Dealing with pesky gnats infesting your beautiful basket grass plants can be incredibly frustrating. But with the right techniques and a bit of patience, you can successfully get rid of gnats from your basket grass and keep them thriving.
Identifying the Problem
Before taking action against gnats, it’s important to confirm they are indeed the culprits bothering your plant. Look for small black flies hovering around the soil surface or flying around the plant. You may also notice gnats emerging from the soil when watering. This occurs because moist soil offers the perfect breeding ground for gnats.
Inspect the plant thoroughly for any signs of damage the gnat larvae may have caused like chewed leaves or roots. Catching an infestation early makes it easier to eliminate.
Reducing Excess Moisture
Since gnats need moist soil to breed, reducing moisture levels is key. Allow the top layer of soil to dry out a bit between waterings and don’t let water accumulate in the saucer under the pot. Use well-draining soil and ensure adequate air circulation around the plant.
You can also add sand or small pebbles as a top dressing to prevent gnats from laying eggs in the soil. Just make sure the drainage isn’t impacted.
Employing Natural Remedies
Several natural remedies can help kick gnats out of your basket grass plant without using harsh chemicals:
-
Apple cider vinegar traps: Fill a shallow bowl with ACV and a few drops of dish soap. The gnats get attracted to the vinegar but get trapped in the solution.
-
Cinnamon powder: Sprinkle cinnamon on the soil, which deters gnats with its smell and antifungal properties.
-
Neem oil: The natural pesticide neem oil disrupts the gnat reproductive cycle. Mix with water and spray onto soil.
-
Hydrogen peroxide: Diluted hydrogen peroxide kills gnat larvae and adds oxygen to the soil. Apply it directly to the soil.
-
Sticky traps: Traps hung near the plant catch adult gnats before they can reproduce. Avoid contact with the leaves.
Removing Infested Soil
For severe infestations, removing the top few inches of soil may be needed. Use caution to avoid damaging roots. Discard the infested soil in a sealed bag and replace with fresh, sterile soil. Repotting into clean containers also helps give the plant a fresh start.
Isolate repotted plants from original locations to prevent gnats from returning. Monitor closely for reinfestation.
Maintaining Proper Plant Hygiene
Prevention is crucial when dealing with gnats. Be diligent about:
-
Removing fallen leaves, debris, and weeds around plants that offer gnat hiding spots
-
Inspecting plants routinely for pests
-
Avoiding over-fertilization that can cause excess moisture attractive to gnats
-
Letting soil dry out adequately between waterings
-
Providing good airflow and drainage
-
Cleaning pots and trays thoroughly to eliminate eggs and larvae
Why Gnats Attack Basket Grass
Gnats target basket grass plants for some specific reasons:
-
The moist, organic potting mix used for basket grass offers an ideal nursery for gnat larvae.
-
The leafy foliage provides shelter for adult gnats.
-
Basket grass grown as indoor plants or in greenhouses lack natural predators like birds that would feed on gnats.
-
Overwatering and poor drainage allow moisture levels to become excessive.
Preventing Reinfestations
Getting rid of gnats in basket grass requires persistence. After treating an infestation, continue taking preventive measures to ensure the pests don’t return:
-
Allow soil to dry out between waterings
-
Eliminate other breeding grounds like damp pile of leaves or compost
-
Use yellow sticky traps continuously to catch adult gnats
-
Introduce natural predators like ladybugs or green lacewings
-
Replace potting mix annually to remove gnat eggs
-Space plants adequately to encourage air flow
When to Seek Expert Help
In rare cases, gnat infestations can get out of control. If you notice rapidly multiplying gnats, extensive damage to your basket grass, or if the infestation spreads to other plants, consider consulting a horticultural specialist. They can identify the specific gnat species, pinpoint the source, and recommend commercial-grade treatments if needed.
With persistence and preventive care, you can reclaim your beautiful basket grass plant from invasive gnats. Pay close attention to moisture levels, use natural remedies liberally, remove badly infested soil, maintain cleanliness, and stay vigilant against reinfestations. Your diligence will soon reward you with a lush, thriving basket grass garden free of annoying gnats.

How to Get Rid of Fungus Gnats
I tried several methods to kill my herd of intruders before I finally found a solution. But first, here are some frequently-mentioned remedies that didnt work for me or were just too inconvenient to try:

Apple Cider Vinegar
Every time I’ve looked up a method to get rid of fungus gnats or fruit flies, the mixture of apple cider vinegar, dish soap, and water is always at the top of the list – and it has NEVER worked for me. This time was no exception.
It seems like the smell is just as obnoxious to the bugs as it is to my nose, and no one wants to go near the stuff.
Neem Oil & Other Sprays
Neem oil is a naturally occurring pesticide and came up frequently as an option to rid my life of fungus gnats, so I gave it a whirl. But I had some issues with it.
First of all, the suggested application was to drench my plants in neem oil – including the tops AND bottoms of leaves as well as the stems. This proved to be a really messy endeavor, especially when dealing with an oily substance.
On top of that, although the smell isn’t super strong, I definitely wasn’t a fan. Needless to say, this method didn’t work either.
I also tried other sprays that claimed to kill fungus gnats but to no avail.
Waiting Longer Between Waterings
Because fungus gnats thrive off the decaying material in soil, which is exacerbated by dampness, the idea behind this method makes sense. This seemed to work in the short term, but I ended up needing to water my plants before they died and the gnat problem picked right back up.
Drench in Water
I realize this remedy seems counterintuitive to the recommendation above. Let me explain.
The idea isn’t to just water your plants into oblivion, but rather to either put them in the shower and give them a good spray or dunk them in a bath to wash away the pests.
The problem here is that A) not all of my pots have drainage holes or nursery pots (something I’m working on switching out, don’t @ me), and B) it’s unlikely that this would wash ALL the larvae away. I didn’t even bother giving this idea a try.
Repotting
I have A LOT of plants, so it would have been wildly inconvenient to repot them all, but if you only have a couple this would be a viable option. Just make sure you throw out the old soil and maybe give your plant a good rinse before repotting.
Will Fungus Gnats Hurt My Plants?
Aside from being unbearably annoying, adult fungus gnats wont directly harm your plants. I say “directly” because their offspring most definitely can.
Fungus gnat larvae survive by eating fungi, organic matter in the soil, and the roots of plants, which can cause damage.

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.
Does letting soil dry out prevent gnats?
Unless you’re dealing with moisture-addicted plants (something like a maidenhair fern, a true drama queen), letting at least the top of the soil dry out is not a problem. It doesn’t just help prevent gnats, but also lessens the chances of deadly root rot and other problems taking hold. It’s all about finding that balance!
Do fungus gnats like dry soil?
Use a chopstick to carefully poke into the medium, moving it around a little to create air pockets and allow water to penetrate deeply but drain easily. Repot every one to two years, as overly decayed soil can become compacted. Okay, so now you know that fungus gnats love damp soil. Dry soil would prevent infestations, but our plants do need water.
