5 Salt Mixtures for Bed Bug Control: What Works and What Doesn’t

Bed bugs can be a persistent and frustrating problem. Whether you’ve just discovered them in your home or have been dealing with them for a while, you’re probably looking for effective ways to get rid of them.

Some people swear by using salt as a home remedy to kill bed bugs. However, does it really work?

In this article, we’ll explore how salt works against pests, why salt is ineffective against bed bugs, and other mixtures that may help you get rid of these pesky pests. How Salt Works Against Pests:

Salt works by dehydrating the bodies of pests.

When salt comes into contact with a pest’s body, it absorbs moisture, causing the pest’s body to dry out and eventually die. This is because salt has the ability to absorb water from its surroundings, leaving the pests without the moisture they need to survive.

Salt’s Ineffectiveness Against Bed Bugs:

Unfortunately, salt is ineffective against bed bugs. Bed bugs have a hard outer shell that protects their soft organs.

Salt can’t penetrate this shell, so it doesn’t dehydrate the bugs. Even if the salt were able to penetrate the shell, it wouldn’t be toxic enough to kill the pests.

Bed bugs are more resilient than many other pests, so using salt as a remedy is unlikely to work. Other Mixtures Including Salt:

While salt may not be effective against bed bugs, there are other mixtures that may help get rid of these pests.

Two of the most commonly recommended mixtures are baking soda and borax. Baking soda can be sprinkled on carpets and upholstery, left for a few hours, and then vacuumed up.

Borax can be mixed with water and sprayed on problem areas. Both of these substances are able to penetrate the outer shell of bed bugs and dehydrate them from the inside out.

Another mixture that may help is diatomaceous earth. This substance is made from the fossilized bodies of tiny aquatic organisms called diatoms.

When bed bugs come into contact with diatomaceous earth, the substance scratches their outer shell, causing them to become dehydrated and die. Like baking soda and borax, diatomaceous earth is able to penetrate the outer shell of bed bugs and kill them from the inside out.

Effects of Salt on Bed Bugs:

While salt itself is ineffective against bed bugs, there are a few ways in which it can still be useful. For example, if you sprinkle salt around the perimeter of your bed or other problem areas, it may make it more difficult for bed bugs to get to you.

Salt won’t kill the bugs, but it can make them uncomfortable and motivate them to seek out other areas to infest. Additionally, if you have a saltwater solution (salt dissolved in water), you can spray it directly on the bugs.

While the salt won’t dehydrate them, it may cause discomfort and motivate them to flee. Salt’s Effectiveness on Other Pests:

While salt may not be effective against bed bugs, it can be useful for other pests.

For example, salt can be used to kill slugs and snails. When salt comes into contact with these pests, it absorbs moisture from their bodies and causes them to dehydrate.

Additionally, salt can be used to absorb moisture from many different pests, including cockroaches and ants. Conclusion:

While salt may be a common home remedy for many different pests, it’s important to understand that it’s not effective against bed bugs.

While salt can be useful in deterring bed bugs, it won’t kill them. If you’re dealing with a bed bug infestation, it’s best to use other mixtures such as baking soda, borax, or diatomaceous earth.

By understanding how salt works against pests and why it’s ineffective against bed bugs, you can better protect your home and family from these pesky pests.

Use of Salt Mixtures Against Bed Bugs

Bed bugs are a persistent problem that requires an effective solution, and while salt may be one of the most commonly recommended home remedies, it’s not the best option. Salt may be useful for deterring bed bugs, but it’s ineffective at killing them.

However, mixing salt with other substances may create a self-made cleaning tool that can help deter bed bugs. Let’s explore some of the salt mixtures that have been suggested to help control bed bugs.

Mixing Salt with Baking Soda and Borax:

Mixing salt with baking soda and borax is one of the most frequently suggested remedies for bed bugs. While this mixture is not toxic to humans, it’s also ineffective at killing bed bugs.

The mix of these substances can create a thick layer, which can create an inhale-able vapor that may lead to irritation of the lungs. In some cases, this can even lead to respiratory distress, especially in people with pre-existing conditions.

Therefore, it’s important to handle this mixture with care and avoid inhaling the vapor when using this combination. Diatomaceous Earth vs.

Salt Against Bed Bugs:

Diatomaceous earth is another substance that has been suggested for bed bug control. Like salt, diatomaceous earth works by dehydrating the bugs through its ability to absorb oils and liquids.

It’s important to note that diatomaceous earth is better equipped to combat these bugs, as it is a finely ground powder that can work its way into the crevices of beds and upholstery. Unlike salt, it can penetrate the bed bugs exoskeleton and cause dehydration in their inner organs, effectively killing them.

However, it’s also important to note that diatomaceous earth can be hazardous when inhaled. It’s essential to wear a mask when applying and keep it away from children and pets.

Epsom Salt and its Ineffectiveness:

Another salt mixture that has been suggested for bed bug control is Epsom salt. This magnesium sulfate compound is not recommended for bed bug control and can be hazardous if ingested.

It’s important to note that while Epsom salt may have some beneficial properties, when it comes to bed bugs, it’s not an effective treatment. Simply put, Epsom salt is a wasteful option for bed bug control that fails to achieve a satisfactory death rate among bed bugs.

Saltwater’s Ineffectiveness Against Bed Bugs:

While saltwater is known for its antiseptic properties, it’s ineffective at controlling bed bugs. Like salt, saltwater merely causes discomfort to bed bugs by creating an itching sensation and inflammation when it comes in contact with the skin.

However, bed bugs have the ability to hide and can avoid contact with saltwater, making it an ineffective solution. Saltwater may be an irritant for bed bugs, but it doesn’t offer any real benefits for individuals struggling with an infestation.


In conclusion, salt may be a commonly suggested home remedy for bed bug control, but it’s not an effective solution. Despite salt’s drying capabilities, it can’t penetrate the thick outer shell of bed bugs and dehydrate them completely.

Enhanced mixtures of salt with baking soda and borax may help, but they still aren’t a powerful enough solution to control bed bugs. Although diatomaceous earth may be a useful tool in combating bed bugs, it should be used with caution.

It’s essential to handle all bed bug control measures with care and use a proven insecticide. Hiring a professional pest control company is an effective way to remove these nuisance bugs quickly and efficiently.

Continue reading this blog for more facts and information on bed bugs and effective pest control solutions. In conclusion, bed bugs can be a worrisome problem, and while salt is a commonly suggested remedy for their control, it’s not as effective as many people believe.

Salt can only create discomfort for these bloodsucking bugs, but it cannot kill nor control their population. Diatomaceous earth, baking soda, and borax are more effective methods, but it’s essential to handle all bed bug control measures with caution.

Insecticides are the best option for removing bed bugs immediately and completely. By considering these facts, using proven measures and taking timely action, we can effectively rid our homes of these pesky invaders and enjoy our surroundings in peace.
