Having pests invade your home is a nuisance and makes your house vulnerable to germs and disease. And when it comes to calling an exterminator, things can get quite pricey. However, investing in some of the best pest repellents is a great way to protect your home from mice, snakes, spiders, insects, bed bugs and other critters.
The best types of pest repellent are ultrasonic vibrations and pest-discouraging chemical formulas. These methods are largely effective and typically nontoxic, making them safe for use in your home and around children and pets. You might be wondering how these two methods work, so let us explain. Below, we’ll also explore the efficiency of everyone’s favorite pest repellent hack, peppermint oil.
What Are Ultrasonic Repellents?
Ultrasonic repellents emit high-frequency sound waves, which in turn deter pests from entering your dwelling space. These sonic wave devices are typically designed in a frequency that humans can’t hear. Many ultrasonic pest repellents plug into your outlets, but others are battery-powered or solar-powered for outdoor use. The latter can be placed in corners to ward off gophers, groundhogs, and other critters and to prevent them from destroying your landscape.
What Are Formula Repellents?
Formula-based repellents usually come in spray bottles or pouches and use either toxic or nontoxic ingredients, such as essential oils or vinegar to keep pests away. We should note that some of these can leave a scent behind, and many can be hazardous to pets if consumed. So be sure to read the label before purchasing, especially if you have fur babies or small children in the house.
Whether you’re trying to prevent pests from entering or expelling pests that have already invaded, take a look below at our selection of the 22 best pest repellents you can buy on Amazon. A pest-free home is a happy home.

Pest Repellents FAQs
It turns out, there are a lot of questions about pest repellents. After all, most consumers want to know that they’re buying the one that will really work to keep mice, bugs and other pests away from their property. So, we are going to run through some of the most frequently asked questions below.
The best pest repeller is the one that works for your home situation and the pest you’re trying to repel. We believe that sprays and powders work best for bugs, while ultrasonic repellers are better for rodents. Just make sure that any pest repeller you choose won’t negatively impact your children, pets or garden.
As far as plant-based formula repellents go, peppermint is the star of the show. Thyme, citronella, sage and lavender all have their uses and are much better smelling than most chemical repellents. But, without a doubt, peppermint is an essential oil of choice for dealing with common pests. It’s ideal for placing around the doors, windows and other entry points of your humble abode, ready to fight off spiders, moths, fleas and other unwanted critters. To top it off, you can also use peppermint oil to effectively deter larger creatures, such as mice and roaches.
To prevent rodents from entering your space, we recommend using a pest repellent with a strong smell. Mice and rats have a very strong sense of scent, so essential oils, like peppermint oil, cinnamon oil and pine oil, are all great options. Also, pest repellers which include cayenne pepper or ammonia should also work. However, if you don’t want to use a spray, we also recommend ultrasonic repellents, so long as the rodents haven’t already entered your home.
There are two types of plug-in repellers, namely those that rely on ultrasound and those that create an electromagnetic field. The first type is seemingly more effective than the second, according to several scientific studies. However, ultrasonic repellents will only function if the pests have no reason to enter your space. If they have already built nests or discovered a reliable food source, they are capable of ignoring very loud ultrasounds. On the other hand, electromagnetic pest repellents create a very small field that’s not much larger than the average lightbulb. Therefore, you would need a lot of these pest repellents in your home to make a difference, but they can deter some bugs, like spiders and earwigs. With this in mind, we’ve included very few electromagnetic pest repellents below.
