Are Fungus Gnats Harmful To Plants Or People
Fungus gnats are not harmful to people, aside from being annoying! In small numbers, they are not harmful to your houseplants either. However, the University of California warns that when left unchecked, large populations of fungus gnats can become damaging to plants. Their larvae may begin to feed on the plantâs roots, which causes stress, yellowing, wilting, and potential death of the plant in the most serious cases. Fungus gnats can also spread disease that leads to damping off a condition when young plants or seedlings suddenly wilt and die.
Do Fungus Gnats Go Away On Their Own
Not likely. Adult fungus gnats lay their eggs and multiply by larvae, leading to possible severe infestations. Some people hope the problem to resolve without intervention, but this is not how things work. However, you should not destroy the plants before you try some of the best methods we describe here to get rid of fungus gnats.

Eliminate Fungus Gnats With Diatomaceous Earth
An effective pest control solution for dealing with fungus gnats is food-grade diatomaceous earth . DE is made from the fossilized skeletons of diatoms.
When the fungus gnat larvae come into contact with the razor-sharp powder, it removes the waxes from the insects body and absorbs the oils located on their outer cuticle. This causes them to become dehydrated and die. To use DE for your fungus gnat problem, sprinkle some of the powder on the soil around your potted plants.
This will help keep the topsoil dry and kill any larvae that are already in the ground. It is essential to continue to add diatomaceous earth after watering the plants to keep the gnats away.
Eggs Were Already Into The Soil
One of the most common indoor gardening mistakes is to use outdoor gardening soil. This is because of the presence of pests, and, among them, fungus gnats are quite common.
However, this is not the only reason. Indeed, also normal potting mix bought from a qualified retailer might still host fungus gnats. Moist organic matter added to the potting mix when produced is very likely to be responsible in this case. Compost and peat moss, for instance, quite often added for the perfect potting mix, are the two main fungus gnats carriers. You might not be the first to receive an infested bag of soil . Indeed, especially their larvae, are hard to spot.

What Can I Do To Prevent Fungus Gnats
There are a few things you can do to help prevent fungus gnats in your houseplants. Some might work better than others depending on the plant, so try them out and see what works best.
1. Let the top few inches of soil dry out
Letting the top few inches of soil dry out helps to keep things healthy and to prevent the moist environment necessary for fungus gnat breeding. Watering in planters without drainage holes can also lead to soil retaining too much moisture, so its best to avoid that too.
2. Aerate the soil
I like to occasionally aerate the soil in my potted plants to help promote air flow. This not only helps with moisture issues in the top few inches of the soilit also helps prevent the soil from caking together too much and shrinking from the sides of the pots.
I like to use a fork or a chopstick for this. Or, if Im being honest, my fingers. You dont have to wait until youve overwatered a plant to do this, either. It can help soil and plant health all the time as long as you dont disturb the roots.
3. Bottom watering your plants
Bottom watering your plants is one way to help prevent fungus gnats. Some plants like to keep their soil moist, so its not a great idea to let them dry out too much between waterings.
Bottom watering is when you set a planter with a drainage hole into water and let the plant soak the water up through the hole. This helps to prevent fungus gnats because the top layer of soil is never really wet.
5. Isolating infested plants
Natural Ways To Get Rid Of Fungus Gnats
An infestation of fungus gnats will cause plants to show signs of wilting, slow growth, and yellowing of the leaves.

Checking The Quality Of A Plant Before Adding It To Your Home
Last but not least, do your homework before you go home with a plant. Home-and-garden centers and specialty retailers work hard to sell a quality product, but they are not perfect.
Its possible the infestation occurs at their store. Before you know it, youve bought a problem plant and brought it into your home or garden.
Do your homework by checking moist areas of the soil before purchasing. If you notice yellowish or white eggs or can visibly see gnats present, leave the problem to the store trying to sell the plant and find another nursery.
Eliminate Their Food Source
Fruit flies won’t stick around if they don’t have anything to feast on. The first course of action is to stick produce in the fridge or inside bins as much as possible. Its best to keep fruit that ripens quickly like apples, grapes, melons, pairs, peaches and plums in the low-humidity crisper drawer produce that is prone to wilting, including leafy greens, carrots and broccoli, belongs in the high-humidity crisper drawer. Bananas are best left on the countertop, ideally in a dedicated banana hanger once ripe, transfer them to the fridge or peel and store them in the freezer in an airtight container.
You should also rinse and dry fruits and veggies as soon as you get home from the store. “There may be some eggs or very, very tiny larvae,” Hartzer says. “By washing them and storing them properly, fruit flies can’t find that food source anymore.”
It’s not so simple for drain flies. Since they prefer bacteria, sewage and gunk in your drain, garbage disposal or seldom-used toilet, it’s important to clear and clean those plumbing lines frequently, especially during hot, humid weather. For drains, pour in a solution of equal parts baking soda and vinegar, wait five minutes, then follow with boiling water. Stubborn clogs might require a harsher treatment Hartzer advises using a drain cleaner like Drano Max Gel Clog Remover to flush out the pipes. If the problem persists, an ongoing infestation may indicate a leak, so call a plumber.

How To Get Rid Of Fungus Gnats In Houseplants
The Spruce / Bailey Mariner
If you’re annoyed by tiny flying insects that seem to appear every time you water your houseplants, you’re probably dealing with gnatsmore specifically, fungus gnats. These pests are attracted to the damp soil of potted houseplants. They need the moist soil as a haven to lay their eggs, and the organic matter in the soil feeds their larvae. Besides being annoying, this feeding behavior can damage your plants.
Although they look a lot like tiny mosquitoes, fungus gnats are small flies of the Orfelia and Bradysia species. They can be identified by their narrow legs, light gray or clear wings, and segmented antennae that are larger than their heads. These are fairly tiny insects. The adults grow to about 1/16 to 1/8 inch long.

- Adult gnats are about 1/8″ long
- Grayish to black in color
- Long legs, antennae, and one pair of wings
- Larvae are each 1/4-inch long with a whitish or transparent body and shiny black head

Fungus Gnat Life Cycle
What’s nice is the adult fungus gnat only lives around one week, but in that time they can lay up to 300 eggs each. In about 4-6 days these eggs hatch into larvae and begin snacking on the roots of your plants in the moisture rich soil.
The pupal larvae grow into adults within 3-4 days and repeat the cycle. As you can imagine, the population can explode exponentially pretty fast.
The whole life cycle from laying of the eggs to adults dying off of old age takes place in 3-4 weeks total, with the range changing depending on the local temperature. This entire life cycle can occur in a single potted plant, hosting several generations at once!
How To Get Rid Of Gnats Outdoors
Instead of saturating outdoor plants with a Bti drench, drop a mosquito dunk labeled as safe for use around pets and wildlife in a watering can or bucket. Let it sit long enough for the dunk to release its insect-killing bacteria into the water. Pour the water over the soil of your outdoor plants. Do this for several weeks to be sure any gnat larvae in the soil are killed.
Don’t use electric pest traps for gnats because they often kill beneficial insects, too. Traps that attract gnats with ultraviolet lights may work, but they only trap the adults, so larvae are left to mature and reproduce.
Some gnats swarm around outdoor lights. To discourage them, switch to yellow “bug lights” or low voltage bulbs, or keep lights near doors and windows turned off.
If you get bitten but can’t see what’s biting you, the pests may be tiny, biting midges, also called sand gnats and no-see-ums. Avoid them by staying indoors on damp, overcast days when the air is still, or cover up when you’re outside. Insect repellants and insect repellant clothing may also help.

Why Are Fungus Gnats Bad
While these pests are a nuisance in noticeable numbers, it might be comforting to know that the adults are harmless insects that do not bite.
Also, they dont do much damage to strong, healthy plants, but they can cause wilting yellowing leaves, stunted growth, and even death in seedlings and more fragile plants.
But honestly, nobody wants a swarm of gnats flying in your face every time you water your houseplants. Yuck.
Food Grade Diatomaceous Earth Controls Larvae And Adults
Food grade diatomaceous earth is highly effective treatment to get rid of fungus gnats. Diatomaceous earth is mineralized fossil dust that is both natural and non-toxic to the environment. Make sure you get food grade diatomaceous earthnot pool grade, which is not pure enough for use around food gardens and pets.
Always wear a simple dust mask when working with DE: Inhaling any kind of dust is never a good idea.
DE contains microscopic shards of silica that physically shred any insect that walks through them, therefore it will not work in hydroponic gardens. But if you mix some into the top layer of infested soilor better yet, into your potting mix before plantingit will kill any gnat larvae that come in contact with it, as if they were crawling through crushed glass.
DE works the same way to kill fleas, bedbugs, slugs and other insects too, so dont use DE to control fungus gnats in your compost bins. Where to find food grade diatomaceous earth online.

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 houseplants growth.
How To Identify Gnats In Indoor Plants
One way to tell if you’re about to run into a gnat problem is to look for eggs. Fungus gnats lay eggs in the soil and these eggs become larvae, which feed on fungi in the soil of plants. The fungus gnat larvae are around 1/4-inch long with a shiny black head and an elongated, whitish to transparent body.
In addition to fungi, they also like organic matter and will sometimes eat plant roots or seedlings, and the plant will appear wilted. Look for a slime trail similar to the kind slugs and snails leave behind. If you can see a trail, it’s likely that there are gnats in your indoor plants.
Gnats also like light, so you may notice them on your windows, particularly if houseplants are nearby.
Gnats are often confused with the common fruit fly but the two insects are completely different. Fruit flies will linger mostly around fruit, and unlike fungus gnats, are tan in colour and look like oval, iniature versions of the house fly.
