. This ultrasonic device operates in five modes, each of which is focused on various pests. As mentioned above, it can not be used inside the premises, as well as where it produces ultrasound for a long time directly affect the person.
The price of the device Bird-X Transonic Pro is about 8,000 rubles.
Starting to use any ultrasonic insect repeller, you must, first of all, carefully study the rules of its operation. Some appliances, for example, should not be turned on while people are present.Other devices must work strictly on the streets, and only a few scarers do not have such restrictions in use.
Remember: ultrasound, even if we do not hear it, still affects our body, and, depending on the power and duration of exposure, can cause headaches and nervous disorders.
It is for this reason that it is not recommended to assemble ultrasonic insect repellents with your own hands. Without special knowledge and experiments, it is difficult to guess the sound of which frequency and power will remain safe for humans. Considering the variety of offers on the market (and not only in the domestic), it is much easier to buy a ready-made device from a reliable company and use it for your pleasure.

We have a domestic scarer in the house. I suspected that you can not install a powerful device in residential areas, so I scare away mice and rats or in the attic, or in the garage. Sometimes I just install it on a garden plot, the benefit is that the device can also work from a battery or batteries.
I purchased a Riddex repeller for 1450.2 months passed, cockroaches only increased. Tuff.
Cockroaches appeared in my apartment, I wanted to buy ...
Complete nonsense. I bought this miracle device called RIDDEX. He worked for 10 days, the mice both ran and ran, but this is not the worst thing. Fortunately, I didn’t sleep and was near the house, I heard cotton, as if by firecrackers, I went to see what happened, and about a miracle - the whole house is in smoke, and this miracle burns in the socket, the appliances and furniture have suffered. So if you value your life and your property, do not buy this nonsense.
After all, I initially understood that there could be no panacea for several representatives of the animal world. I protect my crop with the help of a rather powerful ultrasonic rodent repeller. It is good that at least there are no mice in the apartment.
It did not work on insects and animals and will not work. There is such a science, called physiology. So that. Kind people! On lice incompetence such babosiki are made that you never dreamed of! No offense.
Bought two. The key ring is normal, hung up on the keys and forgotten, the second one hangs on the wheelchair, so as not to forget to attach it, it drives away mosquitoes and midges, costs 83 rubles.
I'm afraid to install such devices in the apartment, but for the garden I took the sititek ultrasonic repeller. It is installed far enough away from home, so I hope there is no negative impact on people. But the birds fly around the garden side, not one pecked berries for the season.
Bought Riddex, lit in three colors: blue, yellow and red flashing. Sense zero, but the children like it - use it as a nightlight. Before you buy something, look for reviews about the device on the Internet.
R.S. Mosquitoes both fly and fly.
People, do not buy the device Leomaks for protection against any insects - this is such a bullshit, flies and mosquitoes are sitting on the device and they spit on some waves there! And in general, their products - rubbish.
