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.

    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.

    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!

    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.

    I got this pest to reject about a month ago. I have a severe ant problem and this thing does not work at all. My ant problem got worse instead of better. It's a white device and red inside the circle. It cost a lot of money. I could have gotten one cheaper, but I thought this one would really work. LOL. Right.

    I bought five Pest Rejects and I am not happy with them. I have received more pests in my home than before. I went to Rite Aid and bought three more of a different brand and they work way better. I will be glad to send them back with a refund.

    They don't work. I have six, one in each room, for a month and still had mice and crickets. So they told me to leave them in for another month as one month is not enough time. So now my 30-day money back guarantee is expired, and I still have mice and crickets in my house. Let's see if this review gets posted, my guess probably not.

    Pest Reject is not working, it's a scam, probably it's good for light. I bought three because I saw some bugs in my house but it's not working. I still have the bugs and those devices are not doing anything except blue light. I do not recommend this product to anyone, it's not working.

    I bought one about a month ago. The apartment complex I live in offers free pest control service if asked. So I rarely see any bugs. I thought this device would keep away all pests so I would not see any. Like I said earlier, I hardly see bugs, so I didn’t know if it was working. Then one day I walked into my bathroom (where it is plugged in) and there was a silverfish running around. A couple of days ago I went to take a shower and there was a water bug, roach, tree roach or whatever you want to call it in my bathtub. The big brown one. So no, this product does not work.

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

  • Total BS

    I purchased the Ultrasonic Pest Reject for $35, what a dummy I am to believe such BS. This product is a complete scam! How do I know? I placed it in an A/C receptacle approximately 5 feet from an area I know I have mice. And guess what? NOTHING, same mice problem. Not effective AT ALL. Do NOT waste your money! The jerks who sell this are laughing all the way to the bank! Yeah right, Stanford Scientist by butt!

    You've been warned.

    This thing is junk! It's a scam. I'm a clean freak. My neighbors have cockroaches, so I ordered one to be on the safe side because I'm terrified of a cockroach. I have never seen one in my house, but earlier today, there was a cockroach in it! What the heck. I threw it in the trash.

  • Pest Reject, don't waste your money

    I bought two of the Pest Reject items, saw them on Facebook. I had mice in my kitchen, set two traps I bought at Home Depot, caught one. So I bought the glue type, that caught three of them, and my dog got one. At last the Pest Reject items came and I plugged them in about three weeks ago. By the way, they got smart and avoid the glue traps now, saw them jump right over it. Every morning I have mouse droppings on my kitchen counter, sink, and stove. I clean it up every morning hoping not to see any the next day, but after three weeks and still cleaning mouse droppings, I feel I got took.

    I can't provide the order number to this review as my wife threw away the box with whatever information was in it.

    Don't waste your money!

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