Comparative Review of 3 Best Ultrasonic Pest Repellers: Bell Howell, Riddex, Uhome

None of us wants to share the dwelling with rats or mice. You might have used homemade remedies with no result! No wonder, as the rodents that have settled in your home, are too smart to leave just like that, without a fight. To get rid of them, you need more serious methods… But what if you’re not ready yet to spend a fortune on that? The solution is to purchase an affordable budget ultrasonic pest repeller, that doesn’t make you go bankrupt. They are sold in sets (from 2 to 4 pieces per set), and it turns out that one unit is very cheap.

This review covers three best electronic & ultrasonic pest repellers and we’ll answer all of your questions concerning the segment of cut-rate pest repellers. Are they really effective? How many of them are needed for home use? Which repeller is the best for a given price niche?

What Are Cheap Electronic Pest Repellers?

In the category of inexpensive ultrasonic repellers you’ll find tens and even hundreds of different devices, but unfortunately, most of them are one-day devices. In order not to run into a useless item, you’d better choose proven older items that have long been on the market and are well-known to the customers. Among them, there are no perfect repellers as their operation is influenced by many factors, including rodent infestation scale, size of the house, other measures taken to eliminate mice or rats etc. The efficiency of a repeller depends even on the number of objects in the room and the condition of the wiring! It is not surprising therefore that even the most proven products can receive conflicting reviews and their ratings are often quite modest.

3 Best Indoor Pest Repellers For Up To $25

Among the cut-rate repellers you won’t find sophisticated gadgets, there are only simple shapes, cheap plastic, and ease of operation with minimum functions. Such pest repellers are usually sold in sets of 2 to 4 pieces. This is very economic and simplifies the process of getting rid of rats and mice in different rooms of the house greatly (producers claim that the repellers work against pest insects, too, but it’s a moot point). We have studied the entire budget segment, and below we’ll focus on the 3 best-selling economy-class rodent repellers which are praised by the customers.

Bell + Howell Ultrasonic Pest Repeller

The Most Popular Home or Office Device

Bell + Howell Ultrasonic Pest Repeller Home Kit (Pack of 4), Ultrasonic Pest Repeller, Pest Repellent for Home, Bedroom, Office, Kitchen, Warehouse, Hotel

Bell repeller pack has been sold for a long time. For this price you’ll get a pack of 4 repellers, which will be sufficient for all rodent-infested rooms in a small house or office. The principle of its operation lies in the combination of ultrasonic waves and electromagnetic radiation for repelling rats, mice, spiders, ants and cockroaches… that’s what the manufacturer says, at least. But we advise you not to have any illusions about the repelling effect on insects and to use other measures against the latter. It really does deter rodents, judging by the reviews of satisfied users.

Who doesn’t know what Riddex Repeller is? This device has been known to homeowners for a long time: many people first saw it on TV as old as 15 years ago. Riddex Sonic Plus is the very same repeller, but in a different design, and it is now sold in a set of 3 pieces. Like many similar devices, it has been positioned as universal: the manufacturer assures that Riddex Sonic Plus is able to scare away rodents and insects within the area up to 1059 sq. ft. The users point out that it is not good against all kinds of rodents, but only against mice. See for yourself, whether it is true, as the feedback is different.

What is the radical novelty of the new Riddex against the old one? The manufacturer proved to be customer-oriented and upgraded the device. First, there appeared a new feature: it now has a built-in side outlet, which will allow using a socket without turning the repeller off. Second, many users complained that the outdated version of the device affected the operation of other electrical devices. Now the problem has been solved.

Pest Control Against Mouse – uHome Pest Repellent

Bonide Repels-All Animal Repellent Granules, 3 lbs. Ready-to-Use Deer & Rabbit Repellent, Deter Pests from Lawn & Garden

Just like all other repellers, it is promised to drive all types of pests out by highly-effective ultrasonic frequencies”. In reality it turns out to be especially effective against mice: just like Riddex. Though, mind that the manufacturer promises that it can take up to 4 weeks in case of severe infestation.

It’s coverage area reaches up to 1,100 Sq. Ft, but unlike other manufacturers, uHome frankly warns you that ultrasound cannot bend around corners in the room and penetrate solid surfaces, such as ceilings, walls, furniture, etc. Therefore, even having such a large coverage area, one unit for each room will be required. If you have a small rodent infestation (e.g., rats are only found in the basement) and a limited budget, this set is just what you need to keep the rodents away from your house.


Let us be honest though, most cheap repellers do not have very high ratings: on average they are rated at ~3 of 5 stars while the bestsellers’ ratings start from 3.9 stars.

Then, trust proven items and check out repellers of better quality, with more options and coverage area. For example, you may use the set of 4 Ultrasonic Pest Repellers by Pest Venator that repels pests (rats, mice etc.) in an area of more than 3200 sq ft. It is safe for children, adults, pets.

FAQ: Do Ultrasonic Repellers Really Work?

Many scientists worldwide study the effect of ultrasonic pest repellers on insects. Certain research is devoted to mosquitoes, cockroaches, flies, fleas, and other insects, and the entomologists are unanimous that at the moment no electronic ultrasonic repellers are effective against insects.

The possibilities of such devices have not been fully studied yet, though. The Kansas State University scientists are encouraging, for instance and claim that: “Our studies with a random ultrasound generating device using higher sound frequencies than those reported previously by researchers, confirmed ultrasound to be ineffective in repelling mosquitoes and German cockroaches.  However,  future  studies  using  ultrasound  as  an effective  means  of  controlling  pest  behavior  is  still  open”.

Do ultrasonic pest repellers work on spiders?

No, ultrasonic pest repellers don’t work on spiders. Ultrasonic waves’ action on rodents is limited and is ineffective against insects. Many repeller manufacturers mislead the users, promising that their products will eliminate any insect infestation. Do not get fooled, remember, that the scientists believe that this is impossible.

Do ultrasonic pest repellers work on scorpions?

No, just like in case of spiders and other insects, ultrasonic pest repellers are useless against scorpions. Scorpions are impossible to repel and very difficult to eliminate with insecticides. To avoid their infestation at home or in your backyard, get rid of the trash near you house, sources of stagnant water, repair all the cracks in the foundation and make sure that the windows and the doors are securely shut.

I used to have ants at home, and they were gone after I used the electronic insect repeller. Does that prove that such gadgets are effective against ants?

Unfortunately, this must be a coincidence. Usually such cases are observed when you simultaneously use other ant control products, such as insecticides. It is them that are effective.
