Get Rid Of Fungus Gnats

Updated: Jun 7

Fungus gnats are very common pests in indoor plants around the globe. They are attracted to damp and natural space, where fungi like to grow. Homes to plants like greenhouses, forests, and even inside homes are prime locations for these little black bugs to thrive, as they have loads of nutrients to survive.

Fungus gnats breed rapidly, with 100 to 150 eggs laid by a single gnat in one week! Because their numbers can multiply, they easily over-take their natural habitat and can be a pain to eradicate. The key to handling fungus gnats is by creating preventative treatment and equipping yourself with the knowledge to remove them quickly.

What buzzes but doesn't bit? Eats your plants but loves them as much as you do? And breeds so quick you can't catch them? Fungus Gnats

Fungus gnats love moist soil. So the first step to getting rid of fungus gnats is reducing the number of times you water your plants.

Let the soil dry out between watering!

Why? Gnats love warm, wet environments and indoor plants are their dream home.

Tip: Try bottom watering your plants (read this blog for guidance) or letting a finger-length of topsoil dry out before you water.

If this doesn't stop the infestation, it'll slow it down, giving you time to react.

The next step will be to find and separate the infected plants.

Isolate the infected plant.

Read this blog to help identify what fungus gnats look like and where to find them. Once you know where they are and in which plants they're breeding, quarantine that plant. Isolating them will stop the gnats from flying from plant to plant.

Please close the door and leave them for a week.

Spray neem oil on the topsoil of the plants to suffocate the gnat larvae.

Invest in stick traps.

Sticky traps are the only natural way to kill adult fungus gnats. Gnats are attracted to sticky traps by scent or colour, and once landed, they can't get away. They're trapped.

Adult fungus gnats live for a week a during that time will lay 100 to 150 eggs. If they're trapped, they can't breed anymore.

You could also invest in a carnivorous plant to lure in the tiny plant pests, but they can only catch a certain amount till they're full (they're also tricky to keep alive).

Create a barrier with sand or gravel

The final simple trick is to create a barrier above the soil that fungus gnats can't climb through. Again, sand is excellent; the small granules clump together, and gnats can't crawl through it to get to the soil.

Sand will prevent gnats from getting in and out of the soil!

The dry substrate robs the gnats of the option to breed in the soil. They can't get down to it, and their larvae can't escape upwards either.

You'll need to make a reasonably thick layer and only bottom water (watering from the top will disrupt the sand, opening it up for gnats).

There is one downside to sand; it's a pain when it comes to repotting your plant.

Reporting your plant is the last resort.

Please don't do it unless you have to. An infected plant will have damaged roots, and you don't want to upset it by moving its home.

Take care if you're repotting the plant and keep the neem oil and sticky traps on hand. One gnat can restart the whole infestation.

Gnats are one thing you need to learn to handle if you want to own indoor plants. They're very comment, and nursery plants are notorious for having fungus gnats.

Always keep neem oil and sticky traps on hand because when one gnat flies by, hundreds are already growing under the soil.

I hope that helps you get rid of fungus gnat. Let me know if you have any questions.

Keep growing,
