Best Budget-Priced Multi-Pack
Key Features:

Large homeowners, take notice – this package of Bocianelli 1237 devices is here to save you both time and money. That’s because this package comes with 6 fully-operable devices for a single flat rate, which is a massive value-added proposition compared to some competing packages with only a single ultrasonic pest repeller unit.

Along the same lines, you might be truly surprised that this Bocianelli 1237 package is so affordably priced. As a result of its 2019 upgrade, this model now includes a new chip technology that allows it to combat rodents, roaches, spiders, and more in only 2-3 weeks. Each unit is designed to cover up to 1,200 sq. ft. as well, making this package a great option for homeowners looking to pest abate several large rooms at once.

Generally speaking, budget-priced ultrasonic pest repellers used to be fairly simple in their operations, with few customizable settings for users to utilize. However, the Bocianelli 1237 has broken this mold by providing an ultrasonic frequency range between 22 and 65 kHz. Accordingly, homeowners with varying high frequency sensitivities can adjust their unit’s operation intensity according to their own needs.

As an added bonus, the Bocianelli 1237’s manufacturer has also noted that it is built from a sturdy ABS plastic. As such, you can expect each device in this set to remain operable if it is ever pushed out of its socket enclosure by accident.

TBI Pro Ultrasonic Pest Repeller

Best Multi-band Option
Key Features:

For several years, technological innovations in the ultrasonic pest repeller industry has felt stagnant. That is, until the TBI Pro Ultrasonic Pest Repeller came on the scene. This innovative device (which comes in a cost saving 2-pack) makes use of a unique pest deterrent system made of three different bands that work in tandem to drive numerous types of flying insects and rodents.

This system, known as Triple Impact, utilizes electromagnetic and negative ion options in addition to regular ultrasonic frequencies. The use of all three of these bands ensures that pests do not become immune to the deterrent sound over time, even if they’re hiding at the very edge of this unit’s massive 2,000 sq. ft. coverage range.

So far as its interface is concerned, the TBI Pro is among the best looking in our collection. In fact, this model specializes at blending into many home decors, even when its nightlight mode or color-coded mode lights are engaged.

Also, unlike many of the budget-priced ultrasonic pest repellers that are pouring onto the market today, the makers of the TBI Pro are proud to say that this model was designed in Chicago, Illinois, USA. As such, you can generally count on it to meet all of its advertised performance standards, even after using the device for several successive years.

Best Low Power Consumption Option
Key Features:

Next up, let’s have a look at the U Pest Pro Ultrasonic Pest Repeller, which is one of the prime low power consumption options in our collection. With just a minimal continuous energy draw, this model is able to satisfactorily combine ultrasonic and electromagnetic waves into a single, effective mode of pest abatement. This new hybrid method is new in this 2019 model, also, so don’t go looking for an older, cheaper model and expect the same standard of results.

The U Pest Pro model excels when it comes to versatility in placement, which can be a major boon for folks who intend to install their ultrasonic pest repellers in a warehouse, office, or hotel. For example, this model can be installed into a power outlet anywhere between 20 and 80 cm from the floor and still manage to output a high frequency sound that reaches large and small pests.

At the same time, the U Pest Pro’s impressive range will allow you to make the most of its capabilities when installed in one of the aforementioned open spaces. In some cases, this model’s 1,600 sq. ft. of coverage range can be utilized around corners and through doors where other ultrasonic pest repellers cannot reach.

Best Non-Toxic Option
Key Features:

Without a traditional digital screen, ultrasonic pest repellers can often be rather challenging to interact with and manipulate. While the Neatmaster Ultrasonic Pest Repeller may not solve all of these problems, it has taken a major step forward on this front by incorporating color-coordinated faceplate lights that indicate which of the unit’s three intensity modes is active.

Speaking of this Neatmaster model’s faceplate, seasoned ultrasonic pest repeller users will be quick to notice that this model has done something unique on its user-facing side. Specifically, prospective users will be interested to learn that the orientation and shape of this model’s output grate allows it to effectively spread its high-pitched sound far and wide across a 1,200 sq. ft. room.

Also, in an ideal situation, your bothersome target pests would simply die off once they are out of your home. But unfortunately, traditional ultrasonic pest repellers have a tendency to cause this mortal outcome while the pest in question is still in proximity. This Neatmaster has gone a long way towards preventing such a messy result by implementing a more balanced frequency wavelength across all three of its operational modes.

Finally, a note must be made regarding this model’s weight. At only 4 ounces, it is surprisingly able to hold onto any power outlet without risking falling out under its own weight (as some of its bulkier competitors tend to do).

Speaking of infestations, the Neatmaster Dual Microchip is one of the only models on the market today that is certified to keep silverfish, wasps, millipedes, and much more at bay.

How Ultrasonic Pest Repellers Work

ultrasonic pest control

If this is your first time hearing about ultrasonic pest repellers, then you’re not alone. Though most homeowners are familiar with mechanical rat traps and chemical “roach motels,” many haven’t seen an ultrasonic pest repeller in action due to their generally scare availability in retail stores.

In order to remedy any remaining confusion about these devices, let’s take a moment to break down their basic operation.

Let’s start from the moment you take your first ultrasonic pest repeller out of the package. You’ll immediately notice that they resemble a plug-in nightlight, to a degree, and are powered in much the same way. As such, you’ll only need a single electrical outlet in the pest-effected area in order to operate an ultrasonic pest repeller.

Once the device is powered up, you’ll likely see a small operational light turn on. This generally indicates that the unit is active and emitting its primary method of deterring pests. To be specific, your device will begin to emit an ultrasonic noise that causes discomfort to small pests (such as bugs and mice) and causes them to steer clear of that particular area.

In almost all cases, this ultrasonic sound’s frequency is higher than human ears can detect, which prevents an ultrasonic pest repeller from becoming a bother when used in a trafficked area. Also, most pets are unbothered by these same ultrasonic frequencies, thus allowing them to roam around freely in a manner unavailable to users of chemical deterrents.

In terms of operational effectiveness, it is well understood that ultrasonic pest repellers tend to take a couple weeks to reach their peak efficiency. This is because the use of ultrasonic sound is designed to create a lasting psychological impact among a pest population, which requires some time to pass in order for the effect to collectively set in.

One potential downside of an ultrasonic pest repeller’s primary operation is that they do not outright eliminate a pest, but rather forces them to move to a location where they are unbothered by the high frequency sounds (which may still be in your home). Accordingly, it is wise to invest in several ultrasonic pest repellers that can be placed strategically in a portion of your home (such as an attic or basement) where your home’s problem pests are most likely to roam.

Tips for Using your Ultrasonic Pest Repellers

use technology to get rid of cockroaches

New ultrasonic pest repeller users often question why their new in-home abatement system is operating less efficiently than advertised. As it turns out, there are a number of common mistakes that new users make that cause their ultrasonic pest repellent system to miss the mark.

These are a few tips that you should keep in mind if you want to achieve full satisfaction from your new ultrasonic pest repeller system.

Tip #1 – Remove Any Attractants from the Effected Area

At face value, this tip may feel obvious. But in fact, many homeowners forgo the crucial step of removing known attractants from a pest-effected area prior to installing their ultrasonic pest repellers. If left unaddressed, strong attractants can completely counteract your deterrent by successively attracting in new generations of pest, which in turn perpetuates the infestation cycle.

When it comes to “large” pests like mice and rats, know that they are primarily attracted by food products that smell good to their sensitive noses. As such, any foods (as well as potential nesting materials, such as straw) should be removed from the affected area prior to plugging in your first ultrasonic pest repellers.

As for “small” pests, including bugs and arachnids, particular attractants will vary from species to species. As such, you should consult with a certified pest specialist prior to starting an ultrasonic pest repeller regimen to ensure that any outlying attractants are identified and removed from the affected area.

Tip #2 – Strength in Numbers

Similar to other forms of pest deterrence, ultrasonic pest repellers work best when they are installed in groups. In other words, you can expect the best results from these devices to occur when you spread several out within an effected space (even within the individual units’ listed coverage range).

This need for strength through numbers is a direct result of an ultrasonic pest repeller’s operational methods and the expected behavior of your target pests. Specifically, pests will usually try to move away from a psychological deterrent such as a high-pitched sound while still navigating towards their desired target.

A web of ultrasonic pest repellers can prevent your target pests from padding out a new path through your home simply to avoid your lone plug-in device. This is particularly true when you are trying to blanket a broad area with several walls, which the pests may try to use to hide from the sound while remaining within their target area.

Tip #3 – Proper Spacing

As an extension of tip #2, you should always place your several ultrasonic pest repellers such that they are properly spaced apart. While this maximizes your coverage range, it also ensures that your devices’ output high-pitched sounds are traveling throughout the affected space at a level that will reach the pests’ auditory receptors.

Spacing for ultrasonic pest repellers tends to fall into two categories. The first is spacing from the floor, which is listed on most modern models at around 80 cm. The seconds spacing metric involves distance between individual ultrasonic pest repeller units. Spacing, in this latter category, will vary from model to model, based mostly upon the unit’s effective coverage range.

Tip #4 – Be Willing to Be Patient

There’s an old saying about patience being a virtue, and when it comes to ultrasonic pest repellers, the same idea rings true. In order to reach the peak repellant potential for one of these devices, you will need to wait for a moderate period of time after plugging in your first unit.

Generally speaking, this need to wait is a direct result of the ultrasonic pest repeller’s primary method of dissuading pests. As it turns out, it can take up to several weeks for an established pest population succumb to the effects of a high frequency sound. However, specific waiting periods will differ depending on the strength of your devices, their placement, and the resilience of your target pests.

However, after waiting for the amount of time prescribed by your chosen ultrasonic pest repeller, you may opt to check the previous tips on this list to ensure that you are using the device properly. Otherwise, you may need to try out a different ultrasonic pest repeller model in order to achieve your desired pest deterrent goals.

Ultrasonic Pest Control Buying Guide

Target Pests

If you’re planning on investing in ultrasonic pest control, then your primary goal is likely to abate a couple specific pests from all of or part of your home. Not all ultrasonic pest repellers are built with equal capabilities to deter all types of rodent and insect pests, so it is crucial to pick out a model that has been specifically tested to work efficiently when combating your home’s pests.

Along the same lines, you should only select ultrasonic pest repeller models that specifically list their target pests. Those that only indicate that they deter “rodents and pests” or a similar sentiment may be too weak to actually accomplish their primary task in a timely manner (if at all).


Naturally, you should try to find a competitively priced option while shopping for your next ultrasonic pest repeller. This is particularly true when it comes to getting extra value for your dollar through a multi-pack, with several deterrent devices for a flat price.

That being said, single units that are priced similarly to a multi-pack may be well worth it if they are equipped with special features that justify their price point.

Frequency Limits/Ranges and Pet Safety

As their name suggests, ultrasonic pest repeller rely on high-pitched sound in order to deter pests from your home’s interior. However, most modern models rely on a range of frequencies that provide users with intensity options based upon the state of their infestation. In the product’s listing, this may be referred to as either the frequency range or frequency limit.

At the low end of these ranges, output frequencies are entirely inaudible to humans. However, as you increase the frequency on some high-powered devices, you may begin to hear a slight hum emitting from the unit. For the most part, this hum will not bother or harm cats or dogs (though some rodent pets, such as Guinea pigs, may find the noise troubling).

Extra Features

Some newer ultrasonic pest repeller are known to include extra features that make them useful beyond simply deterring pests. For example, one popular model includes an ion generator that may be able to improve air quality, while other models include an optional nightlight setting.

FAQ – Frequently Asked Questions about Ultrasonic Pest Repeller

How many ultrasonic pest repellers do you need?

In theory, most pest infested spaces will only need a single ultrasonic pest repeller unit in order to effectively blanket the space in high pitched sound. That being said, unusual home architectures can sometimes make it challenging to accomplish such full coverage with a single device alone.

Accordioning, prospective users should evaluate their space before investing in one or more ultrasonic pest repellers. In particular, prospective users should purchase enough devices to cover the entirety of the effected space while allowing for some overlap.

Are ultrasonic pest repellers safe for use around pets?

So far as common household pets are concerned (that is, dogs, cats, and birds), ultrasonic pest repellers have not been shown to substantially harm these pets or noticeably decrease their quality of life. However, some smaller pets (such as rabbits and Guinea pigs) that are closer in size to common household pests may be noticeably bothered if they are allowed to roam in the area of an active ultrasonic device.

Do ultrasonic pest repellers produce any noise?

In technical terms, yes, all ultrasonic pest repellant devices produce noise. However, in almost all cases, this noise is output at a higher frequency than humans can hear. As such, you are not likely to notice an ultrasonic pest repeller when it is active.

However, some high-power units are known to make a noticeable hum when cranked up to their maximum output frequency. This hum may be even more noticeable for people with hearing aid devices, due the sensitive nature of those devices’ sound collection apparatuses.


If you came into this guide knowing nothing about ultrasonic pest repellers, you can now consider yourself a bit wiser when it comes to implementing this innovative insect and rodent abatement method. More importantly, you know what to look for when shopping for one of these devices as well as how to optimally use said devices once you’ve brought them home.

However, when it comes down to it, you may still be having a tough time deciding which of the top-tier ultrasonic pest repeller reviewed above is right for you. Through and through, we still recommend the Neatmaster Dual Microchip Ultrasonic Pest Repeller, primarily due to its user-friendly interface and exceptionally long list of certified target pests.

Should you be angling for a more budget-friendly option, the 6-piece value packs provided by both the Bocianelli 1237 and the U Pest Pro will surely prevent you from breaking the bank.
