Ways to Get Rid of Fungus Gnats of Monstera Plants- Monstera Gnats

Even if you are being careful and diligent, it’s still possible to run into a pest infestation problem. Trust me, it’s a true situation. However, monstera plants are not among the houseplants most susceptible to insects.

By reading this statement, it does not mean they are not prone to any disease or pests because they can get infested or suffer from fungal diseases.

My monstera plants were suffering from fungus gnats, and I did everything to save the plants without researching what was causing them to die. So, I don’t want you to go through the same struggle. That’s why I have explained the common insects so that you can recognize them and try to get rid of them accordingly. In the future, if you have any doubts, you can ask me in the comment section.

About Fungus Gnats:

You can recognize the Fungus gnats by their long legs transparent wings and affinity for nutrient-rich, moist soils. They are used to buzz around the plant container but don’t munch on the plant Foilage directly just like the other harmful pest do. You can find them in the soil, feasting on the plant root and the organic matter such as rotten fruit. Make sure not to leave the plant untreated because they can still cause a considerable amount of damage to the plant.

There is one more pesky insect that can cause environmental problems such as the drain fly which has the same appearance as fruit flies. They are small fuzzy insects that used to thrive in damp and decaying organic matter which you can find in and around drains,  sewage systems, and compost piles. 

If they get indoors it will become a nuisance, especially in the bathroom and kitchen where they are used to laying eggs in the gelatinous film found in drain pipes. If you don’t read them on time they get to multiply rapidly and will create problems for the homeowner.

The aged fungus gnats do have a lifespan of about a week and are eligible to make a significant impact in a short period such as laying up to 300 eggs when everything is provided to them in the right condition. They are considered to have the fastest turnaround and short life cycle of 3 to 4 weeks in short the population multiplied pretty quickly so it is important to take action against them when you notice their infestation on your house plant

Maintaining Cleanliness

Regularly inspecting and cleaning your monstera plants can help prevent pest issues. Remove any dead leaves or debris and quarantine new plants before introducing them to your collection to minimize the spread of pests.

Biological Control Methods:

Using the biological controlling methods is an environmentally friendly way to manage fungus gnats on monstera plants. They are effective in reducing infestation and avoid the use of harsh chemicals. Here I have mentioned two popular biological methods for controlling fungus gnats on monstera plants.

Introducing Beneficial Insects:

  • The ladybugs and lacewings are the insects that prey on gnats and larvae.
  • Using these insects will help you to curb gnats infestations and also help in maintaining a balanced ecosystem.
  • In order to attract these helpful insects you need to consider adding insect-friendly plants.

Using Nematodes:

  • They are used to penetrate larvae by releasing bacteria and causing larvae to demise.

Chemical Solutions:

You can also eliminate the fungus gnats of monstera plants by applying various chemical solutions. Here I have explained the way to apply insecticides and use fungus gnat predators.

Applying Insecticides:

Using insecticides is considered an effective method for controlling gnat infestation such as:

  • Insecticidal soap: It is considered a natural option for controlling pests such as aphids, mealybugs, spider mites, and white flies. Use the soap by spraying it directly on the affected areas of monstera plants.
  • Neem oil: The neem oil drive from neem trees that can deter gnats and other pests. To use it you need to mix the neem oil with water as per mentioned in the instructions on the label and spray the solution on the monstera plant and soil surrounding it.
  • Horticultural oil: Using horticultural oil will suffocate pests by creating a thin film that covers the gnat’s body and making it difficult to breathe. You need to apply horticultural oil on the monstera plant by spraying it.
  • Pyrethrin and pyrethroid insecticides: They are very effective in working against pests like fungus gnats. You need to apply the insecticides on the plant according to the instructions mentioned in the product.

Make sure to follow all the product instructions carefully and always take all the precautions that will help to protect the plant and environment too.

Using Fungus Gnat Predators:

Many biological control methods help in reducing the fungus gnat on Monstera plants. Here I have mentioned a list of natural predators of fungus gnats Which is an eco-friendly way to keep the pest away:

Bacillus thuringi ensis subspecies israelensis (Bti): 

  • It is a biological control agent that can be used against the fungus Gnats.
  • They are present in specific products used to control gnats such as mosquito dunks or bits.
  • You need to follow all the instructions mentioned on the product to apply it on Monstera soil.

Hypoaspis miles (predatory mites):

  • The predatory mites are used to feed on fungus Gnats larvae and soil-dwelling pests.
  • To control the growth of monstera plants need to use hypoaspis miles which help them to control gnats populations.

Nematodes:

  • You can add nematodes for example steinernema feltiae into the soil that will kill fungus gnat larvae.
  • Make sure to follow all the product instructions for applying nematodes on Monstera plant soil.
  • You can use it to control in conjunction with others that will effectively manage gnat infestations and help to keep your plant healthy.
