What Attracts Gnats?

Understanding the factors that attract gnats to your home is the first step in answering the question: “How do I get rid of gnats in house”? Here are some common attractants:

Overripe Fruits and Vegetables

Gnats are highly attracted to the aroma of overripe or rotting fruits and vegetables. They lay their eggs in these decomposing organic materials, creating a breeding ground for future generations of gnats.


North Carolina's warm and humid climate provides the perfect breeding conditions for gnats. Excess moisture in and around your home, such as damp soil, wet houseplants, or leaky pipes, can attract gnats looking for breeding sites.

Sweet or Fermented Liquids

Gnats are also drawn to sweet or fermented liquids like sugary beverages, wine, and vinegar. Leftover residue in glasses or bottles can attract gnats, as can spills and drips in your kitchen or dining area. Homeowners who notice gnats in their kitchen can usually trace it back to sinks and dishwashers because of this. 

Where Do Gnats Come From?

Before you can get rid of gnats in houses in North Carolina, you have to know where they’re coming from. Gnats typically come from the following sources:


Gnats are outdoor insects that can find their way inside through open doors, windows, or small cracks and gaps. They are more prevalent in outdoor areas with moist soil, decaying vegetation, or standing water.

Breeding Sites

Gnats lay their eggs in moist or decomposing organic matter. Gnats in plants are a common observation by homeowners, as well as in and around trash cans with organic waste, and clogged drains. Identifying and eliminating these breeding sites is crucial in controlling gnat populations.

How to Get Rid of Gnats

To get rid of gnats in house, there are a few common and effective methods you can employ. Of course, the quickest and most effective way is with the help of a pest control professional, but it may be worth it to also try some of the following: 

1. Remove Attractants

The first step is to remove attractants that may bring more gnats indoors. Discard overripe fruits and vegetables promptly, and clean up spills and crumbs in the kitchen and dining areas. Make sure you store sweet and fermented liquids in sealed containers, and keep trash cans tightly sealed and empty them regularly.

2. Improve Ventilation

Next, ensure proper ventilation in your home by using screens on windows and doors.

Use fans to improve air circulation, which can deter gnats from settling indoors.

3. Eliminate Breeding Sites

Breeding sites are places where gnats multiply, so you’ll want to get rid of those wherever possible. Get rid of gnats in plants by regularly checking and watering your indoor plants, ensuring they do not become waterlogged—it’s also best to empty and clean drip trays under potted plants.

You should also keep drains clean and free from organic debris, and seal any cracks or gaps in walls, windows, and doors to prevent gnats from entering.

4. Natural Repellents

Before you just walk into your local home improvement store on the hunt for the harshest “gnat killer indoor” product, try natural repellents that are less likely to pose a risk to your family and pets. 

Place bowls of apple cider vinegar or red wine with a few drops of dish soap near gnat-infested areas. The gnats will be attracted to the liquid and trapped by the soap.

Citronella candles and essential oils like lemon eucalyptus can also help repel gnats.

5. Insect Traps

On top of repellents to get rid of gnats in house, you can also employ insect traps. Use store-bought versions, or create DIY traps using sticky tape or jars filled with vinegar and a drop of dish soap.

6. Professional Pest Control Services

If your gnat infestation persists, and you still find yourself frustratingly googling “how to get rid of gnats in my house”, consider hiring a professional pest control service like those at A-1 Pest Control to assess the situation and provide tailored solutions.
