6 types of cockroach repellers - is there any point in buying them?

Ultrasound includes waves with a frequency of over 20 thousand hertz. Physically, a person does not hear them, but the body still perceives these vibrations and can react to them. Despite the range beyond their perception, people have long been using ultrasound in various areas of their lives. It is used in medical and biological research, industry, transportation and technical fields. It is used to create cleaning devices for jewelry, medical instruments and household items. The most famous “users” of ultrasound in nature are bats. It is he who helps them accurately navigate in the pitch darkness of the caves.

Dolphins, cetaceans, some birds, rodents and even mosquitoes communicate using ultrasound. Many animals do not use it for communication, but are able to hear it. This explains the effectiveness of ultrasonic pest repellers for home and garden pests. The higher the ability of parasites to perceive sound vibrations of a given range, the more effective such equipment is in combating them.

Such devices include an ultrasonic cockroach repeller, reviews of which are sometimes very contradictory. Why do some admire his work, while others consider it a waste of money? First of all, you need to understand that ultrasound does not kill, but only scares cockroaches, creates uncomfortable conditions for their life, which is why the insects leave the apartment after a while. Unfortunately, ultrasonic devices receive some complaints precisely because of a lack of understanding of the principle of their operation. The second problem is that cockroaches do not respond to the device at all. Most often this concerns recently hatched young animals.

The reason lies in the physiology of cockroaches. Long-term exposure is required for the expected effect. Just like humans, they do not hear these frequencies, but they are able to feel them. In marine terminology there is such a thing as “The Voice of the Sea”. This is infrasound, created by waves and wind in the range of up to 6-10 hertz, which can cause pain in the ears and a strong feeling of fear, even panic. Ultrasound affects cockroaches in much the same way. The third problem that can be encountered when using sound repellers is the impact on households and pets. Fortunately, this influence is selective, but still probable. Decorative rats or guinea pigs will inevitably feel it, cats and dogs - depending on your luck. In the case of people, exposure to ultrasonic radiation can manifest itself as side symptoms, which at first many do not even associate with repellers: headache, irritability, discomfort in the ears, weakness, poor sleep. The manifestation of these and other ailments is very individual and depends on the characteristics of the body. The human body may well not react to ultrasound at all. To avoid direct exposure, turn on the device when there is no one in the room - ultrasound waves do not pass through walls, wooden doors and glass, but are only reflected from them. However, for maximum effect, manufacturers advise keeping the devices turned on at all times.

If you have chosen an ultrasonic repeller, then a reasonable question arises: which one is better to choose?

Types of devices

Several types of devices are presented to the buyer's attention - electronic cockroach repellers, differing in their operating principle. Some of them emit electromagnetic waves, others – high-frequency sound waves.

Ultrasonic

Most often, an ultrasonic cockroach repeller is preferred. The device produces high-frequency sound waves that have a detrimental effect on parasites.

There is no effect of ultrasound on pets (dogs, cats, parrots, etc.) . Man is also not sensitive to sound.

The disadvantages of such a repeller include high cost and unsafety for pregnant women.

Electromagnetic

An electromagnetic cockroach repeller produces a low-frequency electromagnetic field that encourages pests to look for another habitat.

Electromagnetic devices can emit weak waves, then the device cannot be called effective.

But the device is absolutely safe for residents . More powerful equipment cannot be used in the same room with people. This is the unattractiveness of this type of electric repeller.

Advantages of an electronic device

Electronic repellers have a considerable number of advantages, discussed in the list below:

• Safety of exposure for humans, pets, and the environment;
• Easy to use, since to start the device you just need to plug it into a power outlet;
• Lack of chemical exposure and pronounced odor;
• Ease of use and absence of negative side effects;
• Large radius of influence, which completely protects the living space;
• Safety and noiselessness when using the device;
• Low power consumption, so the device can work around the clock, as it does not overheat and cannot be damaged;
• Long service life;
• Possibility of parallel operation in combination with other electrical devices;
• Emitted ultrasonic waves have the ability to be reflected from the surface, which contributes to their uniform distribution over the entire impact area.

An electric repeller quickly gives the desired effect without additional effort and protects the living space from the harmful invasion of various parasites.

How effective is the device?

Many people wonder whether ultrasound helps in persecuting pests as much as device manufacturers claim?

In the process of experimental work, scientists were able to find out that when using ultrasonic devices, the effect is selective. The signal from the equipment is transmitted to representatives of the colony, however, not all, but mostly mature individuals, are among the “informed”.

Residents notice that the young animals will continue to attack for a long time and even crawl on the device itself . There are cases when parasites leave only the room in which the repeller is working.

The low efficiency of ultrasonic cockroach repellers is sometimes the result of improper actions by residents:

• ignoring the points of the annotation attached to the product;
• incorrect choice of place to place the repeller;
• discrepancy between the power of the device and the area being treated;
• purchasing budget models that are not equipped with the option to prevent parasites from becoming accustomed to high-frequency waves.

The principle of operation of repellers: how does the device work on cockroaches?

The device for repelling cockroaches includes a high-frequency pulse generator and a speaker. Does the device really have such a detrimental effect on cockroaches?

If you believe the results of scientific research, the principle is to influence the nervous system of mustachioed pests - the parasites experience discomfort and leave their previous home . Thus, the cockroach repeller does not kill the insect, but only creates an unfavorable environment.

Before you figure out how to install and get rid of cockroaches once and for all, it’s worth taking into account a few recommendations for choosing an ultrasonic device.

Preventing population growth

Buying and installing an ultrasonic cockroach repeller is half the battle. It is also important to slow down and stop reproduction in order to eliminate all pests. As soon as uninvited guests appear on the horizon, they immediately begin to fight them. First of all, they do a general wet cleaning, then they eliminate favorable factors that promote reproduction.

Main places where pests are located

The main areas favorable for insects to live are the kitchen, bathroom, and toilet. They are the ones who deserve close attention. The kitchen is a source of food, water, warmth, where cockroaches often grow and raise offspring. Population growth is especially facilitated by unsanitary conditions: open food, dirty plates, crumbs, leftover food on the floor and tables. What to do:

• Wash dishes regularly, especially at night.
• Store food in airtight packaging, in the refrigerator, or take it to a cold place: cellar, barn, balcony.
• Dispose of waste regularly, and it is especially important not to leave trash out overnight.
• The floor is swept daily, leaving no crumbs or food residues. It is advisable to wash it every day with disinfectant liquids.
• The tap is turned off and the sink is wiped dry to limit individuals’ access to water.

Pipes under the sink, bathtub, toilet in the hygiene room and toilet are a Klondike for uninvited guests. To drive them away, do the following:

• Remove soggy bars of soap, open cosmetics, and personal hygiene products from shelves and soap dishes.
• Wipe the floor dry after bathing or washing, and turn off the taps to prevent water from dripping.
• The rooms are ventilated several times every day to prevent condensation from accumulating on the walls, ceiling, and other surfaces.
• Clean regularly, especially in hard-to-reach places, using disinfectant solutions, powders, and gels.

What promotes the reproduction of individuals

• 1) Favorable temperature conditions
  . Insects live where it is warm: near heating radiators, in ventilation ducts, cracks in baseboards and walls, warm pipes, under wallpaper near radiators, inside household appliances, gas stoves. Having noticed the first unexpected guest, carefully check the ventilation holes and seal them with fine mesh. Seal baseboard cracks, cracks in walls, floors, clean out old pipes, clean out bookshelves, cabinets and drawers.
• 2) Constant access to food
  . A bucket of waste, piles of dirty dishes, food left on the stove - a source of food, especially at dusk. Things scattered around the apartment, shelves, drawers filled with rubbish are a favorable habitat for cockroaches, making it difficult to fight them.
• 3) Sources of water
  . Insects can starve for a long time, but thirst is fatal to them. During a pest invasion, all sources of liquid are blocked as much as possible. They repair broken taps, wipe dry condensation and remaining moisture in the bathroom, kitchen sink, and bowls. Flowers are watered into a flowerpot, not from a tray, and pets' drinking bowls are removed at night.

An ultrasonic insect repeller is an effective but auxiliary product. To completely expel uninvited visitors and stop population growth, regular cleaning and disinfection are necessary.

Tips for choosing a device

To choose a good cockroach repeller, it is worth considering a number of key criteria for evaluating models:

• device dimensions;
• repeller power;
• functional fullness of the model;
• method of powering equipment.

There are devices from foreign and domestic manufacturers on the market. Based on customer reviews, it can be argued that the following models of devices have become the most popular and well-proven:

1. Tsunami. Product from a domestic manufacturer. Powered by mains. The device is compact in size and can operate in an unheated room. When you turn on the equipment, a blue indicator appears on the device body and a ticking sound is heard, which “speaks” of a constantly changing wave frequency. The repeller does not have advanced functionality. Can be used in a room up to 200 m2.
2. Electric cat Turbo. The device is capable of operating in a room up to 400 m2. The domestic repeller operates from the network and in autonomous mode changes the frequency of ultrasonic oscillations. In this case, both light and sound influence the pests. The device can be turned on during the day and at night.
3. Hail. In the ranking of the best repellers, this device is the most powerful - it is capable of expelling cockroaches from a room of up to 1000 m2. The equipment can be used not only in the room, but also outdoors - the effectiveness of the Grad does not change when conditions change. The equipment is powered from the mains, battery, cigarette lighter. The power indicator of the device can be adjusted . The model has advanced functionality and is capable of operating in the following modes: silent, influence on mosquitoes, repels rodents, exterminate small pests (can scare off cockroaches, ants, beetles).
4. Pest Reject. American device model. Equipment is used on an area of ​​no more than 200 m2. Judging by customer reviews, the device is considered one of the most effective, fast and reliable. The model can be used in the fight against cockroaches, moths, ants, and mosquitoes. The repeller is even more effective when traps are used together.
5. Clean house. Model from a Russian manufacturer. Can be used in rooms up to 150 m2. The repeller emits ultrasonic waves all the time without changing their frequency. The functionality of the device has not been expanded. Among the shortcomings of the equipment, it is important to emphasize the impossibility of using the device in a room without heating.
6. Typhoon. The country of origin of the device is Russia. The model is made in the shape of a square, it affects pests all the time by changing the frequency of ultrasonic radiation. Reviews about the device are satisfactory - after 1-2 weeks the parasites partially disappear.
7. Ultrasonic duet. A favorite among competitors. The device operates in three modes, differing in ultrasound frequency. The range is about 550 m2. The first effect from using the device can be noticed after 2-3 days.

Review of the most popular plug-in devices for cockroaches

The modern market for appropriate electrical devices against pests remains practically overflowing with all kinds of offers. Many of them do not deserve attention at all, however, there are a number of worthy devices that can be used to repel pests.

These include:

1. Pest Reject. This generator is not the most powerful or very efficient. However, we must give credit to the manufacturers. In addition to praising their own product, they very tactfully make the disclaimer that it demonstrates better performance when combined with a variety of sticky traps. Therefore it is better to use them together. With this combination it is really possible to overcome the problem of cockroach infestation.
2. Typhoon LS-500. A domestic development that remains not very popular due to its relatively low efficiency. In certain cases, there is a slight decrease in the number of Prussians encountered, however, such a result is not enough.
3. WK-600. One of the industrial repellers. It is a large and heavy (600 g) unit that generates high-frequency ultrasonic waves. Due to its large area of ​​​​action, it is often used in warehouses and workshops, where there is a need to prevent the penetration of “uninvited guests”. Nevertheless, this device can be successfully used at home. According to reviews from most users, the WK-600 really works. But its price is also appropriate - 4000 rubles. Not everyone can afford such pleasure for fighting insects.
4. Zenet XJ-90. Representative of not very successful models. It extremely rarely demonstrates any results, and then they are often associated with the parallel use of other methods of exterminating pests.
5. Banzai LS927. A Taiwanese product that actually has the stated effect on insects. It effectively repels pests and frees the apartment from them. However, its impact also extends to the individual and his family. This device is not recommended to be left turned on for a long time, which significantly reduces its demand.
6. Eco-Sniper AR-120. Another representative of conditionally effective devices. It demonstrates average results and does not always justify its cost of 800-900 rubles.

As you can see, there are quite a lot of options for various devices against cockroaches. Sometimes you can even get confused, because every manufacturer says that their device is the best.

Despite all this, you need to understand that such ultrasonic and electromagnetic generators are more of an auxiliary tool than the main way to combat insects. Therefore, sometimes it is easier to use the good old insecticidal aerosol than to spend money on expensive and not always effective electrical appliances. And if cockroaches are not too annoying, you can turn to folk remedies and repellent odors.

It’s easy to find reviews about Pest Reject on the Internet, including on YouTube:

Safety and effectiveness

An ultrasonic cockroach repeller most often works from the mains; to turn it on, you just need to plug the plug into the outlet. Some models have buttons to press before starting work.

Before using the device, you must read the manufacturer's instructions. Following the recommendations presented in the annotation will ensure not only the safety, but also the effectiveness of the device. So,

• the distance from the floor to the device should be within 1 m, the device should be open on all sides: if there are objects in the path of the ultrasound, the effect of using the repeller will decrease;
• Damaged or disassembled devices should not be used;
• it is necessary to prevent impacts on the repeller and liquid getting into the equipment;
• It is recommended to observe the temperature regime: the device should not get too hot or cold;
• To achieve maximum effect, you should use several devices at once, placed in different rooms of the apartment or house.

General recommendations

Of course, you can trust the opinions of others, you can try a device to repel pests in your home, in any case, the fight must be waged immediately. Indeed, in addition to disgust and nausea, cockroaches can provoke allergic reactions, they are carriers of bacteria and are also incredibly fertile. Therefore, observe the rules of hygiene as much as possible. Do not leave open food on the table or other places accessible to insects. Don't accumulate trash and rubbish. Clean your apartment more often, paying attention to ventilation holes and other secluded places - favorite corners of cockroach colonies.

FAQ

In conclusion, it is worth answering a number of the most frequently asked questions within the topic.

Is the repeller harmful to household members (adults, children, pets)?

The ultrasonic repeller targets only cockroaches (or other parasites); the ears of people and pets are not susceptible to the emitted sound.

Are cockroaches really afraid of ultrasound?

High-frequency sound waves affect the nervous system of pests - the parasites experience discomfort and run away, but do not die.

Is it possible to be in the same room with a working repeller?

The safety of a device depends on its power. Some models exclude the fact that people are in the same room with the device turned on. To avoid negative consequences, before using the device, you should read the instructions from the manufacturer.

An ultrasonic cockroach repeller is a truly effective and, in some cases, absolutely safe means of pest control.

However, often due to the low awareness of buyers on this pressing issue, households tend to give preference to alternative methods (most often chemicals).
