Are Electronic Pest Control & Repellent Devices a Waste of Money?

Electronic Pest Control Repellent Devices, High-Frequency Pest Control Do Not Work!

Explained – Why High-Frequency Pest Control Does Not Work!

There are plenty of clever high-tech gadgets on the market – from vacuum robots to smart homes. One thing that does not make the list are electronic pest control devices. These devices claim that the ultrasonic high frequency acts as a repellent against pests. Unfortunately, one of our clients recently learnt that the hundreds of dollars spent on these devices were a waste of time and money.

If you are looking at electronic pest control devices, put them back on the shelf and save yourself the inconvenience.

Electronic Pest Control Devices – How They (Are Supposed To) Work

High-frequency pest repellents are small units that you plug into a power outlet. Units need to be installed all over the house – and according to our clients, cost around $100 each! (*1). Once plugged in and the power turned on, they emit a very high frequency that humans cannot hear(*2).

They are supposed to (at the very least) repel cockroaches, spiders, ants, rodents, and other pests (depending on the device). Some devices also claim that the high frequency will kill the pest. To kill the pest, the high frequency must cause the rodent or insect to suffer a cerebral haemorrhage(*2).

Unfortunately, our clients have not had any success at deterring pests, let alone eliminating them using these devices. A scientific study found that the only insect that was deterred was the humble cricket(*3).

The Limits of High-Frequency Pest Control Devices

In our homes, many signals are going on that can interfere with each other. Furthermore, not all signals can travel through walls and furniture. Electronic pest control devices are no different. If the pest is not in the direct line of the frequency, they will not notice it(*2,3). Furthermore, once they realise it (the sound) is not life-threatening, they get used to hearing it and begin to ignore it(*2).

Your Pets and High-Frequency Sounds

If you have a cat or dog, they will also be able to hear the high frequency emitted by the device. According to the dog experts at Wag(*4), electronic pest repellents do not usually bother dogs unless they are particularly nervous or sensitive. Other common pets such as birds, have a similar hearing range to humans so cannot hear the frequency. Always be sure to talk to your veterinarian about your pets before considering a high-frequency device.
