How to Kill Fungus Gnats
You’ve spotted them fluttering around your plants, tiny black insects that seem harmless at first. Are they mosquitoes? Harmless little unidentifiable flies?
No, they’re none other than fungus gnats. And make no mistake, fungus gnats can cause plenty of frustration. These pests thrive in moist soil and quickly infest houseplants, causing significant damage to plant health and leaving homeowners extremely frustrated.
Whether you’ve recently noticed fungus gnats in your house or they’ve been a persistent issue, knowing how to deal with them is key to keeping your indoor space pest-free.
The good news? Fungus gnats in the house might be a nuisance, but they’re not unbeatable. With some know-how and the right strategies, you can banish these pesky insects for good.
Without further ado, here’s a guide on how to kill fungus gnats in the house.
What Are Fungus Gnats and Why Are They in Your House?
First off, it’s worth understanding what fungus gnats are and why they settle in your space to begin with. These tiny flies are often mistaken for fruit flies, but they’re an entirely different pest.
Fungus gnats are attracted to moist soil and decaying organic material, which makes overwatered houseplants their favorite habitat. They lay their eggs in damp soil, and their larvae feed on fungi, roots, and organic matter.
What brings them into your home? Typically, it’s one of the following reasons:
- Damp indoor plant soil
- Overwatering your houseplants
- Poor drainage in plant pots
- Infested potting soil
Fungus gnats thrive in these conditions and, if left untreated, can spread quickly from one plant to another. The adults don’t cause much harm to plants, but their larvae can damage roots, leading to wilting or stunted growth.
Ready to find out how to kill fungus gnats and prevent them from coming back? Here are some tips:
Stop Overwatering Your Plants
One of the easiest ways to eliminate fungus gnats is to cut off their breeding ground. Overwatered plants are basically an open invitation for gnats, so it’s time to adjust your watering habits.
Make sure to only water houseplants when the top inch of soil feels dry. Use pots with proper drainage, and empty saucers promptly to avoid standing water. Drying out the soil between watering sessions disrupts the gnats’ ability to reproduce.
Not sure if you’re overwatering? Here’s a trick: Stick your finger into the top layer of soil. If it feels wet or soggy, hold off on adding water. Monitoring moisture levels helps keep pests at bay.
Add Beneficial Solutions to the Soil
When it comes to fungus gnats, not all solutions involve chemicals. Introducing natural deterrents is an effective and safe way to reduce their population. Beneficial nematodes, for example, are microscopic organisms that can attack the larvae in your soil without harming plants. They’re a great weapon to have in your pest-fighting arsenal.
Another highly effective option is Bacillus thuringiensis israelensis (BTI). Available in products like mosquito dunks, BTI targets gnat larvae and prevents them from maturing into adults. Simply crumble a bit of dunk into your plant’s water, and it’ll do the work of eliminating larvae in the soil.
These natural solutions safeguard both your plants and the environment, allowing you to fight fungus gnats without worry.
Use Sticky Traps to Eliminate Adults
Sticky traps are like flypaper for fungus gnats. These small, bright yellow traps attract adult gnats and stop them in their tracks (literally). Place the traps close to infested plants where gnats are buzzing around.
While sticky traps won’t eliminate a fungus gnat infestation on their own, they are an effective tool for quickly reducing the population of adult gnats. When combined with other measures like treating the soil and adjusting watering habits, they can help you get a handle on the situation fast.
You can find affordable sticky traps online, at garden centers, or even make your own using sticky tape and bright yellow paper.
Replace Infested Soil if Needed
If fungus gnats are still lingering despite efforts to dry out and clean up your plants, it might be time for more drastic action, replacing the soil altogether. Fungus gnat eggs and larvae can remain hidden in the topsoil, so swapping out that layer can make a big difference.
When repotting, dispose of the old soil responsibly and give your pots a good rinse before adding fresh, gnat-free soil. Consider using sterile potting mix to reduce the chance of reintroducing pests. This step is especially useful for plants with severe infestations.
Keep Your Home Clean
Beyond just dealing with your plants, maintaining a clean home can help prevent new infestations from taking root. Take these precautions to avoid reintroducing fungus gnats:
- Dispose of organic debris like fallen leaves promptly.
- Keep trash bins sealed and take them out regularly.
- Vacuum and clean areas where gnats may lay eggs.
A clean home is less inviting to pests of all kinds, including fungus gnats. It’s one of the simplest habits you can adopt to stop these invaders.
