Will Vinegar Kill Fungus Gnats?

She asked me to write about a true issue she was having with her indoor plants. Of course! I bet many of you are struggling with the same issue.

Have you ever purchased houseplants for your home or office with the intention of bringing some nature indoors but noticed after a week or so that obtrusive small black flies are darting in and out of your line of sight with your computer screen? Ugh! You have a problem with fungus gnats!

Although fungus gnats resemble tiny mosquitoes or fruit flies, they are unrelated and do not bite. They can be spread by cut flowers, especially those with stale vase water, or even by plants with unsterilized soil (poinsettias can be the worst).

In moist plant soil, residential drains, and sewage areas, fungus gnats can be found. In wet soil, fungus gnats lay their eggs. Prior to developing into adult gnats and flying out of the plant soil onto your face, their larvae, which are only one-hundredth of an inch long, are almost impossible to notice. They eat plant roots, soil-borne leaves, and decomposing plant matter. It takes them around 10 days to grow. Indoors, they can reproduce all year long.

This issue is being exacerbated by the gentle care you provide your indoor plants, including watering them. The fungus gnats will like staying in your home if the soil of your houseplants is continually moist. The growing medium used for houseplants is another factor. Numerous potting mixture types contain components that hold onto moisture, and everything that promotes moisture also promotes fungus gnats. To avoid potential pests, Good Earth Plant Company only purchases from nurseries that pre-treat the soil.

So what can you do to combat these annoying little gnats? You must approach the issue from many angles.

Start by starting to wait longer between waterings for your indoor plants. One to two inches of the surface ought to be entirely dry. Sub-irrigation functions well for this reason, among others.

2. Make careful to get rid of any fallen or decomposing plant materials (leaves and roots) as these serve as fungus gnat larvae’s feeding sources. Place a few slices of uncooked potatoes on the surface of the soil to see if you have them. Take a look at the bottom after a few days. Are they chewed-looking? Your plants contain fungus gnat larvae.

3. You can cover the soil with a quarter- to-half-inch layer of diatomaceous earth or horticultural sand (NOT playground sand) to control the larvae. If you water it, the plant will dry out more quickly and fool the fungus gnats into thinking it is not a good site to lay eggs. Additionally, they are actually cut to death if they crawl across the DE.

4. Add one tablespoon of liquid dish soap and one teaspoon of white vinegar to the water every other time you water. The fungus gnat larvae will eventually perish as a result.

5. You can remove the plant from the pot, remove as much soil as you can without harming the plant, and then repot it to expedite the process. Place all of the used soil in a sealed bag and discard it. It cannot be applied elsewhere because doing so will just exacerbate the issue.

6. You can create organic traps on your own to get rid of the adult fungus gnats. You can pour a few drops of liquid dish soap to the bottom of a deep bowl after adding apple cider vinegar or red wine. Put it next to the infected indoor plants. The gnats adore it and will suffocate in it if they fall in. Every couple of days, replace it.

7. You can either buy or manufacture some sticky insect traps. Use cardboard pieces that are a vibrant yellow color, and cover them with Vaseline. For optimal effects, place them horizontally over your plants. Use a card holder from your florist, or one that comes with a plant. Put the card holder with the sticky trap inside, then affix it to your plant.

8. Some backyard gardeners fervently advocate adding three percent hydrogen peroxide directly to the soil of your plants. I wouldn’t advise this as your first option if you have a plant that is very priceless or sensitive.

It could be extremely difficult to entirely eradicate fungus gnats on your own if they frequently infest your plants, especially those in your office. In one instance, the gnats were entering through the ventilation system from another office, as I’ve seen!

We only utilize plants from reputable growers, and our experts take great care to prevent conditions from becoming such that fungus gnats can easily reproduce. We quickly remove any infected plants from our care (which doesn’t happen very often) to prevent fungus gnats from spreading to the rest of your plants.

Can I use vinegar to spritz on my plants to get rid of gnats?

Fill a spray container with one cup of water, one tablespoon of apple cider vinegar, and a few drops of dish detergent to create your own homemade gnat spray. Gnats can be killed with this spray anywhere you find them, including on your indoor plants.

If everything else fails, try these simple gnat sticks, which are available to buy on Amazon. These gnat sticks have been used successfully by many individuals to capture and eliminate gnats on their indoor plants.

What rapidly eradicates fungus gnats?

1) Get Rid of Extra Moisture

This should be done as soon as a fungus gnat problem is detected. Dry out the soil on the plant’s top few inches. By doing this, you can discourage adult flies from depositing eggs in the soil and stop them from reproducing. If you’re lucky, a lot of the eggs and larvae may also be killed by this. Moreover, get rid of any standing water. This covers the pot drainage tray as well as adjacent sources like leaky pipes, condensate puddles, and other similar situations.

2) Grip-Straps

Light attracts fungus gnats, as does the color yellow. To catch adult flies, place yellow sticky traps close to, hanging from, or inside the potted plant. Specially made for potted plants are these adhesive traps on stakes! These bigger ones are also hung in our greenhouse to trap gnats and other flying pests.

Sticky traps will initially ease some of the problem, but keep in mind that fungus gnats spend the majority of their lifetime as eggs and larvae. The cycle will carry on if the adult flies have already laid further eggs. However, using sticky traps to catch fewer adult flies can help reduce the overall problem. For several weeks, keep using sticky traps to completely end the cycle and get rid of fungus gnats.

3) Employ hydrogen peroxide to eliminate fungus gnats

If drying out the soil and placing a few sticky traps is ineffective, there are a number of natural and non-toxic treatments that can be used to eradicate fungus gnats. Utilizing hydrogen peroxide, which you most likely already have lying around your home, is one alternative. the positive news It is easily accessible, simple to apply, and won’t hurt your indoor plants. The good news? Apparently, fungus gnat eggs, larvae, pupae, and adult flies are all instantly killed by hydrogen peroxide. Suckers, goodbye.

Make sure to use regular 3% household hydrogen peroxide and not the industrial-strength material when making a hydrogen peroxide solution. Mix it with 3% hydrogen peroxide and water to dilute it slightly (e.g. 1 cup peroxide and 4 cups water).

Before application, allow the soil to somewhat dry out. The soil should then be vigorously sprayed until it is saturated down a few inches. Alternately, water the entire plant while letting it soak up all the dirt for a more thorough and effective treatment. It will bubble and foam, and that’s completely natural. It swiftly decomposes into water and oxygen molecules, neither of which pose a threat to plants.

4) Bacillus Thuringiensis for Fungus Gnat Biological Control

Utilizing biological controls like Bacillus Thuringiensis is another non-toxic method of treating fungus gnats. Specifically, the Bti subspecies of israelensis. A naturally occurring bacterium called Bti is discovered in soil. The EPA claims that Bti contains spores that create poisons that solely affect, target, and affect the larvae of blackflies, fungus gnats, and mosquitoes. It is not detrimental to other organisms, in other words.

There are a few different kinds of Bt, despite the fact that you may have heard us mention it previously. As opposed to this Bt product (Bacillus thuringiensis kurstaki), which targets caterpillars like cabbage loopers and moth worms but is ineffective against fungus gnats, Bti is effective against fungus gnats.

Follow the directions for a “soil drench” on the Bti product you buy to apply it. Since merely spraying the surface of the soil may not penetrate deeply enough to kill all of the fungus gnat larvae, it is typically advised to water the plant with the solution. Repeat as necessary while according to the directions. This Gnatrol brand is one well-liked alternative. Get it? Organic gnat control

5) Soil Drenching with Neem Oil

A neem oil drench can also be used to kill fungus gnats in the affected soil, much as hydrogen peroxide or Bti. Use neem oil, but not pure, concentrated neem oil! By adhering to the manufacturer’s recommendations on the neem oil product you choose, you can make and apply a diluted neem oil solution. Fungus gnats can be killed and deterred by watering with a diluted neem oil solution.

When looking for neem oil, I generally advise avoiding pre-mixed goods that include a lot of extra ingredients and instead opting for a high quality cold-pressed pure neem oil. Neem oil must first be emulsified because oil and water don’t mix well. This is necessary for an even and effective application of neem oil. Visit our post to learn how to mix and apply neem oil correctly for your garden or indoor plants.

Are fungus gnats repelled by vinegar?

Yes, vinegar will successfully get rid of fungus gnats. You can set up a trap to entice them away from your plants and get rid of them as pests after creating a vinegar solution.

How much vinegar is required to get rid of gnats?

Have any gnats been around your fruit bowl? Here’s an effective method to get rid of them. You’ll need dish soap, water, sugar, apple cider vinegar, and a container to make it work. Simply combine one liter of water and about two tablespoons of vinegar. Set the container close to the fruit, add a spoonful of sugar and a few drops of dish soap, and whisk everything together. The aroma will draw the insects, and when they come into contact with the solution, they will become trapped in the soap and drown.

How can I use vinegar to get rid of gnats in my potted plants?

Instead of discarding the plant, you can use home vinegar to get rid of bothersome fungus gnats.

  • An efficient fungus gnat trap can be made by adding one-quarter to one-half inch of apple cider vinegar to a clear or semi-transparent plastic cup.
  • Check the vinegar trap every day and place it close to your houseplant.

How do gnats get rid of dryer sheets?

How to Get Rid of Gnats Using Bounce Dryer Sheets

  • Take a Bounce dryer sheet out of the packaging.
  • To keep gnats off of you, vigorously rub the dryer sheet over your clothing.
  • The dryer sheet should be tucked into your pocket.
  • Dryer sheets can be cut into strips and taped to the sides of plant pots with organic matter-rich soil.

Do fungus gnats naturally disappear?

Gnats are annoying because they dare you to capture them as they dart around silently and frequently within a few inches of your face. The fungus gnat, however, can be the most annoying insect of all if you love plants. Fungus gnats can grow quickly in indoor plants and lay their larvae in the potting mix’s top layer, even though they are safe to people. During the winter, these bothersome gnats might be transported within from outside plants. But more often than not, they come into your house on sick plants you brought home from the nursery or garden center. They enjoy hiding in extremely soggy soil that is rich in decomposing plant materials. Once established in one plant, they simply move on to other ones close by, where their larvae contentedly await birth in the first inch or two of soil. The main source of nutrition for larvae is fungi found in the soil, but they can also consume root hairs. The infestation keeps expanding as a result of the adults producing eggs and proliferating. But don’t worry; you won’t have to throw out any of your plants to get rid of fungus gnats. Allowing the soil of afflicted plants to totally dry out will kill the larvae if the infestation is new. However, if the infestation is getting worse, you’ll need to take more drastic measures. Sticky paper might be used to catch the adult fungus gnats, but the larvae that are laying eggs won’t be destroyed. I’ve discovered a simple, secure two-step home fix (sidebar, right) that completely solves the issue. Sand, many tiny saucers, and a delicious, fruity beverage—for the bugs, not you—are all that are required.

Steps to gnat-free

First, construct the sand trap. Get rid of the already-hatched larvae by gathering all affected houseplants and removing the top 2 inches of potting soil. The dirt should be thrown away right away, and its top layer should be replaced with sand instead, which dries up rapidly, is organic-free, and is not a good spot for fungus-gnat eggs to hatch. Before the following watering, allow the soil below to totally dry out. This should destroy all fungus-gnat larvae present and stop the laying of fresh eggs.

Set up the open bar in step two. It is simple to entice and drown adult fungus gnats using any sweet liquid that has a decaying odor. One of the most effective and affordable fungus-gnat lures I’ve discovered is a lovely $2 bottle of alcohol-free wine from Trader Joe’s. Place a tiny saucer with the liquid in it next to a previously affected plant (or by all infected plants if the infestation is already rampant). You should wake up to a disconcertingly pleasant collection of dead fungus gnats floating in the liquid if you let it sit overnight. The saucers should be discarded and refilled until no adult gnats are seen.
