How to Stop Gnats in Their Tracks: Effective Solutions for a Pesky Problem

Gnats can be a pesky problem for homeowners and gardeners alike. These small flying insects can quickly infiltrate your living space and create a nuisance. While annoying, gnats do not generally pose a health risk, but they are a sign of potential issues with your living area. Let’s look at how to stop gnats in their tracks with effective solutions.

Different Types of Gnats

Before we get into the solutions, it’s important to know the different types of gnats that could be infesting your home or garden.

Fungus Gnats

Fungus gnats are tiny flying insects that are attracted to bright light and moist conditions. They are a common problem for gardeners and indoor plant enthusiasts. These gnats lay eggs in damp soil and feed on fungus and organic matter found in the soil.

Drain Flies

Drain flies, also known as sewer gnats or moth flies, are small flying insects that are attracted to stagnant water and organic matter. These gnats lay eggs in the buildup of organic matter found in drains and pipes. They are commonly found in kitchens and bathrooms.

Eye Gnats

Eye gnats, also known as sand flies, are tiny flying insects that are found primarily in warm, dry climates. These gnats are attracted to moisture and can often be found in and around the eyes of humans and animals.


The best way to stop gnats from invading your home or garden is to prevent them from entering in the first place. Here are some prevention methods:

Eliminate Standing Water

Standing water is a breeding ground for gnats. Be sure to eliminate any standing water around your home or garden, including in bird baths, pet bowls, and flowerpots.

Properly Store Food

Gnats are attracted to organic matter, including food. Be sure to properly store food in sealed containers to prevent them from being attracted to your kitchen.

Clean Drains

Regularly cleaning your drains can help prevent drain flies from laying eggs in the buildup of organic matter found in pipes and drains. Use a drain cleaner to flush out any debris and buildup.

Properly Ventilate Your Home

Gnats thrive in moist environments. Proper ventilation can help reduce moisture levels in your home and prevent gnats from breeding.


If you already have a gnat problem, here are some effective solutions:

Use Pesticides

There are a variety of pesticides available that can effectively kill gnats. Be sure to follow the instructions carefully and use gloves and protective gear while applying any chemicals.

Use Sticky Traps

Sticky traps are a non-toxic method of capturing gnats. These adhesive traps can be placed around your home or garden and will attract and trap gnats.

Use Essential Oils

Essential oils such as peppermint, lavender, and citrus can repel gnats. Dilute a few drops of the oil with water and spray around your home or garden to deter gnats.

Use Vinegar

Vinegar is acidic and can kill gnats on contact. Fill a shallow dish with apple cider vinegar, cover with plastic wrap, and poke small holes in the wrap. Gnats will be attracted to the vinegar and become trapped in the dish.


Gnats can be a source of frustration for homeowners and gardeners, but they can be effectively eliminated with the proper prevention and treatment methods. Remember to eliminate standing water, properly store food, clean drains, properly ventilate your home, use pesticides, sticky traps, essential oils, and vinegar. With these solutions, you can stop gnats in their tracks and enjoy a pest-free environment.
