Dealing with Fungus Gnats – Naturally!

We’ve all been there—you’re lovingly tending your heirloom tomatoes or coaxing your heritage peppers into production when suddenly, a cloud of tiny black gnats takes off from the soil. Fungus gnats! These little pests can quickly become a nuisance, but don’t worry; we’ve got you covered with some natural, eco-friendly solutions to keep your garden thriving and gnat-free.

Why Are They Here?

Fungus gnats are attracted to damp, organic-rich soil, making them a common problem in gardens and greenhouses—especially if you’re growing in containers or starting seeds indoors. Their larvae feast on decaying matter, fungi, and sometimes even plant roots, which can spell disaster for your precious seedlings.

Preventing Fungus Gnats Before They Start

Prevention is always better than cure, so here are a few steps to make your garden less appealing to these pests:

• Let the Soil Dry Out – Fungus gnats thrive in moist conditions, so allow the top couple of inches of soil to dry between waterings. Your plants will appreciate the aeration, too!
• Use a Gritty Mulch – A layer of sand, fine gravel, or crushed eggshells on top of the soil creates a barrier that deters adult gnats from laying eggs.
• Avoid Overwatering – Soggy soil is a breeding ground for fungus gnats, so always check soil moisture before watering.

Natural Remedies for an Infestation

If you already have fungus gnats buzzing around your garden, try these eco-friendly solutions to send them packing:

• Sticky Traps – Yellow sticky traps placed near plants will catch the adults before they have a chance to reproduce.
• Beneficial Nematodes – These microscopic soil dwellers seek out and destroy gnat larvae, offering a long-term solution without harming your plants.
• Neem Oil Drench – A diluted neem oil solution can help kill off larvae in the soil while also acting as a natural fungicide.

• Apple Cider Vinegar Traps – A small dish of apple cider vinegar with a drop of dish soap attracts and drowns adult gnats.

A Garden Free from Gnats!

With a little patience and a few simple changes, you can send fungus gnats packing without resorting to harsh chemicals. Your heirloom veggies and heritage blooms will thank you for it! Happy growing!
