5 KEY CONSIDERATIONS BEFORE YOU BUY
Not all pest repellers work the same way. If you purchase the wrong repeller, you might be disappointed with the results, and you’ll end up wasting your money.[1]
We did a lot of online digging in choosing the best ultrasonic pest repeller for managing a rampant pest control problem. Let’s take a look at these key features of an ultrasonic pest repelled.
1. Ultrasonic Waves & Sounds

Most pests, such as insects and rodents, have strong reactions to high-frequency ultrasonic waves and sounds. However, these ultrasound waves and vibrations are inaudible to humans and other house pets.
The pests stand to be around that type of environment, and the first thing they would do is get away from the high frequency. As you can read in our product reviews above, all ultrasonic pest repellers produce ultrasonic waves.
Ultrasonic pest repellers utilize sound frequencies that create an invisible force field around your premises. This forces your little pest problem out of the house while the ones outside will not want to come anywhere near it.
2. Electronic Pest Repeller Individual Unit Coverage
Each ultrasonic pest repeller has a limit on how much area it can protect. When comparing pest control products, you’ll find that some devices cover a small space like 200 sq ft while others can handle an ample space of 1,600 sq ft or more.
The greater the area a pest repeller can protect, the better value it will bring. You can check out the list of specifications for each of the best ultrasonic pest repellers we’ve reviewed

3. Number of Units Included in an Ultrasonic Repeller

Some brands of ultrasonic pest repellers only sell individual units while others come as a package set.
The number of ultrasonic pest repellers included with your purchase is significant because you may need at least two repellers to eliminate bugs, rats, and mice effectively.
As you learned about ultrasonic pest repellers, these products are limited to the size of the room they’re placed in.
A repeller may advertise that it can protect 1200 sq ft, but if the room you use it in is only 600 sq ft, then that’s all the pest control protection you’re going to need it to get the best results.
Still, if you purchase an ultrasonic device to tackle your pest problem, you’ll most likely get the staple 1200 sq ft range nonetheless. This technology works behind the walls through your wiring system and is not bound by physical barriers.
Keep this concept in mind when you’re shopping for pest repellers, so you know how many devices to purchase. For example, if your residence’s main level is 1,000 sq ft with seven separate rooms, and you buy a single ultrasonic pest repeller that claims to shield 1200 sq ft, it’s not going to cover the whole floor when placing it inside a room.
The walls will block its full radius. In that example, you’ll need to put an ultrasonic pest repeller in every room surrounded by four walls.
In our reviews above, you’ll find recommendations for units that work in a large amount of space. To make it easier for you to make a decision, we’ve included the square footage ratings for two single units of pest repellents, as well as a two, four, and six-pack sets.
4. Electronic Pest Repeller Night Light
Some of the best ultrasonic pest repellers eliminate pests and serve as a night light. An LED is an optional feature many units of pest repellants include.
This feature has a dual purpose. The first purpose is to light up your hallways or rooms to help you see better at night. The second purpose is to act as an additional repellent for certain pests.

Some insects don’t like light, and so they’ll avoid areas that are lit up. You can find in our reviews above which units have night lights.
5. Warranty for Ultrasonic Pest Repeller

A warranty offered by the repellent device manufacturer is another way to ensure that the unit you bought is not a waste of money. This is for additional assurance while having the chance for a replacement or refund within the warranty period.
Other repellent manufacturers even offer a lifetime guarantee. As you can see in our individual product reviews, we stated the warranty.

HOW TO GET THE MOST OUT OF YOUR ULTRASONIC PEST REPELLER
- Follow the manufacturer’s instructions carefully when using your ultrasonic repeller. Each repeller comes with its own set of guidelines and requirements to show overall effective results, such as a recommended distance from the floor, avoiding the placement behind curtains, the best location inside a room, etc.
- Make sure to use the right number of repellers for each room. Every ultrasonic pest repeller and pest control device has a limited range. Therefore, please read the manufacturer’s instructions to find out how far it can reach. Then, put the device in a room that is less than this number or invest in multiple units to protect the intended space fully.
- Be patient. It takes time to eliminate the various type of pests (like two to four weeks), especially if you have severe mice problems. Even a popular device like Neatmaster will take time to show overall significant outcomes. If you find that ants, spiders, mice, or other pests are still invading your residence, wait a few days before you box the unit up and make a return. It’s normal for these critters to make their presence more known after installing an electronic or ultrasonic pest repeller because they’re usually trying to figure their way out of your place of residence. Let the bug repellent do its job before you panic and call in an exterminator.
