Baking soda is a household essential known for its versatility in cooking, cleaning, and personal care. However, one of its lesser-known yet highly effective uses is pest control. This simple, affordable powder can help eliminate common household and garden pests without relying on harsh chemicals. Whether you’re dealing with cockroaches, ants, mice, or garden invaders like snails and slugs, baking soda offers a safe and natural solution. Here’s how you can use it to keep pests at bay.
How to Use Baking Soda for Pest Control
1. Cockroaches
Cockroaches are persistent pests, but baking soda can help eliminate them when combined with a sweet lure.
What You Need:
- ½ cup of baking soda
- ½ cup of sugar
Instructions:
- Mix the baking soda and sugar in a bowl.
- Sprinkle the mixture in areas where cockroaches are likely to appear, such as under sinks, behind appliances, and near food sources.
- When cockroaches consume the mixture, the baking soda reacts with moisture in their bodies, creating gas that ultimately kills them.
2. Ants
Baking soda disrupts ants’ digestive systems, making it an effective solution for ant infestations.
What You Need:
- ½ cup of baking soda
- ½ cup of sugar
Instructions:
- Combine equal parts baking soda and sugar.
- Sprinkle the mixture along ant trails and entry points.
- The sugar attracts the ants, while the baking soda eliminates them once ingested.
3. Mice and Rats
Rodents cannot expel gas, making baking soda an effective method for dealing with them.
What You Need:
- ⅔ cup of baking soda
- ⅔ cup of sugar
- ⅔ cup of flour
- Warm water
Instructions:
- Mix the dry ingredients thoroughly.
- Gradually add warm water to form a dough-like consistency.
- Roll the mixture into small balls and place them where rodents are active.
- Once ingested, the buildup of gas in their stomachs proves fatal.
4. Fleas
A combination of baking soda and salt dehydrates fleas, making it an excellent solution for infestations.
What You Need:
- ½ cup of baking soda
- ½ cup of salt
Instructions:
- Mix equal parts baking soda and salt.
- Sprinkle the mixture over carpets, rugs, and furniture where fleas may be hiding.
- Use a brush to work the mixture deep into the fibers.
- Let it sit overnight, then vacuum thoroughly.
- Dispose of vacuum contents outside to prevent reinfestation.
5. Bed Bugs
Baking soda helps dehydrate and eliminate bed bugs naturally.
What You Need:
- ½ cup of baking soda
- Water
Instructions:
- Mix baking soda with just enough water to form a paste.
- Apply the paste to mattress seams, bed frames, and furniture cracks where bed bugs are present.

What You Need:
- 1 cup of baking soda
