How to Use Baking Soda to Get Rid of Pests: Natural, Effective, and Safe

Mix equal parts baking soda and sugar.

Place the mixture in shallow lids or under sinks, behind appliances, and near suspected roach trails.

Sugar attracts roaches; baking soda kills them when ingested.

2. Ants

Sprinkle baking soda directly along ant trails, entry points, and around windowsills.

Mix with sugar if needed to lure ants into ingesting it.

3. Fleas

Sprinkle baking soda on carpets, rugs, and pet bedding.

Let sit 15–20 minutes, then vacuum thoroughly.

Repeat weekly to keep flea populations down.

4. Moths

Place small sachets with baking soda and a few drops of essential oils in closets or drawers.

Baking soda absorbs moisture and odors, while oils repel moths.

5. Mice/Rats

Mix baking soda with flour in small amounts and place near suspected rodent areas.

When ingested, baking soda reacts with stomach acids to produce gas, helping to eliminate them.

Use with caution and avoid areas accessible to pets or children.

6. Spiders

Sprinkle baking soda around baseboards, window sills, and corners.

Optionally, mix with peppermint oil to enhance repellent effects.
