What Is a Pest Repeller And Where Is It Applied?

This is an electronic device that serves to make pests flee from your territory. The vast majority of gadgets are plug-in models (they are installed in rooms), though some models can work on your backyard, or be portable to ensure protection during outdoor activities. How does it work? Ultrasound attracts pests, later they find it annoying and irritating, which makes them leave the territory. In 3-4 weeks, such sound damages their nervous system.

  • Ultrasonic

Ultrasonic repellers emit low-frequency sound waves that only pests can hear (insects and rodents). Humans and house pets like cats and dogs cannot hear ultrasonic waves. Such device is totally harmless for them.

  • Electromagnetic

Electromagnetic models work in the same manner, though they are considered to be more advanced. An electromagnetic unit intensifies the signal, which ensures even better protection. Electromagnetic waves can go through obstacles like walls and furniture. Some rodents and pests are sensitive to the abnormal electromagnetic field, which may force them to leave your house.

How To Select The Best Ultrasonic Pest Repeller?

In fact, there’s not so much you should consider as the vast majority of repellers work in the same manner. These three factors below are crucial.

  • Price

Pretty often, vendor offer 2, 4, or 6-pack of repellers, which is way more cost-efficient than buying them separately. Ideally, you need to place 1-2 repeller in each room, so buying packs helps to save money. Don’t forget that the price depends on the quality of the device.

  • Coverage Area

Most often, one repeller covers the area of 1,200-1,600 square feet. Ultrasound waves do not penetrate walls and furniture, so one repeller protects a single room. Calculate the floor space of your house/apartments to make the right choice.

  • Safety

The vast majority of repellers are 100% safe for adults and kids, cats and dogs. Please, note that such pets as hamsters, mice, and rats are susceptible to this sound. Do not use a repeller if you have one. Some repellers are created to prevent the invasion of cats, dogs, squirrels, and other larger animals. The sounds they emit can be heard by humans, so they should be installed far from the house.

  1. Ultrasound waves emitted by repellers do not penetrate walls or furniture, so one unit protects one room.
  2. A repeller isn’t equally effective against all insects: ants and spiders can get used to the sound realizing it is harmless.
  3. As for rodents, their activity stops in about 6 days after repellers had been activated: it’s a highly efficient measure against rats and mice.
  4. Ultrasound is the sound frequencies beyond the upper limit of human hearing, that’s why we are not aware of waves emitted by repellers.
  5. Humans do not experience any ultrasonic pest repeller side effects because they simply cannot percept the sound.
