Mosquito bites are not only unpleasant, but also dangerous. Insects carry many diseases: malaria, yellow fever, tularemia, etc. Now, along with the usual sprays and fumigators, repellents have appeared on the market. These are fairly new devices, the effectiveness of which many users argue about.

Technical description

A mosquito repeller is a device that makes insects feel uncomfortable and forces them to leave a specific location. It does not kill, but only creates unbearable conditions for the existence of insects.

The operation of the device can be based on radiation:

  • ultrasound;
  • poisonous vapors or gases.

Mosquito Repeller

Before use, the repeller is connected to the mains or batteries are inserted into it. Gadgets have a certain range, which depends on their power.

Types of mosquito repellents

Mole Repeller

In accordance with the design features and the mechanism of action, scarers are divided into several types. Each of them is advisable to use in certain conditions.

Ultrasonic Mosquito Repellent

Electronic devices emit acoustic waves of a certain frequency, which coincide with the squeak of a male mosquito. The females cannot stand this sound and fly away. It is they who cause inconvenience to people - they need blood for reproduction.

Ultrasonic Repeller

The average radius of action of the ultrasonic mosquito repeller is 2 m. The device can be either stand-alone or stationary.

Outdoor devices

For outdoor recreation, when people are in one place, scarer lamps have been created. They glow quite brightly, and the repellents they release scare away insects. They do not require an electrical connection and can be installed anywhere.

On a note! There are street ultrasound models, which are small key rings the size of a matchbox. Such a device is easy to take with you for a walk, fishing or a summer cottage.

Stationary models

To work, they must be connected to the mains, so these devices are suitable only for an apartment or a private house. However, with a portable power supply, they can also be used outdoors.

Advantages and disadvantages, features of use

The popularity of various models of repellents is due to their indisputable advantages over similar mosquito control methods:

  • ease of handling;
  • health safety;
  • no negative impact on other household appliances;
  • long period of work;
  • low power consumption.

Ease of use

Dog Repeller

But it was not without its drawbacks. Consumers noted the following disadvantages:

  • high price;
  • the gadget is not always able to scare away insects;
  • after turning off the device, insects quickly return;
  • there is a high probability of buying a fake.

To get the desired effect, you should familiarize yourself with the features of using these devices:

  • Find a suitable location for the ultrasonic repeller. Acoustic waves do not penetrate objects, but are reflected from them. If the space in front of the device is cluttered, there is no need to hope for a positive result.
  • To protect against insects on the street, several devices are simultaneously connected.They are placed around the perimeter of the site to prevent mosquitoes from approaching.
  • Models with several operating modes are suitable for long-term use. Insects acquire resistance to ultrasound over time, so the frequency of acoustic waves is periodically changed.

Important! Before using the device, be sure to read the instructions and familiarize yourself with the operating rules.

Criterias of choice

When deciding which device to buy, you should determine the purpose of its use. For home, stationary models that require a constant connection to the network are suitable, for the street - mobile and compact devices that will not take up much space.

Do-it-yourself mole scarer

You should first study customer reviews. Some devices do not live up to promises made by manufacturers.

Attention! There are many fakes on the market - you need to buy devices only from trusted suppliers who have proven themselves on the positive side.

Diy mosquito repeller

If you have the right skills, you can make a mosquito repeller yourself. The main thing is to understand electronic circuits and be able to use a soldering iron. Parts are sold at amateur radio stores. They are also sold on popular platforms, for example, AliExpress.

The device diagram is shown in the picture.

 

Scheme

The power source is a rechargeable battery or batteries. Diode VD1 protects against incorrect connection. With increasing voltage, the power of the device increases.

The sound is reproduced by a piezoelectric emitter. Resistors determine the operating points of transistors VT1 and VT2. The mechanism of the device is looped. Capacitors are ceramic, designed for a given voltage with a certain margin. The frequency is regulated by resistor R6.

Note! Such a device will scare away mosquitoes and midges within a radius of 1 m. With an increase in power, it will allow to drive away stray dogs. However, experimenting with this indicator is not worth it - problems may begin for a person.

Mosquito repellents are modern and convenient devices that allow you to get rid of annoying bloodsuckers. The main advantage that distinguishes them from ointments and sprays is safety for humans. You can buy such a gadget in a specialized store or make it yourself, saving money.
