What is a rat repellent?

Rats. Even the sound of the word is awful. If you have an issue with rodents, it’s critical for you to rid your home of these pests. They carry several serious diseases. Including Leptospirosis, Rabies, The plague and Hantavirus Pulmonary Syndrome.

These animals are not only dangerous from a human perspective, but they’re destructive too. 

They are a significant pest in agriculture, damaging about 20 percent of global products . That’s part of the reason why prevention is so desirable. 

They can cause significant damage to your home over time. And the problems will continue to mount with this prolific breeder. Prevention, therefore, is easier to manage than ridding your home of an infestation. That’s where repellents come into play.

If you have a rat issue but do not want to use poison or other lethal measures to eradicate the population, you need a natural outdoor rat repellent. Or, to be more specific, you are going to need a combination of tactics to repel or prevent a backyard rat colony.

Killing them off is, of course, the fastest and surest method for getting rid of outdoor rats, but there are several reasons you may not want to go this route. 

One of the main reasons folks do not want to resort to lethal methods is because they want the rats gone, but that does not mean that they want them dead. They want them to move on and live somewhere farther away from the outdoor living areas where their children play and they entertain guests.

Another reason to not use lethal methods is that they may affect other animals that are welcome in your yard. For example, squirrels or chipmunks may be killed by baited traps or may consume the rat poison and die. 

It is also possible that your dog, your cat or a raptor might catch a poisoned rat and become ill or die.

At the very least, this likely means that you will have to endure horrible smells coming from under your deck until the bodies decompose. In other cases, this could mean fishing dead rats out of your swimming pool or hot tub, or it could mean collecting rat carcasses littering your yard.

While you may not want to use lethal methods to rid your yard of rats. There are reasons to take steps to ensure that a rat colony does not become established in your backyard. For example, rats carry fleas that can transfer to your dogs or cats and that sometimes carry diseases. Plus, the rats, themselves, carry a handful of diseases that can be transferred to humans or other animals.

There is also the fact that most folks just do not like the idea of rats running across their outdoor dining tables. Or the counters in their outdoor kitchen. Pooping on their patio cushions or racing across the yard in the middle of a dinner party.

So, here’s the deal: rats are pretty simple (but rather smart) creatures that mostly want food, water and shelter. If they are hanging out in your backyard, that is because you are unwittingly providing them with these basic needs.

To reclaim your outdoor living areas, you need to encourage your current rodent residents to move on to more hospital accommodations. Also discourage new rats and mice from making themselves at home in your yard.

What Are Rat Repellents?

Rat repellents are just what the name implies. They prevent rodents from entering your home. The concept is as old as time itself. You’ll find these products in several forms including:


The key theory behind most liquid based rat repellent products is that it will fill the air in and around where the rats are causing the problem. Making them so uncomfortable that they will want to go somewhere else. 

These scents can range from actual predator urine to chemicals that mimic predator urine scent. These smell very strongly and are even unpleasant to the human nose. Beyond possibly raising the fear of a predator, or making the animal uncomfortable, repellents are not usually poisonous and cannot have a more serious impact than that. Which is why many people don’t have great success using these kinds of products. 

Chemical Rat Repellent

Some of the most common repellents on the market are chemicals. One of the most popular base substances for these repellents are mothballs, or naphthalene. 

The problem with this is that naphthalene is toxic, and fumes can give some people headaches. But there is no evidence, even on a small scale, that mothballs can be effective. 

Ammonia is another toxic chemical with a strong scent that is said to be a repellent. While many more modern products do not want to repel humans along with the rats, so there are plenty of products based on a peppermint oil base too.

Audio And Ultrasonic rat repellent

While chemicals usually affect the noses of the rats, the audio devices are said to be so unpleasant for rats that they will immediately leave the area. They want to get out of range of the high pitched squeal which is outside the hearing range of people. These are to cause a painful noise in the rat’s ears, which then drives them away. 

There are plenty of different types of audio devices available, and these range from relatively cheap devices that are battery powered through to more complicated systems.

Home Remedies as rat repellent

While chemical and liquid repellents may struggle to get rid of the rats for you, there are also home remedies that are said to do the job, but in many cases, these will have a similar success rate.

Human hair is said to be one thing that the rats really cannot stand, while mothballs is also a common repellent, and even the disinfectant toilet cakes are said to drive the animals away. The reality is that they are cheaper than the chemicals, but have similar results and really just need to be forgotten so that the rat problem can be appropriately dealt with.

 Why Don’t Traps Work?

In order for a rat trap to be truly effective and to get rid of these pest animals, there is a simple equation that needs to be met. The key to a good trap is that it needs to be too painful or uncomfortable for the rat to stay in the area, despite all of the positive features such as food sources and nesting sites. 

In most cases, the positive features are more important to the rat than the trap, meaning that it won’t want to leave and is likely to stay around to enjoy the features on offer from your property.


Electronic devices/ Ultrasonic Devices  – WHAT DETERRENT WORKS? 

Rat Repellent – There are many different ways that people can use if they are looking to get rid of rats that have invaded an attic, shed, yard or other part of a property. 

But one of the best available products is an ultrasonic rat repellent

The advantage of these products is that you can use it in areas where poisons are inappropriate such as food prep places or playgrounds. They are a viable alternative if you have pets too since many are host-specific. Your dog or cat is unlikely to notice some at all. 

Repellents will be able to drive away the animal by making it so unpleasant for the rat to continue to live in the area, that it will have to leave to find a new home. 

What Is the Correct Way to Use Ultrasonic Devices?

We suggest using rat repellents in conjunction with other pest control measures. That’s due primarily to the nature of these rodents. They are opportunistic, adaptable, and keenly aware of their environment. They have an excellent sense of smell too. That means that they’ll notice new scents and things around them.

You may have to experiment with using rat repellents in different areas around your home to find the most effective places to use them. Remember that the best way to repel rodents is to prevent them from entering in the first place.

Follow the label directions as indicated. You may see specific guidelines for use. Often, they provide suggested coverages for electronic devices, precautions, or recommended timelines to reapply them in the case of liquids and pellets.

Some items include suggested usage timelines that we recommend you follow to assess their effectiveness thoroughly. Mind the length of any warranties too, especially if you’re planning on using them for a lengthy period.

What Should I Look for in a Rat Repellent?

Our advice is to seek out products with a satisfaction guarantee. Then, put them to the test to see if they work as intended. Make sure to review any terms and conditions. We also recommend following any guidelines related to non-targeted animals such as pets.

The value of these repellents is that they offer another way to avoid a rodent infestation and are safer than poisons. Most of the latter are harmful to pets even if they aren’t the intended target.


Rats can cause significant damage to your home over time. And the problems will continue to mount with this prolific breeder.
