How it works: Baking soda reacts with the acids in the roaches’ digestive system and causes internal damage that leads to death.
What to do:
-
Mix equal parts baking soda and sugar (e.g., 2 tbsp each).
-
Place the mixture in shallow dishes or bottle caps and set them near roach-prone areas like under sinks, behind appliances, and along baseboards.
-
Refill every few days for continued effectiveness.
2. Fleas
How it works: Baking soda dehydrates flea eggs and larvae, disrupting their lifecycle.
What to do:
-
Sprinkle baking soda generously onto carpets, pet bedding, and upholstery.
-
Use a stiff brush or broom to work it into the fibers.
-
Let it sit for several hours (or overnight), then vacuum thoroughly.
-
Repeat every few days until the infestation is gone.
Tip: Combine with salt for extra drying power.
3. Ants
How it works: Ants are attracted to sugar but can’t digest baking soda, which disrupts their internal systems.
What to do:
-
Mix 1 part baking soda with 1 part powdered sugar.
-
Place small amounts in cracks, corners, and along ant trails.
-
Replace daily until the colony is gone.
4. Moths (Especially Pantry Moths)
How it works: Baking soda acts as a repellent and keeps areas dry, discouraging moth breeding.
What to do:
-
Clean pantry shelves with a solution of vinegar and baking soda.
-
Place open containers of baking soda in corners of your pantry or closets.
-
Replace every 2–4 weeks.
5. Mice/Rats
How it works: When ingested, baking soda causes gas to build up in rodents’ stomachs, which they cannot release — leading to a lethal outcome.
What to do:
-
Mix 1 part baking soda, 1 part flour, and 1 part cocoa powder (or peanut butter as bait).
-
Place small amounts in shallow containers or near rodent pathways.
-
Keep away from pets and children.
Note: This method works best for small infestations and should be used responsibly.
6. Spiders
How it works: While baking soda won’t kill spiders directly, it’s a natural repellent due to its odor and dryness.
What to do:
-
Sprinkle baking soda along window sills, door frames, under furniture, and in corners.
-
Combine with a few drops of peppermint or tea tree oil for extra repelling power.
Safety Tips
-
Keep away from pets and small children, especially if mixed with sugar or bait.
-
Always vacuum and clean thoroughly after treatment.
-
Repeat regularly for maintenance and long-term prevention.
