What Are Fungus Gnats And Their Life Cycle?

Rid Of Fungus Gnats

Fungus gnats, also known as Mycetophilidae, are small flies attracted to fungi. They often land on the stalks of mushrooms and gnaw at them.

Fungus gnats look like tiny black flies with black hind legs. The size of the adults is similar to a fruit fly or mosquitoes, but they are slightly larger. Their wings are transparent, and their bodies are dark brown.

Fungus gnats have a very short lifespan of about three weeks, which is the perfect environment to multiply.

Fungus gnat eggs are laid in soil with high organic matter or decaying plant matter in very humid areas. They are small and brown. It only takes a few days for the larvae to grow after hatches from the egg. The first two larval stages are the only fungus gnats that have legs. The last larval stage will become a pupa and develop wings, turning into an adult fungus gnat.

How To Identify If You Have Fungus Gnats In Your Garden?

Many people might not notice any signs of fungus gnats in their homes at first. However, if you see tiny black flies flying around your house, then chances are that they might be fungus gnats. Another sign of their presence might be small piles of black dust near corners and baseboards.

Usually, fungus gnats will always be in the same spots, like baseboards or near plants.

Because they love moist organic matter, one of the best places to look for fungus gnats is in plants’ soil, but they can also be found near garbage cans or compost piles.

A great way to check for fungus gnats is to place a few potato pieces near the suspected area. Then, after about three days, if you see tiny black dots, they are probably fungus gnats.

Another way to see if you have fungus gnats is to look for dead areas in your houseplants. Fungus gnats love plants, but they especially like to feed on seedlings and small plants.

The Damage That Fungus Gnats Can Do To Your Health And Plants

Fungus Gnats Can Do To Your Health And Plants

The damage that fungus gnats can do to your health and plants is significant. Fungus gnats can spread diseases such as powdery mildew, harmful to plants and humans. They also release a bad odor that can bother people and other animals.

In addition, these pests damage plants by laying their eggs on plant surfaces and eating the plant’s tissue. This destruction can lead to decreased yields of crops or flowers, so it is important to know how to get rid of fungus gnats.

Destruction Of Young Plants

Fungus gnats are attracted to moist organic matter. They can lay eggs in soil with high organic matter or decaying plant matter. This makes them a nuisance for gardeners, as the larvae can damage young plants. Fungus gnats can also transfer plant diseases from one plant to another, making them a natural hazard for any garden.

Fungus gnats can also cause damage to your houseplants, making them look unattractive. They can brown spots of plants, which are called leaf spots. Fungus gnats are also known for their ‘scavenging’ habits, where they will feed on the roots of plants. This is the leading cause of plant death.

Larvae Can Cause Black Dust To Accumulate.

Larvae Can Cause Black Dust To Accumulate.

The larvae of fungus gnats can cause black dust to accumulate near the baseboards of your house or in any moist environment. This black dust is the feces of the larvae, and it can be a nuisance and health hazard. This black dust is unsightly, but it can also be harmful to your respiratory system.

Adult Fungus Gnats

Fungus gnats are drawn to damp organic materials and can lay eggs in soil with a lot of it or rotting plant waste. As a result, they’re often found near garbage cans or compost piles. Adult gnats may also land on food and drink as they fly around the room looking for an easy meal. They don’t bite people, but other small flies might, so it’s best not to let them get too close.

Fungus Gnats Can Contaminate

Adult fungus gnats can contaminate food with bacteria from their feet. This can be a health hazard, as the bacteria can cause illnesses such as food poisoning. Therefore, it is best to keep them away from your food to prevent contamination.

Adult Gnats Can Carry

Adult fungus gnats are house flies infected with a disease called “fungus gnat midge” or “midge.” This is how they got their name. Adult fungus gnats are not harmful to humans. Still, it is essential to know about the diseases they carry so you can take care of yourself and your family.

  • The most common fungal infection spread by these adult insects is ophthalmic ulcerative stomatitis, which causes painful sores on people’s eyes and mouths.
  • They also transmit gastroenteritis, which causes diarrhea and vomiting in humans.
  • People who have asthma might experience an asthma attack after inhaling the fungus gnat’s body fluids.
  • Fungus gnats can also cause conjunctivitis, sometimes called pinkeye.
  • Adults can also spread disease to pets if they’re allowed to land on them and feed off of their blood.
  • Mites are also known to attach themselves to fungus gnats, which can then be transmitted into your home when flies are around.
  • Adults are also carriers of dysentery, which causes both diarrhea and vomiting in people. Stomach cramps and fever also characterize it.

Adult Gnats Have Been Known To Bite People

Been Known To Bite People

Although fungus gnats don’t bite people often, they have been known to do so occasionally. Adult fungus gnats can contaminate food with bacteria from their feet and spread over 30 diseases affecting humans. They can also carry mites, which can be transmitted into your home when flies are around. So it’s essential to know how to get rid of fungus gnats if they become a nuisance in your home.

How To Get Rid Of Fungus Gnats Naturally

There are a few different ways to get rid of fungus gnats using natural methods. You probably already have some of these methods around your home. In contrast, others may require purchasing items from a store or online. Many natural ways to get rid of fungus gnats are safe for pets and children, so it’s ideal to use these if you have small youngsters running around the house.

Place Yellow Sticky Traps To Catch Adults

Sticky Traps To Catch Adults

Yellow sticky traps can be used to capture adult fungus gnats. These will need to be replaced every couple of days as they become covered in flying insects. This natural way to get rid of fungus gnats doesn’t kill the adults, but it will prevent them from laying eggs and contaminating your house.

Apple Cider Vinegar

Apple Cider Vinegar

Apple cider vinegar kills both fruit fly larvae and adults. Fungus gnats can’t stomach apple cider vinegar as an adult, so it’s safe for them to drink the liquid. However, it’s toxic to them and will kill them if they consume it.

Pouring apple cider vinegar around your plants can also help protect the roots from fungus gnat larvae.

Potato Slices

How To Get Rid Of Fungus Gnats

Fungus gnats are very annoying insects. They can be controlled by simply cutting up a slice of potato and placing it on the ground. This attracts the larvae of the insect. They will crawl under the potato and eat the larvae. Once the larvae are gone, remove the potato and repeat the process until there are no more larvae.

Decaying Fruit and Vinegar Trap

Decaying Fruit and Vinegar Trap

Fungus gnats love rotting things. This makes them easy prey for vinegar traps. Use a plastic cup instead of glass because the gnats will fly out when you shake the bottle. Mix some dish soap and vinegar, then put this mixture inside a plastic cup. Wrap the cup with saran tape and poke a few holes for the gnats to come in. Place the cup near infested plants.

Sprinkling Cinnamon Powder on Soil

Cleaning Up Spilled Liquid Or Food Waste

Cinnamon powder is a great way to prevent fungus gnat larvae from continuing to live in your soil. This works because the smell of cinnamon is toxic to fungus gnats. Sprinkle the cinnamon powder around the ground, and then water your plants. This will work for about a week, but you’ll need to reapply once the smell of cinnamon starts to fade.

An effortless way to get rid of fungus gnats is by cleaning. Don’t leave spilled water, juice, or soda sitting around because the flies will be attracted to it. Instead, clean up any spills as soon as they happen, and ensure all food waste is correctly disposed of.

Keep Soil Dry

The best way to get rid of fungus gnats is by keeping your soil dry. Fungus-growing conditions can lead to an unpleasant odor and result in the spread and development of these pests through pestilence, which may cause plant leaves to curl up or drop off due to their illness-infected roots.

The fungus Gnat is a pesky insect that can cause significant damage to your garden or lawn if not dealt with quickly enough!

Pour a Light Layer of Sand

Pour a light layer of sand to eliminate any fungus that may be lurking in your pool. 

You should do this before closing for the day, so it has time and opportunity, if necessary – which means you won’t have as much work during opening weekend!

Dispose of the Top Layer of Soil Outdoors

To get rid of fungus gnats, dispose of the top layer outdoors. You can do this by removing a small amount of soil from the top of the planter, about an inch deep from the surface. Put them in a burlap bag and dispose of them somewhere outside.

Adding Coffee Ground to Soil

Adding coffee grounds to soil is an age-old method for getting rid of fungus gnats. The astringent properties in the land will kill fungus gnats that love hanging around near your kitchen sink or on outdoor furniture. Since farmers have used it so successfully across generations, you can bet this technique works!

Soapy Water

To get rid of fungus gnats:

  1. Use soapy water.
  2. Fill a spray bottle with soapy water and spray all over the soil. The fungus gnats will be killed instantly.
  3. Be careful not to use too much water as you do not want to drown your plant’s roots. 

If you have a significant infestation, remove any affected plants or planters to prevent further spread of the fungus gnat infestation.

Organic Neem Oil

Neem oil is an organic way to get rid of fungus gnats by being safe to use on indoor plants. It also includes Azadirachtin, a substance that gets rid of insects that have irritated the plant by feeding on it. Unfortunately, it also has a pesticide-like effect on some species of fungus gnats and other types of flying insects. Neem oil can be mixed with water in a spray bottle, or it is available as an organic concentrate that you mix with water. 

When using neem oil, make sure you are not too close to the plants when spraying it on, as this will also kill the plant. Instead, use an eyedropper to get close enough to spray on affected areas of fungus gnats or insects that are feeding on your indoor plants.

Apply Mosquito Dunk to the Soil

Another easy way to get rid of fungus gnats is using mosquito dunks. You can buy these at your local garden center, and they’re very effective when getting rid of fungus gnats.

Mosquito dunks can be found at your local garden center and are great for getting rid of fungus gnats because they do not contain any chemicals that would harm your plants but are very effective in wiping out the insect.

Vacuuming Fungus Gnats

To get rid of fungus gnats, vacuum the soil where you have noticed them. Do not dump the soil outside, though, as this will just carry fungus gnats and cause them to multiply and attack plants in your outdoor garden. Instead, pour the soil into a sealable bag. Seal it, and place it in your freezer to kill off any fungus gnats.

Sprinkle Wood Ashes Over Your Soil Or Use Cedar Mulch

Both wood ashes and cedar mulch will naturally repel fungus gnats by creating an unfavorable environment for them to live in. This method is excellent for those who would like to use a natural remedy instead of chemicals.

Wood ashes and cedar mulch both work well for getting rid of fungus gnats. Along with repelling fungus gnats, they also work well in adding nutrients to your soil. 

Make the Natural Habitat Inhospitable

One of the easiest ways to make your home inhospitable to fungus gnats is by making it difficult for them to reproduce. If fungus gnats cannot reproduce, they will die off, and the problem will be fixed. Covering drainage holes in pots or using a saucer to collect water on top of the soil will stop fungus gnats from laying their eggs in your potting soil.

Use Natural Predators

You can use natural predators to get rid of fungus gnats, such as nematodes. Fungus gnats are vulnerable to these predators, which can be used without nematodes. Fungus gnats are vulnerable to these predators, which can be used without chemical sprays. Spray down your potted plants regularly with water to ensure that nematodes are not washed away, and the fungus gnats should be kept at bay.

Choose Potting Mix Wisely

To get rid of fungus gnats, make sure your potting mix is free from mold or mildew. Fungus gnats love moist potting soil. So dump out the old dirt, mix in some new potting medium to dry it out, and wait a few weeks before re-potting your plants.

Avoid Overwatering Your Plants

Last but not least, another way to get rid of fungus gnats is to avoid overwatering your plants. Instead, keep your plants well-watered but never soggy, and allow the top layer of potting soil to dry between waterings.

Move The Plant To An Area In The Shade

You can also place the plant in an area that gets plenty of sunlight but not direct exposure to the sun. This will keep your plant from getting too moist, and fungus gnats will not feel attracted to it; thus, you will prevent them from breeding.

Replace The Houseplant Soil

To get rid of fungus gnats, simply buy a new bag of houseplant soil. However, if the problem is bad enough to do this, it is best to be safe and use your entire houseplant soil bag in the trash. This will ensure that no fungus gnat eggs are in the soil and stop the infestation from spreading to your indoor plants.

How To Get Rid Of Fungus Gnats Using Chemical Methods?

There are a few different chemical methods that you can use to get rid of fungus gnats. One of the most popular ways to do this is using an insecticide.

Use An Insecticide

You can either buy an insecticide or make your own for killing fungus gnats.

To make an insecticide solution at your home, you will need:

  • One gallon of water
  • One cup of vegetable oil
  • One teaspoon of liquid dish soap

Add the ingredients to a spray bottle and shake well before spraying on affected plants. Be sure to cover the entire plant, including the leaves and the soil.

Using a chemical pesticide to eliminate the fungus gnat is the easiest way. However, using them may harm your plants, and there’s always a chance that it will not eliminate the fungus gnats.

Drench the Diluted Hydrogen Peroxide

To get rid of fungus gnats, fill your garden sprayer with three parts water and 1 part diluted hydrogen peroxide.

Ensure that you wear protective gear when handling this mixture because it’s mighty! Hose off any nearby plants before applying the solution, or they’ll absorb all its goodness too soon into their roots (and die). Amounts of peroxide can be increased or decreased according to your needs.

Note: Always use safety gear when handling this solution because it’s very powerful!

Spray with room temperature water. Use a sprayer to drench the soil around your houseplants with room temperature water until they become completely saturated. The fungus gnats will die from lack of oxygen because the ground will become waterlogged, and they’ll drown in it.

Pre-mix the Sugar with Active Dry Yeast

To make a solution that will kill fungus gnats, mix 1 cup of sugar and two teaspoons of active dry yeast in a small jar with 1 cup of hot tap water. Cover the pot with plastic wrap and wait for it to sit for about an hour.

This will attract the fungus gnats, and they’ll be able to smell it from a distance, so once they’re done feeding, they will have no choice but to lay their eggs in the jar.

After about a week has passed, you can pour the solution into a larger pot filled with the soil you want to get rid of fungus gnats. Be sure to put it away from your other houseplants so that the fungus gnats don’t return.

Faq About How To Get Rid Of Fungus Gnats

Will Fungus Gnats Go Away On Their Own? 

Fungus gnats may go away on their own eventually, but it is unlikely. These pests are attracted to damp and moist conditions, so they are likely to keep coming back unless the conditions that are attracting them are removed.

Where Are The Gnats Coming From? 

The fungus gnats are coming from the outside. They are attracted to the light and heat inside the house. They are looking for a place to lay their eggs. The female gnats lay their eggs in the soil of potted plants. The larvae hatch and feed on the roots of the plants.

What Causes A Fungus Gnat Infestation? 

There are a few reasons you might have fungus gnats in your home. The most common reason is that moisture from the air or water has created an environment for these tiny insects to thrive.

What Are Adult Fungus Gnats?

Adult fungus gnats are tiny, black flies about 1/8″ long. They lay their eggs in moist soil, but they’re not very harmful to humans or other mammals. Fungus gnat adults will either hover around potted houseplants or fly up off the ground and land on surfaces where you walk.

Why Do I Have Adult Fungus Gnats?

Adult fungus gnats can be seen swarming around your houseplants because they are looking for places to lay their eggs. Since females lay their eggs in wet soil, it’s important to control moisture levels inside of your houseplants’ soil to prevent future infestations of fungus gnats.

How Do Fungus Gnats Affect My Houseplants?

Fungus gnats can cause damage to your indoor plants because they prefer wet, nutrient-rich soil like the kind you find in potted plants. They eat away at plant roots which can kill off their leaves and even put them at risk for developing bacterial or fungal infections due to root rot. Fungus gnat larvae also chow down on tiny roots growing into the topsoil, which will stunt your houseplant’s growth.


What can you do to get rid of fungus gnats for good? You have several different options – some natural and some chemical. However, the key to success is correctly identifying the problem and taking action accordingly. All of the methods suggested here require that you remove the conditions which make it easy for fungus gnats to reproduce, so be sure to pay attention to that detail.
