To date, many different means are known that can scare away insects. But not all chemicals are an acceptable method of control, as they emit an unpleasant odor and release elements harmful to health. That is why an ultrasonic bug repeller is often used, which belongs to environmentally friendly devices.

Types of scarers

On the modern market, you can find 3 main types of bug repellents:

  • combined;
  • ultrasonic;
  • electromagnetic.

Ultrasonic scarers

Devices of this type have the ability to scare away bedbugs due to exposure to high-frequency sound waves, which insects cannot withstand for a long time. The disadvantage of an ultrasonic repeller is that its effect applies only to adults, but the eggs remain in the same place. Therefore, after 10 days, the procedure must be repeated, and possibly more than once.

Electromagnetic scarers

Electromagnetic scarers also cause insects to leave the premises. This is due to the fact that the adaptation directly affects the nervous system of the parasites. Thanks to this, they begin to lose orientation in space. In addition, their activity decreases and a feeling of fear comes to them, which prompts them to escape from the source of radiation of electromagnetic waves.

The principle of operation of the device is that it generates low-frequency electromagnetic waves, which begin to affect the bugs 2-3 days after switching on. It is important that electromagnetic radiation is capable of covering all rooms in which the wiring passes and even get into the most inaccessible places in the home.

Note! The radiation of electromagnetic waves does not affect a person, therefore it is absolutely safe.

The electromagnetic bug repeller can be used in various areas: offices, hospitals, farms, living quarters.

In addition to bedbugs, such a device can affect other pests, for example, cockroaches. Insects feel the unpleasant effect of the device and leave the room.

Combined repellents

Combined repellents

These devices have the properties of electromagnetic and ultrasonic scarers, so the effect of the combined device will be stronger and faster. From the moment it is turned on, the device begins to generate magnetic and ultrasonic waves alternately, which does not allow the parasites to get used to the operation of this device.

The principle of operation of the combined repeller is to generate low-frequency electromagnetic waves on the one hand and high-frequency ultrasonic pulses on the other. The operation of the device has a strong effect on the nervous system of bedbugs, insects feel panic and fear, so soon they begin to leave the room.

Important! The electronic repeller does not emit poisonous and chemical substances, therefore it is completely safe for pets and humans. It is also absolutely impossible for the device to affect the operation of household appliances.

Bedbugs are inconspicuous insects, it is very difficult to get rid of them, because, having satiated once, they can do without food for several weeks and feel good at the same time. Parasites are able to adapt well to many modern poisonous substances, so the war against them can continue indefinitely. These pests are not interested in food that other possible inhabitants of the house may like, such as cockroaches or ants. Bedbugs are only interested in blood.

The principle of operation of the ultrasonic repeller is as follows:

  1. Ultrasonic radiation creates conditions unbearable for insects.
  2. The peculiarity of the action lies in the fact that in the process of work, high-frequency waves are created.
  3. The effect of the device is enhanced due to the fact that in the process of radiation, the frequency range changes, which does not allow pests to adapt to the effect of the repeller.

Features of the ultrasonic repeller

In the process of using the ultrasonic device, you must adhere to the following instructions:

  • Ultrasound does not have the ability to pass through walls, so all interior doors must be left open for the duration of the device. You can also install one device in each room.
  • Do not direct the repeller towards carpets or other soft objects in the room, as such materials have the ability to absorb radiation. Failure to comply with this condition will lead to a decrease in the effectiveness of the device.

An ultrasonic type bed bug repeller is an affordable device for any consumer, and this is undoubtedly its great advantage. But it is worth noting a number of positive characteristics of the device:

  • high efficiency, allowing you to get to any impassable and most inaccessible places;
  • no need to find a habitat for parasites;
  • absolute safety for the human body and pets;
  • lack of a sharp and unpleasant odor, which is characteristic of insecticidal agents;
  • ease of use.

Note! Compared to other modern traps for insects, in which the corpses of bugs, flies, ants, etc., accumulate, when using an ultrasonic repeller, there is no need for contact, even visual, with pests, since they leave the house on their own.

How to choose the right scarer

Tornado Ultrasonic Mouse Repeller

In order not to be disappointed in the choice of the device and to protect yourself from additional investment, you need to pay attention to the following factors:

  • sound - a full-fledged high quality device works absolutely silently;
  • permissible temperature regime for the device - this concerns the need to purchase a device for removing bedbugs in office, basement and attic rooms;
  • radius of action;
  • cost - a high-quality device will not have a too low price.

There are many ultrasonic devices on the market today. Sometimes it is not easy to choose something specific. List of the most common models:

  • EMR-21 - produced in Bulgaria and powered by mains.
  • Typhoon LS-500 is a Russian-made repeller. Equipped with automatic frequency switch.
  • Tornado Shock FP-003 - emits not only ultrasonic, but also electromagnetic waves.
  • Ecosniper ls 919 - characterized by the highest degree of coverage, equipped with a frequency switch.
  • Pest Reject insect and rodent repeller - emits ultrasonic and electromagnetic radiation.

Each device has certain characteristics and degree of efficiency.

Do-it-yourself scarers

It is easier to purchase a ready-made device, which will come complete with instructions for use and various warranty agreements. But some craftsmen express a desire to independently invent the device.

In order to make a repeller with your own hands, you need to find a manufacturing scheme for the type of an asymmetrical multivibrator. Preparation of the following items will be required:

  • 2 transistors;
  • 3 resistors;
  • capacitor;
  • battery "Krona";
  • switch;
  • piezo emitter.

For a person who understands electrical circuits, assembling the device is not difficult.

Note! The radius of the homemade device will be no more than 1.5 m. Its dimensions will be compact.

Contraindications

Ultrasonic bug repellers will not harm humans and pets. But there are cases when the operation of the device led to the appearance of headaches, lack of sleep, nervous overstrain and increased human fatigue. Therefore, it is recommended not to turn on the device during the rest period.

Ultrasonic repellents are able to scare away not only bedbugs, but also many other insects that appear in the room. Such an impact negatively affects the pests, they are poorly oriented in space and cannot find a food source (human blood). Therefore, soon they have to leave a place with unfavorable conditions for existence.
