The device uses three types of waves to maximize effectiveness, sending out pulses at frequencies ranging from 20 to 158 kHz. That way it's equally efficient both indoors and outdoors.
You only get 1 repeller in the set.
Though the set contains nothing but repellent itself, it's so powerful it can cover a large area and expel inspects and rodents from your whole house. The effective radius of the TangN repellent is 360°, it has an LCD screen, and it can be set both indoors and outdoors.

A Lone Guardian
As the summertime comes, bringing the stifling heat with it, it becomes impossible to resist the temptation of opening a window to let some fresh air in. However, since the breeze brings along not only cool air but also all sorts of bugs and pets with it, in order to enjoy the chillness you'll need to have a guardian to stand watch in your bedroom so that no mite could possibly get in. We find the TangN Electromagnetic pest repellent to be just the right device perfectly fit for this job.
Although the TangN Electromagnetic pest repellent includes only one piece, it is powerful enough to instil in pesky insects a real fear without any additional help. In addition to ultrasonic sound waves, this device emits electromagnetic pulses and optical deworming impulses ranging between 20 and 158 kHz, which makes a large enough amplitude to influence all sorts of bugs and rodents. This, along with the effective coverage area (1076 sq. ft) and the ability to send signals in a 360° radius, is what makes the TangN Electromagnetic pest repellent suitable for use not only indoors but also outdoors if need be. Another benefit of this repellent is that it has a handy LCD screen that makes it easy to track its operation.
While it's tough to say what specific characteristics make the best ultrasonic pest repeller, we'd think that a large coverage area and a circular emission radius are certainly up there in terms of importance. And the TangN Electromagnetic pest repellent fits these criteria to a tee. So if you need a no-nonsense solution to tackle your bug problem, the TangN Electromagnetic repellent should be right up your alley.
Bell + Howell Pack of 3
Pest infestations are especially noticeable in small apartments where a single roach scurrying behind the couch is a sign of big trouble. Luckily, you can keep the critters at bay with the Bell + Howell Pack of 3 electric repellers.
Though this deterrent set doesn’t have the widest coverage radius, totaling about 300 square feet, it’s going to be more than enough for an apartment or a smaller house. Besides, the units are so small and portable that you could place them all over a single room if you know for a fact that it’s where the source of the insect activity is. Don’t worry about houseguests noticing the device as its small white body looks just like an anti mosquito repellent, common to all homes and nothing to be ashamed of. With this set, nobody will even know you’re fighting a battle against rodent or insect infestations.
Now, this model uses ultrasonic signals to deter pests, which means it’s not too restricted by any walls or obstacles. You could plug it in on one side of the wall and let the signal seep through to the other, spooking away any critters hiding in the walls (common for rodents).
While we concede that the coverage radius could have been better, the Bell + Howell pack is a solid pick for smaller premises and those who want a discreet tool for pest control.
Pest Control on a Bigger Scale
While some people have modestly-sized homes and don’t need that much stopping power to drive every single rat, mouse, or similar animal out of their territory, some farmers and owners of land plots need something more powerful. With that in mind, we recommend the Kantora 6-Pack set of electronic bug repellers.
Every single unit in the set covers from 800 to 1200 square feet, which means you could safeguard up to 7200 square feet if you use the whole set. If you frequently have trouble with rodents ruining your crops or digging up your flowerbeds, the high frequency repellers from Kantora will solve the problem. They use both ultrasonic and electromagnetic impulses to scare off any pests in the area and they’re not deterred by thick walls or furniture getting in the way.
Admittedly, there is one big flaw to address here, namely the time it takes for the repellers to show their effects. You’ll have to wait up to 6 weeks before you finally see the pests reject your home as a viable living place. However, once the process starts, it’s pretty speedy and guaranteed to keep rodents and insects away for a long time so we’d say the wait is worth it. All in all, there’s no better choice than the Kanotra 6-Pack if you need to rid a large area of pesky bugs and critters. If you’re ready to wait to see the results, this set of six reliable repellers is more than worth it.
Adoric 2 Pack
Leave a Light On
If your kids are getting spooked by scratches in the night, you need to not only get rid of the pesky rodents or insects disturbing your child’s sleep but also alleviate the fear by bringing some light into their bedroom. For that, we recommend the Adoric set of 2 powerful repellers.
Each of the units can cover anywhere from 800 to 1200 square feet and, since they use both ultrasonic and electromagnetic technology, they aren’t stopped by walls or furniture. This means you can plug the little devices anywhere in your office or home and still get rid of pests in any corner of your home. Well, anywhere as long as there’s a bit of space since these repellers are one of the bulkiest on the market.
But though you can put it anywhere, we feel that the powerful built-in night light makes the Adoric set of dual repellers perfect for a child’s bedroom or a hallway that you might use at night, like if you’re going to the bathroom, for example. That way you get illumination where it’s needed most and still get the benefit of driving rodents and insects out of your home regardless of placement choices.
So if you want a safe and effective way to kick unwanted animal and insect lodgers away from the house, the Adoric 2 Pack of repellers is an affordable and eco-friendly choice. It will light up your home and keep it free of pests.
MaxMoxie 2 Pack
Light 'Em Up
If you’re living in a large home, you know how many nooks and crannies there are for mice and cockroach packs to hide. Instead of using bug spray or calling exterminators, we recommend you save money and still drive the critters out of your home by using the MaxMoxie set.
Just one unit out of this duo is enough to cover 1200 square feet, a whole house worth of territory. We still recommend using both, though, to make sure you’ve covered every single inch of your home and driven the pests out of the premises, not just into hiding in some remote corner.
As always, the device simply needs to be plugged into an electric outlet and works automatically from there on out. You can make sure it’s on and functional by checking the LED indicator which, admittedly, is pretty bright. Thus, we recommend plugging the repeller somewhere where the light won’t bother you. Conversely, if you want to keep the unit in your child’s bedroom and your kid is scared of the dark, you can use the handy nightlight function to keep things illuminated and deter critters from scurrying across the floor in the night.
Not even a flea will pass by the MaxMoxie airtight security and this is one of the best ultrasonic pest repeller sets in terms of coverage and efficiency, using just 6 W of energy for operation. If you want a pest-free home and want the results achieved with little money spent, this is a great option.
What Is an Ultrasonic Pest Repeller?
Despite looking like some futuristic device, an ultrasonic pest repeller is quite simple, both in its purpose and operation. Plug in this bug control gizmo into any free socket and it’s going to send waves all over the room making critters scatter in fear. These ultrasonic pulses are a great way to tell insects and rodents to bug off and leave your household without causing any harm to its legal inhabitants. And though not every type of mite might be scared by these impulses, most of the domestic pests will run away cowering. Ultrasonic waves bounce around the room, reaching pretty much any living creature inside it, but affect only small beings that have a very specific biological makeup. Unless you’ve been born with ant-like antennas or super-precise sensors that pick up the lowest sound waves, the repellents won’t do a thing to you.
