How to Get Rid of Gnats in House

Just the word “gnat” can make most North Carolina homeowners cringe. These tiny, flying pests seem to appear out of nowhere—hovering around fruit bowls, sinks, and potted plants. But where do gnats come from? If you're curious what attracts gnats, you're in the right place. In this post, our Western North Carolina pest control experts are helping you understand what attracts gnats and how to prevent future infestations in your home.

What Attracts Gnats?

Gnats are primarily attracted to moisture, organic matter, and anything sweet or fermenting. They thrive in environments with where they have plenty of breeding sites and decaying materials. Here are the most common sources of attraction:

Overripe Fruits and Vegetables

Fruit bowls filled with rotting or overripe produce are one of the most common gnat hotspots. The sweet scent and decaying organic matter make perfect feeding and egg-laying sites. Keep fruits refrigerated when possible and discard spoiled produce promptly.

Moisture and Damp Soil

Excess moisture from leaky pipes, wet rags, or overwatered plants can attract gnats. Fungus gnats are especially drawn to damp soil in potted plants, where they lay eggs near the roots. Allow your soil to dry between waterings to deter them.

Sweet or Fermented Liquids

Sweet drinks, wine, vinegar, or juice residue in cups and bottles attract gnats quickly. Even a little sugar or fermentation can cause a gnat infestation near sinks or trash cans. Clean spills immediately and keep beverages in sealed containers.

Garbage and Drains

Clogged drains, garbage disposals, and dirty trash cans harbor food scraps and moisture that attract both drain flies and gnats. Rinse drains weekly with a mix of apple cider vinegar, baking soda, and boiling water to break up buildup and organic debris.

Outdoor Breeding Sites

Outside your home, standing water, compost piles, and damp mulch create ideal breeding grounds for gnats and biting midges. Regularly empty birdbaths, unclog gutters, and keep your outdoor space free of decaying vegetation to prevent more gnats from moving indoors.

Common Types of Gnats Found Indoors

Now that we've explored what attracts gnats, let's talk about the most common gnats you'll find indoors. Several small fly species are commonly mistaken for gnats. Identifying which one you have helps you choose the right solution.

Fruit Flies

These small flies, such as gall gnats, are commonly found around fruit bowls, garbage disposals, and wine glasses. Fruit flies are attracted to fermenting liquids and decaying fruit and are quick to multiply if not controlled.

Fungus Gnats

Fungus gnats thrive in damp soil and are often found near indoor plants. Their larvae feed on plant roots, damaging your greenery. Letting soil dry out and adding sticky traps around potted plants can help reduce populations.

Drain Flies

Drain flies (also called moth flies) breed in the slime buildup inside sink or shower drains. Regular cleaning and using a vinegar trap can significantly cut down on their activity.

How to Get Rid of Gnats

Now that we've explored what attracts gnats, let's discuss how to get rid of those pesky insects. If you’re dealing with an ongoing gnat problem, you can take these proven steps to eliminate them and keep them from coming back.

1. Remove Attractants

Clean up any spills or food residue and discard old produce. Empty trash cans frequently and wipe them down with disinfectant. Keep drains clear and store food in airtight containers.

2. Use Vinegar or Fruit Traps

Create a simple DIY gnat trap by mixing apple cider vinegar and a few drops of dish soap in a small bowl. Cover it with plastic wrap and poke tiny holes so gnats can enter but not escape. The vinegar’s sweet scent lures them in, and the soap breaks the surface tension to trap them.

3. Try Sticky Traps

Sticky traps are an easy, mess-free option to trap gnats around houseplants, windows, or fruit bowls. Replace them every few weeks to maintain effectiveness and reduce gnat populations.

4. Eliminate Breeding Sites

Empty and scrub drains weekly, rinse recyclables before storing, and clean under appliances where moisture and crumbs collect. Check potted plants for excess water and clean out breeding sites like compost bins and pet dishes.

5. Use Natural Repellents

Try burning citronella candles or using essential oils such as lemon eucalyptus or lavender to repel gnats naturally. These scents mask the sweet odors that attract gnats indoors.

6. Call a Professional Pest Control Service

If home remedies don’t solve the issue, you may be dealing with a deeper gnat infestation. A professional pest control expert from A-1 can inspect your property for free, identify the species, and apply safe, targeted treatments to get rid of gnats.

Frequently Asked Questions

Gnats are attracted to food waste, moisture, and light. Common sources include kitchen drains, trash cans, compost, and houseplants. The combination of warmth and humidity indoors can make infestations worse during summer months.

What attracts gnats in your home? Gnats are drawn to sweet scents, decaying organic matter, fruit, and damp environments. Fruit flies prefer ripened produce, while fungus gnats prefer moist soil and plant roots.

While most household gnats don’t bite, they can contaminate food and spread bacteria. Some species, like biting midges or no-see-ums, can cause skin irritation with their bites.

Set up multiple vinegar or fruit traps near problem areas and clean all drains immediately. Removing attractants while using traps is the fastest way to reduce activity.

Maintain a dry, clean home environment. Clean drains, control moisture, and monitor potted plants to stop gnats before they breed. Routine visits from a pest control professional can help ensure long-term prevention.
