🐭 How to Use Toothpaste to Repel Rats and Mice Naturally – A Simple Household Trick That Might Surprise You

By Vitia

Rodents in the home are more than just a nuisance—they can damage property, contaminate food, and spread disease. While many people turn to traps or chemical poisons, there’s growing interest in natural, low-cost alternatives that are safer for families and pets. One such method that’s been circulating in traditional home remedy circles involves a surprising ingredient: toothpaste.

Yes, you read that correctly. Certain types of toothpaste—especially those with strong menthol or peppermint content—can act as a deterrent for rats and mice. These animals have extremely sensitive noses, and the intense smell of mint can overwhelm their senses, making them avoid treated areas.


🧾 What You’ll Need:

  • 2 tablespoons of strong mint or menthol toothpaste
  • 1 tablespoon of baking soda
  • 1 tablespoon of flour or cornmeal
  • A few drops of peppermint essential oil (optional for extra strength)
  • Small disposable containers or bottle caps

🥣 How to Prepare and Use:

  1. Mix the toothpaste, baking soda, and flour into a thick paste.
  2. Add a few drops of peppermint oil if desired.
  3. Place small amounts of the mixture into shallow containers or caps.
  4. Position these in areas where you’ve noticed rodent activity—under sinks, behind appliances, near garbage bins, or in corners of storage rooms.
  5. Replace every few days to maintain potency.

This mixture is not a poison—it works primarily as a repellent. The strong scent discourages rodents from entering or lingering in treated areas. In some cases, if ingested in large quantities, the baking soda may disrupt their digestion, but this method is not intended to kill instantly. It’s a gentle, preventive approach that’s easy to try before resorting to harsher measures.


⚠️ Important Notes:

  • Keep the mixture out of reach of children and pets.
  • This method may not be effective in severe infestations—consult a pest control professional if needed.
  • Always clean affected areas thoroughly before placing the mixture to remove food residues that attract rodents.
  • Results may vary depending on the environment and rodent behavior.

If you’ve been looking for a simple, affordable way to discourage rats and mice from invading your space, this toothpaste trick might be worth a try. It’s easy to prepare, uses ingredients you likely already have at home, and doesn’t rely on toxic chemicals.
