Most Affordable: Pest Soldier Ultrasonic Pest Repellers

If you’re looking for the absolute cheapest solution on this list, these ultrasonic pest repellers from Pest Soldier come in a set of four for less than $20.

Over 5,000 Amazon users have invested in this four-pack and given it an overall rating of 4.2 stars.

Got to a point where I would find baby roaches with their mommas inside the fridge. I was going crazy killing and polluting my house with all kinds of chemicals and they would just hide inside the edges. But not after this amazing product! It gave me great relief and after just plugging it in four places in my house, the roaches were disappearing and [I] saw them less. Also, my fridge was cockroach-free.”

Best For Outdoors: ZOVENCHI Ultrasonic Animal Pest Repellent

To tackle pest problems before they even reach the house, this solar-powered repeller is great for outdoor use. Here's how they work: Each repeller features a stake that you place directly into the soil or grass near your home. The solar panel on top traps in solar rays to charge the device, which releases an inaudible, high-frequency tone through the ultrasonic speakers in the device. This tone prevents rodents, skunks, squirrels, foxes, and other pets from approaching your home, and both repellers combined cover a surface area of up to 2,425 square feet.

According to one reviewer: "We were about to give up on our beautiful vegetable garden. Groundhogs and rabbits were having a feast daily without leaving a single lettuce leave for us to enjoy. My husband bought this repellent and it makes a sound the second you enter the zone. The light and noise is so unpleasant to even human ears. Those pests definitely stay sway from the garden for good. So happy, finally!”

Best Signal-Changing Pest Repeller: MaxMoxie Ultrasonic Pest Repeller

Something that customers love about the MaxMoxie pest repeller is the fact that it goes above and beyond. Sold in a set of two plug-in units, these are great at emitting tones to help disturb pests and rodents without being bothersome to humans. The company believes that within a few weeks, pest issues should minimize with these units in place. Even better, they change the tone on occasion so that pests don’t get used to the same sound.

According to one reviewer: “Within a couple of days of using the repeller, I trapped two mice and haven't heard another in weeks. The literature with the repeller states that you must use multiple systems to get rid of mice. I used traps and the repeller. My theory is that the signal from the repeller drove the mice out of the corner and into the traps. One thing nice about the repeller is that it constantly changes the frequency of the signal so that the mice don't get used to it. I have read where mice can get accustomed to a constant signal. Would recommend it to everyone.”

Best For Cars: Laraffe Under Hood Animal Repeller

If you’re dealing with unwanted pests in your car, this under-hood pest repeller is great for repelling mice and rats that can chew wiring or damage your car’s engine. This repeller emits a combination of ultrasonic sounds and LED flashing lights to deter animals from nestling under your car’s hood, particularly prevalent in the cold weather months. It also has built-in voltage protection to protect your car’s battery.

According to one reviewer: “If you have problems with rats, mice or squirrels chewing up things under the hood of your car, then I recommend getting one of these units. I’ve been using them for years, after trying nearly everything else. Don’t get the ones that run on batteries, or you will end up having to replace the batteries every 5-6 months IF YOU REMEMBER! With this type of unit, it hooks up to your car battery and you never have to worry about it again.”

Best For Rodents: CLEANRTH CR008 Advanced Ultrasonic Rodent Repelling System

While a number of the ultrasonic pest repellers on this list will repel rodents, this one by CLEANRTH is specifically designed to combat them, and works on spaces up to 7,000 square feet, far and away the best radius of any repeller on this list. Reviewers dealing with rats, mice, squirrels, and other rodents have had a lot of luck with this. And, many Amazon users particularly praise the customer service of this company, which is especially important when dealing with pest repellers, which are notoriously finicky.

According to one reviewer: “This product does what it says it will do — it gets rid of rodents! And it's incredibly easy to use. You just plug it in and leave it alone. We had a small mouse problem, but do no more. Thank you, Cleanrth!”

The Cult-Favorite: Neatmaster Ultrasonic Pest Repeller

With 19,000 Amazon reviews and counting, this plug-in pest controller can cover up to 120 square meters (roughly 393 square feet) and features different "modes" to maximize efficiency for different pests. Like other devices, this option blasts out irritating frequencies for pests throughout your entire home. Green and blue modes are completely inaudible, while red is loud and noisy for those pests that just won't leave. On top of all that, it repels just about any and every pest you can imagine, including rodents, bedbugs, mosquitos, spiders, and cockroaches.

According to one reviewer: “I first bought these gadgets in black and put one in the garage and one in the unfinished basement. Both areas were crawling with spiders and insects. After about a week or two I notice a considerable decline in the amount of insects I saw in both areas. There were less spider webs, less mosquitoes, and other insects. My wife was so impressed we bought 2 more for indoors (white), one on the main floor and one in our bedroom, she hates the sight of anything crawling.”

Also Great: Victor M756K Pestchasers

These mini ultrasonic repellers are perfect if you're looking to get rid of rodents, specifically. The high-frequency tone these emit is effective at ridding your home of rodents, while also doubling as a soothing night light. Each repeller in this pack of six features a small, blue ring that isn't overpowering. Plug them into your bathroom, kitchen, or hallway in place of a regular old night light. One note: Because these repellers are so small (and are only equipped to handle 400 square feet apiece), Amazon reviewers suggest using a few in larger spaces.

According to one reviewer: "We use these to make the critters leave their hiding spots and run in a particular direction toward humane traps. We don't keep them plugged in, but use them in sequence. Plugging in one after the other to corral the wee beasties. So far so good!”
