Cockroaches are not only disgusting, but also dangerous. These harmful insects carry dysentery, Escherichia coli, worm larvae and even subcutaneous ticks. They can cause typhoid, tuberculosis and other serious illnesses. Today we will tell you how to get rid of cockroaches without chemical attack, and help you choose a quality insect repeller.

Principle of operation

Cockroach repeller is a device that helps get rid of insects with the help of ultrasound, aromatic substances or electromagnetic waves. The device is connected to an autonomous power source or a stationary network and forms an aggressive environment for cockroaches and other pests. Ultrasound (or electromagnetic waves, depending on the device) affects the nervous system of the insect, forcing it to leave its habitat. It is worth remembering that the repeller is not able to completely destroy the pests, so it is better to use it in combination with other means.

Cockroach repeller

Kinds

There are 4 types of repellers - sound, electromagnetic, aqua and electric fumigant. They differ from each other by the principle of work and overall efficiency. We discuss each of the types in more detail:

Ultrasonic

Such devices emit high-frequency sound waves that repel insects. However, they do not affect dogs, cats, parrots and other pets. The human ear for ultrasound is immune, because he is not able to catch high frequencies in the range from 20 kHz to 1 GHz. The radius of the device is large enough and covers several rooms at once.

Benefits:

  • simple design and management;
  • can be in the room at the time of operation of the device;
  • safe for people and pets.

Disadvantages:

  • unproven effectiveness;
  • high price;
  • not suitable for pregnant women.

Magnetic resonance

A magnetic resonance type device emits low-frequency electromagnetic waves, forcing cockroaches to leave their habitat. According to manufacturers, the security of these repellers depends on the power. Devices that generate weak waves are considered ineffective in pest control, but they do not pose a threat to residents. There is also a magnetic resonance industrial repeller, which is much better at its task, but is not suitable for use in the presence of people.

Benefits:

  • wide choice in different price segments;
  • safety of use;
  • large range of radiation.

Disadvantages:

  • effectiveness is in question.

Electrofumigators and aquafumigators

Electrofumigators work in the same way as conventional devices with mosquito repellent plates. You just need to plug the device into a power outlet and insert a special tablet into the compartment with the heating element. Aromatic substances begin to spread around the room, deterring insects.

Aquafumigators work on a similar principle, but the excreted substance enters the air with evaporating water. This is a fairly powerful device that can not only scare off a cockroach, but also poison it. However, despite its effectiveness, such devices can be dangerous for people due to the toxins used.

Benefits:

  • effective work;
  • low cost (compared to other devices);
  • Ease of controls.

Disadvantages:

  • odors;
  • used substances can harm health;
  • separately buy plates and fluids.

If you are looking for the safest way to repel cockroaches, you should pay attention to ultrasonic and electromagnetic devices.Fumigators are much more effective, but they use chemicals that can cause dizziness, allergic reactions, etc. As for the price, devices with interchangeable plates and fluids are cheaper, but for them you need to buy consumables. If cockroaches appear in your house periodically (for example, a certain time of the year), it is more profitable to purchase an expensive reusable machine without consumables. It will pay off after several years of use.

How to choose

When choosing a repeller, you should pay attention to the radius and duration of action. Most often, these indicators are indicated in the technical characteristics of the device. Ultrasound can not penetrate walls or other obstacles, so in a multi-room apartment you may need several devices at once.

Duration of work depends on the type of food. There are stand-alone battery powered devices. They are perfect for a summer cottage or village. Stationary repellers work from the network. They are easier to use at home.
