When summer cottages are covered with heaps of freshly dug earth, it’s time to think about acquiring or creating a do-it-yourself device for killing moles. These cute animals can cause a lot of trouble. Their orientation in space due to the organs of hearing and smell prompted manufacturers to create devices with ultrasonic and vibrational radiation. We will talk about the popular types of repellers, the principle of their action, how to choose an ultrasonic mole repeller, and how to make the device at home.
What’s this
A small animal with smooth gray fur and paws with sharp claws, which feeds on earthworms and insect larvae, digs entire underground labyrinths in the soil. In the course of its activity, the mole undermines the roots of plants that interfere with it, after which they die. If earlier you had to catch the animals with your own hands, now modern repellers come to the aid of summer residents. Such devices were invented to protect sites from moles, shrews and other small rodents that cause irreparable damage to vegetable gardens, orchards, fields.
Repellers can be installed outdoors and, if necessary, this is done indoors. When choosing the first option, the device is placed in a hole, with the second, it is located towards a piece of land. Repellers can be used in poultry and livestock farms, in storage facilities, in the premises of shops, cafes, and sanatoriums. They are also used to protect basements and cellars from the vital activity of moles and shrews.
Types of repellers
The principle of operation of special technical devices is based on the increased sensitivity of rodents and shrews to vibration waves and loud sounds. Devices create various effects that repel pests.
Among the types of devices are called mechanical, biological and ultrasonic. In mechanical design, the presence of an eccentric is a mechanism in the form of a disk that generates special vibrations. Its center is somewhat offset relative to the axis of the main shaft, which creates a resonance that leads to vibration. A bio-type agent diffuses the scents of essential oils from the substance that is included in the balls. Ultrasonic devices operate on the basis of vibrations of the emitter.
According to the type of power source used, there are solar-powered devices, conventional batteries, combined (they can work on both solar and simple ones). Solar-powered devices do not require changing a set of batteries, which is very convenient. In the upper part of such a device is a solar battery that accumulates an energy charge. Due to this, the device is active even at night. The effectiveness of the devices consists in the formation of sound vibrations that are not audible to humans but represent a barrier to moles. Ultrasonic waves propagate in the range from 36 to 45 meters.
Consider the best models of repellers in more detail. An excellent functional tool is Tornado OZV 01. It creates sound vibrations that are unpleasant for moles and small rodents. Tornado OZV 01 is powered by rechargeable batteries. The area of its influence is 1000 square meters, the range of optimal temperatures is from 0 to 50 degrees. Tornado OZV 01 operates within the frequency of 400 Hz. Having improved the Tornado OZV 01 model, manufacturers introduced a new repeller on the market – Tornado OZV 02. The principle of operation of the Tornado OZV 02 device is to generate vibration waves.
The oscillations occur a couple of times per minute. The duration of the signals of the Tornado OZV 02 device is up to 40 seconds, the range of influence on moles is up to 25 meters. The range of model 02 depends on the degree of conductivity of the earth and the terrain. One device Tornado OZV 02 protects a piece of land up to 10 acres. The model 02 device is powered by 4 R20 batteries, which will last for 3-4 months. Tornado OZV 02 effectively works against moles, bears, ground squirrels, shrews, field mice. Tornado OZV 02 is easy to use, it will become your reliable assistant.
The Grom-Profi repeller has a generator of mechanical vibrations in the form of a built-in vibration motor. This enhances the performance of the speaker and increases the efficiency of the Grom-Profi device by more than 25%. The operation of the Grom-Profi device is based on the principle of mechanical amplification of vibrations in order to increase the radius of impact. Thunder-Profi works great against moles, snakes, rats, mice, shrews. The advantages of the Grom-Profi device are a large impact area – up to 1500 square meters, a built-in mechanical vibration generator – a vibration motor that enhances the efficiency of the sound emitter, creating earth vibrations that are unpleasant for pests.
Thunder-Profi shows its effect regardless of the weather – the hermetic moisture-repellent body of the product is made of durable aluminum. The Grom-Profi M device consists of an aluminum rod 40 cm long, a cover and a plastic tip, powered by 4 batteries. The kit is enough for normal operation of Thunder-Profi for up to six months.
Detia is available in a convenient form of balls, which should be evenly distributed over the area in areas where underground pests are active. The consumption of Detia is from 0 kg per 3 square meters. Granules can be watered or wait for rainy weather. The Detia granules will gradually dissolve and exude a mole-irritating aroma.
This is a natural product made on the basis of castor oil, corn grains, soap. To make the moles move in a certain direction, it is recommended to process the territory of the site sequentially, first covering a third of it. If you process the area from the end opposite to the direction of movement and water, after a few hours the pests will begin to move in the given direction. You can spread the granules manually, use a manual spreader, or use a traditional spreader, turning it on to the minimum product flow rate.

How to choose
What repeller to buy to treat your site from pests? Technical devices should be selected according to such criteria. Pay attention to the type of power supply of the device. It is advised not to purchase a solar-powered repeller if it often rains or there are cloudy days in your area. Then choose a device that runs on conventional batteries. But in this case, they will need to be replaced after 3-4 months. It is important to choose and type the device correctly. An ultrasonic unit against moles, shrews and rodents, which operates on solar panels, is a less expensive option.
Since biological devices require periodic replacement of the main active component, the technique should be chosen, focusing on the area of influence.
These parameters will be indicated on the package, after reading which, you will make the right choice. When choosing a device, it is important to pay attention to the frequency range and the ability of the device to produce changing vibrations so that pests do not have time to adapt to them.
How to Make Your Own Hands
If you have enough desire and patience, you can try to make a simple device that looks like a repeller with your own hands. A tin can is suitable, which is put on a metal rod. It should be installed on a personal plot in places of activity of malicious underground inhabitants. A more interesting option is the design, which is created from plastic bottles. Metal bars should be installed on the site, each of which is put on a plastic bottle.
In order to create a tangible sound effect, peculiar blades are cut out on the walls beforehand in each instance. At their expense, noise will be reproduced on the site when the wind blows. Home-made devices in order not to spend money on the purchase of ready-made devices are created by many prudent site owners. Which soon manage to be convinced of their weak efficiency in comparison with modern ultrasonic, mechanical and vibration units.
