Cockroaches are the most unwanted neighbors in the house. They cause a lot of trouble, are carriers of infectious diseases. Dealing with parasites requires effort and an integrated approach. To get rid of cockroaches, many owners of apartments and houses opt not for chemicals, but for repellents. These are devices that act on insects using ultrasound.

Types of cockroach repellents

The choice of a device in the fight against insects must be made taking into account the area of ​​the room. If there is no way to connect the device to an electric power supply in the room, you need to choose a scarer that runs on batteries.

There are several types of devices:

  • Ultrasonic - a device that emits ultrasound that affects the nervous system of insects. High-frequency waves are inaudible to a person, but they are very unpleasant for a cockroach and will help scare him away. They begin to feel a sense of danger and leave the premises. One device can cover a large room of up to 80 m².
  • Electronic. This device works on the principle of a fumigator. The device has a tablet slot. The repeller is powered by an outlet. As the temperature rises, the tablet or liquid begins to smell. This type has both advantages and disadvantages. The smell emitted from the device is unpleasant for humans. The device stops functioning as soon as it is disconnected from the wall outlet. Plus, you have to constantly change the records.
  • Electromagnetic. A good effect in the fight against insects can be achieved using an electromagnetic repeller. It is connected to the network, then all the wiring begins to emit waves. Their effect is directed not only to cockroaches, but also to rats, mice, bedbugs. One device is sufficient for 150 m². The device is safe for humans and does not interfere with the operation of electrical devices.
  • Sound. There are combined types of devices that act with ultrasound and emit electromagnetic radiation.

Note! When choosing a device, you need to pay attention not only to the area of ​​the room, but also to the possibility of connection, the degree of infection with parasites.

Features of the device, characteristics and rules of use

The principle of operation of the device depends on its type. The most commonly used devices are those that operate from an outlet. If there is a fight against cockroaches in an apartment, the electronic repeller plugs into the outlet and, depending on its variety, starts working. When it comes to an ultrasonic device, it emits waves of a certain range. They change their frequency regularly.

The insects do not die, but the sound signal that the device emits makes them leave. At the same time, ultrasound is not felt by people, does not cause inconvenience.

Important! Do not use ultrasonic devices in rooms where a pregnant woman lives. The fruit is very sensitive to waves, it can be harmful!

Electrofumigators function in the same way as mosquito repellents. They will require a tablet or liquid bottle to work. When connected to the power supply, the device starts to heat up, and the liquid or tablet gives off an odor. He is also unable to kill cockroaches, but will force them to leave the apartment. The disadvantage of this type is the smell in the room.

The rating of cockroach repellents is based on customer reviews. The most efficient devices include:

  • Typhoon LS-500 is considered one of the best ultrasonic cockroach repellents. Its peculiarity is that the intensity of the waves is constantly changing. This makes it impossible for the parasites to adapt with it. For the device to work as efficiently as possible, you need to open all windows and doors.
  • The device from cockroaches - the electronic Rexant repeller - is an effective device that helps to get rid of not only insects, but also mice and rats. The radius of action is 60 m.
  • Pest Rejekt is a safe device that operates on a 220 V network. Its coverage area is 200 m². The backlight is built into the body of the device. In the dark, it acts as a night light. The ultrasound will help repel insects. He does not destroy them completely, but forces them to leave the premises.
  • Riddex is a device designed to repel insects and rodents. It works absolutely silently, does not harm pets and people. The device covers an impact area of ​​up to 80 m². The operation of the device is based on a combination of ultrasound with electromagnetic radiation, which negatively affects the nervous system of insects. Cockroaches constantly feel discomfort, lose their appetite, and stop multiplying.

Important! Any kind of device can only be used indoors. The repeller will not work if it is connected in the open air. When using, it is important to avoid sudden changes in temperature and high humidity.

The appliance must be kept plugged in for the entire period until the insects disappear completely. At the very beginning, their activity can be observed. Sometimes it seems that their number has increased, but this is a temporary phenomenon. Cockroaches start to fuss, so it seems like there are too many of them. But after 2-3 weeks, the insects will go away.

The ultrasonic cockroach repeller is effective for controlling insects, but its disadvantage is its high cost. If you have knowledge of the work of radio components, the device can be made at home by yourself. This will require a diagram and spare parts. Most often they are taken from old tape recorders, players and radios.

Resistors from R1 to R5 are needed to regulate the current and voltage in the network. To manufacture the device, you will also need a toggle switch and a piezo emitter. Any manufacturer will do. In this case, the toggle switch will be used to turn on the device.

In addition, you need:

  • transistors T1 and T2 and capacitors C1 and C2, which create a frequency circuit;
  • diode for protection against incorrect connection;
  • blanks for radio amateurs to create a board;
  • variable resistor that will provide power regulation.
