How To Stop Fungus Gnats From Damaging Your Weed Plants – RQS Blog
Every marijuana producer strives for the highest possible harvests of enormous buds from their plants. Fungus gnats are a factor that can have a negative impact on the outcome. There are, however, a variety of methods for protecting your plants against this insect. When you put in the time, effort, and money to get a cannabis grow up and running, there is nothing more frustrating than discovering that you have unwelcome guests that are destroying your beloved plants. The fungus gnat is a frequent cannabis pest, which may be seen with mites and other creatures.
What are fungus gnats?
Fungus gnats are small, black, and short-lived gnats that resemble small flies in appearance. They will be seen bouncing about on the earth if you have an infestation on your hands. Fungus gnats, in contrast to some other cannabis pests, have little interest in the leaves or blossoms of your plant since they dwell in the soil where they breed. Instead, the larvae nibble on the roots, causing them to rot. A fungus gnat infestation can be problematic since a strong root system is essential for proper plant development.
Fungus gnats can be an annoyance if you have mature plants with a robust root system, but they can be a tragedy if you don’t take precautions.
They, on the other hand, represent a major threat to young plants and seedlings, which are still developing. It is also possible for larger plants to become afflicted by a major infestation if it is allowed unchecked.
Where do fungus gnats come from?
Fungus gnats are virtually always an indicator of damp conditions in your grow room, and they typically appear when cannabis plants are being overwatered, as described above.
Fungus gnats go through four phases of development: egg, larva, pupa, and adult. Hundreds of eggs are laid in the soil by mature females under favorable conditions of warmth and moisture. During their first two weeks of life, larvae graze on plant material near the soil surface. Adult gnats emerge after 3–7 days in the pupal stage and survive for around eight days after that. Adult gnats require around 3–4 weeks to mature from their egg form. Because fungal spores may be found almost anywhere and are present almost all of the time, all that is required for gnats to arise is moist circumstances and organic debris.
What do fungus gnats do to cannabis plants?
It is not the roots of your cannabis that fungus gnats believe to be a favorite food source. They prefer to eat fungus and rotting materials in the soil rather than plants. However, when the amount of organic matter in the soil is decreased, they constitute a problem. Affected root hairs and the fragile cannabis roots themselves are destroyed by the larvae of fungus gnats in this situation. Symptoms of a fungus gnat infestation include the following:
- When the roots of plants are injured, they can display a variety of disease symptoms, including yellow leaves, withering, spotting, and drooping. Symptoms of nutritional deficits (sickly growth, leaf discoloration, and so on) can develop even when the pH is normal and the nutrients are enough. Seedlings become weak, fall over, and die (a process known as “damping off”). Growth has been slowed, and yields have been poor.
How to spot a fungus gnat infestation
The presence of a fungus gnat infestation is extremely simple to detect. They are little, but you can see them clearly if you approach near to your plants and look closely. Following are some tips on how to identify them:
- The dirt around your plants is being crawled and jumped on by tiny “flies.” In the earth, there are white maggots wriggling about. Because they are so little and may be concealed in the soil, they are difficult to detect. Unusual plant problems, such as pale leaves and blotches, brown margins on leaf edges, and drooping plants that are otherwise unexplained have been reported. Signs and symptoms might vary and may be confused with other plant concerns and illnesses.
How to eliminate fungus gnats from cannabis plants
Insects the size of little “flies” creeping and bouncing on the soil surrounding your plants; In the earth, there are white maggots wriggling about. Given their small size and potential for hiding in the soil, they are difficult to detect. Unusual plant problems, such as pale leaves and patches, brown margins on leaf edges, and drooping plants that are otherwise unexplained are listed below. Other plant troubles and illnesses may manifest themselves as symptoms of this condition.
Water less frequently
The first, and most crucial, thing you should do is reevaluate your watering schedule and habits. Allow the soil to dry completely between waterings; the plants will be OK if you do. The majority of the time, if you follow these instructions, your fungus gnat problem will resolve itself.
Yellow sticky traps
Rethinking your watering regimen is the first and most crucial thing you should do. Between waterings, allow the soil to completely dry out; it will be OK this way. In most cases, if you follow these instructions, your fungus gnat problem will resolve itself.
If you have a pest infestation, you don’t have to go overboard with chemical pesticides to get rid of it. Neem oil might assist you in getting rid of your problem quickly. As a prophylactic step, it’s also effective. It should be applied to the top layer of your soil to eradicate the larvae.
Another natural method for getting rid of pests is to use diatomaceous earth.
Sprinkle the fine powder on the soil surrounding your plants to provide a healthy environment for them. This should be sufficient to eliminate the undesirables in short order.
Blow air over the soil
There are several benefits to using a basic standing fan to gently blow air on your land. One of these methods is to make life difficult for bugs. It will also assist in drying up the soil more quickly, therefore eliminating the gnats for good.
Some gardeners are familiar with the Bacillus thuringiensis bacterium, which is used to get rid of caterpillars. The bacteria Bacillus thuringiensis israelensis is a kind of these bacteria that has been shown to be effective against fungus gnats. All you have to do is add water.
How to prevent fungus gnats
As with everything, prevention is always preferable to cure; here’s what you can do to keep those pesky pests at bay.
Water less frequently!
Above all things, pay close attention to the amount of water you are providing to your plants! In humid, warm environments, fungus gnats nearly beg to be present. Allow the soil to dry up before continuing. Using the “lifting test,” you can determine whether it is appropriate to water. Simply pull your plant from its container and weigh it to see how much heavier it is when completely hydrated vs when it is dry. Only add water if the pot appears to be substantially lighter.
Cover the soil
Given that fungus gnats live and breed in soil, it is possible to cover it with sand, gravel, or perlite to keep them from becoming too comfortable. Please keep in mind, however, that even while covering the soil would prevent the gnats from developing, your plants may still become water-logged.
Sterilise your soil
In other cases, you simply cannot prevent bugs from arriving, such as if they were already present in the soil when you planted the seeds. To be on the safe side, disinfect your soil before you start planting. Fill a flat, oven-safe container such as a baking pan with dirt and cover it with aluminum foil to get this effect. Place a meat thermometer in the center of the pan and “bake” for at least 30 minutes at 82–93 degrees Celsius. While you’re at it, check to see that your pots and growing space are free of debris.
Consider alternative growing media
If you notice that your cannabis plants are regularly “bugged,” you might consider growing them in a different media. It is less probable to have insect infestations when you cultivate cannabis in coco, perlite, or in a hydroponic system.
How to Deter Large Insects
Growing cannabis in a different media may be a good option if you notice your plants are constantly “bugged.” Pest infestations are less likely to occur while growing cannabis in coco, perlite, or hydroponically.
What are Fungus Gnats
Fungus gnats are small black insects that, when viewed via a magnifying glass, have the appearance of mosquitoes due to their size. Depending on how little you want them, they can range from 1/16 of an inch to 1/8 of an inch in height. Where do fungus gnats get their name? When you bring home plants or flowers from the market, gnats are the most prevalent nuisance in the house. They generally arrive within a couple of days of bringing them home. After that, they begin to report to work.
Not only may they infiltrate your houseplants, but they can even find their way inside the grow room. Alternatively, some store-bought soils that are mass-produced will include these concealed invaders that are just waiting to be released on your plants when the soil is turned over.
How to Identify Fungus Gnats on Cannabis
I was first perplexed as to whether they had fungus gnats or apple fruit fly infestations, as I was when I first saw them years ago. But it turns out that they were both. Rather than fruit flies, fungus gnats live in moist soil or coco coir, rock wool, or a combination of these materials.Fungus Gnats vs. Fruit Flies Fungus GnatImage Fruit FlyImage You can see the difference between the two different insects; one is black in color, while the other is more of a yellow, orange color.Not only are they visually different, but they also feed and live differently.The fruit fly lives around rott
Lifespan and Damage Fungus Gnats can do to Marijuana
Unless the fungus gnat’s life cycle is interrupted or they run out of food, it is an ongoing cycle of reproduction. Adult flies, which are around 1/8 inch in size and lay their eggs, constitute the beginning of the process. Which subsequently hatch in 4 to 6 days after being laid. Image The fungus gnat larvae have been hatched, and they will begin feeding on the root hairs on your marijuana plants as soon as they are able. The larvae develop into a form like a maggot and become apparent. Within two weeks, you will be completely developed.
And, as you may have guessed, the cycle continues.
Fungus Gnat Damage
A straightforward question that anyone may ask is if fungus gnats are hazardous to cannabis. The answer is a resounding yes! Fungus gnats infest the soil and decompose organic stuff, causing it to become unhealthy. The larvae feed on this, as well as on the roots and hairs of your fresh marijuana seedlings or the leaves of your developing marijuana plants. Fungus gnat damage can cause growth to be stunted and leaves to begin to turn yellow. The plant progressively dies as a result of root injury, as the roots are unable to absorb the nutrients and water that the plant need.
Causes of Fungus Gnats on Cannabis
Image 1Damp growing media as a result of over irrigation. It’s one of the most important reasons. As a result, it is vital to manage your water and the amount of saturation the plants receive. 2Excess carbon dioxide, generally known as CO2, attracts the attention of fungus gnats.
- You’ve probably been in your house or out in the yard while small flies buzzed about your face. Despite the fact that it is annoying, this is an excellent warning indicator
Alternatively, if you are growing indoors, switch off the CO2 tanks so that you can root out the problem before the problem becomes your roots! 3Confirm that your grow tent or grow chamber has been securely sealed off. They are drawn to soil mixtures that contain compost or peat, whether you believe it or not. 5Soil that has been saturated or coco coir medium 6Houseplants and flowers purchased from retail establishments that were not adequately maintained. 7Open windows that do not have screens.

Growers Guide: How to Prevent and Kill Fungus Gnats
Fungus gnats may not be the most common pest that cannabis growers have to deal with, but if they infest a crop during the early stages of development, these small insects can have catastrophic consequences. A swarm of hungry fungus gnats can have catastrophic consequences for young seedlings and immature plants, especially if they are exposed to high temperatures. Because fungus gnats have a limited lifetime, it is critical to handle them as soon as possible. They are not like other common pests in that they do not gnaw on leaves or suck nutrients from the plant like other common bugs.
Because they are soil-dwelling insects, they are mostly a worry for soil-based producers; nevertheless, a soiled hydroponics operation might cause them to become a problem.
If your cannabis seedlings and young plants become infested with fungus gnats, you’ll need to know how to prevent an infestation from occurring and how to eliminate fungus gnats if they do arise.
As a result, here is your grower’s guide on dealing with a pest that is relatively unknown: the fungus gnat.
What Are Fungus Gnats?
Fungus gnats are so little that you may not even see them in the early stages of an infestation, especially if the infection is widespread. It is estimated that they are around the size of a fruit fly and that they deposit their eggs on the soil’s surface, according to Farmers Almanac. They love settings that are humid and moist, which is characteristic of indoor soil-based cannabis cultivation operations. In addition, farmers using hydroponics who have a buildup of algae or organic debris on their plants may be prone to fungus gnats.
- The eggs hatch into larvae in around three days, after which they begin their search for food.
- The life cycle is complete when adult gnats emerge around 14 days after the beginning of the cycle.
- It is difficult for plants to absorb water and nutrients because fungus gnats eat on their root systems.
- Seedlings, on the other hand, may perish if the infection is severe enough.
Signs of Fungus Gnat Infestation
- The surface of the earth is covered with little black flies that are leaping or swarming
- Yellowing and staining on the leaves
- Potassium, magnesium, and calcium deficiency are three examples of nutritional shortages. Appearance that is stunted or unhealthy The death of seedlings
How to Prevent a Fungus Gnat Infestation in Cannabis
Moisture and cleanliness are the two most important factors in preventing a marijuana fungus gnat infestation from occurring. Fungus gnats are mostly drawn to moist soil, which they feed on. If the soil surface in your containers is continually damp, you may be overwatering your plants in spite of this condition. The conventional practice is to water just after the soil surface has dried up if you do not have access to a Digital Moisture Meter or an autonomous irrigation system. Whether it’s time to water again, insert your finger at the base of the plant to see if it’s necessary.
The other preventive precaution, which is particularly important in hydroponic installations, is cleanliness of the environment.
Remove all dead plant material and clean all reservoirs, lines, and drainage holes to ensure that no organic build-up occurs in the future.
Keep in mind that the cleaner the facility, the less opportunities there are for adult fungus gnats to lay eggs.
How to Kill Fungus Gnats on Cannabis Plants?
As a beginner grower, what do you do when you notice a swarming of small bugs on the soil of your seedlings or clones that you have just potted up? There are four harmless ways to tamp down a fungus gnat infestation without harming the gnats or polluting the environment with toxic pesticides.
- Sticky fly paper: Adult fungus gnats seeking for a place to land are attracted to sticky yellow flypaper because it is sticky. This stops adult flies from mating and producing eggs, which is detrimental to their survival. Yellow flypaper strips can be placed on the soil’s surface or hung from a lower limb to attract insects. Traps are inexpensive and may be purchased at garden supply stores. Apple Cider Vinegar: Similar to fruit flies, apple cider vinegar attracts, traps, and kills mature fungus gnats. It is a natural insecticide. A tiny amount of apple cider vinegar along with a drop or two of dish soap should be placed in a shallow dish. Create a border around the base of the plants. Neem Oil:Neem oil is a tried and tested natural insecticide that is frequently used in the cannabis production industry to control pests. Spray neem oil on the surface of your soil to destroy larvae and eggs that have hatched. Moreover, this procedure can be used as a preventative precaution. Improved Air Circulation: It’s critical to make the overall atmosphere less conducive for the development of fungus gnats. Make use of fans to circulate air through the lower foliage and throughout the topsoil surface of the garden. While this will not completely remove the gnats, it is a handy addition to your arsenal.
Fungus Gnats are a Preventable Pest
Despite the fact that fungus gnats are not the most harmful insect in the cannabis garden, they are nevertheless undesirable.
You’ll want to avoid a fungus gnat infestation, which is especially important for young plants, by keeping the environment clean and avoiding the dangers of overwatering. If you catch them early enough, there will be no threat to your plants’ health.
How to Get Rid of Gnats in Cannabis Plants
A number of bugs, like us humans, are addicted to the delicious flavor of marijuana. They, on the other hand, do not have the decency to wait till the plant has finished blooming before tucking in. Fungus gnats on cannabis are one of these difficulties that might spell doom for small-scale growers’ homegrown plants. Because of their diminutive size, they can fit into even the tiniest of spaces, penetrating grow tents and rooms to gorge themselves on your labor of love and labor of love. The presence of an infestation may soon result in poorly weeded plants and less-than-impressive harvests, as well as, in certain situations, the death of your pot.
This understanding will enable you to take immediate action and prevent these uninvited guests from creating long-term damage.
We’ll look at why these creatures regard weeds to be prime real estate, how you can prevent them from setting up camp, and what to do if it’s already too late.
What are fungus gnats?
Sciarid flies, sometimes known as marijuana fungus gnats, are tiny, winged insects that make their home in soil-grown marijuana plants. They’re extremely prevalent in humid regions, and they tend to congregate in locations where there’s standing water. Adult cannabis pests, in contrast to many other pests of the cannabis plant, are not interested in eating the leaves. At this time, they simply consume liquids and feed on a limited basis. Instead, it is the larvae that are the source of all the hysteria as they nibble on the roots.
For the most part, mature plants have strong roots that allow them to endure the attack of cannabis gnats, as long as the infestation isn’t too extensive.
What do fungus gnats look like?
Cannabis fungus gnats are extremely little organisms, measuring around 2mm in length and no more than a dime when fully developed. They’re black in color, with translucent wings, and resemble a lot like mosquitoes in their appearance. The larvae are a bit bigger than the adults, developing to be about a quarter of an inch in length. Their glossy black heads and creamy colored, nearly see-through bodies make them simple to distinguish from other insects.
How long do fungus gnats live?
Cannabis gnats have a short and quick life cycle, with a total lifespan ranging between 18 and 30 days. It takes less than a week for the eggs to hatch into larvae when they are laid in moist, fertile soil. Females may lay up to 300 eggs in a single day and can lay up to 300 eggs in a single day when the soil is moist and fertile. After two weeks of consuming decaying plant waste and mulch in the soil, the maggots begin to pupate and become adults. Seven days after the pupal stage finishes, the fully grown fungus gnats that have settled on weed begin to reproduce, thereby continuing the cycle for at least one more generation.
A cannabis plant’s population of fungus gnats may increase in the blink of an eye because of their short lifespan and capacity to generate hundreds of progeny. Several generations of gnats might be living in your marijuana before the first month of the invasion has passed.
What do fungus gnats do to plants?
Unlike most other insects, cannabis gnats have a short and rapid life cycle that lasts between 18 and 30 days. It takes less than a week for the eggs to develop into larvae when they are laid in moist, healthy soil. Females may deposit up to 300 eggs in a single day in moist, nutritious soil. Approximately two weeks after consuming decaying plant materials and mulch in the soil, the maggots start to pupate. Seven days after the pupal stage finishes, the fully grown fungus gnats that have settled on weed begin to reproduce, thereby continuing the cycle for at least another seven days.
It is likely that generations of gnats will be living in your marijuana before the first month of the invasion has passed.
How to identify fungus gnats on cannabis
It’s simple to spot gnats in your grow room or tent after you’ve learned the telltale indicators that they’ve decided to take up residence in your crop. Keep a look out for the following:
- Tiny flies– Fungus gnats on marijuana aren’t very good at hiding their presence. If you have an invasion, adults may easily be seen hopping and crawling around on the surface of the plant’s soil
- If you don’t have an invasion, adults are difficult to spot.
- White maggots– It’s possible that the soil underneath your weed is home to larvae. Gently mix up the top layer of your weed to check if any new ones appear as part of your marijuana wellness practice. The presence of slime trails on the surface of contaminated soil indicates the presence of a colony when a small number of visitors transform into a large number.
Fungus gnats vs. fruit flies
Gnats on cannabis have a similar appearance to fruit flies, and they are frequently confused with them. There are some minor distinctions in their look that can be used to distinguish them from one another. For example, cannabis gnats are pale brown in color, whereas the latter are black. Fruit flies are attracted to decaying vegetables and fruits and linger around them. Gnats, on the other hand, like moist environments such as sewers, water containers, and garbage cans, just as they do. If your growing environment is clean, but you’re still surrounded by small flies, the only thing that might be attracting them must be the soil—a strong indication that they’re marijuana fungus gnats rather than fruit flies, as previously stated.
What are the fungus gnat symptoms in your plant?
It’s vital that you understand the signs of fungus gnats so that when they come knocking on your door, you can apply efficient and suitable pest control procedures to keep your weed safe. The following are some of the symptoms of fungus gnats on cannabis:
- Learn the signs of fungus gnats so that when they arrive on your doorstep, you can take efficient and suitable pest control methods to safeguard your weed. Infested cannabis plants exhibit the following symptoms:
- It’s vital that you understand the signs of fungus gnats so that when they arrive, you can take efficient and suitable pest management methods to safeguard your plants. The following are symptoms of fungus gnats on cannabis:
- Fungus gnat larval waste distributes dangerous microorganisms, resulting in a disease known as damping-off, which is caused by fungus gnat larvae waste. Because of the constant moisture in the soil, the deadly fungus take hold, weakening seedlings to the point where they fall over and die.
- Fungus gnat larval excrement distributes dangerous germs, resulting in a disease known as damping-off, which is caused by the presence of fungus gnats. The deadly fungus take root in constantly damp soil, causing seedlings to become weak and eventually fall over and die.
Why do fungus gnats attack cannabis plants?
Fungus Gnats like humid and damp environments where there will be lots of decomposing organic matter for their larvae to feed on in the soil, which is why they are so successful in cultivation. They deposit their eggs in marijuana grow facilities because they give the ideal environment and a plentiful supply of earth. Because of their lack of familiarity with watering regimens, novice growers are more likely than experienced cultivators to encounter gnats in their grow tent setup. Decomposition and fungal development are encouraged by an overwatered medium, which is also described as “a gnat’s feast on marijuana.” If cannabis fungus gnats simply devoured decomposing stuff in the soil, they would not be a significant nuisance, until their feces clogged up the drainage system, in which case they would be problematic.
Tender roots, particularly the thin hair roots of young plants, are caught in the crossfire and can cause serious damage to the health of your plant.
Do gnats kill cannabis plants?
As we now know, discovering gnats in your grow room or tent indicates that your cannabis is under attack. In order to survive larvae burrowing into their roots, seedlings and young plants must soon display symptoms of stress, which can lead to wilting and eventual death. Cannabis gnats on older plants generate nutritional deficits that have a negative influence on the long-term health of your crop as well as its ability to produce yields. Adult gnats may not be hungry for your marijuana, but they have the potential to transfer illness when they hop between plants in your crop, according to the USDA.
Fungus gnats during flowering
An infestation of fungus gnats during blooming is a major source of concern for your total harvest production. The root damage that gnat larvae cause in their wake has a negative impact on the development of plants. Cannabis roots that are not in good condition will not be able to absorb the nutrients and water that your crop requires to grow throughout blooming. As a result, bud growth is slowed, resulting in a crop of little nugs that is less than stunning in comparison to your efforts. Leaf with fungus gnats on it

Given that it is manufactured from horticultural oils, it presents no danger to either people or pets.
- Remove the top layer of soil and marijuana fungus gnats will not be able to live if their home is removed. The topsoil should be dried using fans to make it unfriendly to larvae and prevent adult hens from landing to lay any further eggs.
To kill marijuana fungus gnats, it is necessary to remove their habitat from the soil’s top layer. The topsoil should be dried using fans to make it hostile to larvae and prevent adult birds from landing to lay further eggs.
How to prevent fungus gnats?
Once fungus gnats on cannabis have taken up residence, it can be quite difficult to get them to depart the premises. Because of their high rate of reproduction, disrupting their life cycle might be a major nuisance for them. As you set up your grow area, be sure to use the following pest-prevention methods to ensure that gnats will not be able to enter your grow tent from the beginning.
- Produce a wet-dry cycle– It is vital that you pay attention to how much and how frequently you water your weed. Provide enough drainage and establish a wet/dry schedule in order to eliminate cannabis fungal gnats and a slew of other problems.
You should always allow the soil to partially dry out between watering sessions. Do the lift test to get a sense of how much your cannabis requires, and only ever offer as much as your pot can take in a matter of hours or minutes.
- Garbage, perlite, or sand can be used to block gnats from entering your crop by covering their nesting grounds.
- In order for cannabis gnat larvae to enter your grow chamber in the first place, you must sterilize your growing medium. They frequently take a trip in dirt that have been purchased from a store. When you bake the dirt in the oven, you are killing any maggots and other hazards that may be lurking inside.

Despite the fact that they have miniscule bodies and black heads, the maggots of fungus gnats seem like little worms.
What are fungus gnats?
They were given the name “fungus gnats” because they feed on fungus that grows in the soil. When they run out of soil to deal with, they begin to focus on the root systems of your plants instead. They eat away at the little root hairs and cause harm to the larger root systems. When this happens, it has an effect on the rate at which your plants develop, causes the leaves to become various hues, and causes the stems and branches to grow in an odd manner. Fungus GnatsThe most serious problem with fungus gnats is that they make your plants particularly prone to a wide range of fungal infections, making them a serious pest.
If the droppings are left in the soil, they will have an adverse effect on the drainage of your soil and will cause the soil to become too damp.

First and foremost, fungus gnats are drawn to your valued plants due to the presence of moist soil and rotting organic debris. As a result of overwatering your plants or allowing the decaying plant waste to accumulate, fungus will begin to grow on them. This is frequently difficult to detect with the naked eye, which invites fungus gnats to come feast and lay eggs in the vicinity. If you’re getting marijuana clones from somewhere else, you have to be very certain that they don’t have any fungus gnats, spider mites, or other pests on them before planting them.
The most convenient method of transferring pests to new crops is through clones, which is especially true when growing indoors.
A moist soil and decomposing organic debris are the primary factors that draw fungus gnats to your expensive plants in the first place. Therefore, overwatering your plants or allowing dead plant stuff to decompose will result in fungus growing on your plant material. The fact that this is frequently difficult to detect with the naked eye invites fungus gnats to come feast and place their eggs. Obtaining marijuana clones from another source necessitates thorough inspection to ensure that they are free of fungus gnats, spider mites, and other pests.

Fusarium Gnats and their larvae have been found in compost pile’s on a number of occasions, and it’s not uncommon to find them there. Due to the fact that compost is designed to strengthen and harden your plants rather than destroying them from the roots up, it is something that you should pay close attention to while you are composting. So, what should you do if you have a fungus gnat infestation in your compost? First and foremost, you must make certain that your compost pile is not excessively damp.
- A reasonable rule of thumb is that compost piles should not appear wet, but should have a moisture content that is comparable to that of a sponge that has been squeezed.
- You should try spreading food-grade Diatomaceous Earth over the exposed areas of your compost pile if you do happen to find those bothersome larvae in your compost.
- If the condition is extremely severe, you should consider using a pesticide that contains Bacillus thuringiensis.
- This product should be used in a dry formulation rather than a liquid formulation; break up the pieces into a finer powder and sprinkle it over your compost pile.
- Once you have allowed your compost pile to dry up sufficiently, cover it with a plastic sheet or tarp to keep it protected from the elements.
- Another method of attaining the same result is to cover it with a substance that contains a significant amount of carbon.
- If at all feasible, you should have a lid on your compost bin from the start, which will prevent the infestation from occurring in the first place.
- If you want to avoid this from happening, don’t put your food wastes in the compost pile if you’re planning on using it to grow marijuana plants.
- In order to stop fungus gnats or other pests from getting to your kitchen wastes, you should bury them in the centre of the pile.
- Furthermore, this will prevent the fungus gnat larvae from becoming too bothersome, in the event that they have already made their way into your delectable compost pile.
If the compost is properly kept, the temperature of the compost will grow dramatically. This will, at long last, burn the remaining larvae, leading them to very surely meet their end as a result.

Fungus gnats are sometimes confused with fruit flies; thus, it is important to be mindful of which insect is buzzing around your marijuana plants. Identifying the type of fly you are dealing with is critical since fruit flies and fungus gnats have quite distinct habits (and, as a result, require very different deterrents). Fruit flies have bodies that are brown, yellow, or orange in color, whereas fungus gnats have bodies that are gray, dark brown, or black in color, respectively. When you look closely at fungus gnats, you will see that they are unusually little, although fruit flies are normally bigger and easier to identify.
In addition to ripe or decaying fruit (thus their name), they are drawn to soil that has been incorrectly composted and contains your leftover cooking waste.
