Of all the currently existing methods of combating household pests such as cockroaches, the most effective is considered to be disinfestation of the contaminated area with pesticides. However, it is not possible to use poison always and not everywhere, and here special devices - repellers - can come to the rescue.

• 2 Ultrasonic devices
  2.1 Do cockroaches experience a sense of fear when using ultrasound?
• 2.2 Advantages and disadvantages of ultrasonic devices
• 2.3 Rules for operating the cockroach repeller

Types of repellers

The main purpose of these devices is not to destroy, but to create conditions unbearable for the life of pests. Most often, repellers are used as part of a set of preventive measures, collectively called “barrier protection.”

The devices affect the sensory organs of cockroaches through signals of a certain intensity and frequency. Based on the type of radiation, repellers are classified as ultrasonic and electromagnetic. There are also combined gadgets that combine these technologies and have additional options.

Electrofumigators, which work effectively against small flying insects, however, have little effect on the behavior of cockroaches. In addition, most of these devices are designed to destroy pests, so these devices can only be classified as repellers conditionally.

Principle of operation

A cockroach repeller is a device that helps get rid of insects using ultrasound, aromatic substances or electromagnetic waves. The device is connected to an autonomous power source or a fixed network and creates an aggressive environment for cockroaches and other pests. Ultrasound (or electromagnetic waves, depending on the device) affects the insect's nervous system, forcing it to leave its habitat. It is worth remembering that the repeller is not capable of completely destroying pests, so it is better to use it in combination with other means.

Ultrasonic devices

Ultrasound is considered to be acoustic waves whose frequency exceeds 20 kilohertz. Ultrahigh-frequency radiation today is widely used in medical technology and production. The human ear is not capable of perceiving very high frequencies, but some animals and insects use ultrasound to transmit information to each other and react to it.

Ultrasonic devices, according to the developers, work effectively against a wide variety of pests

The described feature made it possible to use ultrasound to repel pests, including cockroaches. However, in this case, more questions arise than answers, because the latter practically do not react to sounds and communicate through direct physical contact and chemical secretions.

The operating principle of an ultrasonic repeller is quite simple. When power is applied, the electronic filling of the device generates pulses of the required amplitude. A sawtooth voltage is supplied to a special sensor (piezoelectric element or dynamic head), which generates the final acoustic signal.

Do cockroaches feel fear when using ultrasound?

Manufacturers of ultrasonic devices note that when the repeller is turned on, cockroaches experience a feeling of fear and panic, trying to leave the dangerous territory as quickly as possible. In light of the fact that pests do not have organs for perceiving such signals, this statement may be very doubtful.

An effective cockroach repeller must have sufficient power

On the other hand, some users still note a certain effect from the use of high-power ultrasonic repellers, but the operation of such devices is permissible only in the absence of people. Thus, we can conclude that the effectiveness of household ultrasonic repellers in the fight against cockroaches will most likely not be high, but this method is applicable in conjunction with other measures to control and prevent the appearance of pests.

Advantages and disadvantages of ultrasonic devices

Among the positive aspects of using ultrasonic cockroach repellers are:

• ease of use - the devices do not require any specific maintenance and care;
• safety in relation to people (there is a conflicting opinion of experts);
• environmental friendliness - the devices do not emit harmful or toxic substances.

The disadvantages of ultrasonic cockroach repellers are:

• their unsafety in relation to pets - especially small rodents (hamsters, mice and rats) and birds;
• most often low efficiency;
• quite high price - especially for the so-called professional models.

Rules for using a cockroach repeller

You can achieve a certain effectiveness of the repeller by adhering to the recommended rules for its use.

The ultrasonic cockroach repeller is placed at a height of 1–1.5 meters from the floor

User manual:

• use not one, but several devices at the same time. This approach will help get rid of insect colonies. Ideally, you should place an appliance in each room;
• The repeller should not be installed level with the floor. By raising the device to a height of one meter, you will significantly increase the area of ​​its impact;
• in a room cluttered with furniture and other interior items, the effectiveness of the ultrasonic repeller is reduced. The way out is to install two or more devices indoors;
• While using the gadget, you need to monitor your condition, the condition of other people, especially children, as well as the behavior of pets. If anyone becomes ill, you should stop using the repeller;
• If damage or malfunction is detected, the device should be repaired or replaced. Using a faulty device is unacceptable;
• use the repeller in combination with other methods of control and prevention. The main remedy, for example, may be a special insecticide;
• According to manufacturers of ultrasonic repellers, the effect of using the latter is not immediate. You should wait one to three weeks;
• The device must operate continuously and cannot be disconnected from the network. Otherwise, the cockroaches will most likely return.

Measures to prevent the appearance of cockroaches

It is not enough to install cockroach repellers; you need to create the most uncomfortable conditions for the subsequent appearance and reproduction of pests. As soon as domestic cockroaches appear, you should get rid of the uninvited guests. Prevention is as follows:

1. Conduct a general cleaning of the premises (if possible). Remove food from public access, shake all bags of cereals and pasta. The easiest way is to place supplies in airtight glass or plastic containers. Pay special attention to bread, pastry and sugar - these are the favorite delicacies of pests.
2. Check the pipeline for leaks. The main areas where insects are located are damp and dark places. Cockroaches need a source of water for rapid growth and raising offspring.
3. Do not leave dirty dishes with food out overnight, put food away, clean out cabinets, and keep the kitchen, bathroom, and powder room clean. Crumbs on the floor will quickly attract hordes of pests, but getting rid of them will be more difficult.
4. In damp rooms, ensure good ventilation. Condensation on the walls, remnants in the soap dish, rot in the area of ​​pipe joints, mold - all this is the favorite food of insects.

If a garbage or ventilation shaft in a multi-story building is clogged and has not been cleaned for a long time, it is a breeding ground for insects. A cockroach repellent device will help here for a short time. To clean the channels, be sure to call a technician from the management company. In order for the cleaning to be done quickly, you need to write an application addressed to the director of the management company - according to the law, the director is obliged to respond to the signal and put the common property in order as quickly as possible.

It is interesting that in private houses made of wood, cockroaches practically do not appear. But here you can find various woodlice, spiders and other equally unpleasant guests in abundance. The electronic repeller also works against these “neighbors”, and at the same time will prevent the appearance of “red mustaches”.

Popular ultrasonic models

Ultrasonic repellers can be used both at home and at work. Often these devices are universal, that is, they work against a wide variety of pests.

Typhoon LS-500

The ultrasonic repeller Typhoon LS-500 allows you to fight various types of insect pests, these are:

• fleas,
• ants,
• cockroaches,
• bedbugs.

The Typhoon LS-500 device causes discomfort and a feeling of panic in insects
. According to the manufacturer, the device causes discomfort and a feeling of panic in insects. Pests try to leave the dangerous area as quickly as possible. Additionally, the device affects cockroaches with light radiation and an audio frequency signal in the audible range (makes clicks). The complete disappearance of insects occurs in the second or third week of continuous operation of the LS-500.

The repeller can be used on objects such as:

• household premises - living rooms, kitchens, bathrooms;
• utility premises of various kinds - warehouses, change houses, catering establishments and the like.

The device operates from an electrical network with a voltage of 220 Volts. The built-in microcontroller automatically changes the sound frequency and duration of ultrasound radiation, so cockroaches cannot adapt to unfavorable conditions for them.

Reviews about Typhoon LS-500

I also bought this one. I was watching TV and an advertisement started advertising the ultrasonic cockroach repeller Typhoon LS-500. And of course I wondered what it was, since we live in an apartment and sometimes suffer from these cockroaches. What can I say, a highly advertised device that does not perform its functions. My cockroaches lived in the kitchen and stayed there, they didn’t run away anywhere. Wasted money.

The device worked for me for about a year and during this time I never saw cockroaches. However, beetles and spiders periodically delighted me with their presence. Therefore, we can say that the device has no effect on insects in general. After I turned off the Typhoon ultrasonic repeller, 4 years have passed. During this time, I met cockroaches in the kitchen 1 or 2 times.

Weitech WK-0600

The manufacturer positions the Weitech WK-0600 ultrasonic device as a powerful professional means of combating pests and rodents. First of all, the device is recommended for use in non-residential premises of industrial and commercial enterprises, warehouses, bases, and in the holds of ships. WK-0600 can also be used at home, but in the absence of people and their pets. Thanks to the increased power, dual emitter and protection from adverse environmental conditions, the gadget is suitable for use in open areas.

The effectiveness of the technologies used in Weitech WK-0600 has been confirmed by tests in independent laboratories

Weitech WK-0600 has several operating modes. Adjustment is carried out both in range and in the level of the emitted signal. In the presence of people, it is recommended to turn on the device only in the so-called “quiet mode” with reduced power.

According to the manufacturer, the repeller affects the nervous system of pests, forcing them to leave the protected area.

User reviews

The Weitech WK-0600 ultrasonic rodent and insect repeller is a complete deception of honest people. With the money I earned, I bought a Weitech WK-0600 ultrasonic rodent and insect repeller last year. I really hoped for the advertising of this miracle device. I turned it on several times a day, left it on longer than recommended in the instructions, and had zero effect. I don’t know about rodents (I poison them in the usual traditional way), but there are no fewer insects in the house.

Katushka30

https://otzovik.com/review_498500.html

Today, once again, I received an ultrasonic rodent and insect repeller Zenet XJ-90 at the request of my daughter. She studies at the university and lives in a dormitory. And imagine that cockroaches have the most freedom there. I and all my neighbors and friends who encountered a similar problem used this device. Now I decided to help my daughter and her dorm friends get rid of this disaster. We also had a time when you couldn’t sleep at night for fear that a cockroach would fall on you from the ceiling or crawl along your arm. And the constant washing of tables, cabinets and refrigerators from traces of these disgusting cockroaches. We tried all sorts of methods: the whole apartment was outlined with “Chinese pencils”, we barely saved the cat because he ate several potato balls with boric acid, and what effort did it take to constantly wash the whole house of poison and pencil... Looking at all this simply It is impossible to maintain peace of mind. But now we're okay. We got rid of the cockroaches.

Tornado OT-01

Tornado OT-01 is a Russian product made from Chinese components. Whether this is good or bad is ultimately up to the users of the device to decide, but according to the majority, the device does not cope very well with cockroaches.

Ultrasonic repeller Tornado OT-01 is one of the developments of the domestic enterprise LLC MNPF Center New Technologies

Despite the not very positive reviews, OT-01 can be used to prevent the appearance of pests and to combat them together with chemicals. The device has a fairly compact size and is not very heavy. The body is made of black plastic. There is an indicator of the repeller operation. The device operates from a network with a voltage of 220 Volts.

Reviews about Tornado OT-01

Works! I bought it for testing, since the chemistry didn’t really help. The device had a strange effect: in the first three days, cockroaches crawled out from wherever possible, it even began to seem that there were more of them. I called the store to find out what it was. They told me that this is how it should be, and that the cockroaches will soon leave. And indeed, 8 days have passed and there are much fewer cockroaches!

User reviews

We bought a universal ultrasonic and electromagnetic repeller of rats, mice, ants, cockroaches, ticks, fleas, spiders and crickets EMR-25. My impressions: If the cat heard it, it didn’t react. The device buzzes only if you bring your ear close to it. The night light is nasty, blue, but slightly illuminates the room. In general, his presence is not particularly felt. Used it for two months. The result is promised in 2-3 weeks, on some resources - in four. And so: The mice, as promised, activated: they began to throw themselves out of the cracks and were finished off by the cat, they began to crap more, a couple of times some stupefied individuals came out and stood, thinking about life (the cat was ready) And then nothing. As they galloped, they still gallop to this day. Insects: cockroaches and mosquitoes don’t really care about this thing. Spiders also walk around the house wherever they want.

Table: characteristics of ultrasonic repellers

Why may electrical devices from cockroaches not work well?

Electric cockroach repellers do not always give the expected results. The lack of the required effect may occur for the following reasons:

The above reasons indicate that electric repellers also have their drawbacks and to obtain a guaranteed and 100% result, it is best to combine them with other proven means of control (chemicals, folk recipes).

Tips for choosing the right model

When choosing an ultrasonic repeller, experts advise paying attention to the following points:

• In the case of a residential apartment or house, purchasing a heavy-duty device is not a good idea. Or residents will have to leave the premises while the device is operating (which is 3-4 weeks). On the other hand, a device with low power is less efficient;
• There are repellers with an impact area of ​​up to one square kilometer, but such devices are again recommended to be used only in non-residential premises and open spaces. An alternative option is several repellers with an impact area of ​​25–50 square meters, one per room;
• In order not to run into fakes, it is recommended to purchase gadgets in specialized stores or from official dealers of the manufacturer.

How to choose

To avoid making mistakes when purchasing a repeller, you should consider:

• Radius. The area of ​​propagation of ultrasonic and electric waves depends on the size of your apartment or other type of housing. Coverage on average from 60 to 500 sq.m.
• Functions. If you need a repeller solely for prevention, then it simply doesn’t make sense to take frost-resistant devices with a high frequency.
• Consumption. Devices of this type consume little, but pay attention to the number of watts consumed, otherwise a considerable amount can accumulate in a month.
• Price. The price tag of the repeller depends on the rooms in which it is intended to be located and with what frequency it works. But the fewer square meters are covered, the correspondingly lower the cost of the device should be. Please note in advance to avoid overpaying in the future.

How to make an ultrasonic repeller with your own hands

You can assemble an ultrasonic repeller with your own hands if you have at least basic knowledge of radio electronics. The schematic diagram of such a device is shown below.

The specified parts can be replaced with any domestic or imported analogues

As you can see, the device includes thirteen elements, namely:

• fixed resistors R1, R2, R3, R4, R5;
• trimming resistor R6;
• piezoceramic sound emitter BQ1;
• transistors VT1, VT2;
• non-polar capacitors C1, C2;
• diode VD1;
• switch S1.

Parts can be purchased at a radio store or, if possible, obtained from an old radio or TV. You will also need foil PCB for the printed circuit board. The latter is made by chemical etching.

You can do without making a printed circuit board by mounting it using the hinged method.

The key elements of the device are transistors VT1, VT2, which generate an electrical signal of the required frequency and power, and a piezoceramic speaker BQ1, which directly emits ultrasound. Trimmer resistor R6 adjusts the frequency of the ultrasonic signal. Toggle switch S1 turns the device on and off. The power source is a battery (battery) or power supply. The circuit operates stably at a voltage of 4.5–12 V.

According to reviews from users who assembled this homemade ultrasonic repeller, the desired effect was observed against both insects and rodents. That is, the device is universal. In this case, it is important to select the required ultrasound frequency as accurately as possible by connecting an oscilloscope to the output of the device.

The finished board can be mounted in any suitable case

Effect on the body of insects

Electronic cockroach repellers An electronic cockroach repeller produces ultrasound of a certain frequency.
The human ear cannot detect it. According to manufacturers, the work of the exterminator does not affect the well-being or health of a person, therefore the products are classified as safe. Ultrasound prevents insects from finding food, a pair for mating, and does not allow them to orient themselves in space. Ultrasound can repel some insects, but not cockroaches. The mechanism of action on Prussians is somewhat different.

Interesting!

There is also an ultrasonic trap that does not repel insects, but attracts them to itself. The pests approach the sound source; there is a grid on it with an electric current supplied. The insect receives a shock and dies instantly. In this way it is capable of destroying all flying insects. An example of such devices is the Terminator lamp range.

Electromagnetic devices

Electromagnetic repellers use a different principle of influencing pests. The operation of this class of gadgets is based on the generation of low frequency electromagnetic waves. The radiation spreads along the electrical network wiring, thus covering all rooms in the house where electricity is installed.

Just like ultrasonic devices, electromagnetic repellers only affect cockroaches while they are turned on.

Household appliances that emit low-frequency electromagnetic waves are often not powerful enough to seriously harm insects. In particular, this is due to the strict safety requirements. An increase in output power has a positive effect on the effectiveness of repellers, but at the same time the danger of exposure to radiation increases.

Powerful electromagnetic repellers can be used indoors only in the absence of people, so their use has become more widespread in industrial enterprises, warehouses and bases. However, even quite expensive professional devices do not provide a 100% guarantee of complete elimination of pests.

Inexpensive and ineffective household repellers can be used as part of comprehensive control and prevention of cockroaches together with insecticides.

EcoSniper AR-120

The AR-120 model is a device using the magnetic resonance radiation principle. The device operates stationary.

According to the manufacturer, studies have shown that EcoSniper AR-120 does not have a harmful effect on humans and domestic animals, while being a powerful irritant of the nervous system against pests such as:

• ants,
• cockroaches,
• fleas,
• spiders.

The EcoSniper AR-120 device may be useful where it is not possible to get rid of cockroaches using traditional methods.
The device does not emit any harmful chemicals. Can be used simultaneously with insecticides. Other features include:

• no influence on the operation of electrical wiring and other devices,
• the device does not generate radio interference,
• There are built-in indicators to monitor the operation of the gadget.

EcoSniper AR-120 can be used at such facilities as:

• Living spaces,
• public catering places (including catering units),
• kitchens,
• clinics,
• warehouses and bases,
• farms and livestock farms.

Reviews about EcoSniper AR-120

I liked the fact that the repeller acts not only with ultrasound, but also propagates waves along electrical wires, that is, exactly where these parasites crawl. What must I say, in the first 2 weeks the result was very doubtful, of course we were warned that we needed to wait 2-4 weeks for the effect, but like a real Russian person, I want everything at once! In general, after 2 weeks of waiting, we began to get the first results, the cockroaches became fewer and fewer, and after a month they completely disappeared. So far we have been living without problems for 2 months, we do not remove the repeller from the socket, it does not interfere, let it be for prevention.

We moved to a new rented apartment, it seems to be in good repair, entrance. But the neighbor let us down, he got a drunkard who didn’t have any living creatures in his apartment. People came to him to poison his insects, and they rushed to us! My wife and I grabbed our heads, we were already getting ready to move out - who would like such a neighborhood? We decided to try the cockroach repeller, of course we expected the effect from the first day (you need to read the instructions properly), we were even upset that nothing happened in the first 3 days. But on the fourth day there were fewer of these bastards! And after 2 weeks they disappeared completely!

Riddex was recommended to us by friends whom we visited and noticed this device. They said the cockroaches had completely disappeared. We ordered from the online store and waited. I dreamed that as soon as I plugged it into the socket, I would see cockroaches dying in convulsions and their complete destruction. But it wasn't like that. They connected it, it worked for 2 months. It was promised that in 2 months the cockroaches should disappear, but they kept running and running. I turned it off and put it in a drawer. They started poisoning in other ways, with dichlorvos, poison from the Colorado potato beetle, they already planned to call the sanitary and epidemiological station, so another 3 months passed. And then I remembered about Riddex, I remembered that when it was connected, there were still fewer cockroaches. We plugged it back in, and then I noticed that it was still working, I constantly found dead cockroaches on the floor, they began to crawl less than before. But they are not completely destroyed, during the day they are not visible at all, and at night there are a couple of them running around in the kitchen, which I kill whenever possible.

The electromagnetic repeller EMR-21 is a universal device and will help you cope with such annoying neighbors as rodents and harmful insects.

According to the manufacturer, EMR-21 is characterized by maximum efficiency and safety

Two LEDs of different colors serve as indicators of the repeller's operation. Green lights up when the device is turned on, red signals the beginning and end of the working cycle. The instructions for use for the device emphasize that it is not advisable to use the gadget in a room where there are decorative rodents. No negative effects on humans during operation of the device have been identified.

Reviews of EMR-21

It helped me, all the cockroaches went to the neighbors. I also offered them, but they don’t have the money yet. We live in a hostel.

We live in a private house in a village, where there are of course a lot of insects and whatever you want, these are ants, flies, mosquitoes, cockroaches, and various bugs. With the birth of the baby, we immediately bought an ultrasonic repeller, we have been using it for more than a year, it works effectively and we forgot what insects are in the house, the baby and we sleep peacefully at night, forgetting that a mosquito or fly might fly in, nothing interferes with our sleep. It is also very convenient, the repeller glows like a flashlight at night, everything is visible, the baby has already grown up and we don’t have to turn on the light at night.

Table: characteristics of electromagnetic devices

What manufacturers say

Commercials strongly recommend installing an ultrasonic cockroach repeller in your apartment. Since this is not the most budget-friendly purchase, you need to carefully study the information that manufacturers provide about their devices.

How it should work

Apartment owners, desperate to get rid of red pests using usual means, place great hopes on an electronic cockroach repeller. The manufacturers themselves describe the operating principle of the ultrasonic device as follows:

• by inserting the anti-cockroach device into a socket, the user activates high-frequency waves;
• insects, picking up signals, begin to panic and inform each other about the danger;
• with prolonged exposure to an electromagnetic field, coordination of movements occurs, insects lose interest in eating and mating;
• pests leave the premises - as the living conditions in it become unbearable.

Ultrasonic devices have low energy consumption. They can be connected to the network around the clock, without the risk of damaging the family budget.

How inefficiency is explained: 5 user mistakes

In response to increasing negative reviews of electromagnetic cockroach repellers, manufacturers have suggested that the users themselves are partly to blame for the ineffectiveness. Five errors are identified.

1. Inattention. Perhaps the buyer was careless in reading the instructions and did not take into account all the recommendations for use.
2. Wrong place. Ultrasound does not penetrate walls, carpets, thick curtains and furniture.
3. The room is too big. Perhaps the range of the device is less than the area of ​​​​the apartment.
4. Extreme temperatures. A room climate that is too cold or too hot can negatively affect the performance of the repeller.
5. Saving. Budget devices emit low-frequency waves, which pests quickly get used to.

Since cockroaches most often “walk” along the floor, it is recommended to install the device no higher than 1 m above the baseboard. It is important that the device is in an upright position.

Fumigators - cockroach repellers

The operating principle of electrofumigators is based on heating special chemicals and their subsequent evaporation into the air. Evaporation negatively affects the sense of smell of insects. There are a lot of options for carriers of irritating chemicals, since the operation of the devices is based on a single principle.

Inside the device there is a ceramic element with a spiral. During operation, the latter is heated to a temperature sufficient to slowly evaporate the contents of the carrier.

Fumigators that work well against mosquitoes work poorly against cockroaches

Manufacturers of such devices claim that their devices are safe for humans, but the odors emitted when the poisonous plate is heated or the liquid evaporates are quite pungent. Vapors can cause people to feel worse, so being in the same room with a working electric fumigator is extremely undesirable. After turning off the device and ventilating the room, the effect on pests stops.

Despite all the disadvantages, electrofumigators are not without steady demand in the market. This is due to their relative effectiveness and reasonable price.

By the way, much more effective aquafumigators for the most part are not repellents, but work to exterminate pests.

Reviews

Reviews about the use of ultrasonic and electromagnetic repellers have different responses, since much depends on the degree of contamination of the room, correct use and selection of the appropriate device.

I once tried an ultrasonic repeller. Yes, it works, but not for long. When its effectiveness ends, the Prussians appear again. So I decided to carry out chemical treatment together with my neighbors and let’s see what comes of it.

It so happened that the cockroaches themselves disappeared, since we live on an avenue where there are a lot of different communications. They most likely couldn't handle all the noise and we haven't had them for several years.

Kinds

Devices that repel cockroaches are distinguished by their versatility, parameters, properties, operating principle and range.

Ultrasonic

The device does not kill, but repels cockroaches using ultrasound. The waves travel quite far. Only when the frequency is high do cockroaches leave their habitat. Such devices do not have a negative effect on the human body or pets.

Magnetic resonance

The devices emit low-frequency electromagnetic waves. This forces insects to change their place of residence. The safety of a repeller directly depends on its power. Devices emitting low frequencies are unproductive: the devices only repel pests without killing them, but do not harm people and animals. Industrial magnetic resonance repellers are considered more effective, but they have a bad effect on the human body.

Electrofumigators and aquafumigators

Electrofumigators against cockroaches look the same as their anti-mosquito counterparts. To operate the device, special tablets are used, which emit a specific odor when heated. The aroma spreads throughout the room and repels pests.

Aquafumigators are considered a fairly strong and universal remedy. The device is connected to an outlet and a substance is released along with the water that repels and poisons cockroaches. Compared to other devices, the devices are low cost, easy to use, and quite effective. Cons: the substance may have an unpleasant odor and be harmful to health.

Tornado OTAR-2

The manufacturer of the Tornado brand produces many drugs against cockroaches, but the Tornado OTAR-2 model turned out to be more effective.

Characteristics:

• Russian manufacturer.
• Double impact. In addition to sound waves, the device also emits light waves.
• The best place to place the Tornado repeller is to hang the product in the kitchen under the wall cabinets.
• For convenient placement there is a swivel mount.
• Price - 1000-1500 rubles.

Tornado brand repellers have both positive and negative reviews. Many people say that the number of cockroaches has decreased significantly, but over time they come back again.

Universal rodent and insect repellers

Repellers of this kind will help get rid of different types of pests. They are used both in production and at home.
