About Ultrasonic Pest Reject

HighYa Staff Published on: Nov 3, 2017

Claiming to be the number one rated pest-repelling device in America, the Ultrasonic Pest Reject claims to use low-frequency sound waves to drive away a variety of insects and rodents in your home, including ants, mosquitos, spiders, mice, and roaches.

The device plugs directly into a wall socket, and its creators state that only one unit per average-sized room is needed. They go on to mention that larger areas such as attics, basements, garages, and large storage areas may require additional devices to work properly.

The primary claim behind the Ultrasonic Pest Reject is that these low-frequency sound waves drive out pests without killing them, negating the need for messy cleanups in the process.

The company behind the product states that it was developed by a Stanford scientist using military technology as a cheaper, non-toxic alternative to conventional pest control methods.

This all sounds admittedly like a great way to keep your home clear and free from unwanted pests, to be sure, but is it really what you can expect when using the device in practice? In order to answer this question directly, we’ll need to zoom in and take a closer look at the technology underpinning it.

Are Sound Waves Really Capable of Keeping Pests Away?

As we mentioned above, the Ultrasonic Pest Reject relies on low-frequency sound waves that are beyond the hearing capabilities of humans in order to deter pests. They claim that these frequencies displace critters while leaving your pets and human counterparts unaffected, but is there any research to back this claim up?

Interestingly, this kind of sonic deterrent has been around for quite a while, and as a result, there’s actually a fair bit of clinical evidence surrounding the technology. Though some trials have been promising in limited areas, the results have largely been mixed.

For instance, in terms of rodents, one clinical trial found that though a sonic device was initially able to upset the creatures, they soon became used to the sound, eventually ignoring it outright.

Another study found that cockroaches who had never been exposed to the sound waves were largely unaffected by them when using three different products (none of which were the Ultrasonic Pest Reject).

Finally, a third study illustrated that ants and spiders were left completely unaffected by similar devices, except in a few rare instances. However, they go on to note that these cases of effectiveness might have been due to design limitations of the trial itself, as opposed to the real-world conditions you’d be more likely to encounter in your home.

So, what does all of this mean for you in the end? Based on the sources linked above, the evidence is clear: the devices don’t seem to be very effective at deterring most of the insects and pests listed by the makers of the product at hand.

In an interview with Buzzfeed, Texas A&M University entomologist Dr. Roger Gold (who has spent the better part of 20 years studying the effectiveness of sonic bug repellants) had this to say about the matter: "Based on the testing we have done through the years, the claims of repelling insects [with sound] are unfounded."

But what about your pets? Will they be affected at all by the device? Ultimately, no specific sound frequency ranges are listed on the Ultrasonic Pest Reject website, and without this information, it’s very difficult to assess how likely your pets are to experience any discomfort from the product.

We reached out to customer service to try and clarify, but were unable to get ahold of an agent as of this writing.

Ultrasonic Pest Reject Pricing & Return Policy

On the product’s main website, the Ultrasonic Pest Reject was available in the following quantities:

  • One device: $39.95
  • Two devices: $69.90
  • Three devices: $95.00
  • Four Devices: $115.00
  • Five devices: $120.00
  • Ten Devices: $200.00

Shipping is listed as being free, regardless of which amount you purchase. As for the return policy, the checkout page lists that all orders are covered by a 90-day guarantee, less shipping & handling charges to get the device back to the manufacturer.

Ultrasonic Pest Reject vs. Alternative Pest Control Devices

Looking around on Amazon and Google, we were able to find dozens of different sonic bug repellent devices available for purchase, many of which featured strikingly similar design cues to the Ultrasonic Pest Reject. Some were so similar, in fact, that they featured the exact same design, with only the branding being changed.

Interestingly, one such product made by Fiery Youth on Amazon was selling for $39.99 per six pack when we checked. Considering this is the price for just one Ultrasonic Pest Reject device, we think this is noteworthy.

What’s more, there were over 1,000 reviews for the product on Amazon as of this writing, but upon further inspection, only a fraction of these were verified purchases, raising some suspicion as to the authenticity of the others.

Outside of pricing and branding, however, there are a few other things you should look out for when considering making a purchase online.

For one, it’s important to always consider any hard, relevant clinical evidence when evaluating the claims made by a particular company, as we did above for the Ultrasonic Pest Reject.

Though we can’t categorically state that a product is ineffective based on this evidence (unless it was specifically used in the tests), we can at least get an idea of how similar technologies are performing.

In addition, before deciding on a pest repellant device, it’s important to know what you’re up against. Because there is so little clinical evidence supporting this type of product, if you’re dealing with a full-scale bug infestation in your home, it may be wise to seek consultation with a professional pest control company before investing in any particular treatment option.

Our Verdict: Ultrasonic Pest Reject

Based on everything that we’ve learned above, can you truly expect the Ultrasonic Pest Reject to live up to its claim of being “the most reliable and technologically advanced” pest-repelling device on the market today?

At the end of the day, without having tested the product for ourselves, we only have relevant clinical data and the reviews of genuine customers to use as tools when evaluating its effectiveness.

Customer service was not available to provide any additional insight when we called, and as noted above, the majority of the clinical trials we encountered online seemed to report mixed-to-negative results when it comes to sonic bug-repellent effectiveness in general.

When you couple this information with the high prices (relative to other products on the market), along with the suspiciously highly-rated, extremely similar-looking competition, as consumers ourselves, we’d find it difficult to rationalize a hasty purchase without knowing more.

Instead, as we discussed above, it might be a better use of your hard-earned money to schedule a consultation with a pest control company directly in order to address the issues you and your family are facing in your home.

Doing so will hopefully place you on the path towards an affordable and effective solution that works for you in the long run.

    Seems like a great idea, BUT, they don't work! I still have a mouse/mice running freely around my kitchen at night. The product is a total scam, especially for the price! I am trying to get refund as we speak.

    Bottom Line: No, I would not recommend this to a friend

    Pest Reject is a reject/scam/deceptive

    I purchased three/four Ultrasonic Pest Reject used for 9 months or so, and the device did not run anything away. Money from senior citizen scam, God watches over the elderly and babies, and he will repay you because he is a just God. Stop and refund everybody. The reviews that stated that it works must get paid!

    Bottom Line: No, I would not recommend this to a friend

    Living in a pest-free home because of this fantastic pest repeller!

    Ultrasonic Pest Reject is the most effective pest repeller I’ve used thus far. The results are actually impressive! My apartment is rather old, so we get ants crawling around the place all the time. I live in a neighborhood with a lot of trees too, so I often catch big houseflies around. After trying a few different pest repellers, I finally found the perfect product: Ultrasonic Pest Reject.

    One of the first pest repellers I’ve tried is AOSHR Ultrasonic Pest Repeller, which wasn’t a very good experience. The instructions claimed to allow a few days in order to clear the insects from the house, so I did exactly that. However, I saw no results whatsoever; there were still ants crawling around. This device was quite a disappointment since it wasn’t even slightly effective.

    Another pest repeller I’ve tried that proved to be more successful in eliminating the ant infestation in my apartment is Ultrasonic Pest Mosquito Repellent Plug Control by EverPest. I was skeptical of the product because it claims it’s a mosquito repellent, but it did a pretty good job at getting the ants out of my home. I’ve noticed that with this product, I see fewer houseflies roaming around, too. The only flaw is that there are still a few spiders crawling around every now and then. It seems like this pest repeller does a nice job getting rid of most insects, but not all of them.

    I was about done with investing in different pest repellers because I was going to settle with EverPest’s device, but I thought it wouldn’t hurt to just try one last pest repeller before settling on my decision. I made the decision to purchase Ultrasonic Pest Reject, and I don’t regret it at all! Not only is this pest repeller really easy to set up and use, it’s also extremely effective. Just like EverPest, Ultrasonic Pest Reject does a fantastic job eliminating ants and houseflies. The difference is that Ultrasonic Pest Reject does an outstanding job getting rid of spiders, too. It’s been a few months using this device, and I’ve yet to have an issue with any insects to this day. Ultrasonic Pest Reject works very quickly; all the pests in my home were gone within a few short weeks. This pest repeller also doesn’t kill any of the pests, so I don’t even have to clean up any dead insects! I love how this pest repeller is eco-friendly, and quick to setup: all you have to do is plug in the unit, so it takes about 5 seconds to set up. I shouldn’t be all that impressed knowing that Ultrasonic Pest Reject was developed by a Stanford Scientist using military frequency technology, but here I am…impressed by how effective the device is!

    I would highly recommend anyone struggling to get rid of insects, mice, or any other pests to invest in this device. For sure, Ultrasonic Pest Repellent deserves 5 stars!

    Bottom Line: Yes, I would recommend this to a friend

    Faulty Ultrasonic Pest repeller

    I purchased three of these Pest Defender Electronic Pest Controls. Two appear to be working, but one does not work (the light does not come on).

    So, how do I get a replacement?

    Pest deterrent

    I bought the product and I have not seen any spiders for weeks. I have had so many spiders, and to my amazement, the spiders that were in my house all died, I saw them on the floor about five days after I plugged it in. No more spiders anywhere. I swear by it. It works.

    You have to activate one on each floor.

    Bottom Line: Yes, I would recommend this to a friend

    Horrible

    I have been trying to return the pest repellents. The company does not answer the phone with a live person. They give you an address to return them, and when I took it to the post office, there is no such address in Hayden, Idaho. My credit card company is aware of the problem. This is very bad for business. I have called the company many times and not once had a person answered.

    Bottom Line: No, I would not recommend this to a friend
