Gnats are primarily attracted to sweet and fruity scents, but many species of gnats are also drawn to water and body heat. Perspiration and even the moisture of your eyes and nose can draw in gnats. Fruits, vegetables and flowers growing in your garden or food residue in your sink can attract these pests.
Most varieties of gnats are attracted to the combination of moisture and heat. They're particularly attracted to overwatered gardens and water features like ponds or fountains.
Use a small saucer to mix a few tablespoons of apple cider vinegar, a few drops of dishwashing soap and a little sugar. Put the saucer near the gnats. Use more than one saucer, if needed. The gnats will be drawn to the sweet solution, fall in and get trapped.
Fungus gnats are small flies that infest soil, potting mix, other container media, and other sources of organic decomposition. Their larvae primarily feed on fungi and organic matter in soil, but also chew roots and can be a problem in greenhouses, nurseries, potted plants and interior plantscapes.
Gnats have been known to eat algae, decaying plant matter, fungi, nectar, and plant roots. For some species, the female requires a blood meal in order to lay eggs.

Wear clothing like long-sleeved shirts and pants to protect your skin in areas where gnats thrive. Stay inside during dawn and dusk when these biting gnats are most active.
Additionally, houseplants can harbor gnats, particularly fungus gnats, which lay their eggs in moist soil. The larvae then feed on organic matter in the soil, potentially harming plants and causing an infestation. Overwatering plants only makes this situation worse.
In addition, gnats may also be attracted to certain scents, such as perfumes or lotions, which can increase the likelihood of being bitten. Other factors that can make individuals more susceptible to gnat bites include sweat, body odor, and certain blood types. Not all species of gnats bite humans or animals.
Gnats are seasonal pests that thrive during the spring. With proper methods of control, they may eventually go away as the year progresses. Gnats have a short life cycle and will often disappear when the cold months start.
The only way to get rid of gnats without killing them is to repel them with scents they don't like: vinegar, vanilla, pine oil, peppermint, lemon, eucalyptus, and lavender. Even dryer sheets could help. Of course, the first line of duty would be to get rid of the infestation's root cause.
Fungus gnat adults may live from about one to two weeks and complete one life cycle in about 18-30 days. Moth fly adults live for about 14 days and complete their life cycle in about 7-21 days.
Chamomile Tea & Cinnamon
Chamomile and cinnamon are powerful natural fungicides, which kill off the gnats' primary food source, therefore making the soil inhospitable.
Place a bowl near the infestation and fill it with vinegar before adding a teaspoon of plain sugar, which is what the gnats will be drawn to. The vinegar is what will ultimately kill them, but you also need a way to keep them in the bowl long enough for that to happen.
In general, gnats go through the four life stages of egg, larva, pupa and adult, similar to other flies. The fungus gnats lay their eggs in moist organic debris or soil, which hatch into larvae. The larvae feed on organic matter such as leaf mold, mulch, compost, grass clippings, root hairs and fungi.
Breath, Sweat & Tears
A gnat is always searching for moisture and salt, which are found in sweat and tears. Unfortunately, the pests are vectors for pink eye. They are also drawn to the smell of bad breath and to the carbon dioxide people expel when exhaling.
You can prevent insect bites by wearing protective clothing, using insect repellants, and avoiding being outdoors during early morning or dusk when gnats are most active.
Homemade gnat repellent spray: A mixture of dish soap, water, baking soda, and vinegar can be filled into a spray bottle. The mixture should contain a few drops of dish soap, a tablespoon of vinegar, and baking soda per cup of water. A few sprays of this mixture is an effective gnat repellent.
While it's very unusual for someone to have an allergic reaction to a gnat bite, you should tell an adult right away if you feel sick, have a hard time breathing, or get hives (red patches on the skin that sting and itch). The doctor can treat allergic reactions with medicines.
Bugs are naturally attracted to bright colors like white, yellow or orange. Colors like green and blue won't register as vividly when seen in the UV spectrum, deterring bugs away from these colored objects.
“These pests are attracted to moisture, so you may see swarms in areas with damp soils, standing water, or even houseplants that have been overwatered,” Ludwiczak adds. “The breeding habits of gnats are most active during warmer months, which is why they seem to be especially prevalent during summer.”
You can use nearly any type of cooking oil to keep gnats away. Choose olive oil, coconut oil, or vegetable oil for instance. Then, soak a cotton ball in the oil, and dab it over your forehead, behind your ears, and down your neck. The oil masks your scent from the gnats so they are less likely to notice you.
Gnats have a strong aversion to various smells, including peppermint, lemon, eucalyptus, vanilla, lavender, citronella, and DEET, so you can use this characteristic to ward off gnats.
Gnats are active mostly during the day, especially around mid-morning and dusk. Biting usually peaks during a three-week period in late spring or early summer, and is usually more severe following droughts.
While gnats may momentarily land on or fly around your hair, they do not typically take up residence or establish nests in human hair like some other pests. However, gnats can be a nuisance when they fly near your face or hair, especially in outdoor settings.
