How to get rid of gnats: 10 Positive Ways to Easily Control Them

Gnats are tiny but very annoying insects. They often gather around fruits, sinks, and plants. Their presence can quickly grow into an infestation. A female gnat lays up to 300 eggs at once. That means they multiply fast indoors. You may spot them near drains or garbage bins. Moisture and food attract them inside homes. They are not dangerous, but they are unhygienic.

Their buzzing and movement can also be irritating. You need to act quickly to stop them. In this guide, you’ll learn how to get rid of gnats. We’ll cover simple and effective methods that work. Each method is safe and easy to apply. Whether you have gnats in your kitchen or plants, we’ll help. Keep reading to find the right solution today.

In this guide, we’ll break down clear, actionable steps to identify, prevent, and eliminate gnats from your home. We’ll keep things simple, useful, and most importantly — effective.

1. Understanding What Type of Gnat You’re Dealing With

Before you can figure out how to get rid of gnats, it’s important to know what kind you’re dealing with. Not all gnats are the same.

The three most common types are:

• Fruit flies: These are attracted to overripe fruit, sugary drinks, and trash bins.

• Fungus gnats: They usually live in moist plant soil and fly around houseplants.

• Drain flies: These come from drains and feed on organic buildup in pipes.

Knowing the type helps you find the source and pick the right treatment. Look at where they hang out the most — near fruit, plants, or the sink — and you’ll get a good idea.

2. Remove Their Food and Breeding Sources

Gnats don’t appear out of nowhere. They thrive in specific conditions: moisture, warmth, and access to organic matter. So if you want to know how to get rid of gnats, this is where to start.

Clean up all the attractants:

• Toss any rotting fruit.

• Take out trash regularly, especially if it contains the food scraps.

• Wash dishes promptly.

• Wipe down counters and sinks.

Also, seal up food in airtight containers and rinse recyclables before placing them in the bin. These small actions cut off gnat access to the things they love most.

3. How to Get Rid of Gnats in House Using DIY Vinegar Traps

This is a simple method that works especially well for fruit flies and fungus gnats.

How to make it:

• Fill a small bowl or cup with apple cider vinegar.

• Add some drops of dish soap (this breaks the surface tension).

• Leave it uncovered or cover it with plastic wrap with tiny holes.

Gnats fly in for the scent and sink. Place several traps near problem areas. It’s one of the easiest and most budget-friendly ways to get results.

4. Treat Drains with Baking Soda and Vinegar

If your gnats are coming from the kitchen or bathroom sink, you likely have drain flies. Here’s how to flush them out.

What to do:

• Pour a half cup of baking soda into the drain.

• Follow with 1 cup of vinegar.

• Let it fizz for 10–15 minutes.

• Rinse with boiling water.

Repeat this daily for a few days. It helps clean out gunk and larvae from inside your drainpipes. You can also use enzyme-based drain cleaners as a maintenance routine.

5. Let Plant Soil Dry Between Waterings

Gnats are most likely fungus gnats if they appear to be coming from your houseplants. Their larvae live in damp soil.

To stop the breeding cycle, allow the top 2 inches of soil to dry out completely between waterings. The larvae can’t survive in dry soil.

Consider bottom-watering your plants, which keeps the surface layer drier. You can also sprinkle diatomaceous earth over the soil, which kills larvae without harming the plant.

6. How to Get Rid of Gnats with Sticky Traps

Sticky traps are great for catching adult gnats, especially near plants. You can find yellow sticky traps at garden centers or online.

Stick them into the soil of infested pots or hang them near fruit bowls and trash cans. Gnats are attracted to the color yellow and get stuck on the surface.

While traps won’t eliminate the root cause, they help reduce the adult population quickly and let you monitor the severity of the problem.

7. Take Out the Trash and Clean the Bin Regularly

Even if you take out the garbage daily, if the bin itself is dirty, gnats will hang around. Food scraps and liquids can seep into the bottom, creating a breeding ground.

Every few days, rinse your trash can with hot soapy water. You can also spray it with vinegar or bleach solution. Keep the lid shut tight and use liners to contain any mess.

Also, avoid keeping your bin under the sink if it’s humid or damp. Ventilation matters when you’re figuring out how to get rid of gnats for good.

8. Keep Your Sink Area Dry and Clear

Moisture equals gnats — especially near your kitchen sink.

Don’t leave wet sponges, dishcloths, or food scraps lying around. Dry your sink after use, and clean the disposal or drain guard if you have one. Sponge should be rinsed, wrung out, and stored in a location that allows for appropriate drying.

It’s an easy step to forget, but it makes a real difference when you’re trying to control gnats.

9. How to Get Rid of Gnats in Houseplants: Soil and Drainage Tips

Houseplants are a common gnat magnet, especially if you overwater.

Choose well-draining soil and avoid peat-heavy mixes that retain moisture. If gnats keep returning, consider repotting your plants with fresh soil and a clean container. Always check that the pot has drainage holes.

You can also water with a diluted hydrogen peroxide mix (1 part peroxide to 4 parts water) to kill larvae in the soil — just don’t use it too often.

10. Store Fruit in the Fridge or Use Covers

Leaving ripe fruit on the counter is a surefire way to attract gnats.

Keep fruit like apples, pears, and berries in the fridge once they ripen. For bananas and produce that stay outside, use mesh covers to keep gnats away.

Check your fruit daily and throw away anything that’s starting to rot. It takes just one bad orange to create a gnat problem overnight.

11. Rinse Recyclables Before Throwing Them Away

Soda cans, juice boxes, and wine bottles can still contain sugary residues that attract gnats.

Make a habit of rinsing out all recyclables before tossing them into your bin. It only takes a few seconds and makes your kitchen far less appealing to pests.

Also, keep your recycling bin clean. Give it a rinse with soapy water once a week and make sure the lid seals tight.

12. Repel Gnats with Essential Oils

Some scents naturally repel gnats. Try peppermint, lemongrass, or lavender oil to create a homemade repellent.

Mix 10–15 drops of oil with a cup of water in a spray bottle. Spray it near doors, windows, plants, or trash cans. You can also soak cotton balls and place them in problem areas.

It’s not a kill method, but it’s a good deterrent — and it smells much better than vinegar!

13. Upgrade Your Drain Covers

Standard drain covers often let gnats escape. If you’ve had trouble with repeated drain fly infestations, switch to fine mesh drain screens.

These covers block gnats from crawling up while still allowing water to drain. Combined with regular cleaning, they can be a game-changer in your kitchen and bathroom.

Conclusion: The Key to Success Is Consistency

Knowing how to get rid of gnats is one thing — doing it consistently is another.

There’s no single magic fix. The best results come from combining prevention, cleaning, traps, and repellent techniques. Identify where the gnats are coming from and deal with the cause — not just the symptom.

Keep food sealed, soil dry, drains clean, and trash managed. Use vinegar traps and sticky pads to control existing populations. And most importantly, stay consistent. With these strategies, your home will be gnat-free before you know it.
