Despite being so tiny, gnats are certainly a massive nuisance. They’re irritating, unsanitary, and can even lead to health problems if left unchecked. But how do you get rid of the annoying little things?
How to get rid of gnats in house? To get rid of gnats in the house, you can set traps to lure and catch them, then dispose of them. You can also create or buy sprays to eliminate them, try using flypapers, or installing bug zappers. For the best results, however, calling a professional pest control service is recommended especially if you have severe infestations.
For this article, we’ve pulled together all the best ways to help get rid of gnats in your home, using natural and chemical means. First, let’s talk a little about how and why gnats find their way into your home in the first place.
Gnat Infestation in House
Gnats are tiny, and they can get into a house through almost any opening, including the holes in window screens if they’re large enough. Once you get a few gnats inside your home, it doesn’t take long for more to follow. One or two gnats can quickly turn into an infestation, but why do they come inside?
Why Do I Have Gnats in My House?
Gnats find their way inside your home for several reasons. Sometimes, you may bring them in when you bring in a new houseplant. Additionally, some of them come in through cracks in your house because they’re attracted to the light.
Gnats are more of a problem during the day than at night. However, when they do come out at night, your home is like a shining beacon in the dark.
What Attracts Gnats in the House?
Gnats come in because they’re attracted to all the exciting smells from inside your house. They love fruit, even rotting fruit, but they also like garbage, houseplants, and other sweet-smelling things. Likewise, they’re attracted to warm, moist areas like kitchens and bathrooms.
So if you have lots of houseplants or keep plenty of fruit, don’t be surprised if you start seeing gnats swarming around them. Once they get inside, they also like to hang around drains, particularly those in the kitchen sink, though the bathroom sinks aren’t off-limits either.
How Do Gnats Get in Your House?
The term “gnats” is a catch-all word for any number of small flying insects. These can include species such as midges, no-see-ums, sand gnats, fruit flies, and others. Most of these insects are no more than ⅛ to ¼ of an inch (3.175 – 6.35 mm) long. Things that small can get in practically anywhere.
They can fly through open doors, come in along with houseplants, fly through cracks around windows, or come through window screens. If gnats want in, they’ll find a way.
Additionally, you could be bringing home gnats whenever you bring home produce from the supermarket. Sometimes they’ve already laid their eggs in produce, and when you bring it home, the gnats hatch and swarm inside your home.
Where Do Gnats Come From in the House?
Once gnats get into a home, they look for moist, dark places to hang out when they’re not feeding. Some of them like to stay in drains because they’re dark and full of decomposing matter for them to eat. Kitchen drains are especially coveted.
They also make their homes in pantries, fruit bowls, garbage cans, and anywhere else that’s dark, moist, and not too hot or too cold.
Types of Gnats in House
Because “gnats” is such a catch-all term, there’s no single specific type of gnat that comes inside. Instead, the gnats in your house could be any number of tiny, flying bugs. However, a few types of “gnats” are more likely to come inside than others. Those include:
- Fruit flies
- Fungus gnats
- No-see-ums (biting midges)
- Sand gnats (sand flies)
- Houseplant gnats
- Drain flies
- Eye gnats
- Buffalo gnats
- Hessian flies
9 Ways on How To Get Rid of Gnats Inside the House
Now that you’ve learned what types of bugs come inside your house and why they’re attracted to it, let’s talk about what’s really important: Getting rid of them! There are numerous ways to do this. Some are natural, and others involve using chemicals or pesticides. Take your pick:
Lure Gnats Into Rotten Fruit Jars
One way to catch gnats in a trap is to use their love of rotten fruit against them. If you have a rotten banana, apple, or another piece of fruit, don’t trash it! Instead, mash it up and put it in a fruit jar with a lid.
Put the lid on, and stretch a piece of thin plastic, such as the Glad Cling Wrap. Poke holes in the top so the gnats can get to the fruit. The enticing smell will draw them in, and they’ll be able to squeeze through the tiny holes. However, once they’re in, the plastic wrap won’t allow them to get back out again.
Use Diluted Bleach in Your Drains
If you’re having a problem with gnats in your drains, use diluted bleach to eliminate them. Mix a half-cup of bleach with a gallon of warm water, and slowly pour the mixture down the drains where the gnats stay.
This mixture should get rid of them and whatever enticing smells are drawing them there in the first place. You may also want to wash the entire sink with the mixture for good measure.
Place Homemade “Gnat Traps” Near Fruit
If you notice that gnats are swarming around your fruit bowls or a particular area within your pantry, you can set up homemade traps for them. The rotting fruit trap also works, but if you don’t like the smell of rotting fruit in your house, try this instead.
All you need is some apple cider vinegar, a small container, and your favorite dish detergent. We recommend the Sunlight Dish Detergent, which was used in the video below. We’ve also had equally impressive results with Dawn, so use whichever you like best.
This video shows you how to make the trap:
Install Fly Paper
Although it isn’t attractive and no one likes looking at it, flypaper can be effective for gnats. You can hang it in affected areas in your home. If gnats are hanging out around your plants, you can use sticky traps similar to flypaper made for potted plants.

Make Your Own Homemade Zapper Spray
To make this zapper spray, you’ll need the following items and ingredients:
- A plastic spray bottle
- 2tbps apple cider vinegar
- 1L of water
- 1tbsp Sugar
- Dish detergent
Mix water, apple cider vinegar, sugar, and a few drops of dish detergent, and pour it into your spray bottle. Then, you can shoot the offending pests on sight. It’ll get rid of them, but it won’t harm your plants, and it isn’t toxic or dangerous to you, your children, or your pets.
Get Gnats Drunk
Many people wondering how to catch gnats are surprised to learn the answer is as simple as red wine. You can use the same type of plastic-covered container used with the rotten fruit, but instead of fruit, fill it with red wine.
Gnats are attracted to the scent of the wine. They fly in, and the plastic wrap keeps them from flying out. Additionally, you could use dish detergent to hold them in instead.
Hang a Bug Zapper
Hanging a bug zapper is another way to get rid of gnats, although it’s not the most attractive way to do it. The gnats are attracted to the light of the zapper, especially if it’s the only light in a dark room, and will fly into it and fry themselves. Again, not pretty; but nevertheless, it’s simple and effective.
If getting rid of gnats naturally isn’t important to you, there are plenty of chemical sprays you can buy. Just be sure to read the warning labels carefully since some of these products aren’t safe for humans, plants, or animals.
