Moles are one of the major threats among subterranean rodent pests to horticultural activities. Rodents are mainly controlled by mechanical and chemical methods. But recently, electronic devices have appeared that make it possible to fight rodents using more humane methods, driving away moles and other rodents from garden plots with emitted alarming sounds.
There are many types of electronic devices on sale, but they are expensive and do not always live up to expectations. You can verify the effectiveness of a purchased electronic device for repelling moles only after its trial operation.
The proposed version of the electronic device for repelling moles is assembled according to the original electrical circuit, tested in operation for two years and showed high operating efficiency. In the circuit, unlike industrial designs, the possibility of changing the frequency of the emitted signal is easily realized, which prevents moles from becoming accustomed to the emitted sound.
How to get rid of moles in your summer cottage forever?
Although the mole brings many benefits in nature, in summer cottages it is a real scourge. Which is not so easy to remove from your garden. It is necessary and possible to fight the mole! If you don’t fight, you will be deprived of some of the potatoes, for example, one mole is preparing supplies for the winter that reach up to 40 kg of potatoes, and how he loves carrots and red beets. Yes, this is almost my entire harvest!
He also loves to feast on worms, which do a lot of good for us, loosen the earth and saturate it with oxygen. Plus, most of your root vegetables will be destroyed, as they will probably be in the path of the mole.
I know a lot of ways to fight moles, some of them I used myself, some of them were used by my neighbors. Really working and really funny!
Personally, my method is simple prevention in quotes. I always plant onions and garlic around the entire perimeter of the garden. This not only saves you from moles. And also some plants, for example daffodils, which are both beautiful and safe.
And so, ordinary rattles in the form of tin cans on strings have always been disliked by moles. They cannot stand loud noise.
But I got rid of my uninvited guests with the help of a pungent smell, with the help of herring))
I bought a kilogram of salted herring, took it outside and gave it time to sit so that it would give off a “good” smell, or rather, become rotten. And then she tore up the mounds of moles and threw them into the trench, piece by piece, no more than 5 cm long. From such a stench, I would have run away myself.
I threw it into almost all the holes, and repeated the same the next day when the mole began to leave. On the third day he was already outside my dacha plot, may my neighbor Ivan Ilyich forgive me))
I know that electronic mole repellers have now appeared. But they should be chosen more carefully; many do not bring any benefit. It's better to read reviews about them and then buy.
There was also a funny case of fighting a mole in my life. A whole family of moles settled with a relative; the area looked as if it had been after an air raid. Nothing took the moles. And since they feed on insects and some root vegetables, it is difficult to feed them pesticides. The relative became so desperate that no method worked that he borrowed a vibrating plate from a friend. But moles are afraid of sharp sounds, but here it’s just an earthquake)) Starting at lunch, from the beginning and gradually moving in the direction of the mole holes, by the evening he collected half a bucket of mole brood. He says the moles almost jumped out of the holes. This is a physically possibly difficult way, but effective! Sincerely, Grandma Manya...
How to scare away moles in the garden
Moles feed on earthworms, larvae, frogs, mice and insect pupae. They do not touch the roots of vegetables, as is commonly believed. But they cause considerable harm to the garden.
On the one hand, moles are useful in that they destroy harmful insects, especially such dangerous pests as the larvae of the cockchafer. They also loosen the soil well, making it more fertile.
But, on the other hand, they cause even more harm than good. They eat earthworms, which are essential to our earth.
You can get rid of moles using a mole trap or using noise. Place a few noisy turntables on your site and the moles will leave your garden, but not far.
Another way will help get rid of moles. Install a 1.5 meter long pipe into the ground. Place a plastic bottle on its end. Moles will not tolerate the noise that the bottle neck makes in the wind.

How to get rid of moles in the garden
One of the most unpleasant pests in the garden are moles, because of them we lose almost the entire harvest. So how can you get rid of these troublemakers in your garden? There are many ways, including repellers. But in this article we will tell you how you can make a repeller with your own hands.
You need to take a simple, not very long stick, a meter or one and a half long, put your favorite homemade plastic bottles on it, make cutouts as in the photo, and after that stick the windmill into the ground.
The noise that the windmill makes scares the moles and they leave the garden to join the neighbors.
It is important to place them correctly in the right places. This method is most popular among gardening enthusiasts.

We provide wholesale and retail supplies of ultrasonic repellers for rats, mice, moles, and harmful insects, including mole crickets, mosquitoes, flies, horseflies, and cockroaches. Special models for enterprises and organizations, farms, hangars, gardens and fields, water bodies. We have wild and stray animal repellers, bioacoustic, visual, laser, sound, bird repellers, and models with motion sensors. Thermo-mechanical means (fog generators) for processing greenhouses, warehouses, fields, livestock farms. Delivery to any region of Russia. Wholesale deliveries to CIS countries are possible.
Important note when choosing a repeller! People buy one thing to try, put it in storage, and then say it doesn’t work. This shouldn't work
The rat walks around him, inquires and goes to sleep in that part of the warehouse where he cannot be heard. Conducting experiments and putting a rat in a cage next to the repeller (for testing), as one of our customers did, is also useless. She won't jump on walls or stop feeding. Therefore, there is no need to come to us and say that the repeller you tested does not work.
The correct way to install repellers is to fill the entire room with sound. Tornado 400, for example, is designed for an area of 400 sq.m. But this is an area of free space, without shelving, etc. And even in free space, one Tornado is 400 by 400 sq.m. , this is not enough. It is better to install two or three Tornado 400 from different sides, and preferably under the ceiling to cover the entire area. If there are additional rooms, then separate devices must be installed in them.
Putting 4 pieces of Tornado 400 in a bathhouse, as another of our customers did, is another extreme, and it is not necessary, although it is effective. According to him, the next morning there were dead mice lying there. But we want them to just leave and not die. By the way, they still need to go somewhere, so leave them this opportunity.
Therefore, a big request to our customers. Of course, we will sell you one repeller “to try,” we won’t go anywhere, but don’t come to us with complaints later. And if you leave a negative comment, then please write: “I followed the recommendations for installing repellers outlined here.”
general information
A large number of moles appear in gardens in the first half of summer. This occurs due to the fact that the upper soil layer of forests and meadows becomes scarce and depleted. And garden associations and summer cottages with their fed “fat” soil, teeming with all kinds of living creatures, attract moles like a magnet.
During a short hunt for its food, a mole can dig up the entire area up and down, while spoiling a vegetable garden, beds with crops or a beautiful lawn. To prevent this from happening, you need to know how to get rid of an uninvited guest. If you do everything consistently, the result will be definitely positive and the mole will leave the area where he is not welcome.
Mole
There is an opinion that moles are afraid of unpleasant odors. As a result, some summer residents water their gardens with carbide and kerosene, scatter rotten fish around the area and use smoke bombs. However, such methods are unlikely to suit good gardeners - is it possible to have a good rest in a plot that constantly stinks of rotten meat and kerosene?! Therefore, people are looking for alternative ways to fight.
Attention! Industrial enterprises have developed and produce various types of electronic repellers. But their price is quite high
Experienced summer residents know that moles cannot stand any kind of noise. They do not like the sound of metal, the crack of plastic, or the ticking of an alarm clock. It was these characteristics of the animal’s character that served as the theoretical basis for the creation of various types of mole repellers.
Alarm clocks
It is very easy to make a mole repeller from ordinary cheap battery-powered alarm clocks. Alarm clocks are set at different times to ring and the clocks are placed in jars with screw-on lids. The lids are sealed and the jars are buried in different places in the garden. Moles cannot stand the sounds of the alarm clock constantly coming from underground and leave the area.
The second option with an alarm clock: place it in a half-meter pipe, buried vertically. Holes are drilled in the bottom of the pipe for better sound distribution. This is what the pipe looks like.
The alarm clock is attached to a wire so that it can be easily reached.
Of all the mole repellers, alarm clocks are one of the most effective methods. The only better repeller is a radio and speakers, but this type requires special knowledge.
Destroy all individuals on the site
If there is only one mole or there are few of them, the pests can be destroyed mechanically:
- track when new molehills appear;
- prepare a shovel and wait until the mole begins to make its way to the surface, forming a mound;
- quickly drive the shovel to the maximum depth next to the molehill and dig out the animal.
A hunted mole is defenseless. It can be taken away from the site into the forest or killed.
You can fight moles by placing special mole traps and traps on the site. The structures are purchased, they need to be dug into the ground or installed in places where the pest constantly appears, as specified by the manufacturer.
If there are a lot of moles, then such methods will be ineffective. There are special teams that carry out gassing of tunnels with toxic substances. You cannot try to do this on your own using pepper spray or household gas, and it can be dangerous for the owner himself. The use of poisoned baits is not used: moles do not feed on grain or sweets and are sensitive to foreign odors.
The use of mole breakers, special electrical devices that are installed in existing tunnels, is also effective. While moving, the mole will be killed by a strong electric shock. The disadvantage of this method is the high cost of the devices, but this way you can destroy pests as they appear over many years.
Advantages of the device
Repelling mice with ultrasound has a number of advantages:
- no need to search for and remove the carcasses of dead rodents;
- there is no danger of poisoning pets with poisons;
- safe for people;
- works throughout the room, no need to update baits.
The electronic device repels not only rats and mice, but also many insects. In parallel with rodents, you can remove ants, cockroaches, and spiders from the house.
A properly assembled homemade ultrasonic mouse repeller works no worse than a factory one, but has its drawbacks. A more effective option is a combined version of the device that generates both ultrasonic and electromagnetic waves.

Storage
In winter or during periods of heavy rain, the mole repeller must be pulled out of the ground. This will extend its validity. But what to do, because when installing the device, you compacted the soil tightly in the area where the mole repeller is located? Customer reviews indicate that it is not easy to pull it out. Especially if its body is made of plastic. You have to dig around the device so as not to damage it.
After being removed from the ground, the batteries are removed from the device and stored until spring. If the case is metal, the storage location should be dry. For a repeller powered by electric batteries, remove the cover and disconnect the wire from the connector.

How to make an electronic repeller
- With the slightest knowledge of electronics, assembling the device is not at all difficult. Large financial costs will not be required either. You need to purchase a microcircuit and transistors. To regulate the frequency of sound, it will be necessary to create an additional unit consisting of resistors, transistors and diodes designed for protection in case of polarity reversal.
- After assembling the device, you need to check the resistance of the resistors so that the load is applied to them evenly; additional installation of a piezoceramic emitter will be required.
- Power supply for the repeller is a standard crown, voltage -9 V.
- The LED flashlight is built into the front of the housing.
- To increase the power, it is advisable to install 8 batteries (AAA standard), capacity 300 mAh, under the crown.
- The essence of the electronic device is the activation of a high-frequency pulse generator when a dog approaches. The frequency is not perceptible to humans, but animals hear the noise of the generator very well.
Do not experiment with the device on your pets; if you point the repeller at them, you may lose their trust in the future. Set the frequency recommended by the manufacturer; if it is exceeded, the device will quickly fail. Typically the device is designed for a range of 30 meters, which will prevent the animal from invading your territory. When choosing a finished device, pay attention to the cost, ease of design, quality of all components, manufacturer’s brand, and production technology. Please note that cheap devices may be ineffective, unreliable, and may not meet the parameters specified in the documentation. Choose an acceptable type of device in advance; if you carry it in your pocket, it is better to buy a portable model. If you need to install it on a tree or wall, choose a stationary device. Cobra is considered a new and high-quality model with 4 operating modes; it can be used as a security system
A small pocket device - Osa, costs only 1200-1500 rubles, is effective and convenient to carry in your pocket. The ultrasonic device with a power of 130 dB is distinguished by high volume. At a distance of 1 meter for a dog, this is the noise of a jet plane, the effect on the animal is simply deafening, thereby you can put it in an aggressive state, you will only make things worse for yourself in particular. Do not rush to use the device if the dog is calm and does not at all seek to harm you. A distance of 4-15 meters is considered large for the repeller to work effectively; it may simply not have an effect on the animal and lose its power at a distance. Consider the range of the device when purchasing or designing a model yourself. Do not panic when an animal approaches, do not make sudden movements. Keep your finger on the button; when attacking, it is better to let the predator get closer, the noise will be deafening, and the shorter the distance, the more effective the device will be. Do not play with the repeller, do not turn it on unnecessarily, for example, pointing it at a quiet, innocent dog. 13.Do not let children play with the device; it is better to teach them how to handle it correctly. Don’t be a provocateur by turning your pet against you; with the device turned on, you can provoke aggression, but why would you want to do that?
Electrical circuit and operating principle
The rodent (mole) repeller is assembled according to the electrical circuit diagram below and consists of only two simple logic chips, a transistor and several passive elements located on a printed circuit board. A distinctive feature of the proposed circuit is low power consumption (a set of three AA finger elements with a capacity of 1 A*h is enough for the entire season), which is due to the emission of an audio signal with a frequency of about 480 Hz for two seconds with a frequency of once every 32 seconds. In addition, this mode of operation of the repeller has a more effective effect on moles and increases the time it takes rodents to get used to the sound.
Structurally, the circuit consists of a clock generator assembled on elements DD1.1 and DD1.2 generating a frequency of about 480 Hz, a frequency divider on the DD2 chip, a logical signal adder on DD1.3, a key transistor VT1 and an audio emitter BA1.
The frequency of the rodent repeller clock generator is determined by the values of resistance R1 and capacitor C1. By decreasing or increasing the value of R1 or C1, you can accordingly increase or decrease the frequency of the emitted sound signal.
From the generator, a rectangular sound signal without changing frequency, through logic element DD1.3 and current-limiting resistor R4, is supplied to transistor VT1, turned on in key mode. In silent mode, a voltage close to zero is applied to the base of the transistor and the transistor is closed. In this mode, the current consumption of the rodent repeller is 0.1 mA. In the sound signal emission mode, the current increases to 22 mA. A simple calculation shows that when using batteries with a capacity of 1 Ah, the mole repeller will work for 9000 hours or 375 days.
The signal from the clock generator is also sent to the counting input (pin 10) of the frequency divider DD2. Based on a positive signal drop at pin 9 of the counter, logical zero changes to logical one. In order to ensure the emission of an audio signal with a period of 32 seconds, a logical unit is supplied from pins 15, 1, 2 and 3 through diodes to the 12 pin of logic element DD1.3, locking it. As soon as a logical zero appears simultaneously at pins 15, 1, 2 and 3 of DD2, DD1.3 will pass a signal from the clock generator to the base of transistor VT1 and BA1 will begin to emit sound.
The chain C2 and R2 is used to set the output voltages of the DD2 chip to zero. When supply voltage is applied to the circuit, capacitor C2 begins to charge and a supply voltage appears at its lower terminal, which is supplied to pin R of the microcircuit. When the charging process is completed, the voltage at its lower terminal will drop to zero and will no longer affect the operation of the DD2 chip. Resistor R3 is a load for diodes VD1-VD4, so that there is somewhere for the current to flow and to eliminate interference in the absence of voltage at pin 12 of the DD1.3 microcircuit. C3 serves to suppress interference that occurs during transient processes in microcircuits.
Options from plastic bottles
The simplest version of a homemade repeller is a bottle placed on a pin. Also suitable for empty beer cans. The pin must be stuck into the ground so that sound and vibration are transmitted to the wormholes.
The most difficult option is a windmill against moles. To make it you will need a one and a half liter beer bottle.
In addition to the bottle, you need good scissors, a marker, a self-tapping screw with threads that do not reach the head, a nail, an awl and a windmill stick. Given the maximum complexity of creating such a mole repeller from a plastic bottle, there are no visual diagrams or drawings. There is only an extremely clear video.
- The bottom of the bottle is cut off along the horizontal line that is found on all plastic bottles.
- The cut bottom is turned over with the bottom up. The bottom has the shape of a five-rayed star. Using a marker, mark the areas that need to be cut out: from the border of the central circle strictly in the middle of the “ray” and from the middle of the central circle along the hollow between the “rays”. This part needs to be cut off. It turns out that half of the “beam” is cut out.
- The operation is repeated on all “rays”. The propeller is ready. All that remains is to punch a hole strictly in the center of the circle. The hole should have perfectly smooth edges and a diameter larger than the provided screw.
- Insert a self-tapping screw with the head “inward” into the resulting propeller and screw it into the center of the bottle cap until the thread runs out. To make screwing easier, you first need to make a small hole in the cap. On the inside of the cover, the self-tapping screw can be secured with a nut for reliability.
- Make two holes for a nail at the bottom of the bottle neck, strictly along the center line. The holes must be strictly opposite each other.
- Take an almost finished windmill and secure it to a wooden pole. Stick the pole into the ground in the garden.
When there is wind, the propeller makes a rather nasty noise, which moles are afraid of. The advantage of a windmill is that it will work in any wind direction. In fact, this is an ordinary weather vane.
The ultrasonic model sends high-power ultrasound signals towards the dog. Ultrasound has a depressing effect on dogs, forcing them to turn around and even run away, while the device is completely safe for humans. As the dog approaches, the signal intensifies and the animal begins to feel discomfort. The device is compact and can be carried with you in a bag or pocket. As the animal approaches, it will react and the signal will increase. With a repeller, a whole pack of dogs is not scary, which is very convenient; you can do without blood and victims. There are a lot of electrical diagrams for this device on the Internet, so if necessary, you can assemble it yourself and buy the components at any radio store. The device is quite simple, and it will cost you much less.
An electric device or stun gun is no less popular. It’s also compact, and when you press the button it produces a characteristic crackling sound, which means that ozone is released, which is unpleasant to a dog’s sense of touch. The device is dangerous for an approaching dog; if the distance decreases, it can give an electric shock and temporarily paralyze
The device will also force the dog to open its jaws if the dog still grabs you.
Gas in the form of a gas canister with a chemical filler inside. When buying a spray can, pay attention to its technical characteristics, since not all products are effective; if a dog attacks, the product may simply fail. When sprayed, the dog should charge, run away and no longer show aggression.
In principle, you can build a gas pistol yourself by filling the cartridges with red hot pepper. You can leave the device idle. Sound is effective against dogs; the device can also be made with a light signal reflector.
Repeller - smell. Everyone knows that dogs have an excellent sense of smell and they do not at all like, for example, the smell of medical or isopropylene alcohol. All you have to do is wet the tampon. But this method has a big disadvantage - the alcohol evaporates quickly, which means you need to carry it with you at all times when going outside. Hot capsicums are irritating to the dog's nose, skin, and eyes, as is the smell of lemon, orange, and vinegar.
The effectiveness of homemade scarecrows
Outwardly, moles look like cute and harmless animals. But at the same time, they can cause significant harm to the garden plot. Moles by nature are blind animals. Thanks to this, their hearing is highly sensitive.
Accurate determination of the permanent habitat can be difficult because the family has several exits from the burrow. Therefore, determining its location is not easy. The task is further complicated by the fact that the depth of the hole can reach several meters. As a result, the right solution is to make homemade turntables from available or scrap materials.
Moles, in addition to causing harm, can also be beneficial. They constantly need food of animal origin. The animals eat beetles, caterpillars and worms in large numbers. Therefore, when deciding on the need to fight, you need to correlate these two facts. In addition, during the digging process, moles loosen and mix the soil.
In addition to the methods described above, you can use simple alarm clocks. You will need a few pieces in total. Clock mechanisms are placed in glass jars and placed in pits. In the process of fighting, you will need to set alarms several times a day for different times. As a result, moles will quickly leave the territory due to the regular and shrill ringing.
To increase efficiency, you can take a medium-diameter polymer pipe and drill many holes. When the clock mechanism is triggered, the hum will spread along its entire length and in all directions. Intense ringing will quickly force ferrets to change their habitat.
Repellers
Taking advantage of the fact that moles are very sensitive to various sounds. A number of manufacturers currently produce electroacoustic devices. First of all, ultrasonic devices. They do not cause any harm to humans, but for moles they become a problem for daily existence on the site.
Among the advantages is the penetration of sounds and other vibrations everywhere, despite obstacles. Typically, such devices operate from autonomous power sources, so they can be placed anywhere in the garden.
Mole traps
In cases where there are really a lot of moles, or for some unknown reason it is not possible to get rid of them using simple methods, mole traps will help. These devices will allow you to catch females ready to breed in early spring.
To determine the location for the trap, you need to press down the mole's passage.
Installation in such areas ensures quick capture of the animal. The main passages are often located in straight directions along fences, fences and foundations. The meandering lines are temporary, so setting traps there will not be effective.
Mole traps consist of several elements:
- input ring;
- pressure lever;
- guard ledge;
- alertness itself;
- spring ring.
The frame is made of a piece of steel wire 3.5–4 mm thick. Between the support and pressure zones there is a spring in the form of a spiral of 2.5 turns. The spring should create a pressing action of 4–5 kg and reliably press the animal to the lower area of the entrance ring with a weight of 2–2.5 kg.
Operating principle:
- When preparing the device, the pressure clamp is raised in the upper direction;
- the design provides for the penetration of the mole to a sufficient depth before the mechanism is triggered;
- the animal touches the horn with its head and thereby releases the clamping device.
Over the course of one day, several animals move along the selected path. At the same time, other individuals bypass the captured animal, making a small undermining. Therefore, along the entire path, you can catch a large number of moles at one time.
The main reason for the invasion of animals into garden plots is the looseness and fertility of the soil. Due to this, the prevalence of pests is highest. Since they are a favorite food of moles, the latter's colonies can be quite impressive.
All of the above methods have been tested many times by experienced gardeners. The production of some of them does not require financial investment at all. But the result will exceed all expectations, and uninvited guests will quickly disappear from the occupied territory.
Gardens and vegetable gardens are a good help both in terms of food and in terms of relaxation for the soul. But everything that is grown on personal plots faces many dangers - beetles, larvae, birds, moles. And if chemicals help fight plant diseases or insect pests, then it is best to scare away birds and moles from the site, rather than destroy them. A primitive design will help with this - a windmill made from a plastic bottle, made with your own hands from scrap materials.
Making a mouse repeller body
It is convenient to make the device based on a cylindrical metal can of coffee, animal food, etc. Repeller assembly procedure:
Advice. It is best to place the printed circuit board in a plastic bag. At the point where the wires exit, tie it with thread.
Instead of a telephone capsule, you can use a purchased piezo emitter. The principle of assembling the repeller in this case will remain unchanged. Only the ultrasonic wave generator will require additional insulation. The can will add additional distortion to the radiation, so the sound of the repeller will seem even more disgusting to rodents and moles. In fact, the metal itself will vibrate, receiving an impulse from the emitter.
Close the jar with a lid. Then bury it in the chosen location. The depth is approximately half the height so that water does not get under the repeller cover. It is far from ideal in terms of tightness.
Be prepared that you won’t be able to eliminate the pests right away. Time must pass - up to 2 months. If you plan to place the repeller indoors, make it more powerful. Walls and other obstacles will reduce effectiveness when the sound is low.
Other pets may also react negatively to the waves. In this case, adjust the frequency. Experiment with this at the stage of assembling the repeller circuit.
Criterias of choice
Some devices have a universal effect, so they can affect a wide group of biological beings. Such gadgets are sold in specialized supermarkets.
Manufacturers note that there is no point in chasing ultra-modern mole repellers, since all of them, by and large, are ideal for getting rid of mice and rats. Autonomous mechanisms that generate sounds of varying vibration frequencies at certain intervals are considered more convenient to operate.
In most cases, they are considered not only the most convenient, but also effective.
When purchasing a device, you must adhere to the following rules:
The first step is to carefully study which rodents the device is designed for, read the detailed characteristics and reviews of experienced users.
Compare the territory indicated on the device with your territory.
It must be borne in mind that the area is always designed for an empty room, so you should rationally assess the workload of the room. You need to pay attention to the purpose of the territory.
The device is capable of providing a repellent effect for approximately 2 months. In a non-residential area, or if there is no food in it, the effect is achieved twice as fast. The purpose of the premises must be taken into account.
If you have pets in your home, you should only choose devices with ultrasound that they cannot hear.
Foreign brands are best suited for this.
When purchasing several gadgets for different homes, you need to keep in mind that some of them are specially designed to work in rooms with low temperatures. Such devices include the “Tornado”, “Spectrum” and “Sonar” models.
