Does Baking Soda Kill Fleas?

If you’re dealing with a flea problem in your home, you may have come across suggestions to use baking soda as a DIY flea killer. But does baking soda really kill fleas? While it’s a popular home remedy, the truth is that baking soda alone is not an effective method for flea control.

Here’s what you need to know about using baking soda for fleas and the best ways to keep your home flea-free.

Key Takeaways

• Baking soda is often suggested for killing fleas, but there is no strong evidence that it actually works.
• Some people try mixing baking soda with salt, but this method is not a reliable way to stop fleas.
• Getting rid of fleas works best with vacuuming, washing bedding in hot water, using flea combs, and flea treatments.
• Professional pest control is the best way to fully remove fleas and prevent them from coming back.

Can Baking Soda Kill Fleas?

Baking soda is often recommended as a natural alternative for professional pest control, but there is little scientific evidence to support its effectiveness in killing fleas. The theory is that baking soda dehydrates fleas by absorbing moisture from their exoskeletons.

However, fleas have a protective outer layer that helps them retain moisture, making it unlikely that baking soda alone can kill adult fleas, flea larvae, or flea eggs.

Some pet owners mix baking soda with table salt to create a homemade flea treatment for carpets and pet bedding. The idea is that the mixture dehydrates fleas and flea eggs, preventing them from hatching.

While salt may have some desiccating properties, this method is not a reliable or comprehensive flea treatment.

How to Get Rid of Fleas Without Baking Soda

If you’re a pet parent looking for a truly effective way to get rid of all stages in the flea life cycle, here are some proven methods.

1. Regular Vacuuming

Vacuuming carpets, rugs, pet bedding, and furniture is one of the most effective ways to remove fleas at all life stages. Be sure to empty vacuum bags or canisters immediately after use to prevent fleas from reinfesting your home.

2. Washing Pet Bedding in Hot Water

Fleas and flea eggs can survive on pet bedding, blankets, and soft furnishings, making regular cleaning essential for flea control.

Wash these items in hot water, at least 130°F. Use high heat in the dryer for at least 30 minutes to ensure all eggs and larvae are eliminated. If possible, wash pet bedding weekly to keep fleas at bay.

For severe signs of flea infestations, consider replacing old bedding and vacuuming surrounding areas.

3. Using a Flea Comb

A flea comb is a simple yet effective tool for removing fleas, flea eggs, and flea dirt from your pet’s fur. Comb through your pet’s coat, focusing on areas where fleas hide, such as around the neck, tail, and belly.

After each pass, dip the comb into a bowl of warm water mixed with dish soap to trap and kill the fleas.

4. Diatomaceous Earth

Food-grade diatomaceous earth is a natural alternative that may help dehydrate fleas. Sprinkle it lightly on carpets and pet areas, leave it for 24–48 hours, and then vacuum thoroughly.

5. Flea Treatments for Pets

Flea medications prescribed by veterinarians, flea shampoos, and EPA-approved flea sprays are much more effective than baking soda. Speak to your vet about the best flea prevention for your pet.

Are Other DIY Natural Remedies Any Better?

Just like baking soda, other home remedies get a lot of attention, but they won’t get rid of a flea infestation. Here’s why:

• Apple Cider Vinegar – At best, it might make your pet’s fur less appealing to fleas, but it won’t eliminate an infestation.
• Essential Oils – Oils in spray bottles are sometimes recommended for flea control, but there’s little evidence that they work.
• Dish Soap and Water Traps – It won’t do anything for flea eggs, larvae, or the ones hiding in carpets and furniture.

If the infestation is severe, professional pest control can help eliminate fleas for good.
