Sound repeller for birds and animals Thunderbolt DBS-E

Nowadays, almost every family has pets. As a rule, these are cats or dogs. Unfortunately, not all owners are ready to take responsibility for their pets, so they often end up on the street. This gives rise to the emergence of new individuals, which can then cause inconvenience and even pose a danger to people. There are often cases when dogs, gathering in packs, attack passers-by.

In suburban villages the situation is similar: dogs can get into the area in search of food or scare someone on the street. Manufacturers have developed a modern device specifically so that when meeting a flock a person feels safe and can defend himself if necessary. Its name is repeller. Such devices are available in 3 types:

1. Gas (aerosol) ones resemble a regular pepper spray, only with different contents. Relevant only in case of an animal attack, because operate at a minimum distance. It is enough to spray a small amount in front of the dog's face so that the animal feels irritation in the eyes. The main disadvantage is that they do not prevent attacks.
2. Electric repellers are small in size, easily fit in your hands and work on the principle of a stun gun. In direct contact with the dog, a special button is pressed, which releases a charge of current in order to immobilize the animal for a while. The main disadvantage is the same as that of a gas repeller - it only works during an attack, and not before it. But it has several more disadvantages: if used carelessly, it can kill an animal or harm a person.
3. Ultrasonic repellers are the best option. They work over a long distance (up to 30 m) and act through special waves that cause discomfort to dogs and force the animal to leave. There are two types - pocket and stationary. The former are more often used in the city, while the latter are installed in the private sector directly on houses.

Ultrasonic repellers are considered the safest for animals and most effective for humans. Therefore, we will dwell in detail on this type of device and consider the best models from the most popular manufacturers.

The Best Pocket Ultrasonic Dog Repellers

Choosing a dog repeller is not an easy task. Nowadays you can find a huge number of different models in stores. But if you know for sure that you will need the device far from home on the street, then a pocket repeller is what you need. The portable device has small dimensions, light weight, and shock-resistant housing. Some models are equipped with additional means of protection (sound and light signals). It can really help when dealing with aggressive dogs. We studied customer reviews and found out which repellers are considered the most effective.

Model selection

Experts assure: if the device is chosen correctly, it is guaranteed to drive uninvited guests out of the house. To avoid making a mistake with your choice, consider five important points.

1. Wave range. When choosing an ultrasonic repeller, pay attention to the frequency indicated in the instructions. If the device includes a 16 kHz indicator, then it is better not to purchase it, since such sound is picked up by the human ear.
2. Changing mode. Consider one more feature. Ultrasonic repellers can operate in one mode or in several. Moreover, the change in waves in some devices occurs automatically. The most effective are those devices in which the ultrasound changes independently. The constant change of waves does not allow rats and mice to get used to the unpleasant sound.
3. Room area. Consider the size of the room. Manufacturers must indicate in the instructions the power of the device and the area covered. However, remember that we are talking about an empty room. If the room is cluttered with furniture and carpets, then it is better to choose a more powerful repeller.
4. Captured territory. If rodents are attacking your home, you will need a device that plugs into an outlet. But sometimes pests settle in the chicken coop, cellar, barn and even in the garden. In these cases, it is not always possible to connect the device to the network. A battery-powered repeller will save the situation. And if you live in a private house and periodically suffer from rodent infestations in your rooms and area, choose a universal device that can operate on both electricity and batteries.
5. Duration of the fight. On average, rodent control lasts two to three weeks. But if pests have settled in the room where food is stored, they will not retreat so easily. Therefore, expect a longer battle, approximately two months.

The best stationary ultrasonic dog repellers

Stationary repellers are usually larger in size than pocket repellers, but at the same time they have more extensive equipment and higher efficiency. They are attached to fences, house walls, poles, etc. Designed to repel not only dogs, but also other animals (various garden pests, etc.). An important advantage of some models is charging from solar panels. This saves battery costs and is very convenient to use. We found out which stationary ultrasonic frighteners are the most useful.

Review and characteristics of popular devices

There is a huge range of repellers on the market. They vary in design, power, and area covered. Before making a purchase, be sure to check the operation of the device. If you hear a sound or feel slight discomfort, do not purchase. Otherwise, you may experience all the side effects.

In the first days after connecting the device, there is a real invasion of rodents. Therefore, most owners are sure that the device is not working correctly. This is a misconception. The repeller causes disorientation in tailed pests, and they are quite capable of “getting lost” in space and leaving their holes. Starting from the third to fifth day, you will notice a decrease, and soon the complete disappearance of rodents.

Choose by power – the more the better

Proving the effectiveness of a repeller by measuring power is one of the most favorite methods of sellers. They buy different equipment, create tables and offer them to users. But this is the wrong choice - you cannot compare devices that operate under different conditions. For example, there is an effective repeller for covering an area of ​​45 m, which will not work on 50 m. It is impossible to place the Tornado 800 and Tornado 400 devices next to each other - the same body does not indicate complete identity, since the ultrasonic speakers are different.

It is wrong to choose an effective repeller based on the power of sound radiation. Devices are selected based on a whole range of characteristics - coating, area of ​​influence, application, type of animal, etc.

How does ultrasound affect insects?

Insects are arthropod invertebrate animals that have a very hard chitinous cover, which is essentially an external skeleton. Chitin, by the way, in some insects is one and a half times stronger than steel. Under the exoskeleton is living tissue consisting of layers of fat and hemolymph.

The chitinous plates of insects can resonate, they vibrate even under the slightest mechanical influence of external conditions, including acoustic waves, and the gel-like composition of the tissue enhances this effect. Here we should remember the laws of physics, according to which mechanical vibrations are transmitted in liquids at a much higher speed than in other media. For example, the speed of sound in air is a little more than 330 meters per second, and the speed of sound in water reaches 1485 meters per second.

Interestingly, the effect of high-volume sound waves on insects can be compared to the low-frequency shock wave of a subwoofer in a car or a bass guitar at a rock concert, which are not only heard, but physically felt in the stomach.

However, unlike insects, human skin is an excellent sound absorber, and it dampens ultrasound, while chitin resonators, on the contrary, enhance it. The result of such exposure is both painful sensations in arthropods and the failure of certain systems and organs.

The sound spectrum is divided into three areas, in our case it is the red sector

Among other things, ultrasound is perfectly reflected from dense, and especially smooth, surfaces, which include walls, ceilings, floors, wooden or plastic furniture in a room, which implies a continuous, multiply amplified acoustic attack on insects anywhere in the room where there is such type of radiation.

Why buy more expensive something that is cheap?

If there is demand, there will be supply - this is the law of the market. Often supply exceeds demand several times, and careless manufacturers take advantage of this by offering obviously low-quality goods. Ultrasonic repellers are no exception - they are stamped “on the knee” and sold for 500 rubles. The consumer compares prices, sees that the company sells an effective cockroach repeller for $20, while it is offered on the market for $2, and buys what is cheap.

As a result, the device does not work, at best it only blinks the lights, and cockroaches roam freely around the house, even after a week or more. The point is not that ultrasonic repellers do not work, but that they bought something else, but not a high-quality device.

A good and effective cockroach repeller will also not remove all insects in an hour or a day, but after 10 days they will be gone - that’s a fact. The fake will wink with green or red lights and will serve as a good decoration for the Christmas tree, but you shouldn’t expect anything more from it.

The conclusion is to buy really high-quality devices from the manufacturer, and ask in advance for all the certificates, studies, etc. In particular, effective Tornado repellers were developed in the USSR, today our company produces them, relying entirely on the documents given to us.

Operating principle

A modern device that repels insects and rodents must be connected to an outlet. The high-frequency sounds it emits have a negative effect on pests.

They experience stress, confusion, seizures and sometimes death. The constant stress that pests experience from the high-frequency device does not allow them to reproduce and eat. Therefore, they move out of its radius of action.

It can be concluded that the operating principle of an ultrasonic trap is based on the instincts of insects and rodents that communicate through a high-frequency signal.

Research has shown that the mechanism that imitates the signal of a bat is most effective against insects, because the bat is their main fighter.

Research is done by smart people, so you have to trust them.

Of course, but only after the scientist confirms his degree and provides all the calculations and documents of his research. A high school student will be able to put on a white coat, glasses, put the retort on the alcohol lamp and draw a graph on the board. No sane person will trust such “research”. Therefore, before taking all the calculations on faith, it is worth familiarizing yourself with the data on laboratory work, etc.

You should only trust trusted manufacturers. It is desirable that the research be confirmed by certificates and carried out in domestic conditions. The requirements of Western and Russian users are different, so an effective repeller, according to a European, is not always an indicator of the excellent quality of the device.
