Common Types of Gnats

The term “gnat” represents a range of species of tiny, two-winged flying insects, meaning there are various types of gnats that infest homes throughout the United States. Here are four of the most common gnats you may be facing in your home:

6 Ways to Eliminate Gnats

Here are six methods to try if you need to eliminate gnats in your home:

  1. Place Sticky Traps
  2. Trap Them With Apple Cider Vinegar
  3. Use Your Fresh Fruits or Red Wine
  4. Turn on Your Fan
  5. Clear Your Drains and Garbage Disposal
  6. Hire an Exterminator

Place Sticky Traps

As an easy first step to take care of your gnat problem, you can spend roughly $5 to $10 on sticky traps to place in areas you’ve seen the insects flying around. They typically can last for a few months and are baited with a solution that attracts the gnats then traps them with a sticky substance.

Trap Them With Apple Cider Vinegar

One of the most popular do-it-yourself (DIY) gnat removal methods is the homemade apple cider vinegar trap. It’s a simple strategy of attracting the gnats or fruit flies with food, then trapping them by blocking their exit with a paper cone or plastic wrap.

Here’s how it works:

  1. Fill a small glass, bowl, or jar with a few tablespoons of apple cider vinegar and a drop of liquid dish soap.
  2. Roll up a piece of paper into a cone shape and place it with the small part of the cone touching the bottom of the inside of the container.
  3. Alternatively, you can put plastic wrap over the top of the container and poke a few holes with a toothpick.
  4. Gnats attracted to the sweet solution will enter through the side of the cone or the holes in the plastic wrap, and they won’t be able to escape.
  5. Change out the solution every day or two to maintain its potency.

Use Your Fresh Fruits or Red Wine

If your kitchen becomes infested with gnats because of fresh fruit sitting out, you can use that fruit to get rid of fruit flies. Rather than making a trap with apple cider vinegar, as described in the previous section, you can place bits of your overripe fruit in a small glass, bowl, or jar.  Cover the container with plastic wrap and poke small holes into the plastic with a toothpick.

You can also attract fruit flies with red wine and a couple drops of dish soap in a glass or jar. The dish soap separates from the wine, so whenever a gnat lands on the solution, it sinks and drowns.

Turn on Your Fan

Once you see a few gnats flying around your home, you could try adding more air flow to discourage them from sticking around. This is a great strategy to try before investing in traps or attempting other DIY methods, since it’s as simple as flipping a switch. Because gnats have small wings, they’re generally weak flyers and typically avoid windy environments or areas with a lot of air movement.

Clear Your Drains and Garbage Disposal

If you’re noticing gnats with fuzzy complexions and grayish colors, you probably have a drain fly infestation. Gnats and larvae usually nest in and feed on the moist, decomposing materials in your drain. The best way to eliminate these invaders is a deep cleanse of any sink drains that could be housing the drain flies. You can mix your own solution or purchase one to pour down the drain in your attempt to rinse out their home.

Here are some solutions to try:

Hire an Exterminator

If you try these methods and can’t fully eradicate your gnat problem, you may need to call a top professional pest control company to help, such as Terminix or Orkin. Their general pest control plans typically cover gnat infestations and can also help prevent invasions from a wide range of other pests, such as cockroaches, ants, and rodents.

A technician will come out to your property, inspect the gnats’ nesting areas, plus the rest of the interior and exterior of your property, and perform a comprehensive initial treatment for the gnats and other common household pests. Then, you can set up quarterly or bi-monthly scheduled treatments to continually prevent any issues in the future.

Tips for Preventing Gnats

Frequently Asked Questions

What causes your house to have gnats?

The cause of your gnat problem can vary depending on the type of gnat invading your home. Since fungus gnats typically live and breed in your indoor plants’ potted soil, too much moisture and organic matter in the soil is likely the cause. On the other hand, fruit flies are drawn to decaying fruits, so the bananas sitting on your counter or the bowl of apples on your table could be the cause of that issue. Drain flies are another common type of gnat in homes across the country, and they live and breed in the organic matter in your drain. If you haven’t cleaned your drains in a while and notice some fuzzy gnats that look like tiny moths, you likely have a drain fly issue.

Do gnats go away on their own?

No, it’s unlikely that gnats will go away on their own once they start reproducing. You will need to take proper measures to get rid of them, such as putting away your fruits, flushing out your drains, or changing the soil in your indoor plants’ pots.

Do house gnats bite?

No, most common house gnats don’t bite or cause any harm to your home. However, if you live near sitting water or in a generally moist environment, you may have issues with biting midges or no-see-ums on your property, gnats which can bite your skin and leave small, itchy bumps, similar to mosquito bites.

Where do gnats lay eggs?

Adult gnats usually lay eggs in organic material, depending on the species. For instance, while fungus gnats typically nest in decomposing matter in potted soil, fruit flies look for ripe or decaying fruits sitting out in open air to lay their eggs.

How We Chose the Top Pest Control Companies

Our pest control research process starts with analyzing customer reviews on third-party websites such as the Better Business Bureau (BBB), Trustpilot, and Google Reviews. We then do a deep dive into each company’s website, service plans, and available cost information. We also secret shop the companies we review, reach out to representatives, and request quotes.

From there, we compile the information we’ve gathered and compare each company using our in-depth pest control methodology and review criteria. This process uses a series of factors that are important to our readers, and we score each company depending on how well they perform in each factor. For instance, companies that offer more guarantees for their service earned more points than others, and pest control plans with a larger range of covered pests earned more points than ones with fewer.

After analyzing dozens of residential and commercial pest control businesses through this process, we were able to determine the best pest control companies on the market.
