What’s a gnat?

Gnats are teeny-tiny flying bugs which can be typically present in swarms and are recognized for his or her capability to hover in place. Three of the most typical varieties of gnats present in houses are fungus gnats, fruit flies and drain flies. You’ll first must rise up shut and private to establish which gnats you’re coping with in your house, with the intention to greatest perceive find out how to clear up the issue.

Varieties of Gnats

Fungus gnats are black with lengthy legs. They’re sometimes discovered close to potted crops.

Fruit flies

Fruit flies are brown with crimson eyes and normally extra spherical in form. They’re sometimes present in kitchens.

Drain flies

Drain flies are fuzzy with moth-like wings. They sometimes congregate round drains.

The excellent news is that whereas some species of gnats can chunk and sting, the categories mostly discovered indoors are merely only a nuisance to people, flying in your face throughout meal prep or throughout a cocktail party. “In a latest research, we discovered most of ‘flying bugs’ in houses are fungus gnats,” says Dr. Changlu Wang, who works within the Division of Entomology at Rutgers College, including that fungus gnats “don’t chunk folks or trigger allergic reactions.”

Whereas gnats are unlikely to go away on their very own, they are often managed with a little bit of vigilance and a few primary house treatments.

Learn how to stop gnats

Usually talking, gnats — together with many different pests — thrive in moist, humid environments, so chances are you’ll need to take into account working a dehumidifier in notably dank areas of your house. “In damp basements, preserve relative humidity beneath 50% and ensure bogs are properly ventilated,” says Dan DiClerico, the Good Housekeeping Institute’s Residence Enchancment and Outside Lab director. “Simply needless to say a dehumidifier received’t treatment the underlying supply of the humidity.” You’ll additionally need to repair any leaking pipes and ensure your house’s gutters and downspouts are channeling water away from basis partitions to maintain moisture out.

Past that, the best technique to stop infestations in your house by eliminating the bugs’ “meals” supply, which varies relying on the kind of gnat:

✔️ Fungus gnats are normally discovered close to houseplants. “Fungus gnat infestations are sometimes brought on by sources of damp soil, resembling houseplants, or decaying or broken plant roots,” says Dr. Jim Fredericks, a board-certified entomologist and senior vice chairman of public affairs on the Nationwide Pest Administration Affiliation (NPMA). To forestall fungus gnats, it’s necessary to usually repot your houseplants in new soil and ease up on overwatering them.

✔️ Fruit flies feast on decaying vegatables and fruits. To stop fruit flies in your house, rinse and dry your produce as quickly as you get it house from the shop, then preserve it inside bins or in your fridge as a lot as doable. “By washing them and storing them correctly, fruit flies can’t discover that meals supply anymore,” says Chelle Hartzer, an entomologist with Orkin. Fruits that ripen shortly — like apples, grapes, melons, pairs, peaches and plums — could be stored within the low-humidity crisper drawer; produce that’s liable to wilting, together with leafy greens, carrots and broccoli, belong within the high-humidity crisper drawer. Whereas bananas are greatest left on the countertop, ideally on a devoted banana hanger, you possibly can switch them to the fridge as soon as ripe, or peel and retailer them within the freezer in an hermetic container.

✔️ Drain flies are normally present in kitchen and loo drains, rubbish disposals and seldom-used bogs, since they like micro organism, sewage and gunk. To forestall drain flies, it’s necessary to clear and clear these plumbing strains regularly, particularly throughout scorching, humid summer season climate.

• To wash drains, pour in an answer of equal elements baking soda and vinegar, wait 5 minutes, then observe with boiling water. Cussed clogs may require a harsher therapy; Hartzer advises utilizing a drain cleaner like Drano Max Gel Clog Remover to flush out the pipes. If the problem persists, an ongoing infestation may indicate a leak, so call a plumber.
• To clean garbage disposals, toss a dozen ice cubes in the chamber, plus 1 tablespoon of baking soda, a few lemon slices and 1 teaspoon of bleach. Turn the disposal on without running water until you hear the grinding stop. Then, with the motor running, flush with cold water for 30 seconds.

How to get rid of gnats quickly

While preventive measures will stop gnats at the source, sometimes it’s best to take immediate action. Here are the most effective ways to get rid of gnats, instantly.

1. Use a high-tech bug zapper.

We’ve found that plug-in traps can be extremely effective. Consider the Zevo Flying Insect Trap, a GH Seal holder that uses safe amounts of blue and UV light to attract gnats, fruit flies and mosquitoes. “I personally love the Zevo traps that have earned our Seal; I have them in my house all year round,” says Birnur Aral, Ph.D., director of the Good Housekeeping Institute’s Health, Beauty and Sustainability Lab. “We recently tested the latest version of the product and found it be even more effective at trapping gnats.”

In our tests, the Zevo Flying Insect Trap started trapping insects right away and was filled with dead ones when it was time to replace the cartridge after 15 days.

2. Try a spray solution.

The Zevo Fly, Gnat & Fruit Fly Flying Insect Spray, another GH Seal holder, is also a good option. It uses geraniol and lemongrass oil, which are bio-insecticides that don’t need to be registered with the EPA, to kill gnats on contact. Though safe around people and pets, the spray must be handled properly; Zevo cautions against it coming into contact with eyes or skin, and the flammable liquid should never be used near electrical wiring.

3. Make a DIY vinegar trap.

One of the best and easiest methods is to set up a vinegar trap. There are a few ways to do this:

• Make a trap with apple cider vinegar and plastic wrap: DIY your own fruit fly trap by pouring a little apple cider vinegar into a glass or just removing the cap from the bottle. Cover the opening with plastic wrap and secure with a rubber band. Then, poke a few small holes in the plastic. The fruit flies will enter but not be able to make their way out.
• Make a trap with a paper cone, vinegar and old fruit: Place a little vinegar and a chunk of very ripe fruit in a jar. Then, roll printer paper into a cone and stick it into the jar, placing the narrow opening down. The smell of rotting produce will help entice the fruit flies into the mixture, but the paper cone will make it difficult for them to escape.
• Leave out a bowl of vinegar and dish soap: Add three drops of dish soap to a bowl of vinegar, and leave it uncovered in problem areas. The soap cuts the surface tension of the vinegar, so the flies that are enticed by the vinegar will sink and drown.

4. Put out a beer or wine trap.

Along with vinegar, fruit flies also like the smell of wine. Leave out an almost-empty open bottle of old wine — the skinny neck will keep the flies trapped. The Old Farmer’s Almanac also recommends using stale beer to attract fruit flies.

5. Buy a sticky trap.

For a fail-safe trap, buy Aunt Fannie’s FlyPunch! on Amazon. The mixture includes sodium lauryl sulfate (a surfactant used in soaps) and malic acid (found in fruit). Just open the top, set it on your counter and watch the cycle of life unfold.
