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.

    Does not work

    • Albany, NY,
    • Jun 10, 2019
    • Verified Reviewer

    I purchased three units. I have a kitchen, living room and bedroom.

    Placed one in each room. I brought them because I have a mice problem. On the second day that I had them, I was still seeing mice. I placed glue broads out and started catching them on the glue broads. I sent the units back to Pest Defender. I didn't have a problem with the return. Everything about the return had to be done online. There also was a 15% stocking fee.

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

    I mounted it a couple of months ago near the kitchen, where I usually see flying insects, but so far none. It does repel insects in the far reaches of the house or outside of the house.

    I'm so disappointed with your product that is not effective to kill any kind of mosquitos and ants. In the future, I will never ever recommend purchasing this product anyone to like this product. It's totally useless and service is also cheap.

    Dissatisfied

    • Ibadan, Nigeria,

    I saw the advertisement on the Candy Crush game while playing it on my phone. I immediately purchased it online which was brought to me by a man after a few days. To my greatest surprise, I've been using it as recommended and it has no effect whatsoever. I was not given any form with which to return it, no order number given. I paid twelve thousand Naira to the man that brought it. It's my first time of buying a product online.

    A GODSEND!

    I never was bothered by rodents (thank God!), but I had scads of other unwanted creatures such as spiders, centipedes, and ants that I had to contend with. Well, by golly, with Pest Reject they've been banished from my life forever. I am truly grateful I made the investment in Pest Reject and I would recommend it to all my friends.

    It works great for roaches

    • Ft. Lauderdale, FL,
    • Apr 11, 2019
    • Verified Reviewer

    We get roaches coming into the house from the garage every year and we have tried everything with limited results, until we bought two Pest Reject. It takes a little time to get rid of the roaches as they do not like the noise (we cannot hear it) and in three weeks we had no roaches. We tried it for ants but that did not work.

    I had a cockroach infestation that I couldn't get rid of. I tried all sorts of poisons which became vitamins to the roaches. Though I was skeptical of this device, I was desperate, so I bought one. Just one. My apartment has been free of roaches ever since I got this thing. I occasionally see a single roach wandering through my kitchen but nothing like before.

    Bought and never received

    • Boise, ID,
    • Feb 17, 2019
    • Verified Reviewer

    I bought this last week and never received it. My grandson is a toddler and will be walking soon so we don't want snap traps or poisons in the house, especially on the floors, we now have no other alternative because I'm on a VERY limited income and can't afford to try to buy another one, my family lives with me and with mice in the house I worry for my grandson. This woman who refers to herself as "super mom" just because she works out of her home was emailing me and said there's nothing she could do for me because "it was delivered." Forget this. I'm warning everyone I can about this fraudulent company, done.
