Oh. My. Goodness. I HATE fungus gnats. And thats from someone who dislikes using the word hate. And Ive put it in capitals. Yep. That much.
When I first started collecting plants I was quickly over-run by Fungus Gnats. And because they love carbon dioxide, the only thing more appealing to them than the moist soil of my plants, was the CO2 in my breath, so you always know when you have Fungus Gnats.
Even one or two adults and theyll quite literally be all up in your face. Plus I couldnt leave a cup of tea uncovered without finding little unwanted floaters, and I really love my tea. They had to go…

Everything helped a little, some more than others (and the cinnamon smelt lovely when I watered), but nothing totally eliminated them, they only reduced the population a little. Simply watering less helped also, although I did take it a bit far and ended up almost losing some plants, so had to find a solution that didnt compromise my plants health.
What DID get rid of Fungus Gnats entirely for me in the end, was this simple two step method below. Thats not to say this is the one-and-only method. Just the one that finally worked for me once and for all.
As an owner of the graceful Abyssinian banana tree, few things are more annoying than an invasion of tiny gnats swarming your prized plant. While these pests may seem harmless, left unchecked they can seriously damage your banana tree’s health. Don’t despair – with some diligent effort, you can banish gnats for good. This comprehensive guide covers everything you need to know about eliminating gnats in Abyssinian banana trees.
Understanding Gnat Behavior and Impact
Before tackling a gnat problem it’s important to understand what attracts them and the potential risks they pose. Gnats, also known as fungus flies are drawn to moist environments rich in decaying organic matter – the perfect description for potting soil. Female gnats lay hundreds of eggs in the soil, where larvae hatch and begin feasting on plant roots and fungi. This feeding damages roots, stunting the plant’s growth. Adults then emerge and begin the cycle again. With their rapid reproductive rate, gnats can get out of control quickly.
For Abyssinian banana trees, whose large leaves and fast growth create ideal gnat habitat, infestations must be addressed immediately Left uncontrolled, these tiny pests could seriously compromise your plant’s health and appearance Don’t wait – implement control measures as soon as gnats are spotted.
Effective Gnat Control Methods
Fortunately, there are many effective options for ridding your Abyssinian banana tree of troublesome gnats. Here are the top methods recommended by experts:
-
Let soil dry out completely between waterings. This removes the moisture gnats need to reproduce. Be sure to water thoroughly when needed.
-
Use yellow sticky traps. These traps lure adult gnats looking for a place to lay eggs. Place several near infested plants.
-
Repot with sterile soil. Discard old soil which likely contains gnat eggs and larvae. Repotting in sterile soil gives a fresh start.
-
Apply neem oil drench. The organic neem oil disrupts the gnat life cycle and kills larvae in soil. Drench soil to eliminate infestations.
-
Introduce beneficial nematodes. These microscopic worms prey on gnat larvae in soil. Apply as directed for biological pest control.
-
Improve air circulation. Stagnant air encourages gnat populations. Use fans to keep air moving around plants.
-
Remove decaying plant matter. Clear away fallen leaves/debris where gnats may breed. Keep area clean.
-
Use diatomaceous earth. Sprinkle this abrasive, desiccant powder over soil to shred and dehydrate larvae.
Preventing Future Gnat Problems
Once gnats have been eliminated, maintaining gnat-free plants requires diligence and preventive care including:
-
Monitoring soil moisture closely to prevent overwatering
-
Inspecting new plants extremely thoroughly before bringing home
-
Sterilizing pots and trays to eliminate spores, eggs and larvae
-
Avoiding organic mulches which can harbor gnats
-
Letting soil dry out completely between waterings
-
Removing plant debris promptly
-
Fixing drainage issues
-
Allowing proper airflow around plants
With persistence and dedication to prevention, you can keep gnats away from your Abyssinian banana tree for the long term. Don’t tolerate these irritating pests – implement a multipronged approach to eliminate gnats and maintain a pest-free environment. Your efforts will pay off with a healthy, thriving banana tree.
Do Fungus Gnats harm your plants?
If you get on top of them while the infestation is small, the good news is they are more annoying to you than harmful to your plants. Even in large numbers, its not the adults you need to worry about, its the larvae. Its rare, but in large numbers when larvae run out of yummy organic matter to eat in your soil, theres a risk they may chomp on your plants roots.
Fungus Gnats love warm, moist conditions, so if you tend to water too often or keep the soil moist, and its a warmer time of year, thats a big yes please from fungus gnats. A bad infestation can continue right through winter, so just waiting it out often wont work. When Fungus Gnat larvae do feed on your plants roots, that can stunt plant growth, particularly in seedlings, newly rooted cuttings and younger plants.
How do you use mosquito bits to kill fungus gnats?
The brand I use available locally is called Mozzie Bits made by EasyTrap, but these directions are the same if youve got Mosquito Bits from Amazon. The box gives you the directions for larger areas of water based on surface area. Thats because – like the name suggests – you can use them for mosquito control in areas like ponds and water tanks. But used for fungus gnats for indoor plants, I use the same method plant YouTubers have nicknamed Mozzie Tea.

Here’s how to use it: Step 1: Dilute the hydrogen peroxide with water at a ratio of 3 teaspoons of hydrogen peroxide to 1 cup of water. Step 2: Add the mixture to a spray bottle. Step 3: Spray your plant with the mixture twice a week until the gnat infestation clears up.
How do you stop Gnats from laying eggs?
Use a fine layer of sand or diatomaceous earth on top of plant soil to deter gnats from laying eggs. Use well-draining pots and soils. Inspect new plants for gnats before buying them. Seal cracks and holes around doorways, windows, and drains to prevent gnats from entering. Clean up damp places and allow them to dry.
How often should I fertilize my Abyssinian banana plant?
Fertilize every two weeks to satisfy the heavy feeding habits of the Abyssinian banana plant. Use a balanced fertilizer for the banana plant. You can also use a slow-release fertilizer four times per year to nourish the plant. Remove any leaves that droop or are damaged, taking care not to cut the main stem.
