Gnats 101: A Brief Introduction

Before we reveal the magical sprays that gnats can't stand, let's get to know our tiny adversaries a little better.

What Are Gnats, Anyway?

Gnats, also known as tiny flying nuisances, belong to the dipteran family. They're close cousins of mosquitoes, but unlike their blood-sucking relatives, gnats are primarily attracted to overripe fruits, decaying vegetation, and, unfortunately, us! These little buggers are small, measuring only a few millimeters in length, and they're often found swarming around fruits, houseplants, or even your favorite beverage!

The Gnat Lifecycle

To combat these pests effectively, it's crucial to understand their lifecycle. Gnats undergo a four-stage metamorphosis: egg, larva, pupa, and adult. It's the adult gnats that cause the most annoyance, buzzing around and spoiling our peace and quiet.

Now that we've got a basic understanding of our winged foes, let's get to the heart of the matter: What spray do gnats hate?

DIY Gnat-Repellent Sprays

Vinegar Trap – Gnats' Worst Nightmare

Vinegar is like kryptonite for gnats. Here's a simple DIY gnat repellent spray using vinegar:


  • 1/4 cup of apple cider vinegar
  • 1/4 cup of water
  • A few drops of dish soap
  • A small bowl or jar


  1. Pour the apple cider vinegar and water into the bowl or jar.
  2. Add a few drops of dish soap and mix gently.
  3. Place the bowl or jar near the gnat-infested area.

Why it works: Gnats are irresistibly drawn to the sweet scent of vinegar, but when they land in the mixture, the dish soap breaks the surface tension, causing them to sink and drown. Gnats hate this trap!

Essential Oils Spray – A Natural Gnat Repellant

Essential oils are like nature's magic potion when it comes to repelling gnats. They can't stand these delightful scents!


  • 10-15 drops of essential oil (eucalyptus, lavender, or tea tree)
  • 2 cups of water
  • A spray bottle


  1. Mix the essential oil and water in the spray bottle.
  2. Shake well before using.
  3. Spray the solution in gnat-prone areas.

Why it works: Gnats are repelled by the strong scents of these essential oils. They'll steer clear of areas where you've sprayed this mixture.
