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.
What sounds will repel mosquitoes?
Many studies have been conducted to determine what frequency of sound is needed to repel mosquitoes. But all of them not only failed to identify the necessary values, but also cast doubt on all arguments that ultrasound can help in the fight against insects. The minimum value is 4 kHz, but even this may not apply equally to different fauna.
Employees of one radio station also suggested using ultrasound against mosquitoes. In addition to the musical composition, they included ultrasound. Most adults' hearing aids couldn't pick it up, but the bloodsuckers had to stay away. Music against mosquitoes was supposed to give residents the opportunity to relax quietly in nature or do gardening without annoying midges.
Mosquito repellent sounds
Interesting!
The world-famous home appliance company LG has released a whole series of air conditioners that contain a device for repelling mosquitoes using ultrasound.
The opinion that mosquitoes are afraid of ultrasound has often been used for selfish purposes by many entrepreneurs. Some offered mobile phone users to download a special ringtone, the range of which was supposed to scare away bloodsuckers.
Some developers offered to purchase devices that imitate the sounds of a dragonfly. It is these insects that are one of the worst enemies of bloodsuckers. A dragonfly can eat an almost unlimited number of mosquitoes, which is why they will try to avoid it. But it has been scientifically proven that the sound of dragonfly wings is in the range of 20-170 Hz, which is significantly lower than what the device suggests.
The development of Soviet scientists was especially popular. This is a special multivibrator equipped with a frequency selection function. Thus, users could set a mosquito-killing sound depending on their region of residence.
Interesting!
Mosquitoes have many natural enemies, and some developers have decided to use the croaking sound of frogs to recreate a frightening sound.
Thus, scientists could not find one hundred percent confirmation that buzzing, beeping, croaking or any other sound at any frequency can help fight mosquitoes. It turned out to be even more difficult to find the very range of required sound vibrations. Therefore, to combat bloodsuckers, it is better to use proven and effective mosquito repellents.
Tips for choosing the right model
The market is full of different types of repellers. Practice shows that not all proposed models cope with their task. Highly effective repellers are more expensive and get rid of pests. And dubious, low-cost ones cannot even repel mosquitoes, let alone cockroaches. In this regard, it is worth following certain tips when choosing the right model:
- If the residents of a house or apartment purchase an expensive and undoubtedly powerful device, then it is unsafe to stay at home during its operation (about 4 weeks). The best solution would be to move out of the living area.
- There are devices whose action extends to no more than a square meter. Such devices are best used in rooms where people do not live, or on the street. It is allowed to place several repellers in one room, which operate at a distance of up to fifty square meters.
- It is necessary to carefully select the type of food. If you go on a trip or are outdoors, then it is better to use a battery-powered repeller. At home, it is recommended to use the mains power method.
- To avoid accidentally stumbling upon a fake, it is best to buy the device in specialized and trusted stores.
- When purchasing, you should pay attention to the range of the repeller. The device is not able to influence parasites through obstacles (furniture, walls, carpets).
Review of ultrasonic outdoor repellers
Sometimes when traveling to nature or to the country, it becomes necessary to use various means to eliminate blood-sucking insects. Probably many people know how many of these creatures fly outside in the summer, especially in places near water bodies. In this case, an outdoor mosquito repeller will come in handy. Typically these devices are powered by special batteries.
Popular outdoor repellers include the following models:
- Weitech WK0029. This device is made in Belgium. It has a compact size, so you can easily take it with you on the road. The device body is convenient for installation in a tent or outdoors. This is an electronic device. It is possible to adjust the intensity of ultrasonic radiation.
- Protector Freetime. This is a universal device. It can be used at home, for the street, or simply attach a mosquito repeller to your belt. Thanks to its compact size, you can take it with you to the countryside or to the countryside. The area of distribution outdoors is up to 1.5 meters, indoors up to 30 meters.
- Mosquito repeller Cosmos. This device has low power. The radius of wave propagation is only 3-5 meters, no more. It produces a floating sound wave. Can work in three time modes - 4,4 and 8 hours. When working, it imitates the buzzing of a dragonfly.
How to properly install and use electronic repellers
The effectiveness of a repeller directly depends on the ability to place and use it correctly. To do this, there are some rules that must be followed:
- It is advisable to use several repellers at the same time. This will certainly help get rid of a large number of parasites. One device is allowed in each room.
- In order for the device to cover a larger area, it should be placed at a height of 1 m and only in a vertical position.
- Due to obstacles in the room, the effectiveness of the ultrasonic repeller is reduced. The solution to this problem is to place multiple devices in the room.
- After installing the device, be sure to monitor the condition of people nearby. If the action of the device negatively affects them, then it is better to refrain from using it and choose another method of combating parasites.
- If the equipment has any damage or does not work correctly, it should be sent for repair. It is not permitted to use a damaged device.
- Along with the repeller, it is also possible to use other methods to get rid of cockroaches.
- Experts believe that ultrasound does not give instant results. Ideally, the repeller should work for about a month.
- The device must not be disconnected from the network even for a short time, otherwise the cockroaches will return.
- After installing the device, you need to monitor its temperature. Avoid overheating or excessive cooling.
Does ultrasound against mosquitoes help in the fight against insects? :
Probably everyone has encountered the annoying buzzing of insects and mosquito bites. If you can protect yourself at home with the help of fumigators and plates, then in nature it is more difficult to do this.
Sprays, lotions, and spirals contain chemicals that are undesirable for use in areas where there are children or pregnant women. In principle, they are not so harmless for everyone. Recently, they have begun to actively offer ultrasound against mosquitoes.
How does ultrasound work?
Ultrasound against mosquitoes works quite simply - it releases waves of a certain frequency that humans cannot hear. But insects actively react to them.
Human eardrums have a complex structure, so they do not vibrate as actively as those of mosquitoes, bats, and flies.
The latter catch frequencies using not only their ears, but also their antennae, villi on their paws, and genitals.
Ultrasound for mosquitoes does not kill insects, it only repels them, driving them to a safe distance. This device was known 30 years ago, but began to be actively used only now.
Advertising videos and posters can be found on the Internet. Reviews vary: some claim that there is no better means of protection, while others take the position that ultrasound is absolutely useless. Such devices cost from 1000 to 5000 rubles.
It all depends on what type of device you will purchase.
What does the insect hear?
Many people ask why ultrasound is effective against mosquitoes? What sounds cause insects to fly to a safe distance? To answer this question, you need to know the following facts. Scientists have proven that only female mosquitoes bite people, and this happens immediately after mating with a male and fertilization.
How effective are repellers?
There is still no consensus on what the results of using cockroach repellents are. Some people think that the product does not cope well with its intended purpose and negatively affects the health of its owners, while others admire its work and believe that it really helps.
The fight against parasites has been ongoing for a long time. Chemicals and toxic substances are used, but this is an extremely unsafe method. An electric repeller is easy to use, hassle-free and less dangerous. The devices produce sound at a high frequency from 18 kHz. Animals and people are not able to perceive such a frequency, but harmful insects are susceptible to its influence. Fumigators drive away cockroaches best if sound waves of different frequencies are used.
What attracts cockroaches to the house
Cockroaches require comfortable conditions and food. Unfortunately, you, without knowing it, can give them everything they need for nutrition and reproduction. If you left food on the kitchen table overnight, didn’t take it out on time, or didn’t wash out the trash can - hello, mustachioed brethren. Fortunately, cockroaches settle in the same places where they feed. This means that you can remove the entire colony easily and quickly.
The appearance of cockroaches in the house indicates that you are not careful enough about cleanliness.
The choice of weapons in the fight against cockroaches is extremely large - traps, glue, paste, gel, crayons, pencils. Recently, ultrasonic repellers have become more and more famous. How do they work and is it really a miracle against the cockroach army?
Reasons for the ineffectiveness of the device against cockroaches
Scientists conducted various experiments and found out how insects communicate - through ultrasonic signals. Most often, mosquitoes communicate in this way. Cockroaches are less sensitive to this type of repeller. The study showed that adult individuals do indeed leave their habitat when exposed to ultrasound, but this does not frighten juveniles so much. However, it cannot be said that the repeller is completely ineffective. The unproductivity of the device may be due to several reasons:
- The equipment is incorrectly selected. Before purchasing, carefully study the area of the apartment or house. Based on this information, a repeller suitable for the living space is selected.
- The device is not installed correctly. Ultrasound does not pass through walls and other obstacles. Also, sound frequencies are reflected from a hard surface and absorbed by soft objects.
- We saved on quality and purchased a cheap repeller from an unknown brand that does not inspire any trust.
- Inattention. If the battery is low, the device stops sending ultrasound and becomes completely useless.
The cockroach repeller gives good results if you follow the manufacturer's instructions and advice. A high-quality repeller can be purchased from 900 to 7,000 rubles. Talk to specialists if you have any difficulties making your choice.
Ultrasound against mosquitoes
In their life activities, blood-sucking creatures are guided by a keen sense of smell and ultrasound. Insects detect infrared rays, the smell of carbon dioxide, lactic acid, and sweat. They are able to determine the location of a potential victim from a distance of several tens of meters.
The sound from mosquitoes, according to manufacturers, is of a certain frequency. The human ear cannot detect it, but insects hear well. What frequency it should be, studies were carried out, as a result of which a value of 4 kHz - 6 kHz was revealed.
On a note!
Manufacturers claim that the mosquito-repellent sound imitates the flight of a dragonfly. However, the predator, by flapping its wings, creates ultrasound at a frequency of 20 kHz, which contradicts the information indicated on the device. If mosquitoes heard the approach of a dragonfly so clearly, they would not become victims of a predator and would have time to move to a safe distance.
Advantages and disadvantages of electronic repellers
