We plant lovers don’t want to witness plants being harmed by pests. The problem enters our homes, which is gross, therefore we especially don’t want to see pests in our houseplants! Fungus gnats are pesky, winged insects with little wings that resemble mosquitoes and are about the size of fruit flies. The good news is that compared to many other pests, these plant flies cause significantly less harm, and even better, they’re rather simple to get rid of.
Long legs, transparent wings, and a preference for nutrient-rich, damp soils are characteristics of fungus gnats. These little flies may be seen flying around plant containers, but unlike some more dangerous pests, you won’t observe them actually chewing on the plant’s foliage. However, you will see them in the soil, feeding on the organic matter and hairs from plant roots. Do not underestimate the damage that these bugs can still do if not addressed.
Even though adult fungus gnats only live for about a week, they can have a big impact in that short time by producing up to 300 eggs under the correct circumstances. With such a quick turnaround and a brief life cycle of about 3–4 weeks, populations can grow incredibly quickly.
It’s rather simple to tell if your plant has a fungus gnat issue. Since these plant flies can’t fly very well, they usually stay rather near to the plant. They’ll probably be moving in zigzag patterns while you watch them. It’s typical to witness all the different phases of this bug at once because they reproduce so quickly. It’s likely that some bugs still in their larval stage will be visible if you gently agitate the soil. They inhabit the earth where they eat organic debris and have translucent bodies and glossy, black heads.
Our plants are getting ready to settle in for the upcoming cold season as winter approaches here in North Dakota. Unfortunately, that signals that these pesky bug populations are about to reach their peak. During this time, dormant plants use less water, which causes their soil to stay moist for longer. Gnats thrive in moist soils because they promote root rot and fungus. Be cautious when bringing delicate plants inside to overwinter since you run the risk of inviting unwelcome pests into your house.
Your plants will start to exhibit signs of stress if ignored and neglected. Fungus gnats don’t directly harm plant leaves, but they eat the root hairs and deplete the soil of vital minerals. This may result in abrupt plant withering and yellowing of the leaves, sluggish development, and a general decline in vigor.
When tackling any pest, you should always start with natural management approaches. The least hazardous and disruptive to your plant and house are typically natural and organic remedies, while chemicals may occasionally be required as a second line of defense. Fortunately, most fungus gnat populations may be controlled and eliminated naturally provided they are discovered and dealt with in a timely manner. Remember that one plant container can hold three to four generations of bugs, so you’ll probably need to apply your favorite approach more than once. Gnats in your indoor plants can be managed in the following ways:
Do not overwater. Before watering your indoor plants, allow the top couple of inches of soil to dry up. This will not only stop fungus gnats from deciding that your plant would make the best place for them to live, but it will also interfere with their reproductive cycle and assist to reduce populations that have already moved in.
Activate sticky traps. Not just for mice, either! Sticky traps are easy fixes for many pest issues. Gnats that are moving will be caught if you place them immediately on the soil’s surface. To stop them from laying eggs, remove them from the trap, discard them, and replace it frequently (every two to three days). Particularly effective at drawing these insects, yellow traps are.
Create vinegar and cider traps.
Mix equal volumes of cider and vinegar in a shallow dish or can to act as a trap for fruit flies. Lay the trap on the soil surface inside the container or even next to the damaged plant. The concoction will attract the bugs, who will then fall into it and drown.
Bring in useful nematodes. Although it may seem counterproductive to introduce additional bugs into the equation, doing so is a simple way to reduce pest numbers. Nematodes are incredibly minute, worm-like insects that are frequently invisible to the unaided eye. In their larval stage, they attempt to infiltrate fungus gnats and other insects, releasing a bacteria that eventually consumes the pest from the inside out. When you think about it, it’s awful and disgusting, but not as disgusting as allowing gnats to devour your prized houseplants!
If all else fails, there are always insecticidal goods and sprays to keep pest numbers under control. There are many products available that either target the adult stage or the larval stage, but either is OK. You should be able to get rid of these unpleasant plant flies in a few of weeks as long as you successfully target one phase of their life cycle and reapply often.
Larvae are easily eliminated with hydrogen peroxide since it kills them immediately upon contact. Infuse your soil with a solution made of four parts water and one part hydrogen peroxide.
To destroy larvae, neem oil can also be put to the soil after being diluted with water. Neem oil can also be sprayed on surfaces to instantly kill adult flies. Last but not least, pyrethrin sprays contain extracts that are harmful to a variety of pests and can instantly kill flies and fungus gnat larvae.
Fungus gnats can affect the health of your houseplants even though they don’t transmit any diseases that are dangerous to humans. Your plants will thank you by giving off a lush, healthy appearance to enliven your home if you keep pests at away.

What are the tiny flies I’ve noticed in my houseplants?
Have you noticed that whenever you water your houseplants, tiny insects flutter up from the pots? They are small flies, or “fungus gnats,” approximately 1/8 of an inch long, attracted to damp potting soil and decomposing leaves on the soil’s surface around your plants. They resemble little mosquitoes, but they don’t bite, as you’ll see if you see one up close. Additionally, fungus gnats don’t do much damage to plants, but they can be a pain to have around. Fortunately, there are steps you can take to make your indoor plants less inviting to pests in the first place. And there are ways to get rid of fungus gnats if they have already gotten in.
In moist potting soil, fungus gnats love to lay their eggs. The eggs hatch into larvae, which eat soil-based fungus (hence their name). The larvae are about 1/4 inch long, with a shining black head and an extended, translucent body that seems to be white. They enjoy organic stuff in addition to fungus, and they occasionally consume plant roots or seedlings. Another clear symptom of fungus gnats in your houseplants is a slime path over the surface of the soil that resembles the footprints of slugs or snails. Since these insects enjoy light, you might see them on your windows, especially if there are any indoor plants nearby.
As soon as you notice gnats in your houseplants, take action. Although it may be tempting to spray the adult fungus gnats, this is typically only a temporary solution because new adults will eventually emerge from the soil-borne larvae. Targeting the larval stage of their life cycle is a more effective strategy. Reducing excessive moisture is essential for getting rid of gnats since they lay their eggs in the moist soil surrounding houseplants. Make sure your houseplants have sufficient drainage and avoid overwatering them. Between routine waterings, let the soil dry out just enough so that it isn’t constantly moist but not so much that your plant starts to wilt. In dry soil, the eggs and larvae typically perish. Do not forget to empty saucers of any extra water that may have accumulated.
It could be time to try a product like the sticky yellow BioCare Gnat Stix Traps ($10, Amazon) if drying out the soil doesn’t work. To catch the adults and decrease the quantity of eggs the fungus gnats lay, place one sticky paper close to your plants. Avoid touching the plant’s leaves with the trap. When they become covered in gnats, inspect them every few days and replace them with new traps. You’ll eventually get rid of every gnat.
In the fall, fungus gnats are typically easier to see. When you bring indoor plants inside for the winter, some might hitchhike on them. Verify that the plants are bug-free before bringing them indoors. Make sure there are no pest infestations when you are going to purchase new plants. When planting or repotting, always use brand-new potting soil.
How can small flies surrounding plants be eliminated?
It’s crucial to act swiftly to eradicate gnats if you spot any symptoms.
There are three quicker ways to get rid of adult gnats hovering around your indoor plants, while you could play the long game and invest in a few carnivorous house plants.
Create a DIY gnat trap using vinegar
- In a bowl, put one tablespoon of sugar.
- To the same basin, add a cup of white vinegar and a couple of drops of dish soap with a pleasant scent. Wrap cling film securely around the bowl.
- Make a number of tiny holes in the cling film. Place the bowl near the house plant and leave it there overnight to capture flies.
Use sticky fly traps
Another choice is to purchase sticky gnat traps if the smell of vinegar deters you from making your own DIY gnat trap. To catch any unwelcome animals, these traps can either be hung from a plant branch or buried in the ground. You can decrease the number of adults in your area while simultaneously lowering the number of eggs laid in the soil around your plants.
Every few days, check the traps, and when the gnats have covered them, replace them. Avoid using the sticky paper to touch the plant’s leaves.
For the most effectiveness, search for non-toxic, double-sided traps.
Use an indoor fly catcher
You’ve dealt with gnats in your houseplants before, right? Then you might choose to make a purchase of an indoor fly catching apparatus.
These gadgets are typically USB powered and draw flies into the trap using a combination of LED lights and blowers.
Kogan sells a $65.04 USB-chargeable smart LED UV mosquito and insect catcher.
How to prevent gnats in indoor plants
Even though getting rid of adult gnats is a terrific first step, it frequently only provides a temporary solution. More adults will emerge from the soil-dwelling larvae. Targeting the larval stage of their life cycle by letting the soil to dry up is a better strategy. The key to permanently getting rid of these annoyances is to reduce excess moisture because gnats lay their eggs in the moist soil around plants.
- Avoid overwatering. Let the soil dry out between frequent waterings—not so much that your plant starts to wilt, but just enough so that it isn’t constantly wet. In dry soil, the eggs and larvae typically perish.
- Select a pot with good drainage since it will keep gnats from depositing their eggs in the soil and will shield your indoor plant from problems like root rot. Don’t forget to empty any saucers that may have accumulated extra water.
Other ways to prevent fungus gnats
In the fall, fungus gnats are frequently easier to see. When plants are brought indoors at the end of summer, it’s possible that insects hitchhike on them.
Verify that the plants are bug-free before bringing them indoors. Make sure there are no pest infestations before you buy any new plants by inspecting them. When planting or repotting, use a sterile potting mixture.
Why do little flies keep buzzing over my plants?
We plant lovers don’t want to witness plants being harmed by pests. The problem enters our homes, which is gross, therefore we especially don’t want to see pests in our houseplants! The little winged creatures known as fungus gnats are about the size of fruit flies and resemble tiny mosquitoes (don’t worry, they don’t sting!). The good news is that these pests are considerably less dangerous than many others, and even better, they are rather simple to get rid of.
What are Fungus Gnats?
It’s probably a fungus gnat if you encounter a little winged bug that resembles a fruit fly fluttering about the soil of your houseplant. They are attracted to damp, nutrient-rich soils and have long legs for a fly their size. Your plants’ leaves have very little appeal to fungus gnats; instead, they prefer the damp earth beneath the plant canopy. They devour the hair roots of your plants and lay their eggs in the top layer of damp soil. Nothing is more impolite than an unwelcome guest laying eggs in your favorite plant and consuming its roots, even though their damage may be modest. These bugs eventually cause wilting, poor growth, and discolored leaves if left untreated.
Signs of Fungus Gnats
If you have a gnat infestation, you already know how noticeable they are. Due to their poor flight abilities, these flies usually stay rather near to the plant. They’ll be moving in zigzag patterns as you watch. Their tiny, transparent larvae could be visible if the dirt is carefully stirred. Yellow sticky cards are an excellent control method as well as a terrific way to keep track of their activity. See more below on that.
The Number One Way to Get Rid of Gnats
Infestations of fungus gnats typically occur when the soil is very damp. Problems might arise when plant parents provide the same care to their plants throughout the year. Consider this: Compared to the winter, our homes are typically brighter and more humid in the summer. In the winter, most plants become more dormant as a result of the changing seasons. You can keep fungus gnats from setting up camp in your plant pots by reducing the amount of water you use.
Gnats deposit their eggs in the top layer of the soil, and the soil must remain moist for the eggs to survive. It can harm the eggs and disrupt the gnats’ life cycle if you let it dry out. Your indoor plants should be soaked from below if your pot allows it. While the soil near the root ball absorbs water, the soil surface remains dry. Place the pot in a dish of water and let the water to seep up through the drainage holes to do this.
What If That Doesn’t Work?
You can intensify your treatment plan if you’ve modified your watering schedule and the gnats are still present or if you want to get rid of them quickly. Here are a few simple methods for getting rid of gnats in your indoor plants:
Apply sticky cards. In our greenhouse, you may have noticed the yellow cards on sticks and wondered what they were for. The cards are positioned directly above the soil’s surface since gnats prefer the color yellow. Checking what you’ve captured allows you to keep track of what you have while also getting rid of all the gnats that land on your credit card. Replace your sticky card every 4-6 weeks (or sooner if it’s bugged), just to be safe.
Larvae are quickly, inexpensively, and efficiently killed upon contact with hydrogen peroxide solution. Spray your soil with a solution made of four parts water to one part hydrogen peroxide.
Although unpleasant, fungus gnats can’t stand a chance against a plant parent with a game plan. To avoid these disgusting bugs, reduce your watering frequency throughout the winter and develop the habit of bottom-watering. You won’t regret it!
