Does Baking Soda Kill Bed Bugs? A Deep Dive

Bed bugs are a prevalent issue that can severely disrupt your daily life and sleep quality. One commonly recommended DIY method for dealing with them is using baking soda.

The question is, does baking soda kill bed bugs? This guide aims to provide an in-depth answer to this question while considering effectiveness, practicality, and safety.

Will Baking Soda Kill Bed Bugs?

Baking soda can have a desiccating effect on bed bugs, potentially leading to their death by dehydration. However, the scientific evidence supporting this claim is limited, making it an uncertain solution for full extermination.

How Does Baking Soda Kill Bed Bugs?

Baking soda works by breaking down the waxy protective layer on a bed bug’s skin, causing them to dehydrate. However, to achieve this effect, the baking soda particles must come into direct contact with the bed bugs.

How Long Does Baking Soda Take to Kill Bed Bugs?

When used correctly, baking soda can start showing results within a week. The timeline can vary depending on the severity of the infestation and the thoroughness of application.

How to Use Baking Soda to Kill Bed Bugs


  1. Identify Infested Areas: Focus on beds, furniture, and corners.
  2. Clean & Vacuum: Before application, vacuum all identified areas thoroughly.
  3. Apply Baking Soda: Sprinkle a fine layer of baking soda over targeted areas.
  4. Vacuum Again: After 7 days, vacuum the baking soda and any dead bugs.
  5. Repeat: Depending on the level of infestation, you may need to repeat the process.

Incorporating a high-quality mattress into your bed bug eradication plan can make a significant difference. Consider a Puffy Lux Mattress for its hypoallergenic and dust-mite resistant features.

Does Baking Soda Kill Bed Bug Eggs?
