What is midge fungus?

Fungal rodents include several species of small, short-lived flies. they areoften confused with fruit flies, are similar but have slightly different anatomy, diet, and reproduction. Instead of fruit, fungus gnats are attracted to the warm, moist, and comfortable environment you have created for your potted plants. They may ask for a new roommate you adopt or sneak into your home through doors, windows, or other small openings in your home.

Fungal rodents reproduce by laying eggs in the top few centimeters of moist soil.The eggs hatch into larvae, the larvae feed on organic matter in the soil for 2 weeks, then they pupate. A few days later the adult flies appeared and started buzzing. You will often find fungi eating away at the surface of the soil, the rim of the pot, or possibly around the drainage holes of the pot. Most often they only fly in short bursts and otherwise crawl.

Are fungi harmful to plants or humans?

Parasites do no harm to people, other than being annoying! In small amounts, they won’t harm your houseplants either. However,California Schoolwarning that when unchecked,A large number of rodent fungi can be harmful to plants. Their larvae can start feeding on plant roots, causing stress, yellowing of leaves, wilting and potentially plant death in the most severe cases. Rodents of the fungus can also spread diseases causingShock absorbers- A condition in which young plants or seedlings suddenly wilt and die.


1) Humidity control

As we have already established, rodent fungi love moist soil – and need it to reproduce! As a result, overwatering the plant can easily lead to a mold problem. To prevent and combat fungal gnawing,Avoid overwatering your plantsfrom the beginning. Only provide water when the top few inches of soil have dried out. Remember that the top layer of shallow soil is where the fungus gnaws!

Luckily, most growers don’t mind you reducing their water intake a bit. Truth be told, many plant parents are guilty of watering their plants more than necessary. too much for thatOverwatering is a common cause of death in houseplants!

Another good indicator of humidity control is a drain pan or pan at the bottom of the pot. It will dry out within a day of watering the houseplant, and there is nobackwater. If so, you may be missing out! A full drain pan may also be a sign that your plant’s soil has poor water-holding capacity, is rooted, or that water may flow around the edges of the root ball and soil – rather than infiltrate.

A hand is holding a small amount of soil taken from a potted plant in the background. The soil is light brown and looks fairly dry, there is a decent amount of perlite or pumice mixed in to the soil.Last week I watered the houseplants and the top layer of soil was quite dry.

2) Land Selection

When potting new plants, use reputable plantsquality bagged soil. The pasteurized or pasteurized variety must not contain live eggs, larvae or flies. Avoid using soil from your garden, as it can bring unwanted pests indoors.

After Growing Houseplants, Consider Adding a Garden Layersand(don’t play sand!) to the top of the pitch. You can water the plant through the sand to prevent rodent fungi from laying eggs in the pot. In addition to sand, there island cover products like these(made from crushed recycled glass) specially formulated to get rid of rodent fungi in your potted plants.

3) Prevent the spread

When you bring your new houseplant home, check for the presence of rodent fungi. Unfortunately only the flies are evident as the larvae or eggs are difficult to detect. It’s best to keep new plants away from other houseplants for a few days to monitor them, especially if you suspect they may be infected. Remember that rodents generally cannot fly long distances unless they have to!

Therefore, keep new or infected plants inInsulationcan be very effective in reducing the spread of fungus from rodents to other potted plants. This way you can focus your treatment on just one plant instead of all of them! For severely infected species, some people may choose to completely remove the infected plant from their home.

5 ways to catch mushroom gnats

1) Remove excess moisture

At the first sign of a fungus gnat problem, this should be the first step.Let the top few inches of the plant’s soil dry out. This will make the soil unattractive to adult flies, preventing them from laying more eggs. If you’re lucky, it can also kill a lot of eggs and larvae! Also, eliminate standing water. This includes drain pans in pots, or even other nearby sources – such as leaky pipes, condensate puddles, etc.

2) Sticky trap

Mushroom rodents are attracted to light, in addition to being yellow. Use a yellow sticky trap near, hanging or inside a potted plant to catch adult flies.Sticky traps in depositSpecially designed for potted plants! We also hangthese bigger onesto catch rodents and other flying pestsour greenhouse.

However, keep in mind that fungi eat away most of their life cycle as eggs and larvae, so sticky traps will only solve part of the immediate problem. If the adult flies have laid more eggs, the cycle will continue. However, reducing the adult fly population with sticky traps should help solve the overall problem! Continue to use sticky traps toweeks to completely break the cycleand eliminate fungal gnawing.

3) Use hydrogen peroxide to destroy fungal organisms

If the simple combination of drying out the soil and hanging a few sticky traps isn’t enough, there areNatural and non-toxicproducts used to kill rodent fungi. One option is to use something you probably already have at home: hydrogen peroxide! Good news? It is readily available, easy to use, and does not harm your houseplants. Better news? According to the report, hydrogen peroxide kills fungal eggs, larvae, pupae and adult flies on contact.Sayonara, fool.

To make a hydrogen peroxide solution, first make sure you’re using regular 3% hydrogen peroxide, not industrial products! Dilute a little andmix 1 part 3% hydrogen peroxide with 4 parts water(eg 1 cup of peroxide and 4 cups of water).

Allow floor to dry slightly before applying. Then, spray the surface of the soil thoroughly until it soaks in a few inches. Or, for a deeper and more effective treatment, water the whole plant -soak all the earth. It will fizz and foam, completely normal. It breaks down quickly into water and oxygen molecules, which is clearly not a danger to plants!

4) Biological control of fungal colonies – Bacillus Thuringiensis

Another non-toxic way to treat midge fungus is to use biological controls, such as Bacillus thuringiensis. Specifically, the subspeciesisraelensis, also known asBti.Bti is a type of bacteria that occurs naturally in soil. According to the EPA, Bti contains spores that produce specifically targeted toxins andonly oneaffects the larvae of mosquitoes, black flies and rodent fungi. That is, it does not harm other organisms.

You may have heard us talk about Bt before, but know that there are several types of Bt! Bti is one of the most effective against fungus gnats, whilethis product bt(Bacillus thuringiensis kurstaki) targets caterpillars such as cabbage worms and cabbage silkworms, but is ineffective in killing the fungal rodent.

To apply the Bti, follow the instructions for”Trench of Earth”“On the product you buy. It is generally advisable to water the plants with this solution, as simply spraying the soil surface may not penetrate deeply enough to kill all the midge larvae. Repeat if necessary, as indicated. A popular choice isBrand: Gnatrol. Understood? Natural gnat control…

5) Neem Oil Slice

Similar to hydrogen peroxide or Bti, neem oil can also be applied to infected soil to kill rodent fungus. However, do not use concentrated neem oil! Prepare and apply a diluted neem oil solution following the manufacturer’s instructions on the neem oil product of your choice.Watering with a dilute neem oil solution can help kill rodent fungus and may also repel them in the future.

When buying neem oil, I always recommend choosingHigh quality pure cold pressed neem oilthan premixed products containing many other additives. To thoroughly mix neem oil with water for even and effective application, neem oil will needemulsificationfirst – because oil and water don’t mix easily. Payment termsOur articles explain how to properly mix and use neem oilin the garden, or, for indoor plants!

Fungus Gnats are the bane of many gardeners with indoor plants, especially over the cooler winter months. Jane gives us some tips on how to avoid a gnat attack at your place, and what to do if you already have these unwelcome house guests

As they say in the classics, prevention is always better than a cure, here are some tips to avoid a full-on “Gnat Attack”.

02: 30 | Don’t overwater

Excessive watering can lead to the growth of algae in saucers and on the surface of the soil which fungus gnats will feed on. This is particularly important overwinter, when the irrigation requirement from indoor plants is much lower than other seasons. Overwatering can also lead to weakness or rot in plant roots, making them “soft targets” for fungus gnat larvae.

While a wet soil can be a haven for Fungus Gnats, there are a couple of soil drenches that can be used to eliminate populations that are already in the soil.

03:00 | Soil Drench

Apply a Neem-Oil based soil drench to the affected pots at a rate of 30ml per 10L of water, using about 1L of the mixture per 25cm pot. Repeat weekly for three weeks.

Gnat-loving Nematodes– Just as we dislike the fungus gnats, there is a particular strain of entomopathogenic (insect killing) nematode that just adore them and will make short work of an infestation at your place. Available at some nurseries commercially, these nematodes are applied as a soil drench, and a standard sachet will treat 24 x 25cm pots. Two treatments, a week apart, is all that is generally required to nip your gnat problem in the bud, and these nematodes won’t harm pets, plants, people or beneficial bugs and bacteria.

Remember, you can only use one of these methods, as the Neem-Oil drench may kill the beneficial nematodes also.

03: 42 | Sticky Traps

While store bought yellow sticky traps will work to attract and trap the adult gnats, why not fight gnats with nature, and pop a couple of carnivorous Butterworts (Pinguicula sp.) or Sundews (Drosera sp.) around the house. These gorgeous plants are the living equivalent of fly paper, and use their sticky leaves to lure, trap and digest insects, including fungus gnats.

Mulch your pots – A layer of inorganic mulch like aquarium stones or small pea gravel across the surface of the pots is an effective way to both discourage infestation and break the lifecycle of existing fungus gnats. This mulch layer prevents the females being able to lay eggs in the soil, and the adults from emerging once mature.

We know they can be a real problem for both plants and people, but with these top tips, you can say farewell to freeloading fungus gnats at your place once and for all!
