Gnats and fruit flies may be tiny, but they can quickly turn your home into a buzzing nuisance—especially during the warmer months. These pests are drawn to fruits, vegetables, plants, and even trash bins, and once they appear, they seem to multiply overnight. Beyond being annoying, they can also spread bacteria and contaminate food. Thankfully, there’s a simple, non-toxic way to send them packing—straight from my nana’s collection of trusted home remedies.
Nana’s Easy, Eco-Friendly Solution
While most people reach for chemical sprays or insect traps, my nana always preferred natural fixes that work just as well—if not better. Her go-to method for banishing gnats and fruit flies uses just three everyday ingredients. It’s safe, affordable, and surprisingly effective.
What You’ll Need
- ½ cup apple cider vinegar
- A few drops of dish soap
- A small amount of water
That’s it! No harsh chemicals, no expensive gadgets—just simple household staples.
How to Make and Use the Trap
1. Pour about half a cup of apple cider vinegar into a small bowl or shallow dish.
2. Add a few drops of dish soap. The soap breaks the surface tension so the flies can’t escape once they land.
3. Mix in a splash of water to dilute the vinegar slightly—this actually makes the scent more appealing to the insects.
4. Place the dish near areas where you see the most activity (like near fruit bowls, trash cans, or plants).
5. Wait and watch—within hours, you’ll see gnats and fruit flies caught in the mixture.
Refresh the solution every two or three days, or sooner if the bowl fills up.
Why It Works
Apple cider vinegar gives off a fermented aroma that mimics ripening fruit—the very scent that gnats and fruit flies can’t resist. When they land on the surface, the dish soap reduces the liquid’s surface tension, causing them to sink and drown. It’s a simple scientific reaction that makes this method so effective.
Extra Tips to Keep Pests Away
Once you’ve gotten rid of the gnats, a few simple habits can help keep them from returning:
- Store fruits and vegetables in the refrigerator.
- Empty trash bins frequently and keep them covered.
- Avoid leaving dirty dishes in the sink.
- Don’t overwater houseplants—gnats love damp soil.
- Remove decaying leaves or organic debris from around your plants.
Common Questions
Q: How often should I replace the mixture?
A: Every 2–3 days, or as soon as it’s full of insects.
Q: Is this method safe for kids and pets?
A: Yes—since it’s made from vinegar, dish soap, and water, it’s non-toxic. Just keep it out of reach of little hands and paws.
Q: Can I use white vinegar instead?
A: You can, but apple cider vinegar works best because of its fruity, fermented scent.

Gnats and fruit flies don’t have to take over your kitchen. With my nana’s simple 3-ingredient remedy, you can tackle the problem naturally and keep your home fresh and pest-free. Her method is a gentle reminder that sometimes the smartest solutions are the simplest—and already sitting in your pantry. Give it a try and enjoy a gnat-free home the natural way.
