Gnats are tiny flying insects that can move into your home if they pick up on their favorite characteristics: moisture and sweet smells. Once you have gnats, the infestation tends to only grow since the bugs reproduce so quickly.

There are many methods to control the gnat population in your home quickly and efficiently. Luckily, you can also adopt some simple habits to help avoid future infestations.

01

Types of gnats

Three types of gnats can make themselves at home in your house. All of them are around 1/8th of an in inch long, but they have some distinguishing features.

Fruit flies have red eyes and a striped abdomen, kind of like tiny houseflies (see the photo!). Drain flies have fuzzy antennae, dark-bordered wings, and a dark grey or tan body. Fungus gnats look like minuscule mosquitos, with brown or black bodies and pale legs.

Why gnats turn up

Fruit flies, drain flies, and fungus gnats invade your home from different places. Fruit flies come from overripe or rotting fruit, as their name implies. Drain flies dwell in grime and standing water from drain pipes. Fungus gnats are most commonly found in the moist soil of houseplants.

Now that you know how to identify these gross pests and where they're reproducing, use the following easy methods to get rid of them (hopefully) for good.

All gnats: vinegar traps

Place a jar or bowl of apple cider vinegar, sugar, dish soap and water in an area where you've had a lot of gnat activity. Since gnats are attracted to sweet smells, they'll seek out the apple cider vinegar and sugar in the mixture. They'll die as soon as they touch the mixture since the soap is poisonous to them.

Dish soap is poisonous to gnats and will kill them on contact. Take a bowl or jar and fill it with a mixture of dish soap and water. Place the bowl where you have problems with gnats. As mentioned, the gnats will die as soon as they touch the dish soap mixture in the container.

Drain flies: pour bleach down the drain

If you're experiencing a drain fly infestation, the best tactic is to get them right at the source. Pour some bleach down the drain and let it sit for a few hours to kill the drain flies and their eggs. Before pouring any bleach, open windows and doors in the room to ventilate it and make sure children and pets aren't present.

All gnats: store-bought trap

Gnat traps (like fly traps) are a sticky paper you place in your home to attract and capture gnats. The sticky strip used in the trap smells sweet and therefore entices the gnats to come in contact with it. Since it's also sticky, once they touch the trap, they're stuck and can't fly away.

Fungus gnats: spray neem oil

You can control the fungus gnat population by spraying your houseplants with neem oil. This all-natural spray is comprised of vegetable oil pressed from the fruit and seeds of the neem tree, an evergreen common to the Indian subcontinent. The oil from the neem tree has qualities that repel and kill insects, which makes it ideal for fungus gnat problems. Spray neem oil on your houseplants' soil and leaves to eradicate fungus gnat eggs and larvae. Reapply the oil every seven to 14 days as a preventative measure.

Professional measures: fogging

Fogging is the process of spraying a large volume of chemicals potent enough to kill off the population of gnats in your home. These sprays are available at most home improvement stores. If you decide to use the fogging method, you and your family (including any pets) must leave the house until the directions on the spray bottle say it's safe to return (typically within a few hours). Once it's okay to reenter your house, open all windows to ventilate the remaining chemical fumes.

Keep gnats gone: throw out rotten fruit

Bad fruit is a prime breeding ground for fruit flies. They love the sweet smell, and since fruit is moist, it's also a great place for them to lay eggs. Luckily, one of the easiest methods for fruit fly population control is to throw out fruit once it starts to decay. You'll have a few adult flies around for a few more days but you'll have eliminated their breeding areas to stop their life cycle.

Keep them gone: don't overwater houseplants

Fungus gnats love moist soil. Their favorite place to breed is in the soil of overwatered houseplants. These gnats aren't just annoying, they're also detrimental to your houseplant's health. When fungus gnat larvae hatch, they eat the roots of houseplants for nutrients. This can ultimately kill the houseplant. The best defense against fungus gnats is to avoid overwatering your houseplants. Water just enough so that it drains through the planter holes and allows the soil to dry completely between watering.
