Put This in Your Home for 1 Hour and You’ll Never See Flies, Mosquitoes, or Cockroaches Again | November 10, 2025

We’ve all experienced that annoying scene: a fly buzzing endlessly around the fruit basket, or worse… a sneaky cockroach darting under the sink. These unwanted guests, as persistent as they are undesirable, can quickly turn your home into a battleground. But what if the solution was already in your bathroom and kitchen cupboard? A simple trick, using everyday ingredients, could make all the difference…

Why do insects flee from this natural mixture?

Imagine a minty breeze tickling your nose… Pleasant for us. But for insects, it’s a red alert! The combination of peppermint and toothpaste creates a powerful scent that mosquitoes, flies, and even cockroaches can’t stand. Add to that the fizzing reaction of baking soda and white vinegar, and you get a chemical and olfactory cocktail these pests will avoid at all costs.

How to make this homemade repellent in 5 minutes flat

No need to be a chemistry expert! Here’s what you’ll need:

  • 1 tablespoon of mint toothpaste

  • 1 tablespoon of baking soda

  • 1 tablespoon of white vinegar

  • 120 ml of warm water

  • 5 to 10 drops of peppermint essential oil (optional but recommended)

  • Small shallow containers (jar lids, saucers, etc.)

In a small bowl, mix the toothpaste and baking soda until you get a smooth paste. Slowly pour in the vinegar — it will fizz, and that’s totally normal! Then, add the warm water while stirring well. For an extra punch, add a few drops of peppermint essential oil.

Pour the mixture into your small containers, then place them in strategic spots: behind trash cans, near sinks, windows, or in dark corners.

And after one hour, what happens?
