A fly over the fruit bowl, a cockroach in the kitchen, or a mosquito buzzing at night can make home feel like a battlefield. While chemical sprays are common, you can make an effective, natural repellent with simple household items — safe for kids, pets, and chemical-free living.

This method combines strong scents and natural reactions to drive pests away. Peppermint and toothpaste release an aroma insects dislike, while baking soda and vinegar create a fizz that disrupts their environment. Flies avoid the scent, mosquitoes steer clear, and cockroaches lose their trails.

Mix 1 tablespoon mint toothpaste, 1 tablespoon baking soda, 1 tablespoon white vinegar, 120 ml warm water, and 5–10 drops peppermint oil (optional). Let the mixture foam, then place in shallow containers near trash bins, sinks, appliances, or windows. Refresh every 2–3 days for best results.

Within an hour, the minty barrier takes effect, sending pests packing without toxic fumes or costly sprays. It’s an easy, affordable way to keep your home smelling fresh and pest-free.
