Ultrasonic Pest Control Units – Do They Work??

Ultrasonic pest control units advertise that they can help repel mice and rats. Plus, some people find that they also keep away spiders, ant and roaches too.

Does Ultrasonic Pest Control Really Work?

However, these devices almost seem too good to be true. I mean, you just buy a $25 gadget, plug it into your wall and you’re done with all of your rodent problems? No traps, poisons or even effort? Hmm…

It may not be so simple. So, I went ahead and tried them for myself.

What I Discovered About Ultrasonic Pest Control Devices:

1. Choose a Reputable Brand

First of all, I found plenty of these ultrasonic pest repellent gadgets under many different brand names. Many of which I’ve never even heard of.

Bell and Howell Ultrasonic Pest Control with Electromagnetic Technology and Extra Plug OutletYou can’t really tell the intensity or power of the waves between the various units. Therefore, I went with a well-known brand name, Bell and Howell. They’ve been around over 100 years.

2. Get Ultrasonic + Electromagnetic Units

Second, I decided to boost my “repelling power” by getting a device that included both ultrasonic and electromagnetic technology.

From my understanding, the ultrasonic waves bounce off hard surfaces within the room and don’t travel through walls, while electromagnetic energy uses the wiring to radiate behind and within the walls. Essentially, electromagnetic wave pulse through the home via the electric circuits.

Therefore, if you get an ultrasonic-only device, you need to place one in every room. On the other hand, you can use a single ultrasonic + electromagnetic repellent for every 1,000 feet.

Not only can you cover more area within your home, you don’t have to buy as many units to keep mice away. Bonus!

3. Look for Non-Repetitive Waves

Third, I got a device that featured non-repetitive waves. This way, animals don’t get used to the sound over time. Some cheaper products don’t mention whether they emitted repetitive waves or not, so I just assumed they might be and didn’t buy them.

4. Use Enough Units

From other customer reviews I read, I noticed that people who only purchased a single device didn’t seem to get rid of their mice. This makes sense, since you want to cover your entire home, not just part of it.

5. Don’t Block the Waves

As I mentioned above, hard surfaces reflect ultrasound waves while softer surfaces absorb it. For this reason, you don’t want to place a unit behind a sofa because the sound waves will be absorbed.

Therefore, I plugged in each unit on an open wall where there was no furniture. In addition, I placed them in the larger rooms in my house.

6. Place Them Lower on Walls

Sixth, I located the units close to the floor. I read that some people heard clicking sounds from the units every time the LED indicator blinked. From my experience, the sound is barely audible, especially when plugged into a wall outlet near the floor.

7. Choose the Version with Side Outlet (if You Want)

Seventh, I opted for the product version that included a side outlet. This way, I don’t lose a plug space. This feature does cost more, so if you don’t mind giving up a plug space, go for the cheaper version.

Answers to Frequently Asked Questions
About Ultrasonic Pest Control:

1. How Do Ultrasonic Waves Work to Repel Pests?

Each device puts out high sound frequencies that bounce off hard surfaces and create intense auditory stress for rodents. This discourages them from building nests in the area, so they go elsewhere. The units start repelling immediately once plugged in.

2. How Long Do Pest Repellers Last?

Devices usually last between 3-5 years. Some last longer. As long as the LED indicator light is blinking, the unit still works.

Ultrasonic Waves Don't Bother Cats and Dogs

3. Do Ultrasonic Waves Bother Pets?

These devices don’t bother cats or dogs. However, it can affect rodent pets like rats, hamsters or guinea pigs. So, if you have rodent-type pets, these electronic units are not the best option.

4. How Much to They Cost to Operate?

According to the Biocontrol Network, ultrasonic pest control units typically cost about 20-30 cents per month (less than a penny a day).

5. Do They Inhibit or Interrupt Other Electronic Devices?

Units do not interfere with pacemakers, garage door openers or any other electronic equipment.

William D Fitzwater wrote a report titled, “Electromagnetic Repellers – Fact or Fiction?” which was then published by the University of Nebraska. It included 16 different tests and studies done on electromagnetic rodent repellents and their effects.

They concluded that “There appears to exist a scientific basis for the belief that electromagnetic forces can change behavioral patterns of mammals. However, experimental support data are based on animals confined in higher intensity fields that seem possible with field units.”

The report also states that measuring the exact magnetic force put out by these devices proves to be difficult. In addition, it’s hard to distinguish the effectiveness of products made by different manufacturers.

Victor Pest recommends using ultrasonic pest control units in combination with other methods. For example, secure access points into your home and remove any attractants like pet food. In addition, using traps or baits can help maximize your efforts…
