Does Baking Soda kill Carpet Beetles?

Yes, Baking soda is another common household item that can be used to kill carpet beetles. While it’s not as effective as vinegar, it can be used in conjunction with vinegar or other methods to ensure a more comprehensive solution.

How to Get rid of Carpet Beetles with Baking Soda

Baking soda is toxic to carpet beetle larvae because it is made of sodium that drains their cells. This makes their soft tissues dry and they will die from severe dehydration. Even though it may affect the adult ones, you will have to drown them in a concatenated solution if you want them dead.

When getting rid of an infestation on a carpet, simply spread powdered baking soda on the carpet and let it sit for at least 12 hours. Do this at night when there are fewer movements on it so that the particles are not disturbed.

It is advisable to use it where there are fewer human activities. It has been observed that baking soda can cause skin irritation in sensitive people. Avoid using it on seats or bedding that are actively used. If you have to do so, then keep them covered for some time until the powder is removed.

How long does it take for Baking Soda to kill Carpet Beetles? 

The effectiveness of baking soda on carpet beetles depends on various factors such as the size of infestation, the type of fabric, and the method of application. Generally, it can take anywhere from a few hours to a couple of days for the baking soda to work on the carpet beetles. 

When using baking soda in combination with vinegar or other cleaning agents, the process can be accelerated. In a mixture, baking soda enhances the overall effectiveness, and you might see results in just a few hours. 

If you are dealing with a severe infestation, it’s essential to be patient and persistent with the baking soda treatment. Repeated applications might be necessary to completely eradicate the carpet beetles. 

Remember, while baking soda can be a useful addition to your pest control arsenal, it may not be enough on its own for a large or persistent infestation. Consider combining it with other methods like vinegar or professional pest control services to ensure complete elimination of carpet beetles from your home.

Baking soda for Carpet Beetle Eggs

Baking soda can kill carpet beetle eggs by draining moisture and liquid from their soft layers. This dries them out and they will not be able to hatch as required if they are well dusted in it. Those eggs are soft and are always laid in moist environments that are relatively warm.

The females lay in warm seasons at room temperatures of about 78 F°. When generously spread on an infested area, baking soda absorbs water molecules around the eggs. This makes them exposed to heat and they are easily dried out.

Carpet beetle eggs have an ovate shape with a 0.05-centimeter length and are always laid in clusters. They are always white but they may have an off-white look in some cases. How they look depends on where they are laid because if the place is dusty, those eggs can have a brown look.

Those eggs should be eliminated before they hatch to avoid an infestation. From the day they are laid, they can take about 1-2 weeks before they produce the larvae. This is a very short duration that can easily lead to an infestation.

Baking soda for Adult Carpet Beetles

Using powdered baking soda for adult carpet beetles is tricky because once they are grown, they tend to change their diet from keratin to foodstuff like cereals. They also have a protective shield on them that the powder will not penetrate.

Baking soda is a good way to control an infestation at an early stage because it is toxic to them at the larvae stage. This is a safe non-toxic way that reduces the number of adults since the larvae will not have a chance to develop into adults.

Female hide in fabric materials to lay eggs since it is the only way their young ones will find food after they are hatched. Sprinkling baking soda around the house is always safe for pets as long as they do not leak the powder.

When dealing with an adult infestation, you can mix baking soda with white vinegar and hot water to make a strong solution. Vinegar is harmful to beetles thus adding it to the solution increases the chances of eliminating them. Here is how to make the solution:

  1. Scoop 1/2 cup of baking soda and put it in a bucket
  2. Pour 2 liters of hot water into it
  3. Add 1/4 cup of white vinegar and stir to mix
  4. Pour the solution into a spray bottle and sprinkle it on the infested areas
  5. This will kill carpet beetles, their larvae, and eggs on contact

Important Tips for Using Baking Soda to Kill Carpet Beetles

When utilizing baking soda to eliminate carpet beetles, certain tips and precautions can enhance the process: 

  • Combine with Vinegar: As previously mentioned, baking soda can be used in conjunction with white vinegar to create a more potent solution. The combination creates a reaction that can be more effective in killing both larvae and adult beetles. 
  • Avoid Over-Saturation: While baking soda is generally safe for most fabrics, avoid soaking the material in a baking soda solution, as it might cause discoloration or damage to delicate fabrics. 
  • Test a Small Area First: If you are unsure how your fabric will react to baking soda, test a small hidden area first to ensure there’s no negative impact. 
  • Protect Pets and Children: Ensure that pets and young children are kept away from the treated areas until the baking soda has been thoroughly cleaned up. While generally considered safe, ingestion or skin contact might cause irritation. 
  • Regular Monitoring: Regularly inspect for signs of infestation, and repeat the treatment as necessary. Baking soda treatments might require multiple applications for total control. 
  • Seek Professional Help if Needed: If the infestation persists or if you’re dealing with valuable or delicate items, don’t hesitate to call a professional pest control service. They can provide specialized treatments that are tailored to your specific situation.

Does Baking Soda kill Carpet Beetle larvae? 

Yes, baking soda can kill carpet beetle larvae. The larvae stage of carpet beetles is particularly harmful, as they are responsible for eating and damaging fabrics. Baking soda works against larvae by absorbing the moisture from their bodies, leading to dehydration and eventual death. 

The effectiveness of baking soda on larvae may vary, and it might take a few applications to see significant results. It can be combined with vinegar or used as part of a broader pest control strategy to ensure complete eradication of carpet beetle larvae. 

Do Carpet Beetles eat Baking Soda?

Carpet beetles do not consume baking soda as a food source. Instead, baking soda acts as a desiccant that absorbs moisture from the beetles’ bodies, including both adults and larvae. 

The application of baking soda on the areas infested by carpet beetles will cause them to come into contact with the substance. While they don’t eat it, the contact with baking soda leads to dehydration, which can be lethal to the beetles. 


We hope the information provided in this blog can serve as a starting point and guide to help you maintain a carpet beetle-free home. Remember, dealing with a carpet beetle infestation may require persistence and a combination of methods. Baking soda offers a readily available tool in this fight, but don’t hesitate to seek professional help if the infestation persists.
