How to Use Baking Soda to Get Rid of Pests – Cockroaches, Fleas, Ants, Mice, and More

Baking soda isn’t just for cleaning and freshening up your home – it’s also a powerful, natural pest control tool! Safe, inexpensive, and chemical-free, baking soda can help you deal with unwanted pests like cockroaches, ants, fleas, moths, spiders, and even mice or rats.

Here’s how to use it effectively for each one.

🪳 1. Cockroaches

How it works: Baking soda reacts with the acid in a cockroach’s stomach, killing it naturally.

DIY Trap:

Mix equal parts baking soda and sugar (1:1 ratio).
Sprinkle in corners, behind appliances, or under the sink.
Roaches are attracted to the sugar and unknowingly consume the baking soda.

🐜 2. Ants

How to use:

Mix baking soda and powdered sugar (1:1).
Place in small shallow lids near ant trails or entry points.
The sugar attracts them, the baking soda eliminates them.

🐁 3. Mice & Rats

What to do:

Mix baking soda with a little peanut butter or flour to form small balls.
Place near walls, behind appliances, or suspected nesting spots.
When ingested, baking soda creates gas – which rodents can’t release – leading to natural elimination.

⚠️ Keep away from pets.

🐛 4. Fleas

How to use:

Sprinkle baking soda on carpets, rugs, or pet bedding.
Brush it in gently with a broom.
Let sit for 12–24 hours, then vacuum thoroughly.
Repeat every few days during infestation.

🦟 5. Moths

How to use:

Mix baking soda with a few drops of lavender or eucalyptus essential oil.
Place in small cloth sachets in drawers or closets to repel moths naturally.
