Ultrasonic Cockroach Repellers

Ultrasonic cockroach repeller is positioned as a modern, effective, safe tool. It is a small device that works from an electrical network or adapter. The range depends on the power of the device. An electric device generates ultrasound or creates a specific magnetic field. Habitat conditions change, cockroaches feel discomfort, leave the room.

Operating principle

According to the manufacturers, the device against cockroaches acts effectively in any room. Intimidating properties based on physiological characteristics prusakov. Insects are extremely sensitive to electromagnetic waves, ultrasound. Using an electromagnetic repeller creates an unfavorable habitat for insects. They cannot navigate in space, find food, water, they feel constant discomfort. With prolonged exposure to an electrical appliance, insects begin to leave the room.

Ultrasound from cockroaches generates a small device that plugs into an outlet. The electronic device works in several modes, sending ultrasonic waves of different ranges. Such an action of the apparatus prevents addiction in insects, increases efficiency.

On a note!

For a person, a device against cockroaches in an apartment, a house is imperceptible. The human ear does not perceive high frequency ultrasound, so the presence of the device in the room does not appear in any way on health, health.

Benefits described by manufacturers:

• security;
• efficiency;
• large radius of action;
• ease of use;
• availability;
• thriftiness.

Disadvantages noticed by buyers:

• lack of result with prolonged use of the device for repelling;
• noise from powerful appliances that help drive out insects, but affect people's well-being;
• email the device must always be in the socket in the on state;
• the frequency of sound in simple repellers changes manually, which is also inconvenient;
• in the presence of carpets in the apartment, a large amount of furniture, the effect of ultrasound is reduced.

The discrepancies between the declared benefits and the actual situation are significant. Customers assess the latest devices as ineffective, manufacturers insist on the high results of their products.

The effectiveness of repellers against cockroaches

In nature, there are birds, animals that can generate ultrasound. With it, they determine the location of the victim, the enemy, navigate in space. Cockroaches pick up the slightest fluctuations, but it is impossible to say that they are afraid of ultrasound. An abnormal excess of ultrasonic frequencies, which also negatively affect well-being, human health, can drive them out of the room.

The electronic cockroach repeller is a primitive device that generates waves with a frequency of 18-70 kHz. The human ear catches the range of 16-18 kHz. Electronics works unnoticed by people, constantly changing the frequency of the waves. According to the theory, cockroaches should disappear under the action of the emitter, but in practice this does not always happen.In life, insects are more oriented by the sense of smell, so the presence of ultrasonic vibrations does not particularly affect their well-being, ordinary life.

Another type of cockroach remedy to the outlet also generates an additional magnetic field. Manufacturers claim that the insect repeller is much more effective than an ultrasonic device. There is no scientific evidence for this.

On a note!

It is alarming that universal ultrasonic repellers act with the same frequency on cockroaches, mosquitoesflies ratsdogs. There is also a controversial claim that the device is safe for animals. It acts on domestic stray dogs, on well-groomed pets - no!

Before buying read reviews. Cockroaches perceive ultrasound, feel, do not tolerate. Must act. I chose the vaunted Scat-44. Waited for the result for 2 weeks. The Prussians ran, as before. Nothing has changed. In a month there were even more of them. Beginnings poison cockroaches.

Marina, Moscow

Pest Reject worked with us for almost 2 weeks. The manufacturer promises the complete expulsion of the Prussians during this time. There are more cockroaches. Absolutely useless thing.

Elena, Tver

I installed ultrasonic Grad in the apartment. Noisy, but acting. After a week, the continuous buzz of insects became less. After 20 days, they disappeared. The device continued to buzz for another week. Then laid out gel bait to fix the result, they turned off the device. I don’t know by what principle this device works and whether ultrasound helps, but this is the only repeller that works!

Andrey, Voronezh

To increase the efficiency of ultrasonic devices, accelerate the process of eliminating pests, it is recommended to use a modern tool along with effective insecticidal substances - gels, aerosols, sprays. If manufacturers of an ultrasound device indicate this information, you should not buy such a tool. Will act exclusively poison. Before buying a device, read reviews. Some repellers really help.
