Ultrasonic Pest Repellers And Control

You might think this is a novel invention, but it is not. In reality, humans have been fighting to deter pests throughout history. Unfortunately, most of these insects and animals became common because of the poor hygiene practices we used to have.

Way before the 15th century, civilizations used different techniques to keep pests out of crops. Ancient Greek, Chinese and Sumerian societies used sounds and fire to keep small animals away from the fields. They understood these animals affected the quality of the products.

Fast forward to the 1940s; we find modern insecticides such as DDT and other synthetic insect repellents. But later on, experts found out exposure to these chemical compounds was related to cancer.

There is not much information about the exact origin of ultrasonic pest repellers. However, we know commercial repellers originated somewhere between 1960 and 1965. In addition, sound experts have been exploring sonic and ultrasonic reactions in small animals as early as 1900.

The first generation of ultrasonic pest repellers was advertised as a solution to keep rats and mice out of your house. But, some specialists analyzed the pros and cons of these devices. Some investigations concluded ultrasonic devices were ineffective.

How They Work

Any sound over 18,000 Hz is considered ultrasonic. The human ear is not fitted for hearing these frequencies. However, it has been proven that some animals can.

These ultrasonic sounds can cause distress in animals. Some tests included rats, dogs, rabbits. They concluded animals could even die out of exposure to ultrasonic sounds.

Most commercial ultrasonic repellers work with a power source. You either connect them to an electric outlet or add batteries to it. Once you turn it on, it will start emitting ultrasonic waves that deter rats, mosquitoes, and many other bugs.

The Drawbacks About Ultrasonic Pest Repellers

The main drawback here is that ultrasonic repellers don’t always work. Many people who have one at home seem to be satisfied with it. Some users and experts claim it is a hoax.

Some of the arguments experts have against ultrasonic repellers include:

  1. Ultrasonic waves don’t efficiently travel through objects. This means that your furniture, clothes, and any other solid object in your home will decrease its effectiveness on pests.
  2. Some pests can grow resistant to ultrasonic sounds. The initial tests were done in a controlled environment. However, further investigation revealed that rodents got used to these waves.

Even if these claims are not correct, ultrasonic repellers have disadvantages for some members of your household. Think about your pets; most domestic animals can hear these sounds. While some pets might not be bothered by it, ultrasonic sounds can harm small animals such as guinea pigs and rabbits.
