But then, a study from the University of California shows that fungus gnat larvae in large numbers can severely damage the roots of plants and cause such plants to have stunted growth, especially young plants. This is majorly observed in greenhouses and nurseries.
Since indoor plants are mostly moist, tender, and organically-rich, there may be significant damage to such plants as the larvae feed continually on plants roots till they get wilted. The larvae emerge as full-blown adult flies. There are records of severe cases that may result in the death of the plants.

When used to get rid of gnat larvae, they are poured onto the soil in a solution. The roundworms then set to work destroying the fungus gnats in a fairly disturbing way.
The microscopic worms enter the gnats via the mouth, breathing pores and other orifices and release bacteria that actually digest the gnat from the inside out.

Gently spray the potion on the leaves and stems of the plant where the adult gnats are present. Make sure to repeat the process daily until theres no sign of the fungus gnats left.
To avoid spraying your furniture or surrounding with the hydrogen peroxide solution, make sure to place a newspaper or similar item on the opposite side of the plant while spritzing it.

Heres What Works But You Probably Shouldnt Try It
There are some things that will help but that plant experts caution against. One is a diluted hydrogen peroxide soak. You dilute hydrogen peroxide in water at about a 1-3 or 1-4 ratio and thoroughly soak your plants soil until it comes out through the drainage holes. Youre not just giving your plant a regular watering, Savio said. Its a thorough drenching of the whole container, ideally two to three drenches in one go to make sure you reach everywhere. The hydrogen peroxide will kill the larvae.
But there is a small problem and a big problem with this solution.
Small problem: Your soil is very wet. Once the hydrogen peroxide is done fizzing, your plant is now a very fertile target for more gnats.
Big problem: The hydrogen peroxide kills everything in your soil, including the good stuff.
You dont want dead soil, Jones told me. Healthy soil is a vibrant ecosystem with beneficial bacteria and microorganisms that help your plants grow. Murdering them is bad.

If you do this and you go about five weeks without seeing any new gnats, you have to repot your plant or aggressively feed the soil with things like compost tea or worm castings.
That insecticide stuff it does work. But I just dont like to have those chemicals in my life, said Adams, the horticulturist.
Overwatering: A Classic Mistake
Overwatering is the cause number two, after infested soil, for fungus gnats in potted plants .
This is particularly true in autumn/winter. Indeed, what I noticed chatting with gardeners, is that overwatering is caused by lack of any seasonality in the watering pattern. Indeed, in cold and cloudy weather, when not much photosynthesis is going on, not much water is needed. Moreover, the low temperature also reduces the water that naturally evaporates from the growing medium. Hence, during winter, you should water way less your plants.
People forget that, and they end up constantly dumping the plant-soil in the cold season. This is the perfect environment for fungus gnats to lay their eggs.
How to avoid overwatering?
First, to avoid overwatering, it is important to test the soil before applying water. Just stick your finger in the potting mix Is the soil moist? If so, then its enough, no more water is needed. This simple truth is applicable to the vast majority of houseplants and especially herbs. Remember, it is quite often easier to recover a plant from lack of water than too much water.
Second, avoid letting stagnant water sit for too long in trays and saucer beneath pots. Indeed, that water might be closer than you think to the plant roots. Moreover, if dry, the soil will suck water from the bottom, making the situation worse .

The Ultimate Guide To Killing Fungus Gnats
A comprehensive review of the various methods that can be used to combat this common horticultural pest.
They are one of the most common indoor plant pests, affecting thousands of households around the UK each year, and, as anyone who has had a major infestation can attest to, fungus gnats are as hardy and tenacious as they are annoying!
Fungus gnats are drawn to moist conditions and organic matter in plant soil and can be identified in their adult form as they resemble tiny mosquitos, with long legs and a smaller, squat body. In their larval form they are white or translucent with a distinctive black head and can be foundwriggling around just below the surface of the plant soil.
For the most part, fungus gnats are totally harmless as they lack the apparatus to bite humans or animals, but this doesnt stop them from being a major annoyance and fairly unhygienic. However, while adult gnats cant directly damage plants, larval gnats feed on plant roots, over time impeding plant growth and even killing younger plants.
There are no-end of folk remedies floating around online forums, but with so many different purported solutions, it is hard to know which is the best one to use.
Ive decided to put my recent gnat infestation to good use by experimenting with the most common gnat solutions to find out what the most effective gnat-killing remedy is.

Why Do I Have Fungus Gnats In My House
Everyone loves to boast about how clean and well kept their surroundings are, yet the puzzling thoughts of how these nasty gnats get into homes remain unanswered. Its like they travel through space like Antman and appear wherever they feel like!
Well, relax, friend, thats not exactly how they get in. At least one out of the following reasons is why you get fungus gnats in your house.
1. Overwatered houseplants
Having over-watered houseplants is the most common cause of fungus gnats in an indoor setting. Fungus gnats breed in the moist soil region of your plants right from the egg developmental stage.
These eggs develop faster in the warm, moist soil into larvae that then feed hungrily on the fungi and organic waste on the soil it was laid in, after which they grow into full adult fungus gnats.
Similarly, over-watered lawns and their surroundings can be a reason why you have these gnats infesting your privacy.
Monitor how much water goes into your houseplant potting and your lawn, fix all broken faucets, sinks, pipes, and mend the crevices in your water-damaged walls.
2. Unkempt garbage cans
This is, of course, another reason why you have fungus gnats in your home. How well you treat your garbage cans matters a lot if your wish to keep these pests away. Of course, its just a garbage can, but it may also be a breeding ground for these nasty pests and other fly species.
