Killing rats with salt is a popular method of pest control. Rats are known to carry diseases and cause damage to property, making them a nuisance that needs to be dealt with.

Salt is an inexpensive and readily available substance that can be used to kill rats, making it an attractive option for those looking for a DIY solution.

The process of killing rats with salt involves luring the rats to a bait that has been mixed with salt.

Once the rats consume the bait, the high levels of sodium in the salt will cause dehydration, leading to their eventual demise.

While the method may seem simple, it is important to note that it may take up to 24 hours for the rat to die after consuming the salt.

Additionally, it is crucial to ensure that the bait is placed in a location where pets and children cannot access it.

While killing rats with salt may seem like a quick and easy solution, it is important to consider the potential risks and drawbacks.

For instance, the method may not be effective in eliminating a large infestation, and there is a risk of the rats dying in hard-to-reach areas, leading to unpleasant odors and the attraction of other pests.

Moreover, the use of salt may harm other animals and plants in the area, making it a less-than-ideal solution in some cases.

Why Use Salt to Kill Rats?

When it comes to getting rid of rats, there are many methods to choose from. One method that has gained popularity in recent years is using salt to kill rats. But why use salt to kill rats?

In this section, we will explore the effectiveness and safety of using salt to kill rats.

The Effectiveness of Salt in Killing Rats

Salt is a natural desiccant, which means it has the ability to absorb moisture from its surroundings. When a rat ingests salt, it can cause severe dehydration, leading to death.

However, it’s important to note that salt alone may not be enough to kill a rat. Rats are intelligent creatures and may avoid eating food that has been laced with salt.

Therefore, it’s recommended to mix salt with other ingredients to make it more appealing to rats.

The Safety of Using Salt to Kill Rats

Using salt to kill rats may seem like a humane and safe method compared to using poison or traps.

However, it’s important to use caution when handling salt as it can be harmful to humans and pets if ingested in large quantities.

Additionally, salt may not be effective in killing all types of rats, and it may take several days for the rat to die, which can lead to unpleasant odors and hygiene issues.

In conclusion, using salt to kill rats can be an effective and safe method when used correctly.

However, it’s important to take precautions when handling salt and to use it in combination with other ingredients to increase its effectiveness.

How to Use Salt to Kill Rats

Rats can be a nuisance and cause significant damage to property. If you are dealing with a rat infestation, you might be wondering if there are any effective ways to get rid of them.

One method that has been suggested is using salt to kill rats.

Here’s how to do it:

Preparing the Salt Mixture

To prepare the salt mixture, you will need to gather a few supplies. These include:

  • Salt (table salt or Epsom salt)
  • Flour
  • Sugar
  • Baking soda
  • Water
  • Bowl or container
  • Spoon or mixing tool

To make the mixture, combine equal parts flour, sugar, and salt in a bowl or container. Add a small amount of baking soda and mix everything together.

Slowly pour in water while stirring until the mixture becomes a thick paste.

Placing the Salt Mixture in Strategic Locations

Once you have prepared the salt mixture, you will need to place it in strategic locations where rats are likely to visit. This can include areas such as:

  • Near rat holes or burrows
  • Along walls or baseboards
  • Near food sources
  • In areas where rats have been spotted before

To make the mixture more appealing to rats, you can add a small amount of food or bait to it. Once you have placed the mixture in the desired locations, wait for the rats to consume it.

It is important to note that using salt to kill rats is not a guaranteed method, and there are potential risks involved.

Salt can be harmful to other animals and pets, and it can also damage plants and soil.

Additionally, rats may become wary of the salt mixture if they detect it and avoid consuming it.

In conclusion, using salt to kill rats can be a cost-effective and natural method of pest control.

However, it should be used with caution and only as a last resort after other methods have been tried.

If you are unsure about using salt to kill rats, it is best to consult with a pest control professional for advice.

Other Methods of Rat Control

There are several other methods of rat control that can be used in addition to using salt. These methods include traps, poisons, and natural repellents.


Traps are a common method of rat control and are typically used in homes and businesses. There are several types of traps available, including snap traps, glue traps, and live traps.

Snap traps are the most common type of trap and work by using a spring-loaded bar to kill the rat when it takes the bait.

Glue traps are another option and work by trapping the rat on a sticky surface.

Live traps are a humane option and work by trapping the rat in a cage, which can then be released into the wild.


Poisons are another method of rat control and are typically used in areas where traps are not effective or practical.

There are several types of poisons available, including anticoagulant poisons and non-anticoagulant poisons.

Anticoagulant poisons work by preventing the rat’s blood from clotting, which eventually leads to death.

Non-anticoagulant poisons work by causing the rat’s nervous system to shut down, which also leads to death.

It is important to use poisons carefully, as they can be harmful to humans and pets if ingested.

Natural Repellents

Natural repellents are a non-toxic method of rat control and work by using scents and flavors that rats find unpleasant.

Some common natural repellents include peppermint oil, mothballs, and ammonia.

Peppermint oil can be applied to cotton balls and placed in areas where rats are present.

Mothballs can be placed in areas where rats are present, but should not be used in areas where humans or pets are present.

Ammonia can be mixed with water and used to clean areas where rats have been present.

While natural repellents are generally safe, they may not be as effective as traps or poisons and may need to be used in conjunction with other methods of rat control.


In conclusion, killing rats with salt is a safe and effective method for eliminating these pesky rodents.

It is a humane alternative to traditional rat poisons and traps. However, it is important to take preventative measures to keep rats from returning.

The advantages of using salt to kill rats include its availability, affordability, and ease of use. Salt can be found in most households and is much cheaper than commercial rat poisons.

It can be mixed with other ingredients to make bait or used as a solution to spray in areas where rats are present.

One disadvantage of using salt to kill rats is that it may take longer to work than other methods. Rats may take up to 24 hours to die after ingesting salt.

Additionally, if the rat does not have access to water, it may take longer for the salt to take effect.

Overall, using salt to kill rats is a viable option for those who want to avoid using harsh chemicals or inhumane traps.

However, it should be used in conjunction with other preventative measures, such as sealing up entry points and keeping food sources out of reach.
