How to Use Baking Soda to Get Rid of Pests — COCKROACHES, FLEAS, ANTS, MOTHS, MICE/RATS, SPIDERS, and More

Ingredients

  • Baking soda (sodium bicarbonate) — 1 cup (adjust as needed)
  • Optional: sugar, flour, or powdered sugar (to attract pests) — ½ cup
  • Optional: boric acid (for stronger effect, use with caution) — 1 tablespoon
  • Optional: essential oils (peppermint, eucalyptus, lavender) — a few drops
  • Water (if making a paste) — as needed

Instructions

  1. Basic Dry Powder Method:
    • Mix 1 cup of baking soda with ½ cup of sugar or flour (to attract pests).
    • Sprinkle this mixture in areas where pests are frequently seen—under sinks, behind appliances, along baseboards, inside cabinets, or near pet bedding.
    • The sugar attracts the pests, and when they consume the baking soda, it disrupts their digestive system, effectively killing them.
  2. Paste Method for Mice/Rats or Spiders:
    • Mix baking soda with a small amount of water to create a thick paste.
    • Add a few drops of peppermint or eucalyptus essential oil to repel rodents and spiders.
    • Apply the paste in cracks, corners, or entry points. The paste will dry and help repel or trap pests.
  3. For Fleas and Moths:
    • Sprinkle baking soda on carpets, pet bedding, or fabrics.
    • Let it sit for 15-30 minutes to absorb moisture and kill pests.
    • Vacuum thoroughly to remove dead pests and baking soda residue.
  4. Optional: Adding Boric Acid for Extra Power
    • Mix a small amount (1 tablespoon) of boric acid with the baking soda and sugar mixture for stronger pest control.
    • Use with care, keeping it away from children and pets, as boric acid can be toxic if ingested.

Tips

  • Repeat application every few days until the pest problem is gone.
  • Keep the treated areas dry to maximize effectiveness.
  • Baking soda is safe and non-toxic for humans and pets when used as directed.
  • Store baking soda mixture in airtight containers if you plan to make batches in advance.
