Even if you are implementing a good tactic to keep insects away, you will still have to deal with a gnat problem whether it is in your kitchen, dining room, garage or working area.
Here are the best solutions to eliminate gnats and houseflies from your premises.
1. Apple Cider Vinegar Trap
Many insects, including gnats and house flies, are attracted to the scent of apple cider vinegar. It is one of the recommended solutions on how to get rid of gnats in the house quickly due to its efficiency.
To make a trap, you will need a small jar or bowl with a lid, apple cider vinegar, and dish soap. You can also try to use white vinegar if apple cider is not available.

- Add 5 to 8 drops of dish soap (preferably lemon-scented) and mix it well.
- Cover the jar or bowl with a plastic wrap.
- Create small holes using a toothpick or fork, enough to allow the flies to enter the container.
Once you are done, place the apple cider vinegar trap where the gnats are swarming. These insects will get attracted by the smell and will try to enter through the holes.
As they touch the surface of the solution, they won’t be able to escape due to soap. When the container fills up, dispose of and refill it.

Gnats usually lay their eggs in damp, over-watered soil as larvae require moist organic material to develop. Finding and destroying the breeding source of gnats can reduce their number efficiently.
- If overwatered soil in a pot is the source, refrain from watering until it becomes dry. Allow the top two inches to dry completely before watering the plant again.
- Another option is to cover the gnat-ridden soil with a 2-inch layer of coarse sand.
- If the source is outside, disinfect the area with Clorox and water. Sprinkle some borax to kill and prevent the insects from coming back.
- Do not over-water houseplants to prevent gnats from laying their eggs in the soil.
To check whether your potted plants need to be watered, place a finger in the soil up to your first knuckle. If the soil at the bottom is still wet, there is no need to water your plant.
7. DEET Insect Repellents
DEET repellents available in the market are the most effective when it comes to eliminating different types of insects. However, this may cause health problems if used in high concentrations.
It is important to use products that contain DEET with caution.

What Attracts Gnats?
It doesn’t matter what kind of gnat is flying around your face, the fact of the matter is, they are annoying flying insects. What are gnats? Many of these tiny flying insects are thought of as “gnats” even though many of them are actually small flies.
Fungus gnats, drain flies, and buffalo gnats fit the profile. The common flies that are usually referred to as gnats are phorid flies, sand flies, and the ever annoying fruit flies. Regardless of the name you give them, these annoying little black flies always seem to show up when you least expect them and just a few of these pesky insects can quickly turn into a gnat infestation.
You may be wondering how you ended up with a gnat problem in the first place. Let’s look at what attracts gnats and find out how to eliminate flies for good.
Why are Gnats Attracted to Me?
What are gnats and why do they like me? If you have a gnat problem inside or outside your home, many things could be bringing them to your house. The majority of gnats and small flies are attracted to scents, especially the smell of fruit and other sweet fragrances, which is why you might find gnats hanging around your flower beds.
If you use personal hygiene items, like soaps, perfumes, lotions, and hair sprays that have a sweet scent, this could be one reason why adult gnats tend to swarm you. The smell of your laundry detergent or other additives on your clothes will also bring them toward you. Gnats are also attracted to carbon dioxide, which is why these light brown flies tend to hover around your mouth.
Your body heat and moisture also play a significant role in attracting gnats to you. Many of the gnat species and small flies are drawn to body heat, while others are looking for moisture.
Where do gnats come from? Along with being drawn to sweat, some of these tiny flies are drawn to the mucus around your eyes and nose, which can be a source of moisture for the pests.
Gnats are Attracted to:
- Organic matter
Why are Gnats Attracted to My Yard?
If you have gnats in your yard, several things could be attracting them. Fruit trees, flowers, and vegetable gardens all provide a food source and breeding sites in which gnats thrive, as well as other organic material in your yard.
If you overwater your plants and lawn, the moist soil not only provides gnats with the moisture they need to thrive, but it can also create molds and fungus where gnat larvae feed. Spray some hydrogen peroxide to eradicate fungus gnats on the soil of your houseplants and those in the yard.
Why Do I Have Gnats in My House?
Many of the same items that attract flies and gnats outside your home are also found inside your home. Overripe fruit and vegetables, the moist soil in your potted plants, decaying organic matter in your garbage cans and sink drain, are all things that will bring gnats into your home. Bringing in fresh flowers and indoor plants also appeal to these pesky flying insects.
Fungus gnats will live and reproduce in the soil of your houseplants and feed on the plant roots. Even with their short lifecycle of several weeks, they can quickly reproduce, leaving you with a substantial gnat problem.
Are Gnats Attracted to Light?
When it comes to the non-biting gnats, like fungus gnats, fruit flies, moth flies, and phorid flies, their attraction to light varies. Adult fungus gnats are strongly attracted to light, which can be used to assist in gnat control, both inside and out.
Indoors, fungus gnats can often be found flying around windows, interior lighting, TVs, and doors, while outside they are often found swarming outdoor lighting.
If you’re wondering are fruit flies attracted to light? The answer is no. Phorid flies aren’t strongly attracted to light either and male moth flies, are attracted to light, but female moth flies are not.
Does Vinegar Attract Gnats?
Vinegar is almost irresistible to gnats and can make an effective gnat trap. You can kill fungus gnats and fend off house flies with vinegar and get rid of these pests for good. This simple gnat trap uses household items to kill gnats and is an effective pest control method.
The smell of the apple cider vinegar in this fly trap attracts the tiny flying insects into the fruit fly trap, but they can’t escape, leaving them to drown. Eliminate flies and gnats with this simple recipe.
DIY Vinegar Trap
- ¼ cup apple cider vinegar
- 3-5 drops dish soap
- Small container
- Plastic wrap
Pour the vinegar into the small container. Add several drops of dish soap. Cover the opening of the bowl with plastic wrap and pierce the surface of the Saran wrap to create several small holes.
Place the fruit fly trap in areas where you have a gnat problem. After a couple of days, dump the vinegar solution with the dead gnats and refill the nat trap with fresh vinegar. If you don’t have any cider vinegar on hand, you can substitute it with red wine.
What are the Best Natural Gnat Repellents to Use?
The best natural gnat repellents will contain botanical oils like citronella, cedarwood, garlic, lemongrass, spearmint, cinnamon or lemon mint. You use any of these essential oils diluted with water to spray the areas in your home where gnats are congregating.
If you want to keep gnats away from your outdoor living area, consider planting pennyroyal or lavender near places where you and your guests tend to gather. You can also crush the fresh leaves of these plants and rub the leaves over your skin to deter those gnats that bite.
Gnats are extremely annoying little pests, but if you know what attracts them, you can make the necessary changes to your yard and home to keep them from invading.
