What you’ll learn from this Guide:

What is a Rat Repellent and Why Do I Need One?

A rat repellent is exactly what it sounds like – something that keeps rats away. It makes the environment undesirable for rats. Repellents have a few advantages over other types of rat control. A rat repellent would prevent you from having to kill the rodents. Pest control companies can be a lot more expensive than rat repellents. Traps, as stated before, may simply not work. Another thing to consider is that if you wait until rats are in your home to try to get rid of them, they may cause considerable damage while they are there.

How Does a Rat Repellent Work?

Rat repellent (or deterrent) works by either taste, smell, or sound aversion. Thus rat repellents can be represented in either substances that avert rats by smell and taste or devices that use sound to make rats go crazy and leave the treated area.

What to Consider When Buying?

Environmental Protection Agency (EPA) doesn’t regulate the use of rat repellents and doesn’t require their efficacy testing. While botanicals (natural repellents, that we are going to discuss further) are considered safe by the EPA, there’s little data available on their effectiveness. I’ve found the only study that specifically addressed the efficacy of natural repellents was conducted outside of the United States, in Thailand, and primarily concerned the following substances: wintergreen oil, chili, peppermint, bergamot, and geranium oils. The researchers concluded that the oils used were effective, but indicated that more studies and research were necessary. The same situation is with the electronic repellents: there are not reliable studies available to prove their true effectiveness.

So whenever buying a repellent, consider that there’s no scientific data on its efficacy. But we still recommend it as a preventative measure.

Types of Rat Repellents and How They Work

I will introduce you to two types of rat repellents: natural and electric repellents. Natural repellents are things that grow naturally that rats try to avoid. An example of an electric repellent would be an ultrasonic repellent. The general way that both of these repellents work is by giving of a smell or sound that drives rats crazy and out of the door.

In the next section, I will cover some relatively effective natural rat repellents as well as some electric repellents worth buying.

Natural Rat Repellents

Natural rat repellents could include things like essential oils or botanicals (plant-based repellents). Natural repellents are preferable to other types because they aren’t toxic to people or pets. Here are three really good natural rat repellants you may be interested in.

Essentially KateS Peppermint Essential Oil

Rats can’t stand peppermint oil, so it is one of the best essential oils to use as a repellent. It has a strong scent and you can mix it with water to spray around your house. Or you put a few drops of peppermint oil on cotton balls, place them in water for freshness, and put them whenever you’ve seen rats or their excrements.

  • It has a strong, woodsy undertone in the scent so it is questionable if this is 100% pure peppermint oil.

Ultrasonic Rat Repellents

Ultrasonic rat repellents are electronic devices that emit an ultrasound at a high frequency that deters pests. The sound is inaudible to the human ear, but pests can hear it and the sound disturbs them enough to make them stay away.

There is a lot of debate about how effective ultrasonic repellents are, but some of them actually seem to work fairly well. Here are two of the best that I’ve seen on the market.

Pest Venator Ultrasonic Mouse Repellent

Pest A Cator Plus 2000 Electromagnetic/Ultrasonic Rodent Repeller for Larger Areas

The Pest Venator Ultrasonic Mouse Repellent is really a system–it comes with four inconspicuous devices that can cover up to 3,600 square feet (a single unit covers an area of 260 sq.ft). The frequency doesn’t bother pets but will drive rats crazy. According to the manufacturer, you should be rat-free in three to four weeks when you use them as directed.

  • These devices are very easy to use – just basically plug ‘n play.
  • It comes with an E-book called “How to Get Rid of Rats” written by the biologist Michael Potter that you can use as a guide to making your home rodent-free.
  • One customer complained that when she plugged in devices, there would be one that she could hear. According to scientific data, a very small number of people and small children have an extremely sensitive hearing. So, the suggestion is to put it in the garage.

T3-R Triple High Impact Rodent Repeller

T3-R Triple High Impact Mice, Rat, Rodent Repeller

Unlike the previous system, this is a one-device system. It has what the manufacturer calls a Triple Attack technology. The device features three speakers, each with a different sound/frequency so that it is very effective against all kinds of rodents including squirrels.

According to the manufacturer, rats will be gone within 16 days. The gadget comes with 6 ft plug in cord. Good for use indoors and outdoors, as it is waterproof. Covers an area up to 6000 sq.ft

  • One device does it all so you don’t have to fumble around and waste time placing multiple devices.
  • This product can be used outside in a covered location as long as you have electricity. The description says waterproof, but we still advise you cover the
  • Unlike the Pest Venator, this ultrasonic repellent stands on its own and has a power cord that could get in the way.
  • The warranty information isn’t available. It isn’t clear how to contact the company for a repair or refund.

Pros & Cons of Using Rat Repellents

  • You won’t be putting poison all over your home, which could affect the health of your curious children and pets.
  • You won’t have to worry about cleaning up dead rodents from your home.
  • Rodents won’t be in there causing damage and spreading germs while you’re trying to trap them/poison them/trick them.
  • Ultrasonic repellents don’t require you to constantly reapply them. You just plug them up and leave them. It’s a hassle-free solution.
  • You will also get rid of other types of pests at the same time like spiders.
  • Can cover a large area (some devices, according to manufacturers, can cover as much as 6,000 ft)
  • There are a lot of faulty products on the market that don’t work and give the others a bad name.
  • While most natural repellents do smell pleasant, it really is a matter of personal taste. So you have to deal with a lot of different, strong scents that you or your family may or may not like.
  • Once the repellent runs out, or the ultrasonic repellent is unplugged, the rats may come back.
  • Doesn’t come cheap
  • Not enough scientific evidence to prove their effectiveness

If the repellent is a liquid or spray, yes you will have to reapply it, but only if it is used outdoors.

How do rat repellents work?
They work by irritating the rodents so much that they just want to leave. This is done either through scent or sound.

What are the rat repellents for cars? Rat repellents for car engines?
You can use the same rat repellents for vehicles as you do for home. Most of the ultrasonics will need to be plugged up so they may not be suitable for a vehicle unless it’s an RV or something similar. However, there are special ultrasonic repellents that can be used in cars, they are usually battery operated and can be placed directly under the hood.

Growing mint in your yard is a way to repel rats. But it’s a very short-term solution. Also, many of the repellents in the list above can be used outdoors.

Which rat repellent is best for office?

Tips and Lifehacks for Using Rat Repellents


Try not to use ultrasonic devices in rooms with a lot of soft fabrics. They may absorb the frequency and the device won’t work as well as it should. The main rule of ultrasonic effectiveness: If there is no soft furniture, curtains, carpets and other soft things in the room, then the result will be better — ultrasound can fill all the space due to multiple reflections from walls, ceiling, and floor.

Tip #2

Although rat repellents can be used outdoors, the point is to keep rats out of your home, not out of outside.

Tip #3

You may not want to use repellents with traps. After all, the trap will attract the rat while the frequency repels the rat. This may not work out to your advantage the way you think it will.


Having rats in your home is really disturbing and getting rid of them can be hard. Rat repellents will get them out and keep them out and you won’t have to lift a finger. On top of that, your home can remain chemical and poison free. While rat repellents may not be the strongest remedy or technology right now, as time and research progresses, these solutions will become better and better. Hopefully the list above provided you with a good starting point in your search for a good rat repellent. Now you are that much closer to a rodent free home!
