Gnats In The House – What You Need To Know

While most gnats aren’t harmful, they’re irritating and give the impression of a dirty house even when it’s not.

What are Gnats?

Gnats are tiny flying insects of the class Nematocera, the same one in which crane flies, mosquitoes, and midges belong. Due to the significantly small size, gnats are often informally referred to as ‘no-see-ums.’ The most common gnat species include sand flies, black gnats, and fungus gnats. These tiny bugs are considered true insects due to their body structure that contains an abdomen, head, and thorax.

These creatures have mouthparts that can pierce, lap, and suck. Some gnat species can bite and feed on blood, although most feed on plants and other organic materials. The females of numerous outdoor gnat species can bite and transmit diseases. However, indoor gnats never bite. They are more focused on the food you left unattended.

Species of Gnats

1) Fungus gnats

This insect is a common indoor pest that is typically found in or around over-watered potted plants. Fungus gnats are tiny flies, less than one-half of an inch in length, and are mostly black in color. They have long legs and long, thin wings. These flies thrive in temperatures of 70 to 80 degrees Fahrenheit. They reproduce in decaying organic matter that is moist and shaded.

2) Drain flies

Sometimes known as the moth fly, these insects are small, less than one-fourth of an inch in length, with a hairy body and wings that give them a ‟furry” appearance. The adults have long antennae and broad wings that are shaped like a leaf. They are usually found in bathrooms, kitchens and other damp environments. Appropriately named, these flies lay their eggs inside of sink drains. Once the eggs hatch, the larvae feed on bacteria inside the pipes where organic matter, such as hair, tends to collect.

3) Midges

These flying insects closely resemble mosquitoes. However, they have a much shorter snout and the wings are feathered on the females and bushy on the males. They are soft-bodied and range in length from one-thirty second of an inch to 1 inch. They tend to congregate in large swarms near ponds, lakes or slow-moving streams. Midges are attracted to light and often found around porch lights or streetlights. The swarms can be so large that they can be a traffic hazard.

4) Sandflies

Sandflies are golden, brown or gray, depending on the species. They are very small flying insects – only about one-sixteenth of an inch in length – but don’t let their small size fool you. These flies possess a painful bite that feels more like a sting. Their bite can cause redness and swelling in the affected area.

Sandflies are native to tropical or subtropical regions of the world. Females have piercing mouthparts and feed on the blood of mammals. There are six species found in the United States, none of which are known to carry disease. In other parts of the world, however, they have been known to transmit a virus known as sandfly fever. This virus is similar to dengue but is very rarely fatal.

5) Black gnats

Although there is not an insect that is actually classified as a black gnat, many people may use this term to describe a variety of flying insects. Phorid flies, black flies, and fungus gnats are just a few of either black or dark-colored flies that could be misidentified in this way.

Why Are Gnats in My Bedroom?

Like most household insects, gnats often get into houses searching for food and conducive environments to procreate. Let us take a look at the factors that can make these bugs thrive.


Besides food, moisture is probably the biggest gnat-attracting element. Moist conditions in your bedroom can result from the presence of overwatered plants, damp clothes, garbage cans, condensation around windows, and leaky plumbing. If you have any of these, the resulting moisture could be what is attracting the tiny critters into your bedroom.

Vegetables and Fruits

Most insects get into houses in search of food, and gnats are no exception. If you leave fruits and vegetables in the open, their scents are bound to attract these insects. This gets worse if some of the fruits or vegetables are rotten. Remember that half-eaten apple you left on your dressing mirror? Well, it is the source of your bedroom gnat problem.
If you have any ripe fruits in the bedroom, it is good to keep them in airtight containers where the outgoing scent is minimized. Not only will this reduce your gnat problem, but you will also prevent other insects such as ants from getting into your bedroom.

Human Odors

Tears, mucus, body heat, sweat, and carbon dioxide exhaled by a human being can all attract gnats. Additionally, these insects also love the sweet-smelling detergents, hairsprays, lotions, and perfumes we use regularly. In particular, avoid fragrances with fruity nuances if you have a gnat problem.

Well-lit Environments

This does not mean that you should keep your bedroom dark since it will only result in additional problems. However, make sure to switch off lights that are not being used since gnats like flying in well-lit environments. They are not very fond of the dark.

How to Get Rid of Gnats

Before looking at the particular solutions to eradicating gnats from your bedroom, here are some general tips to observe for a gnat-free room.

  • Ensure there are no gaping cracks in your dry boards, windows, or windows
  • Switch off outdoor lights when they are not in use
  • Do not allow the accumulation of puddles around the areas near your house
  • Keep your lawn well-mowed and free of dead plants
  • Keep a potted aloe plant in the house to deter gnats

Deal with the Gnats’ Breeding Ground

For gnats to be swarming your bedroom, they would have to be coming from somewhere. More often than not, this is usually the gnats’ breeding ground. Figuring out where the insects breed depends on the specific gnat species you are dealing with. Fungus gnats normally breed in moist soil. This is usually found in potted plants.

On the other hand, fruit flies breed in areas with rotten or overripe organic material such as fruits and vegetables. They can also breed inside fruits and vegetables. Lastly, phorid flies breed well in areas made moist by leaky plumbing. You can easily deal with this by keeping your bedroom plumbing intact and the bathroom and other nearby rooms.

Kill the Gnat Larvae to Prevent Multiplication

There are numerous commercial and homemade products you can use to get rid of gnat larvae. For fungus gnats, a combination of coarse steel wool and sticky traps does the trick if you prefer homemade solutions. When the baby gnats emerge, they are shredded by the coarse steel wool as they attempt to move. Fruit fly larvae can be easily controlled by disposing of overripe fruits and rotten vegetables.

Phorid fly larvae are a little tougher to control since they hatch inside drainpipes or in sludges. To eliminate these, wipe the outside areas of your drain with soapy water and then wash down the insides with a diluted solution of white vinegar. You can use any of a wide range of available insect control products.

Add Some Hydrogen Peroxide to Your Potted Plants

To eliminate the fungus gnat larvae that thrive in moist soil, add a 1-part hydrogen peroxide solution and four parts water to the soil. You will instantly notice some bubbling in the soil, don’t worry. It only means that the solution is working. This will work for larvae control as well as the deterrence of fully-grown gnats.

Use a Gnat Trap

If your gnat problem is already beyond the preventative stage, then your best solutions involve eradicating the gnats. You can make effective homemade gnat traps using common household items. Here are some ideas.

Using Plastic Wrap and Apple Cider Vinegar

Pour some apple cider vinegar into a glass and cover the top with plastic wrapping. Fasten the wrapping onto the side of the glass using an elastic band. Poke a few holes onto the top of the plastic wrapping. The gnats will be attracted by the apple cider vinegar, get into the glass, and get trapped.

Using Overripe Fruit, Vinegar, and a Paper Cone

Pour some vinegar into a jar and add a sizable chunk of overripe fruit. Insert the paper cone into the jar with the wide end facing upwards. The scent of the overripe fruit in vinegar will attract the gnats. They will get into the jar using the paper cone and get trapped.

Drown Gnats Using Dish Soap and Vinegar in a Bowl

Pour vinegar into a bowl and add a few drops of dish soap. The latter reduces the surface tension of vinegar, causing any gnats that land on the bowl to sink instantly.

Use an Almost-empty Bottle of Wine

Since gnats love the sugary smell of wine, they will be instantly attracted by the scent and get into the bottle. The narrow neck will keep them trapped. You can also try this method using an almost-empty bottle of beer.

Purchase a Gnat Trap

If the homemade traps mentioned above sound like too much work for you, head over to Amazon and purchase a gnat trap. This guide outlines some stellar options to consider if you choose to go this way.

[FAQ’s] Consumer Questions & Answers

What brings gnats into my bedroom?
Gnats are attracted to moist areas and fruity scents. Items such as unclosed wine bottles, uncovered food, overripe fruits, and overwatered potted plants can all contribute to gnats’ presence in your bedroom.

How Can I Keep Gnats Away?
You can use homemade gnat traps using apple cider vinegar, overripe fruits, and plastic wrapping. Pour some vinegar into a jar, add a piece of fruit, and cover with plastic wrapping. Poke holes into the top of the wrapping where gnats can go through and get trapped.

How come gnats appear out of nowhere?
Well, they do not exactly ‘appear out of nowhere.’ Instead, the eggs that have been laid often hatch, giving rise to more gnats, which can easily seem like they came out of nowhere. It is very easy to miss the gnat eggs and maggots due to their small size.

Do gnats enjoy cold air?
Not really. Gnats thrive under humid and warm conditions where food is readily available. These tiny insects will generally perish in cold conditions. However, keep in mind that they might thrive inside your house even when conditions outside are cold.
