Electronic pest control devices have been claimed by manufacturers to be very effective. Previous buyers have written testimonies that it truly worked.

How do Electronic Pest Control Devices Work?

There are two main types of electronic pest control devices: ultrasonic and electromagnetic. Ultrasonic pest control devices emit short wavelengths, high frequency sound waves which could repel away pests in a range of diameter. On the other hand, electromagnetic devices alter the electromagnetic field keeping away pest in a particular area.

Electronic pest control devices are said to be safe for humans. The human ear can only hear frequencies between 20 Hz – 20 KHz while ultrasonic devices emit sound waves at higher frequencies. For an instance, grasshoppers and locusts can only detect frequencies from 50 kHz – 100 kHz.

Are They Really Effective?

The effect and methodology of these devices may sound very appealing to so far, there’s not enough proof to substantiate these claims. There isn’t enough scientific evidence to show that these products work consistently for all types of pests.

Actual Effects of Electronic Pest Control Devices on Pests

Many researchers tested the effect of these devices to different kinds of pests. For the most part, it can’t repel pests. It doesn’t change their performance or kill them. However, a study shown that, ultrasonic devices have somehow affected the reproduction of Indianmeal moth. When an Indianmeal moth was subjected to a 94 dB sound wave, it produces less sperm, fewer larva, and weightless larva.

Cockroaches on the other hand, are completely unaffected by ultrasonic devices. There’s proof that cockroaches can hear the sounds but they completely ignore it after being exposed to it for a few seconds. It is also ineffective against rodents like rats, squirrels, raccoons, etc.


Not only is the level of efficacy of these products exaggerated, they have no scientific evidence to prove these products even have some effect. The only things they have are the testimonies given by people which may be fabricated. Even if some of these testimonials are true, studies have shown that the results are inconsistent. The good results may only be circumstantial and the results could be manipulated. Traditional pest control and organic pest control, despite being less expensive, have been proven time and time again to be more effective in killing and controlling pests.

For now, electronic pest control devices need a bit more work to become more effective. What’s great about them is if these products do work, we can eliminate the use of harmful chemical in pest control. But for now, it’s best to use traditional methods until manufacturer make these products as effective as they claim to be.
