All about fly and midge repellents

With the arrival of heat, flies, midges and other flying insects are activated. To combat them, special ultrasonic devices are used.

The Fly Repeller forces insects to leave the area within the radius it affects. The exterminator, on the other hand, attracts small pests by sucking them into a vacuum container.

The frequency of the ultrasound is such that the flying bloodsuckers cannot harm the people in the building. Such devices are bought into the house to protect it from mosquitoes. This is an effective way to combat harmful insects.

The key point in such cases is the place of operation of the device. If you need to get rid of blood-sucking insects in the house, abandon exterminators and give preference to repellents. The former requires a lot of space to work correctly, they synthesize gas that can be dangerous to people.

Scare devices have an impressive list of advantages:

• compact size;
• silent work;
• indoor safety.

The scarers are compact and generate high-frequency waves. Such devices operate from a network or a battery. When insects get within the range of the device, they sense the danger.

Ultrasound is a natural, natural signal. It causes fear in representatives of living beings.

The principle of operation of such devices is as follows:

1. when activated, the repeller emits a sound alert;
2. the signal covers the room;
3. an insect within the range of the device feels vibrations;
4. to avoid flies getting used to the frequency spectrum, it changes all the time.

The modification and class of the device determine the range of its action.

The stores offer a large selection of ultrasonic devices for mosquitoes and flies. They are usually classified into two main categories:

1. stationary;
2. portable.

Mosquito and fly repellents differ not only in the range of action, but also in the frequency of sound. Please read the instruction manual carefully before purchasing. Devices intended for warehouses must not be used in apartments - it is dangerous to health.

Portable models are harmless to humans. Their feature and at the same time a minus is a small radius of action. Such devices are used for personal protection, protection of premises.

Portable devices operate from finger or rechargeable batteries. When choosing a device, focus on its work. If the range is less than 1 meter, the device will be ineffective in protecting the premises. Portable models can be used not only at home, but also outdoors.

Stationary ones operate from the mains at a voltage of 220 V. In a number of modifications, batteries are used. Devices from this series are installed in warehouses, apartments, industrial workshops.

Repellers work at a great distance and can kill flies and other insects in a few minutes.Before buying a sound device, we advise you to consult a seller. Do not use high-power electronic devices in apartments and country houses.

We list the best models of electrical insect repellent devices.

The device acts on flying bloodsuckers using ultrasound. It can be used both outdoors and indoors. It operates at a frequency of 4-40 kHz. The radius of action is 50 sq.m. The device works not only from the mains, but also from AA batteries.

Its advantages include:

• reasonable price;
• the presence of batteries in the package;
• versatility (can be used indoors and outdoors).

The disadvantages include noise during operation and poor build quality. This is a budget ultrasonic device capable of protecting its owner from blood-sucking insects, excluding their presence on an area of ​​50 sq. M. With such a device, you can comfortably spend time outdoors and in a country house.

Ultrasonic repeller, which is used in an enclosed space. The device operates from the electrical network, has a coverage area of ​​50 sq. M. It has a night light, 3 built-in modes of operation. The advantages of this model include the ability to change regimes, democratic cost.

Ultrasonic repelling device with an effective coverage area of ​​20 sq. M. Replaceable cartridges serve as a power source. The device has several modes of operation. The basic package includes replaceable plates. This is a street model that does not make noise when running.

Its disadvantages include the impossibility of using it in closed rooms. Replacement cartridges have to be bought on order.

Manufacturers offer devices for outdoor and indoor use. Most buyers prefer versatile models that are suitable for both buildings and open spaces. A device that drives away midges can be bought for a summer residence and for a city apartment.

When choosing, focus on the type of exposure - ultrasound is considered optimal. The recommended radius of action is 30 sq.m. It is best to buy devices with universal power supply, operating both from the mains and from the battery.

Ideally, the battery life should be about 1 month. A high-quality emitter should have a minimum number of obstructions (thin grating or large slots on the body) in the area of ​​the sound wave emitter. It should function in a shift mode, activating and deactivating at regular intervals.

In order to have a clear idea of ​​what technical parameters a repelling device should have, carefully study the list of devices that are included in the list of the best effectively repelling blood-sucking insects.

Ultrasound has a detrimental effect on mosquitoes and other harmful insects. It is recommended to use devices that generate air vibrations at home. To activate, the device must be plugged into the mains. There are battery operated models. They are all easy to use. Before activating one of these devices, read the instructions, be sure to take into account the operating conditions declared by the manufacturer (indoors, outdoors, or here and there).
