About Ultrasonic Pest Reject

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 and 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 was 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?

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, we 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.

    We had a small roach problem. Since we installed 8 of these our roaches have grown 10 times the number. After $180 on this device, we now are paying 100's of dollars in exterminator fees.

    Overall Experience:

    This is a product they claim will remove mice from your home. We bought 3 units totaling $107.45. We saw no improvement concerning mice activity. They seemed to be completely unaware. It did not work.

    We returned the product with the original packaging as they demand. It was returned on 10/29/2019 and the company does not dispute that they received the product back.

    Here’s the maddening part. They send emails assuring you that the refund is "being processed" but you never actually get the refund. I have a dozen emails saying exactly that. My guess is most people give up (yes, I realize it’s "only" $100 and that’s what they depend on).

    It’s a scam.

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

    Overall Experience:

    We bought a rural property a year ago, erecting a pole barn on a cement slab for RV and other vehicles. Shortly after moving in we found evidence of mice in the poor cabin and in the new pole barn. We sealed the bottom of the pole barn and laid traps there catching quite a few critters out there, in the cabin we did the same. I installed 3 Pest Reject devices in the pole barn, and the fourth in the cabin next to the sink. No evidence of rodents since May 2019.

    Important to deny entry, then the devices sound appears to discourage new residences.

    We are happy with the "Blue Light" devices and recommend.

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

    I purchased 4 Pest Rejects and used them in various places in my house over 4 weeks. I returned them in the original box as requested and was never sent a refund. They claimed to have sent it but I never received it. I call them weekly asking for a refund but they don’t have a supervisor and won’t connect me to billing.

    Overall Experience:

    First of all, I think the 30-day return policy should be the first red flag, they say give this product 2 to 3 weeks, if I have a product that works why would they even be a return policy, just saying. Anyway, I gave it 4 weeks, did not matter, nothing, I paid one hundred dollars for a night light. At least it could have been a little brighter. Waited too late to get a refund and no one is calling back. Should have done some research, my mistake, hate dishonest people.

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

    Overall Experience:

    I bought the four-pack of Pest Reject some time ago. Placed them all around the house, including the garage, and as of to date the rodents are still here. The devices simply have not done as advertised. I am sorry that I wasted my money on these items. I had to call the Pest Control company to get any control of the situation! I am not looking for a refund or replacement, just want your company to know that your product simply does not work!

    Overall Experience:

    I purchased a pack of four Pest Reject devices. I placed one in the pantry (approximately 4'x4'), in the next room to the pantry, and two in a bedroom. These devices do not appear to work. I even saw a moth crawling on one. They appear to be a waste of your money and give you false hope of riddance. I don't know about other pests, but I know they do not work for pantry moths.

    The Pest Rejects do not work. I still have spiders and mice in my house. It worked for a month and that' it. It shows that it works but it doesn't. They need to take it off the market because it won't work.

    Overall Experience:

    This product is a joke. I bought 2 of these and it made the problem worse. This product is only good for the trash can, throw it away. It does not keep critters away, it brings them out hot and heavy. Please do not waste your hard-earned money on this. I will be contacting the Better Business about this. The one who is selling this is taking money from people, it is a scam. I will be letting everyone know.

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