How to Use Bleach to Kill Rats

If you have a rat infestation in your home, you know how frustrating and overwhelming it can be. Not only can rats carry diseases, but they can also cause damage to your property.

How to Use Bleach to Kill Rats

While there are many ways to get rid of rats, one method gaining popularity is using bleach to kill them. Bleach is an effective way to get rid of rats, but it should be used cautiously. In this article, we will discuss how to use bleach to kill rats.

Can You Use Bleach to Kill Rats?

When it comes to unwanted house guests, rats are pretty high on the list. These pesky rodents can cause damage to your home and spread disease, so it’s natural to want to get rid of them as quickly as possible. But can bleach do the trick?

While bleach is known for its disinfecting properties, it’s not effective in killing rats. In fact, it’s not even safe to use bleach as a rodent repellent, as the fumes can harm humans and animals. Instead, it’s best to use more humane and effective methods, such as traps or calling in a professional pest control company.

Why Should You Use Bleach to Kill Rats?

When it comes to rat infestations, the last thing you want is to use a method that only scares them away temporarily. That’s where bleach comes in. Not only is it a powerful disinfectant, but it’s also a potent rat killer. Rats are attracted to certain smells, and they can’t stand bleach.

By pouring or spraying bleach in the areas where rats tend to roam, you’ll not only be ridding your home of their musk but also greatly diminishing their population. Plus, bleach is a safer alternative than toxic rat poisons or traps, which pose a risk to humans and other pets. It’s time to say goodbye to the pesky rats and hello to the clean, hygienic home you deserve.

The Ultimate Guide on How to Use Bleach to Kill Rats

1. Understanding How Bleach Kills Rats

Before effectively using bleach to kill rats, it’s important to understand how it works. Bleach is a powerful disinfectant that contains sodium hypochlorite. When rats ingest bleach, it reacts with their stomach acid and creates a toxic gas that is lethal to them. Bleach can also effectively reduce the smell of rats, which can help prevent future infestations.

2. Setting Up Your Traps

Setting up traps is an essential part of using bleach to kill rats. You can use a few different types of traps, including snap traps, glue traps, and live traps. To effectively use bleach, you must set up the traps in areas where rats are known to frequent.

Once you have caught a rat, place it in a container with a lid that can be sealed tightly. This will prevent the toxic gas from escaping and harming other animals or people in your home.

3. Preparing the Bleach Solution

Preparing a Bleach Solution

When preparing a bleach solution, it’s important to take safety precautions. First, make sure to wear gloves and protective clothing to avoid contact with the bleach. Next, dilute the bleach with water.

The recommended ratio is 1 part bleach to 10 parts water. This will ensure that the bleach is strong enough to kill the rat but not so strong that it poses a risk to other animals or people in your home.

4. Administering the Bleach

Once you have caught a rat and prepared your bleach solution, it’s time to administer it. Pour the bleach solution over the trapped rat, covering it completely. It’s important to note that this method may take some time to work.

It can take up to 24 hours for the rat to die from the toxic gas produced by the bleach. After 24 hours, dispose of the dead rat and thoroughly clean the area to prevent future infestations.

5. Additional Tips for Using Bleach to Kill Rats

Always Wear Protective Clothing and Gloves

While bleach can be an effective way to get rid of rats, taking additional precautions is important to ensure your safety. Always wear protective clothing and gloves when handling bleach, and dispose of dead rats safely and responsibly.

Additionally, it’s important to seal up any holes or entry points in your home to prevent future infestations.

6. Alternative Methods for Rat Control

If using bleach to kill rats is not a suitable option for you, there are alternative methods for rat control. These include using humane traps and releasing the rats in a nearby wooded area, hiring a professional pest control service, or using natural deterrents such as peppermint oil or ultrasonic devices.

7. Prevention is Key

Lastly, it’s important to take preventive measures to avoid future rat infestations. This includes keeping your home clean and clutter-free, sealing up any holes or cracks, and storing food properly to avoid attracting rats.

5 Considerations Things When You Need to Use Bleach to Kill Rats

1. Safety Precautions

When using bleach to kill rats, it is important to take safety precautions to protect yourself and your family. Wear protective clothing such as gloves, long sleeves, and a face mask when handling the bleach.

Make sure you are in a well-ventilated area and keep children and pets away from the area. Additionally, never mix bleach with other cleaning products, as this can create dangerous fumes.

2. Choose the Right Bleach

It is important to use the right type of bleach when trying to kill rats. Regular household bleach contains 5% sodium hypochlorite, which is not strong enough to be effective against rats. Instead, use a stronger solution such as chlorine bleach or industrial-strength bleach, which contains 10-15% sodium hypochlorite.

3. Apply the Bleach

Once you have chosen the right type of bleach, it is time to apply it. Pour the solution into any holes or cracks where you suspect that rats may be entering your home or garden.

Spraying the Solution Directly Onto Areas Where You See Rat

Spraying the solution directly onto areas where you see rat droppings or nests is also possible. Make sure that you cover all areas thoroughly for maximum effectiveness.

4. Dispose of Dead Rats Properly

After applying the bleach, it is important to dispose of any dead rats properly to avoid spreading disease or attracting scavengers such as birds or other animals. Place dead rats in sealed plastic bags and dispose of them in an outdoor trash bin at least one mile from your home or garden if possible.

5. Clean Up Thoroughly

Finally, make sure that you clean up thoroughly after using bleach to kill rats to prevent contamination and protect your health and safety. Wear protective gear while cleaning up any spilled solution and discard any materials used during application, such as gloves, masks, rags, etc., in sealed plastic bags before disposing of them properly.

5 Benefits of Use Bleach to Kill Rats

1. Kills Rats Quickly

 It Can Effectively Kill

One of the main benefits of using bleach to kill rats is that it can effectively kill them quickly. Bleach is a powerful disinfectant and, when used properly, can be an effective way to get rid of rats in a home or business.

When applied directly to the rat or its nest, it will kill the rat within minutes. Bleach can also be used to clean up any messes left behind by the rats, such as droppings and urine.

2. Inexpensive

Another benefit of using bleach to kill rats is that it is relatively inexpensive compared to other methods of pest control. A small bottle of bleach can typically be purchased for less than $5 and will last for several applications. This makes it an ideal option for those who are on a tight budget but still want to get rid of their rat problem quickly and effectively.

3. Easy To Use

Using bleach to kill rats is also easy to do since all you need to do is mix some bleach with water and pour it into areas where you have seen rats or their nests. It is important, however, that you use caution when applying the solution as it can cause skin irritation if it comes into contact with your skin or eyes. Additionally, bleach should not be used around pets or children as they could become ill if exposed to the fumes from the solution.

4. Non-Toxic

Unlike other types of pest control products that may contain toxins or chemicals that are harmful to humans and animals alike, bleach is non-toxic and poses no health risks when used correctly.

Additionally, since bleach breaks down quickly after application, there are no long-term environmental impacts from using it to eliminate rodents from your property.

5. Effective Against Other Pests

Using Bleach Can Also Help Eliminate Other Pests

In addition to being an effective way of killing rats, using bleach can also help eliminate other pests, such as cockroaches, ants, fleas, and bedbugs, from your home or business premises as well.

As with rats, you should make sure that you apply the solution carefully so that it does not come into contact with your skin or eyes, and take care not to use too much as this could damage surfaces in your home or business premises if left on for too long.

4 Common Mistakes People Make When Trying to Use Bleach to Kill Rats

1. Using Too Much Bleach

One of the most common mistakes people make when using bleach to kill rats is using too much. It’s important to remember that bleach is a powerful chemical and can be toxic if used in large quantities.

When using bleach to kill rats, it’s important to use only enough to cover the area where the rat has been seen or where droppings have been found. If more than this is used, it can be dangerous for humans and pets, as well as potentially damaging surfaces in the home.

2. Not Taking Precautions

Another mistake people often make when trying to use bleach to kill rats is not taking proper precautions. Before attempting to use any type of chemical, it’s important to read all instructions carefully and take necessary safety measures such as wearing gloves and a face mask. In addition, it’s important to keep children and pets away from the area while using bleach or any other chemicals.

3. Not Cleaning Up Afterwards

Can Be Harmful if Not Cleaned Up Properly

Using bleach may seem like an effective way to get rid of rats, but it’s also important to remember that it can leave behind residue, which can be harmful if not cleaned up properly afterward. After using bleach, all surfaces must be thoroughly rinsed with hot water and soap before being dried completely with a clean cloth or paper towel.

This will help ensure that no residual chemicals are left behind, which could pose a health risk for humans or animals in the home.

4. Not Taking Other Measures To Prevent Infestation

Finally, another mistake people often make when using bleach to kill rats is not taking other measures, such as sealing off entry points into their homes and removing food sources such as garbage cans or pet food containers from around the outside.

These steps are essential for preventing future infestations of rodents. They should always be taken in addition to any chemical treatments used to ensure complete control over rat populations in your home or business premises.


Dealing with a rat infestation can be a stressful and frustrating experience, but using bleach to kill rats can be an effective way to get rid of them. By following the steps outlined in this article, you can safely and effectively use bleach to kill rats in your home.
