While gnats aren’t necessarily harmful, they sure are annoying! Luckily, there are lots of ways to trap and exterminate these pests without having to resort to using expensive commercial products. Best of all, most of the supplies you need, you probably already have! Whether you've got an infestation on your hands, you're looking to prevent one from occurring, or you just want simple tips for keeping gnats away from you, keep reading: we've got everything you need to know!
Things You Should Know
- Trap the gnats in a bowl of vinegar, sugar, water, and dish soap, or put a vinegar-soap-water mixture in a spray bottle and spray the gnats when you see them.
- Deter gnats from gathering in your house by maintaining a clean environment, free of dirty dishes or rotting food.
- Keep gnats away from you by wearing scents gnats hate, like peppermint, vanilla, or lavender.
Steps
Dealing with Gnat Infestations
-
1Mix apple cider vinegar, water, sugar, and dish soap to trap gnats. Use 2 tablespoons (30 mL) of apple cider vinegar, 1 tablespoon (12 grams) of sugar, 1⁄2 teaspoon (2.5 mL) of dish soap, and 1⁄2 cup (120 mL) of warm water. Combine everything in a small bowl and place it in the infected room. Leave it overnight and clean it out in the morning. Repeat this process as many times as you need.[1]
- The scent of the sugar and apple cider vinegar will attract the gnats to the bowl. When they get close to the bowl, the soap suds will trap them and pull them down into the water.
Tip: You can also use red wine and dish soap to the same effect. Gnats will be attracted to the scent of the wine and will get sucked down into the glass or bowl by the soap.
-
2Cover a bowl of mashed banana with plastic wrap to attract gnats. Gnats love rotten fruit, so you can use this to your advantage to trap them. Simply mash up a banana, place it in a bowl, cover the bowl with plastic wrap, and poke little holes in the plastic with the tines of a fork. The gnats will enter through the holes to get to the banana but won’t be able to get back out again.
- Because this method doesn’t necessarily kill the gnats, make sure to dispose of the banana and the plastic wrap in the outdoor trash. You may even want to use a disposable bowl so you can just throw the entire trap away.

3Dilute bleach and pour it down the drains if gnats congregate near them. Use 1⁄2 cup (120 mL) of bleach to 1 gallon (3.8 L) of water and slowly pour it down the drain. The diluted bleach should kill any gnats that are living in the drain. Repeat this process daily until you no longer notice any gnats.[2]
Warning: Wear a mask and protective gloves when you work with bleach. It also isn’t a bad idea to wear old clothes, just in case you accidentally splash some on yourself.
-
4Spray gnats with a mixture of water, isopropryl alcohol, and dish soap. Mix 1⁄5 cup (47 mL) of water, 1⁄5 cup (47 mL) of isopropryl alcohol, and 1 teaspoon (4.9 mL) of dish soap in a clean spray bottle. Whenever you see gnats flying around, spray them with the mixture: they'll drop to the floor and die.[3]
- This is a great non-toxic way to deal with gnats. It’s unlikely to harm any of your belongings, and it won’t hurt your plants, pets, or kids.
-
5Exterminate pests with a candle and a bowl of water. Place a candle in a bowl or on a tray that is partially filled with water. Light the candle, close the curtains, and turn off all the lights. The gnats will be attracted to either the candle or the candle’s reflection in the water. The candle itself will burn their wings, while the water will trap them.[4]
Warning: Always practice fire safety. Never leave a burning candle unattended, and don’t place this trap near any loose fabric or somewhere it could easily get knocked over.
Removing Things That Attract Gnats
-
1Throw out fruit that has started to rot or keep fresh produce in the fridge. Gnats love fruits that have started to get a little ripe—the sweet smell attracts them by the dozens. When you can, store fruits in the fridge. If you notice that fruit on the counter is starting to rot or attract bugs, throw it out or compost it.[5]
- Similarly, if you collect food scraps for composting, don’t leave the bucket or bowl exposed in the kitchen. Use a covered container, or take scraps directly outside to the compost heap.
-
2Keep your sink clean and clear of dirty dishes. Gnats love moist areas, especially if any food bits are laying around. Make it a goal to wash your dishes or load them into the dishwasher right after you eat. At the least, make sure to clean the dishes and your sink at the end of each day to prevent dirty dishes from attracting gnats.[6]
- Don’t leave prepared food sitting out on the counter for longer than 30 minutes. Store food in reusable containers and put them into the fridge as soon as possible.
- If you have a garbage disposal, make sure to run it after rinsing off your dishes so that food scraps don’t accumulate in there.
-
3Empty the trash bins in your home daily if there are food scraps in them. The longer old food sits in the trash, the more likely it is to attract gnats. You may not need to do this in rooms where food isn’t getting thrown away, but in your kitchen, it can definitely help keep away gnats to take the trash out at the end of each day.[7]
- Similarly, if you have open trash cans outside, make sure they aren’t located next to any windows. The gnats could be attracted to the trash and then find their way indoors through the window.
Tip: Invest in a trash can with a lid that seals. An open trash can is an open invitation to gnats. But a trash can with a lid that firmly closes can keep gnats away from the food and waste inside.
-
4Move potted plants with damp soil outdoors if they’re attracting gnats. If you notice gnats congregating around your favorite houseplant, that might mean its soil is too damp and needs to dry out a little bit. Set it outside or in a garage or shed for a few days until the soil starts to dry out. If this doesn’t work, you may want to repot your plants in fresh soil.[8]
- On the flip side, there are a few plants that repel gnats. These can be potted and kept indoors, or you can plant them outside if you struggle with gnat infestations outdoors. Try growing geraniums, lemon thyme, lavender, and marigolds; these are the best natural repellants.[9]
Keeping Gnats Away from Your Body
-
1Keep a scented dryer sheet in your pocket to repel gnats while you’re outdoors. Dryer sheets are often scented to smell like lemon balm, geranium, lavender, and other fragrances that repel gnats. Simply put a scented dryer sheet in your pocket or wrap it around a belt loop to naturally keep gnats away.[10]
- In addition to keeping away gnats, the dryer sheet may also help repel mosquitos.
- If your outfit doesn’t have a pocket or belt loops, you could pin it to your clothes. It might look a little silly, but it should help!
-
2Dab on a few drops of vanilla extract before you head outside. It turns out that gnats hate the smell of vanilla! Mix together 1⁄2 teaspoon (2.5 mL) of vanilla extract and 1⁄2 teaspoon (2.5 mL) of water. Put the mixture onto a cotton ball and rub it on your neck, wrists, collarbone, and ankles.[11]
- If you’re going to be outdoors for a long time, bring a small container filled with extra extract to reapply throughout the day.
- If you have vanilla absolutes or fragrance oils, these may also work—just make sure they contain real vanilla!
-
3Apply peppermint cream for a minty, natural gnat repellent. Peppermint is another one of those scents gnats just don’t like, and you can make your own cream using essential oils and shea butter. In a small, clean container, mix together 1⁄2 cup (120 mL) of shea butter and 4-6 drops of peppermint essential oil. Rub the cream onto your hands, neck, legs, arms, and any other areas of exposed skin.[12]
- If you don’t have shea butter, use another moisturizer that doesn’t have added scents.
Tip: Rosemary, cedarwood, and geranium oil have similar effects to peppermint oil.
-
4Wear sunglasses and a bandana when walking through infested areas. Sometimes, no matter how hard you try to avoid it, you might end up walking through a heavily infested gnat area. To keep them away from your eyes, mouth, and nose, wear a pair of sunglasses and wrap a bandana around your face. Once you’re away from the area, you can remove these items.
- Gnats won’t harm you—they don’t bite or transmit diseases—but they are annoying and can ruin a nice day. Do your best to be prepared when you go outdoors, especially if you’ll be near still water sources.

So long as you keep your home relatively dry and you don't leave rotting fruit out, you shouldn't run into a big problem with gnats.

About This Article
To get rid of gnats using home remedies, start by filling a jar halfway with apple cider vinegar. Then, cover the top of the jar with plastic wrap and secure it with a rubber band so there are no gaps between the plastic and glass. Next, use a toothpick or fork to poke a few small holes into the plastic wrap so the gnats can smell the vinegar and fly into the jar. Finally, place the jar where there are a lot of gnats, then empty and refill the jar every couple days until they’re gone. For tips on how to make a soap spray that will keep gnats away from your houseplants, read on!
