Traditionally, various means are used to combat home pests (rodents). Among them, traditional mousetres and cappos, a variety of bait and poisons, but often these efforts are vain. Relatively recently used new high-tech development - ultrasound repellers for rodents. This remedy can help for a long time to get rid of the unprofitable neighborhood of rats and mice, as well as underground rodents (earthling and moles), while its impact is safe for people.
Principle of Ultrasonic Scaretcher
The most malicious pests in everyday life, garden and garden, as well as in basements and cellars, warehouses, the trauma traditionally are mice and rats. They, as well as other rodents spoil food, as well as wiring, distribute some dangerous diseases. The use of electronic devices for scaring rodents is convenient, efficiently and economically justified, as it allows to save efforts and means for the preparation of poisons, poisoned bait and cappos for pests.
The relatively new and secure method of scaring small pests is the use of ultrasound. In devices for scaring rodents, the detected intolerance to the ultrasound rodents (high frequency sounds - over 20 kHz) are successfully applied. This impact is similar to the influence of the hum of the hum of the reactive aircraft. With all this, the method is quite humane - ultrasound does not kill animals, and scares, causing fear and anxiety from them, makes it comes to escape. On the first day of the application, the rodent device goes to sound, begin to run circles, after which they fall into a stupor of irritant and unbearable sound, and then try to leave the zone of its impact.
With the help of laboratory research, it was revealed that in the presence of a continuous impact of ultrasonic frequencies, rats feel the growing sense of inconvenience and after a while (usually for three days to several weeks) leave the room irradiated with ultrasound. It is known that mice and rats are the first two weeks from the birth of the deaf - thus ultrasound raises its impact on them over time (it may be necessary for about a month). To achieve the maximum effect, it is recommended to continuously use ultrasound impacts during the first three weeks. It should be noted that for the prevention, the device can work without time limit, i.e. constantly.
Modern electronic repellers in the process of radiation constantly change the parameters of the generated ultrasonic waves - frequency and intensity, as a result of which the effect of an irritant, disorienting, as well as the overwhelming effect on rats and mice is achieved, and addictive is excluded. The use of ultrasonic rodent discreteners is effective in gardening and garden areas, as well as in various premises - in the conditions of urban apartments, country houses and cottages, warehouses, offices, granaries, livestock complexes, various enterprises.
Advantages of rodent frightening devices
The advantages of ultrasonic rodent repellents are:
- the use of these devices in different environments - in homes and deserted places;
- ease of use;
- economy of use;
- stable operation under various temperature regimes - in the range from -25 to +30 ° C;
- no harmful effects on the operation of the device on humans and most animals.
Features of the application of ultrasonic repeller
When placing the ultrasonic treatment device, consider the following:
- for large structures manufacturers recommend the use of repellents in each isolated compartment, in residential buildings - one device, respectively, on the flat, floor, basement, attic. The apartment repeller is placed in the kitchen or in the bathroom, ie in places where the mouse penetrate through the riser, through the ventilation shaft;
- in warehouses, bags filled with products and porous material absorbing ultrasonic waves, regardless of the floor area is recommended to use several repellents placed in the gaps between the racks. To eliminate the interaction of the devices to be installed at a distance of not less than 5 m from each other;
- in the construction of the device may be capable of switching the ultrasonic repeller in various modes of operation (with is in the room and people without their presence).
In addition, there are some features of the application of ultrasonic repeller:
- ultrasound propagates in the air like light rays - that It does not pass through walls, windows, ceilings, and floors and ceilings. Thus, efficient use of ultrasonic devices for repelling pests within a room;
- ultrasonic waves propagate differently in different environments. Hard surfaces (wood, concrete, glass) well reflect ultrasound, soft absorb it. If the room there is no furniture, carpet, curtains, then there is multiple reflection of ultrasound from the walls, ceiling and floor - in such circumstances the use of repeller effectively;
- most electronic rodent repellents produce ultrasound, but some can emit electromagnetic waves;
- to exclude rodents exposed to ultrasonic addictive, design repeller devices provide the ability to switch manually using the knob, or automatically change the frequency parameters.
Selection of ultrasound discharge
The sale presents a fairly wide selection of ultrasonic frightening devices for rodents. In order to buy an effective rodent repeller, pre-analyze outgoing data for the application of the device - the size of the object that is required to be protected from pests, as well as the planned mode of use of the device. On the Internet you can find various recommendations and reviews on ultrasound dischargers. Cheap devices are sold with a guarantee for just a few months, while they differ in low power and low frequency range. More qualitative devices are accompanied by a warranty for 12 months - to obtain a real result, do not try to buy a repeller as cheaper as possible, choose the models of proven manufacturers.
For example, Tornado rodent repellers successfully work both above the ground and underground, are convenient for accommodation anywhere, the radius of these devices is within 200-800 m.
Tsunami rjuckers are distinguished by compact sizes and low cost (effective exposure area is somewhat lower than that of a tornado). According to customer reviews, these devices are fighting qualitatively with the presence of a variety of rodents, while not needing maintenance.
The jets of rodents of Grad have proven well in the market. In these devices, the maximum ultrasound power is reached, available for safe radiation in the presence of people.
For the expulsion of pests (small rodents and insects) in the design of repeated rodent repellers, a highly efficient combination of ultrasonic and electromagnetic radiation is used, while the device is absolutely safe for a person - according to the manufacturer's assurances, it can be absolutely able to apply it in the children's room using 24 hours a day on throughout the year.
Restrictions on the operation of ultrasonic frightening devices rodents
There are some requirements that need to be observed during the operation of the repeller:
- it is necessary to apply a device in a room with normal humidity, as well as to eliminate the impact of aggressive chemicals;
- do not allow mechanical effects on the device body, directly emitter and power cord;
- operation of the repeller when the case lid removed, the presence of mechanical damage to the cord and the structural elements of the device is prohibited;
- it is recommended to install the device in the distance from heat sources, do not allow it in the rain, as well as direct solar rays.
Many are interested in the question to what extent is the use of ultrasound devices for a person. Specialists are responsible as follows - the physiological features of a person make it possible to not perceive the oscillations of over 22 kHz. In devices for scaring rodents, ultrasound frequencies are used in the range of 35-65 kHz. The experimental way was established that with the sound of the sound 130 dB of this frequency and the condition that the device generating the sound is located at a distance of a half-meter - in the presence of a long exposure, a person may feel ringing in the ears, as well as feel the headache. With increasing distance from the device up to 1 m and more negative effects, it was not detected.
Thus, there are some restrictions on the use of ultrasonic repellers for rodents - it is not recommended that the application of the device in the presence of children under 8 years of age is not recommended, as well as at the close distance in the direction of human finding - for a long time.
