Ultrasonic rodent repeller is a relatively new product for rodent control. For many, it has already become an excellent alternative to other methods of control involving the killing of animals - the use of traps and poisons. Also want to humanely get rid of rodents? Unpleasant the very idea of poisoning or trapping them and the subsequent fiddling with dead carcasses?
All these questions are solved by an ultrasonic rodent repeller. In this article, we will tell you how rats feel and behave when exposed to ultrasound, how to choose the right repeller for any room size, what you need to know about ultrasound and how to use the device correctly.
We'll also find out: Are these devices safe for cats, dogs and hamsters?
What you need to know about the action of ultrasonic repellents
Ultrasonic mouse repellers can be used safely in any environment: apartments, houses, food warehouses, offices, retail spaces, industrial premises, hospitals, etc.
Most electronic repellers emit only ultrasound - usually budget, low-power models for small spaces. More expensive models can also affect pests with electromagnetic radiation, sound and flashes of light. And, although it is possible to eliminate rodents with ultrasound alone, a combination of methods of exposure will give the best result, especially for large rooms.
Ultrasound cannot penetrate walls and floors, so a separate device is required for each room.
Ultrasound reflects well from a hard surface (wood, concrete, glass) and is just as well absorbed by soft surfaces such as curtains, upholstered furniture, carpets, food bags. Therefore, it is best to turn on the rat repeller in as empty a room as possible - this will work best.
How to choose a rodent repellent device for small, medium and large rooms?
Choose an ultrasonic rodent repeller based on your needs and the recommendations of those who used this item. But what else should you consider and what to look for when choosing a pest repeller?
- Carefully read the characteristics of the repeller regarding ultrasound: the range of radiated high frequencies (if it captures frequencies up to 20 kHz, then you will hear it), constant change (by default or the ability to select a mode) of the frequency of the emitted wave, the angle of propagation of the signal ( the bigger, the better).
- Consider the characteristics of the room. For example, if food is stored in a room, then rodents cannot be quickly expelled from there. An ultrasonic rodent repeller can fight them for about two months. For comparison, in the absence of food and water, the rodents will leave in about two weeks.
- Remember about pets. If you have pets at home, be aware that repellers are safe and will not harm animals or their hearing. But in cats, dogs, and other pets such as hamsters and guinea pigs, ultrasound can cause anxiety. they have better hearing than humans and they can hear it. Keep this in mind and remove pets from the premises where such a device works.
- Keep in mind that repellers of different power and types of impact are needed for rooms with different areas. Therefore, pay attention to the declared coverage area of the device and measure it with yours. But remember that the packaging indicates the area of the empty space, respectively, evaluate the degree of workload with furniture and things in your apartment, house or office. Remember that repellers work best in empty and semi-empty spaces!
Rodent repellents: 6 most popular questions
How do rats feel and behave when exposed to ultrasound?
When you just turn on the device, rats can become perplexed by new unpleasant sounds, hide in their hiding places, or, on the contrary, start chaotic running around the room in an attempt to hide from the source of uncomfortable sounds. It is in this case that it may seem to you that the repeller does not work, but only attracts pests - but it is not! It's just that the rats are in a state of shock and don't know what to do. Fortunately, in most modern instruments, the frequencies "pulse", changing every few minutes by 2-10 kHz. This prevents rodents from getting used to the unpleasant effects and makes ultrasound from mice very effective.
Ultrasound causes panic, anxiety, confusion, and a sense of extreme discomfort in rodents - especially if the device is constantly running. But at the same time, they are not so stupid as to just take and leave the warm housing they have lived in. Therefore, they can wait for several days in the hope that this nightmare will end. When this does not come, they are forced to flee. This process usually takes about 2 weeks on average.
Why does ultrasound have such an effect on rodents, but a person does not hear it?
The thing is that humans and rodents have different ranges of sound waves that they can perceive by ear. In humans, it is approximately equal to 20 Hz-16 kHz, and in mice from 200 Hz to 76 kHz. Ultrasound, on the other hand, is called waves with a frequency higher than 20 kHz, which a person, unlike rodents, is no longer able to hear due to the limitations of the hearing aid.
The most popular devices have a built-in function of constantly changing the frequency of the wave so that rats do not have time to get used to unpleasant sounds. And here it all depends on the range of the emitted waves of each specific device. Its upper limits usually do not raise questions, but the lower limit of the range (in different cases it is 5 kHz, 18 kHz, etc.) can be heard by people as well.
How many rodent repellents do you need to clean your home?
The answer depends on the number of rooms and the scale of the infection. Ideally, there should be one ultrasonic rodent repeller per room. ultrasound cannot penetrate walls. When it comes to home, also consider the basement and attic and other areas that may be especially attractive to rats (kitchen, pantry, and other areas where food is stored).
The electronic mouse and rat repeller does not work: what could be the problem?
Perhaps the room is too cluttered and it is worth taking out unnecessary things that interfere with the operation of the ultrasonic device. The repeller works best in a space with a minimum of soft things that absorb ultrasound: upholstered furniture, carpets, curtains, fabrics, toys. In such a room, ultrasound from rats is able to fill the space due to multiple reflections from hard surfaces, walls, ceilings and floors.
If you're trying to get rid of rodents in grocery stores, food is a double problem. Firstly, rats will never refuse to eat for nothing, and secondly, bags with bulk products (for example, grain) perfectly absorb ultrasound. Above all, take out food that attracts rodents. Many biologists say that rats can endure pain for food, and then they just get used to ultrasound and learn to ignore it.
Also, according to scientists, in some cases, electronic rodent repellents may simply not work, so, including the repeller, do not wait too long. Optimal period: 2-3 weeks - if during this time the rats have not disappeared, turn off the device and use traps or rat poisons.
How to understand that it is time to unplug the repeller?
In accordance with the opinion of the manufacturers, we recommend that you do not remove the device from the socket until the rats have completely disappeared (this should take 2-3 weeks). Sometimes people complain that the rodent control device worked at first, and then suddenly stopped, and the rats reappeared. This may be due precisely to the fact that it was not turned off in time! Theoretically, if another rat family immediately replaces the old rodents, they can immediately get used to the constant exposure to ultrasound.
Remember: the ultrasonic rat repeller does not protect the house from the invasion of rodents, it only helps to escort the existing ones!
Which is better: ultrasonic repeller, rat poison or trap?
All methods are good in their own way, but you shouldn't use them at the same time! This is a common mistake of all frightened homeowners who, when they see rats in the house, immediately rush to acquire all possible means at once. But traps, poisons, as well as poison for rats and mice, and repellents simply cannot work together - they have opposite actions: the first remedies lure rodents, and repellents repel them.
It is advisable to first use a humane method of scaring away, and in the future, if necessary, scatter the poison or set up traps. So you will know that you did everything you could, and, most importantly, you did everything right!
