This quick DIY pest repellent uses everyday ingredients to drive away flies, mosquitoes, and cockroaches without harsh chemicals. It’s safe for kids, pets, and anyone wanting a chemical-free option, plus it leaves your home smelling fresh.

The secret lies in strong scents and natural reactions. Peppermint and toothpaste give off an intense aroma that insects dislike. Baking soda and vinegar create a harmless fizz that disrupts pests’ comfort zones. Together, they form a triple-action deterrent: flies avoid the sharp scent, mosquitoes steer clear of the overpowering aroma, and cockroaches lose their scent trails.

You’ll need: 1 tablespoon mint toothpaste, 1 tablespoon baking soda, 1 tablespoon white vinegar, 120 ml warm water, and 5–10 drops peppermint essential oil (optional). Have small shallow containers ready, like jar lids or saucers.

In a bowl, mix toothpaste and baking soda into a smooth paste. Slowly add vinegar — let it foam. Stir
