Does Baking Soda Kill Fleas at Home?


Baking soda is an inexpensive pest remedy used by many homeowners to control flea infestations in the house. Here are some ways you can use baking soda to get rid of fleas.

Baking Soda and Flea Infestations

Baking soda on its own may not be super effective at controlling flea infestations. For best results, mix the baking soda with fine table salt before applying it on flea-infested areas.

Treat Carpets with Baking Soda
Spread a generous amount of baking soda and salt on flea-infested carpets. Scrub the carpet with a push brush to ensure the baking soda reaches the base of the carpet.

Let the baking soda + salt mixture sit in the carpet for about two days before clearing it away with a vacuum cleaner. Throw away the vacuum cleaner bag immediately after you are done cleaning as it may still contain some live fleas.

Treat Flea-Infested Furniture
The salt + baking soda mixture can also be used on upholstered furniture like sofas and chairs. Sprinkle an ample amount of powder on every reachable surface of the furniture. Wait at least a day or two before you clear the powder away with a vacuum.

Unlike pesticide, natural pest solutions like baking soda can take time. Make sure you apply the salt + baking soda mixture multiple times if you are dealing with a big flea infestation.

Treating Flea-Infested Pets
Some flea control guides will suggest using baking soda on flea-infested pets. In this case, you are better off using food-grade diatomaceous earth to kill off any fleas living in your pet’s fur. Diatomaceous earth acts as a desiccant and can puncture the flea’s waxy exoskeleton.
