With the arrival of spring, many summer residents discover earthen piles on their plots, which are a product of the vital activity of moles. Not only are these creatures capable of ruining all plantings, but the foundation of the house can also suffer from them. If you don’t have the time or desire to hunt these animals with a shovel at the ready, then we recommend using such a miracle of technology as an ultrasonic mole repeller. We present to our readers a rating of popular models of mole repellers that will free your area from uninvited guests.
No. 10 – Help 80410
Price: 600 rubles
One of the most budget-friendly solutions to the problem of moles in your garden. If you notice that your favorite flower bed has become more like a battle arena, then urgently purchase Help 80410, otherwise soon only memories will be left of your favorite plot. The device operates in a fairly wide range of frequencies, which will not allow moles to get used to ultrasound, and its operating area is 800 square meters, which will be enough to cover several standard summer cottages of six acres at once.
The device runs on four R20 batteries, which are not included in the kit, but their resource is long enough and you won’t have to change them every time you visit your estate. Of course, the device is not distinguished by high build quality or the materials used in it; it cannot be called reliable either, but nevertheless this model has gained wide popularity among domestic summer residents due to its affordable price.

The effect of ultrasound on bedbugs
The main argument according to which ultrasound is not effective against bedbugs is that this type of insect does not have organs that produce sound, and therefore they do not have hearing organs. But scientists still have not come to a consensus on whether bedbugs make sounds. After all, not only the fluttering of wings or the friction of legs against legs can serve as a source of sound in insects.
Linen bugs
Bedbugs have sensitive hairs connected to nerve endings on their legs and abdomen. With the help of sensilla, insects sense thermal radiation and air vibrations. No hearing organs have been found in bedbugs, but high sensitivity to odors and temperature allows them to find food and a sexual partner.
Bacteria and viruses also do not have hearing organs, but ultrasound, thanks to the cavitation effect, successfully fights them. It is used to sterilize products, medical instruments, and drinking water. Under the influence of ultrasound, bubbles appear in biological fluids, which increase in size with prolonged exposure to sound. When bubbles burst, they have a shock and thermal effect, destroying the tissues of living organisms. The parasite does not have to listen to ultrasound to feel discomfort from repelling with ultrasonic waves.
The lower the ultrasound frequency, the easier it is to produce cavitation and the more aggressive its effect on living organisms. Therefore, many devices use a frequency of 20-22 kHz. It is impossible to say for sure whether ultrasound helps against bedbugs, since studies have not confirmed the effectiveness of repellers. But the synergistic effects of ultrasound and insecticides have been studied.
The ultrasonic agent creates cavitation in the parasite’s body, which increases its sensitivity to insecticides. Ultrasound against bedbugs together with insecticides are effective even against resistant insects. The combined effect, which has synergistic properties, also occurs when an electromagnetic bedbug repeller is used. It combines the action of ultrasound with magnetic radiation, enhancing each other's effectiveness.
No. 9 – Masterkit Antikrot
Price: 900 rubles
A simple and effective, and most importantly environmentally friendly device that will become your faithful ally in the fight against garden and lawn rodents. For people, pets, as well as useful living creatures such as worms and beetles, the device is absolutely safe. The range of the device is 20 meters, and it is powered by Krona batteries.

No. 8 – Rexant R30
Price: 1000 rubles
This ultrasonic repeller is powered by a solar battery, which makes it one of the most economical options when dealing with earthen pests such as moles, shrews, snakes and other unwanted guests in the garden. Most rodents have poor vision or no vision at all, but their hearing is amazing, and therefore they can hear an ultrasonic signal many meters away and do not dare to poke closer.
The operating radius of the device is quite a decent 30 meters, and the frequency range varies from 400 to 1000 Hz. Externally, the device looks like a rather long plastic nail, which is practically invisible once installed in the ground. If you are not eager to constantly spend money on batteries, but still need to fight moles, the Rexant 30 will be an almost ideal solution.

Reviews
This device completely disappointed me . To kill bedbugs, I purchased several banzai and installed them throughout the apartment. Most of the appliances were concentrated in the bedroom. At first it began to seem to me that bedbugs simply changed their place of residence, running from one place to another. And now a month has passed since using the device, but I still haven’t managed to completely get rid of bedbugs. True, there were fewer bites.
As a result of the constant operation of ultrasonic repellers, a specific sound arose - noise. It resembled the background created by an old tube TV. I couldn’t stand it for a long time, and, in the end, I treated the apartment with Tetrix. It’s a shame that so much money was spent and I never got any results. Expensive drugs have at least some effect, but these scares are just a publicity stunt.

While looking for housing for our daughter, we subsequently discovered bedbugs in it. At first, we did not want to resort to chemistry, so we decided to use the trendy drug “Typhoon”. Despite all our efforts, we did not get the expected effect . My daughter constantly had inflammation on her body from bites. We began to think that bedbug repellers are not so safe for human health. Perhaps manufacturers do not tell consumers everything. I decided not to waste time on trifles and bought three devices for killing bedbugs at once, paying 5,500 rubles for them. Although with this money I could have bought the most expensive insecticide and would have long forgotten about these bloodsuckers.

No matter what anyone says, ultrasound against bedbugs can indeed be very effective. You just need to choose the right repellers - it should be a truly professional device, and not something that is sold on every corner. This is exactly how we solved our problem - my husband brought an ultrasonic repeller from Germany. Already after the first treatment we felt its effect - for the first time the night passed peacefully. We did not notice any unpleasant sensations.
I didn’t want to deal with chemicals because we have children in the house. And these drugs themselves have long been outdated. True, not everyone can afford to purchase a professional ultrasonic repeller due to its high price. That's why people buy regular dichlorvos, hoping that it will help them. After one treatment, within a month there was not a single insect left in the apartment. And we don’t care where they went to visit. The main thing is that they don’t bother us anymore.

No. 7 – Anti-Crote Dadget
Price: 1200 rubles
A compact device with a coverage area of approximately 5 acres. Producing constant vibration, the device will make it undesirable for moles to be on your territory, and you and your pets will not even notice its existence. It is worth noting that, unlike previous models, this device is made of impact-resistant plastic, so you don’t have to be afraid of accidentally damaging it.
In general, there is only one drawback - the range is not very large, which will not be enough for most summer residents, but you can always buy a couple of such repellers and cover a fairly large area.
Antikrot Dadzhet
No. 6 – Sititek Thunder-Plus
Price: 1600 rubles
An interesting device that can boast excellent protection for the case and its contents - corrosion and snow will not matter to the inside of the device. The device works great on moles, mice and rats, so you can forget about chasing small rodents around the area. The phenomenal impact area - up to 1250 square meters - will allow you to use such a device on several nearby garden plots at once, so you can simply chip in with your neighbors in the country and forget about the pest problem once and for all.
The high efficiency of the device also deserves praise - it can operate for up to six months with one set of batteries. In general, this is a model that deserves close attention at a very reasonable price.

Review of popular repellers
There are many ultrasonic repellers on the market now, both professional and semi-professional. To choose the most effective device, you need to study its characteristics. The most popular and advertised are:
- EMR-21 is an ultrasonic bedbug repeller produced in Bulgaria. The device operates from the network. The manufacturer guarantees that when using it, the parasites will disappear from the house after 4 weeks. In case of severe infestation, you need to extend the effect of the ultrasonic repeller for another 4 weeks. The device generates ultrasound and the bedbugs disappear from the house. The price of the device is 1100 rubles.
- Typhoon LS-500 is a domestic product based on the effect of ultrasound on insects. The advantage of an ultrasonic repeller is the presence of an automatic frequency switch, which prevents insects from becoming accustomed to waves of a certain frequency. Price – 1100 rub.
- Ecosniper ls 919 – has a high degree of coverage. One device can operate on an area of 180-200 m2. Also has a frequency switch. The manufacturer (Taiwan) claims that bedbugs leave the apartment within 2-6 weeks. The price of the device is 660 rubles.
- Tornado Impact FP-003 is a new development on the ultrasonic repeller market. In addition to ultrasonic waves, the device generates electromagnetic waves that penetrate the thickness of the walls, spreading through the wiring, expelling bedbugs from sockets, electrical panels, and household electrical appliances. Can be used both on an industrial scale and in apartments. The manufacturer claims that the device does not affect the operation of electrical appliances, mobile phones, or the human body.
- The Pest Redjekt bedbug repeller combines ultrasonic and electromagnetic effects, so manufacturers have special hopes for the device. The coverage area is 200 m2, which allows you to limit yourself to one device for treating the room against bedbugs. The price of the device is 2000 rubles. You can order the device through the online store.

Electronic devices have different effectiveness, which depends not only on the characteristics of the device, but also on the manufacturer.
Like many advertised insect repellents, the cost of which is quite high, ultrasonic repellers have many fakes. Counterfeit is slightly cheaper than the original and is not capable of destroying insects, as it generates waves of insufficient power. When purchasing a repeller, you need to make sure that the device you are purchasing is not a counterfeit.
Many devices are similar in appearance to an adapter, which you just need to plug into a power outlet to start working. The sound volume during operation is minimal, but some reviews contain complaints that the device beeps. In order for the home to be completely protected, you need to choose the right place to install the device, set the volume to ensure complete destruction of insects and maintain the time specified in the instructions for which the ultrasound will be emitted.
You can buy the device in stores in large cities such as Moscow or order it online. Delivery is made to the most remote settlements of the country. The ultrasonic protector has different reviews, which can be found on the forums.
No. 5 – Grad A-500
Price: 2000 rubles
The effect of ultrasonic radiation emanating from this device on the nervous system of rodents leads to the fact that they immediately have to move away to a safe distance of about 100 meters. During operation, the device makes some noise, which may not appeal to every summer resident, but the owners of granaries and retail premises simply adore it - such efficiency cannot be achieved for a comparable amount.
The manufacturer guarantees 100% results, and the happy owners of the device confirm this - reviews of the Grad A-500 are purely positive. If the dominance of moles in the area where your site is located is so great that less powerful devices cannot cope, you should try this particular device.

Classification of devices by type
The most widely used drugs on our market:
- Ultrasound based. The manufacturer promises to supply a high-quality ultrasound device that has a terrifying effect on the parasite. As a result of its exploitation, impossible living conditions are created for these insects. It should be noted that this type appeared a long time ago and is not particularly effective compared to other methods. Many rightly abandoned their production and switched to more modern means.
- Devices based on electromagnetic waves. Their frequency coincides with the frequency of amplitude oscillations of the parasite’s nervous system and destroys its body from the inside. This device is also quite dubious in operation and simply cannot inspire confidence in many more or less literate consumers. To be honest, in terms of efficiency these devices can easily be placed on the same line as ultrasonic devices.
- So-called fumigators (essentially repellents based on an unpleasant odor for insects). When the device is plugged in, the special solution inside begins to smolder and emit an odor harmful to insects. But we must pay tribute to these household products; among them you can find the most effective ones.
It is important to know
It should be noted that not all electromagnetic and ultrasonic devices do not have the desired effect. For example, such powerful devices are used against moles and rats. Their powerful action, unfortunately, can negatively affect a person, in particular, his nervous system. These devices are destructive to all living things that are within their range of action. Such methods are strictly contraindicated for use in residential premises.
No. 4 – Ecosniper LS-997MR
Price: 2000 rubles
Repeller with excellent technical characteristics. Its area of action is an impressive 15 acres, one set of batteries lasts for three months, and only a couple of weeks is enough to completely expel moles from the surrounding area. The device emits ultrasonic waves in a random order - their frequency and duration are always different, which means that moles have no chance of developing tolerance to them.
It is worth noting that this device is easy to use - you don’t have to dig it out to change the battery pack, just remove the battery compartment. The device is not afraid of rain and snow, is not subject to a corrosive effect, and mechanical damage can only be caused by deliberately knocking on it with a shovel. A very powerful and effective device that can eliminate the problem of moles and other pests in a matter of days.
Ecosniper LS-997MR
How to choose the right repeller
When choosing a repeller, you should consider the following factors:
- device power - mains-powered repellers usually consume a lot of electricity. At the same time, the battery charge lasts for a certain period of time;
- room area. Carefully study the technical characteristics of repellers. If you need to protect a large apartment, it is better to purchase one powerful device or several ordinary ones;
- Check with the seller that the device has the appropriate quality certificates. When buying a low-quality device or a fake, you risk simply throwing money away;
- All repellers have different prices - the more expensive the product, the more effective the work.
No. 3 – Sititek Grom-Profi M
Price: 2200 rubles
Another device from the “Thunder” family, which has significantly higher productivity than its younger brother. The device body is made of aluminum, which means that the electronic filling remains protected in all weather conditions. The impact area exceeds 1500 square meters, and the built-in vibration motor increases the performance of the device significantly.
The price of the device is slightly higher than that of most devices of this type, but you need to understand that it is not always possible to discourage a large population of moles in a particular area from visiting your site using low-power devices, so if your entire garden area is pitted with holes, it is better to immediately acquire the most effective weapon.
Sititek Grom-Profi M
No. 2 – Tornado OZV.03
Price: 2600 rubles
Second place in our top list of the best mole repellers goes to the flagship device from the famous Tornado brand. The device works on an area of up to 10 acres, but you can be sure that even a deaf mole will not penetrate this territory. During daylight hours, the device is powered by a solar battery, and at night, 4 “D” batteries come into play, the resource of which will last for many months. To replace them, you don’t have to dig up the device, which is also a definite plus.
It may take from two weeks to a month to completely expel Tornado OZV.03 moles, but the chance of the pests returning after this will be zero. Owners of warehouses with wheat and vegetables like to use such devices, but ordinary summer residents will also like it. If you arrive at the site and again discover that all your useful plantings and flower beds have been dug up by rodents, immediately purchase Tornado equipment and forget about incidents of this kind forever.

Natural bedbug repellents
There is also a whole set of folk remedies that can quite successfully repel bedbugs.
- Wormwood - it is either fresh or dry laid out under beds and mattresses. And to prevent bedbugs from getting in from neighbors - in the corners of the room, ventilation ducts and near the door. You can also prepare a decoction of wormwood and add it to water for washing floors, or spray it on baseboards to expel parasites from there.
- Tansy - used similarly to wormwood.
- Kerosene, denatured alcohol, vinegar are products that can repel not only bedbugs, but also the person himself with their smell. They are considered harmful, dangerous and obsolete.
- Live geranium as a houseplant, and, if possible, a bug bush. These plants repel bedbugs more reliably than expensive fumigators.
But even with these means, you should remember that you won’t be able to kill bedbugs with their help, and even if used correctly, they will only give short-term results. They are more reliable as means of prevention - by constantly using them in the house, you can significantly reduce the chances of parasites entering from neighbors or from the street.
