Description of the device

The compact device is manufactured in Russia under the “Clean House” brand by JSC TPK Technoexport. Product weight - 120 g, size W*H (cm) - 15*10.

The ultrasonic pressure that the device exerts on rodents is 100 dB. The frequency is in the range of 20-45 kHz. This is enough to affect mice and rats at the same time.

The spreading angle is 140-160 degrees. The acoustic coverage area is 150 sq.m. The room should not have partitions so that the distribution of waves is uniform.

The repeller operates from a 220V electrical network and consumes 8 W. During continuous operation for 7 days, the device consumes 1.3 kW of electricity. For effective operation, it is left in working condition for 2-3 weeks.

The temperature range for using the device is from 0 to +40 C.

Operating principle

Ultrasonic rat and mouse repellers “Clean House” generate waves that constantly change frequency (in the range of 20-45 kHz). Speed ​​- about 70 changes per second.

Work algorithm:

• The membranes of the device create vibrations that are not audible to the human ear. They act on rodents with the force of the sound of a hammer drill.
• Sound waves travel within the communication range of mice. The transfer of information between them is disrupted.
• A number of frequencies fall on the wave of the alarm signal used by pests. They perceive them as a call to leave their habitats.
• The repeller causes nervous system disorders that lead to refusal of food and prevent reproduction.

Constant discomfort drives rodents out of the premises where the “Clean House” repellent device is installed.

Advantages and disadvantages

Exposure to ultrasound causes mice to retreat to safe areas.

Advantages:

• Safety of use. Waves do not have a negative impact on human health.
• Ease of use. To operate, you only need an outlet connected to the mains.
• Economical. Energy consumption no more than 8 watts.
• Can be used continuously for 2-3 weeks.
• Compact sizes.
• The repeller can be turned on in residential and administrative buildings, public places. Approved for use in catering premises, hospitals, warehouses.
• Waves are reflected from solid surfaces and fill free space.
• A humane way to fight. Animals do not suffer painful deaths. They save life by simply leaving the area exposed to sound frequencies.
• Rodents do not die. No need to remove carcasses. There is no smell of decomposition from individuals that died in inaccessible places.
• Almost silent operation. The absence of annoying sound will not cause discomfort to people who are near the repeller.
• The price of the device in stores ranges from 600 to 1100 rubles.

The device is non-contact and safe, which makes it popular in the fight against rodents.

Important! At the beginning of using the device, disoriented animals go out into open areas. They lose their sense of fear and become aggressive.

Flaws:

• Waves do not penetrate walls. Soft interior items (furniture, curtains, carpets) absorb sounds.
• The strength of the radiation decreases as it moves away from the device.
• The effectiveness of work does not appear instantly. It will take about 7 days to expel rodents.
• Once the repeller is turned off, rats and mice may return.

Rodents can adapt to ultrasound. In this case, the effect of the device is reduced or stopped altogether.

Generator circuit for repelling rodents

The electrical circuit of the generator includes an ultrasonic vibration generator (C3, C4, DD1.3, DD1.4, R3, R4), a low frequency modulator (C1, C4, DD1.4, R1, R2), a power amplifier using transistors VT1- VT3, emitter, which uses a high-frequency loudspeaker 4GDV-1. The generator emits frequency-modulated oscillations in the range of 15....40 kHz

The frequency can be adjusted by resistor R4, the modulation frequency is adjusted by resistor R2 within 2...10 Hz. If you set contact SB1 in such a way that in case of unauthorized entry into the room this contact closes, the generator can work like a security alarm siren, since it begins to emit frequency modulation in the range of 1000...2000 Hz. It is important that when working for a long time in one frequency range, rats get used to it, so you need to change the radiation parameters with resistors R2-R4 2-3 times a week. Or connect capacitor C4 to a piece of wire that creates an additional capacitance that changes with changes in temperature and humidity

Then the frequency will change randomly.

Installation and use of a repeller against mice and rats

The Clean House ultrasound device does not require complex preparation before use.

Installation:

• the repeller is mounted at a height of 0.2-0.8 m from the floor;
• connects to a 220V outlet;
• The power button on the device is activated.

If the installation was completed without errors, the indicator lights up.

Rules of application:

• The area around the device is cleared of interior items that absorb sounds.
• The distance should be at least 2-3 meters.
• The installation height affects the wave coverage and sound pressure. The recommended distance is 20 cm from the floor. This height allows ultrasound to be evenly distributed throughout the treatment area.
• The repeller must operate continuously for 2-3 weeks to expel all pests.
• If the room is divided by partitions, the device is installed in each room, regardless of the area (hard surfaces do not transmit sound).

The device is designed for 150 sq. m. Rooms with a larger area or with a high load of items are equipped with additional devices to increase work efficiency.

Signs of low-quality devices

A little about the technical characteristics reflecting the capabilities of such devices. Unfortunately, in the instructions they are most often overestimated. At the same time, the fact that certain characteristics are reflected already indicates that manufacturers are making attempts to take a responsible approach to their products. This is somewhat better than simply indicating the battery life.

When choosing a repeller, in order not to run into a fake, experts advise focusing on the following points:

• choose a device based on ultrasound;
• the range of sound perception for rodents should be in the range of 80–120 dB;
• wide level of frequency fluctuations and a radiation pattern close to 360 degrees;
• the area of ​​the protected zone indicated in the passport data of the device must be larger than the one that is planned to be processed;
• versatility declared by the manufacturer - please note that one device cannot simultaneously cope with rats, mice, cockroaches, mosquitoes, ants and other insects.
• do not purchase devices that produce sounds audible to humans, since this is clearly not ultrasound.

Safety for humans and pets

The device must be used according to the instructions. The range of sound waves of the device is higher than the level of human perception. They are not harmful to health.

But a sound inaudible to the human ear (from 20 Hz) can sometimes have a negative impact on well-being. Radiation causes headaches. People with increased sensitivity to air vibrations are affected. Therefore, the device should be turned on in residential areas for a short time (especially in bedrooms).

Pets (dogs, cats) do not perceive sound frequencies, just like humans. The waves are safe for farm animals and birds. Repellers can be installed in places where they are kept.

The “Clean House” device will have a negative impact on domestic rodents (hamsters, chinchillas, guinea pigs and other members of the family). They are removed from the rooms in which the device is installed and turned on.

How to make it yourself

Some craftsmen suggest saving on the purchase of a factory device and making a repeller to combat various rodents from scrap materials. You will need a battery and a speaker from an old speaker. The larger the room area, the more powerful both devices should be.

Despite the authors’ assurances of the effectiveness and safety of the homemade rat repeller, there is no need to risk people’s health. Devices manufactured in factory workshops meet certain standards, are tested for safety, and the frequency of ultrasonic waves is recorded in the technical passport. It’s hard to say how a “homemade” device will behave, whether it will be not only effective, but also harmless.

Doctors do not recommend using devices that have not passed mandatory certification. Incorrectly selected frequency of sound waves often provokes various diseases and negatively affects the nervous system.

Other products from the “Clean Home” series

produces a line of mice repellents “Clean House”. It includes not only ultrasonic devices, but also glue mousetraps and poison baits.

Glue

The product, created on the basis of polymers, is non-toxic (there is no poison in the composition). The principle of operation is to hold the individual on the surface with glue. The animal cannot escape and dies from exhaustion.

How to use:

• Glue is applied to a surface that rodents cannot carry away (a sheet of plywood, a wooden board).
• The trap is installed in places where pests appear.
• Once a week you need to change the location. The squeak of an individual caught in a trap will scare away the rest of the family.

For mice, an adhesive area measuring 1*1 dm with a distance between stripes of 2-4 cm will be sufficient. To catch a rat, the substance is applied to an area of ​​at least 2*5 dm, with a stripe width of 5 cm and intervals of 5-10 cm.

To increase efficiency, bait is placed in the center of the trap.

Note! The glue mousetrap needs to be renewed every 10-14 days. Gradually, its effect decreases due to debris and dust that settle on the surface of the product.

Grain bait

The poisonous substance used in the bait is bromadiolone. The poison has an anticoagulant effect. Animals die from internal bleeding.

How to use:

• Poisonous grain is poured into containers and placed at the entrance to burrows or in the path of rodents.
• As consumption progresses, bait is added.

The poison begins to work in the individual’s body after 5-7 days. The drug acts on mice and rats with equal effectiveness.

The poison belongs to hazard class 4. When working with it, you need to take precautions and place containers in places that are inaccessible to other animals and children.

When is ultrasound best for repelling rodents?

One can understand the mistrust of those who are just looking at the Clean House mouse repeller, since reviews from real buyers are not always positive; you can also find very negative ones. However, if you wish, you can also describe the negative experience of using a mousetrap or poison, because everything depends on the conditions of application and compliance with the most important rules. Let's take a closer look at the circumstances that will definitely cause the entire population of mice and rats to quickly leave your territory:

1. Space without barriers. During propagation, the ultrasonic wave is reflected from any solid barriers. It could be a wall, a cabinet, a metal kettle or a chair, but in any case, ultrasound will not penetrate through them, but will be reflected back. Because of this, the best repellency is achieved in spacious rooms where there is not a lot of furniture. Also, through reflection, ultrasound will enter the neighboring room, if only the doors there are open.

2. Lack of sound-absorbing materials. Any object that has a soft and rough surface serves as a strong absorber for ultrasound. This could be a pillow, a carpet, or high-quality soundproofing of the room. Under any circumstances, such objects will reduce the area of ​​effect of the ultrasound, because because of them it will actually become less loud. Since we need to remove rodents from the living room, we recommend removing the largest things with a soft surface from there at least during the first weeks of repelling them.

Why are rodents in the countryside and in agriculture so harmful?

Many summer residents are faced with the problem of the spread of rodents. The harm they cause is obvious. If rodents are in your area, your plants will most likely suffer. You may be at risk of them eating the fruit. They are not only harmful to plants: a rat can also scare your animals. Needless to say, something or other equipment can be damaged by rodents.

These animals not only devour cultivated crops, but also spread diseases that are dangerous to humans. It is known that from these uninvited guests you can catch yersiniosis, salmonellosis, and rabies; rats can transmit tapeworms and even spread fever.

Vasily Rumyantsev, who holds a responsible position in a company that produces products to combat these pests, spoke about the dangers of rodents for agriculture: “They eat not only crops, but also food for animals and birds.” Therefore, it is important to try to prevent them from entering your territory.
