Does Salt Kill Bed Bugs?

by | Jun 7, 2023 | 0 comments

When faced with a bed bug infestation, many people seek natural remedies as a first line of defense. One such popular remedy is salt. The theory behind using salt as a bed bug killer is that it dehydrates the insects, leading to their demise. In this article, we will explore the effectiveness of salt for bed bug control and why it ultimately falls short in eradicating these pests.

1. Introduction

Bed bugs are resilient pests that can cause sleepless nights and frustration. It’s no wonder individuals are eager to find natural solutions to combat these insects. One such solution that has gained attention is the use of salt. However, it’s important to understand why salt is ineffective for killing bed bugs and controlling infestations.

2. The Theory Behind Salt as a Bed Bug Killer

The theory behind using salt for bed bug control is based on the belief that salt can dehydrate and kill these pests. According to this theory, salt is believed to absorb moisture from bed bugs, leading to their eventual death. Various methods have been suggested, including sprinkling salt directly on infested areas or creating salt barriers to prevent bed bugs from accessing certain areas.

3. The Ineffectiveness of Salt for Bed Bug Control

Despite the appealing concept, scientific evidence does not support the effectiveness of salt as a bed bug killer. While it is true that salt has drying properties, bed bugs have evolved to withstand harsh conditions, including dehydration. Their bodies are designed to retain moisture, allowing them to survive for extended periods without feeding.

Furthermore, bed bugs have a natural ability to detect and avoid substances that could be harmful to them. They can sense the presence of salt and will actively avoid areas where salt has been applied. This makes it even more challenging for salt to contact the bugs directly, rendering it ineffective as a control method.

4. Potential Drawbacks of Using Salt for Bed Bugs

In addition to its ineffectiveness, using salt for bed bug control can have drawbacks. Excessive salt application on carpets or furniture can lead to discoloration and damage. Salt particles can also clog vacuum cleaners, affecting their performance and potentially causing damage. Moreover, salt may not adhere well to certain surfaces, making it easy for bed bugs to navigate around the salt barriers.

5. Proven Methods for Effective Bed Bug Control

When dealing with a bed bug infestation, it is important to rely on proven methods for effective control. Professional pest control services offer expertise and knowledge in dealing with these resilient pests. Some effective methods include:

  • Heat treatments: Utilizing specialized equipment to raise the temperature of infested areas, effectively killing bed bugs and their eggs.
  • Insecticides: Using approved insecticides specifically formulated to target and eliminate bed bugs.
  • Steam cleaning: Applying high-temperature steam to infested areas, can effectively kill bed bugs and their eggs.

6. Importance of Seeking Professional Assistance

While natural remedies may seem appealing, they often fall short for complete bed bug eradication. Seeking professional assistance is crucial, especially for severe infestations. Pest control experts have the knowledge, experience, and access to effective treatments that can eliminate bed bugs efficiently and thoroughly. They can assess the extent of the infestation, customize a treatment plan, and provide guidance on preventive measures to avoid future problems.


While salt may seem like a natural and straightforward solution for bed bug control, it is not an effective method for eradicating these pests. Scientific evidence does not support the theory that salt can dehydrate and kill bed bugs. Instead, seeking professional assistance for effective and thorough bed bug elimination is advisable. Professional pest control experts have the knowledge, experience, and access to proven methods to address bed bug infestations and provide long-lasting solutions efficiently.

7. Bed Bug FAQs

Can salt kill bed bug eggs?

No, salt is not effective in killing bed bug eggs. Bed bug eggs are protected by a hard shell that shields them from dehydration. Salt cannot penetrate this protective layer, rendering it ineffective in killing the eggs.

Does salt repel bed bugs?

While bed bugs may try to avoid areas with salt, it is not a reliable repellent. Bed bugs can detect substances that could be harmful to them, including salt. They may find alternative routes or harborage areas to avoid the salt, making it an unreliable method for repelling them.

What is the best way to get rid of bed bugs?

The best way to get rid of bed bugs is to seek professional assistance. Pest control experts have access to effective treatments, such as heat treatments, insecticides, and steam cleaning, which have been proven to eliminate bed bugs and their eggs.

Can I use salt alongside other bed bug treatments?

While salt is not an effective bed bug killer, it can be used with professional treatments as an additional preventive measure. However, it is essential to follow the advice and guidance of pest control professionals to ensure the proper application and effectiveness of all treatments.
