How To Get Rid Of Fruit Flies On Outdoor Plants

1 cup of warm water and 1/2 a teaspoon of dishwashing liquid should be combined. Spray the liquid on the fruit flies on the plants after putting it in a spray bottle. To remove the flies from the plants, use a gentle cloth.

Where can I find fly repellent for my outdoor potted plants? advises that the greatest way to protect plants from flies when managing flies in potted plants is through prevention.

However, there are a few ways to deal with the infestation using both chemical and natural approaches if you already struggle with fungus gnats.

Control Fungus Gnats Naturally

When it comes to getting rid of fungus gnats from your plants, natural methods are amazing. There are numerous alternatives. More frequently than not, natural approaches to fly control are more effective than chemical insecticides.

Clean the Roots

Eliminating the larvae of fungus gnats is one of the simplest ways to stop them. To remove the soil from your plant, simply take it out of the pot.

Use water to wash the roots. Be kind! Try your best to remove all of the eggs and larvae that are clinging to the plant’s roots.

After disposing of the contaminated dirt, wash the pot with soap and water. Put new dirt in a new pot for your plant. After a few weeks, check on the plant to determine if it still requires cleaning.

Dry Out the Soil

When your plant goes into dormancy in the winter, this strategy works well.

The larvae of fungus gnats require moist soil to live. Give the soil a few days to dry out. Any larvae within the pot will die due to the lack of moisture, and fungus gnats won’t find your potted plant to be the ideal place to nest.

Insecticidal Spray

Make an effective insecticidal spray to put on the plant’s roots if your plants are still having issues with fungus gnats.

To a gallon of water, add two tablespoons of mild soap (such as Dawn dish soap or Castile soap). To spray the soil and plants, pour the solution into a spray bottle.

Why do I have fruit flies in my garden?

  • Fruit flies in the garden are a warning that it’s time to compost any decaying waste.
  • Plant blooming groundcovers between trees if you have fruit trees and live in a temperate zone to draw ground beetles, who prey on flies. In the summer, pick up and dispose of any fallen fruit every day.
  • Fruit that is ripening indoors should be eaten right away or put in the fridge. Empty your indoor compost bin on a daily or two-day basis while keeping it well covered.
  • If you discover fruit flies within your home, start by searching for and removing any rotting produce. Don’t forget to clear out your garbage disposal and look through cabinets for potatoes or onions that are starting to rot. Usually, the issue will go away within a few days.
  • A fruit fly trap should be set up, or a sweet attractant like cider vinegar should be placed inside a bottle or other container that fruit flies can enter but cannot fly out of.

Why are my outdoor plants covered in flies?

Depending on the species of fly, they are drawn to flowers for various reasons, but frequent ones include moist soil, a lot of organic matter on top of the soil, and decomposing plant matter.

Why do my plants have small flies in them?

1. Modify your drinking habits

Pests like fruit flies and gnats thrive in moist soil; their eggs and larvae cannot survive without a steady supply of moisture. Your plant probably needs less water than you are giving it, so try checking the soil with your finger and only watering when the top 2 inches of soil are completely dry. If you struggle to accurately measure moisture on your own, you can get a moisture sensor gauge that you can simply insert inside your planter. Keep in mind that the main reason why houseplants die is overwatering!


If your planter has a tray underneath, make sure to drain it right away after watering to prevent moisture buildup. The perforated holes at the front of the Wally Eco Wall Planter’s basket allow the soil breathe and remove extra moisture, but be careful not to overwater. If the air in the bathroom is excessively humid, move your plant outside or turn the humidifier down a notch.

Use sticky traps

The adult fungus gnats are caught in yellow sticky traps, which disrupts their life cycle. Simply affix a trap to a bamboo cane that has been placed into the compost near the affected plants. Because gnats rarely fly far from the compost, keep the trap close to the ground. The traps should not be hung outside as they will also catch butterflies and hoverflies.

Why do fruit flies die quickly?

Throwing away anything on your kitchen counter is the first step in getting rid of fruit flies because they may have placed their eggs on ripe or rotten food. Do you really want to eat that apple? Fruit fly larvae tunnel into produce to feed, so it may seem wasteful. Any fresh produce you bring home should be washed thoroughly and kept in the refrigerator until the bugs are defeated.

You might want to take the garbage out more frequently since fruit flies might breed in your trash can, especially if it contains rotting food. Additionally, you should flush your garbage disposal. To remove any food that is stuck on, grind a few ice cubes, then rinse with hot water. Keep your kitchen as clean as you can for at least a week to stop female fruit flies from laying new eggs. Regularly wipe down counters to make sure the flies don’t discover any food leftovers.

Fruit flies can be prevented from reproducing by cleaning your kitchen, but you’ll probably also want to get rid of the insects that are buzzing around your house. (You could just wait for them to disappear, but under the correct circumstances, they can survive for up to two weeks.) The best method to accomplish this is with a homemade fruit fly trap that you can create from supplies already in your cupboard.

Add a few drops of dish soap to a small bowl of apple cider vinegar (ACV). Because it smells like fermenting fruit, apple cider vinegar repels fruit flies better than white vinegar. Red wine vinegar will also function but is typically more expensive than apple cider vinegar. To make the vinegar smell stronger, microwave the mixture for about 20 seconds. After that, put the bowl somewhere where there are lots of flies. The aroma will entice the insects, and because the dish soap lowers the liquid’s surface tension, they will become trapped and drown. In a few of hours, you’ll start to see progress. When the solution begins to get saturated with dead flies, dump it and refill it.

Trapping the flies in a bottle of leftover beer, fruit juice, or wine is another common do-it-yourself solution that works brilliantly. Put a rubber band and plastic wrap over the bottle’s opening, then pierce several tiny holes in the top. The flies will go inside after being drawn by the pleasant aroma of fermenting grapes, become stuck, and eventually perish.

You can purchase fruit fly traps online or from home improvement stores if you don’t want to use a vinegar trap or another do-it-yourself alternative. For instance, the TERRO Fruit Fly Trap comes with a liquid that you pour into the apple-shaped trap; the aroma attracts the insects, who eventually drown as a result of the liquid’s scent. Flypunch is a comparable choice. You simply open the lid of the container, which resembles a spice jar, and set it next to the bugs.

Do fruit flies harm plants?

Fruit flies are an inconvenience, but it’s comforting to know that they are simple to eradicate in plants.

Fruit flies can be found year-round, but the University of Kentucky reports that they are most prevalent in the late summer and early fall because they are drawn to ripened and fermented fruits and vegetables.

How can a fruit fly infestation be stopped?

They seem to appear out of nowhere, are tiny, and are a nuisance. Fruit flies, which are in their peak season during the summer and may be a major annoyance, will disappear when the crisp early October air arrives.

Fruit flies are so small (1/8″) that they may squeeze through the smallest cracks in doors or windows or even fly right through window screens to enter your home. In fact, you might be bringing them into your house by yourself.

How’s that? Unbeknownst to you, fruits or vegetables you bring inside from the grocery store, farmer’s market, or your own garden may contain fruit flies. Fruit begins to ferment as it becomes overripe or begins to go rotten, producing alcohol that draws fruit flies. They are able to lay hundreds of eggs, which develop into larvae in just a few hours, as they consume the fermenting fruit. Additionally, fruit flies have an almost continual breeding cycle due to their notoriously short life cycles, which last around a week from egg to adult.

Fruit Fly Infestation: How to Prevent and Treat

Here are some steps you may do to keep fruit flies out of your house:

  • Keeping fruit and vegetables in the refrigerator will delay the ripening process.
  • Fruit kept on countertops needs to be thoroughly cleaned and covered.
  • Kitchen garbage cans should be emptied frequently, especially if they contain food.
  • Keep your sinks and garbage disposal clean.
  • To manage a minor fly invasion, use a fruit fly trap. The TERRO fruit fly trap draws flies to the trap using a bait made of apple cider vinegar. The trap, which is positioned close to ideal nesting locations, captures adult fruit flies and breaks the breeding cycle. Another benefit is that the adorable apple pattern looks great in any kitchen. It’s the most alluring fruit fly defense strategy there is!

What plants outside entice flies?

Daisies, fennel, and sunflower plants are also known to draw flies. In addition to the Euonymus family as a whole, flies prefer certain plants more than others. Some of these plant species are attractive and modest, so it may surprise you to learn that they seem to be the worst fly magnets.


The perennially well-liked sunflower, or Helianthus annuus, comes in first place on our list. One of the main kinds that draw flies because of their petals and foliage are these happy-looking flowers that enjoy soaking up the sun.

Along with flies, it also draws pests like hoverflies that feed on pollen and nectar, predatory wasps, and others. Aphids are also known to enjoy congregating near sunflowers.


It has been demonstrated that this member of the carrot family attracts a sizable number of flies, especially during the blooming season. In contrast to shrubs and tall plants, fennel is small and close to the ground, making it a favorite for flies.


Sunflowers and daisies are both outdoor plants that draw flies and other insects. This is due to the fact that daisies, with the exception of the fact that they are normally smaller flowering plants, are quite similar to sunflowers and various aster species.


The dill has a quality that makes flies and other insects crazy. Even the general consensus is that if you have a dill plant, flies will arrive soon after. It is not unexpected that insects are drawn to this fragrant plant given how common it is as a herb.

Gnats in potted soil: how can I get rid of them?

Fortunately, there are several of organic and chemical-free ways to get rid of fungus gnats from your prized plants. You can use a traditional trap or common household goods like potatoes and dish soap!

Let the Soil Dry

It’s important to remember to let the soil dry out for a few days and refrain from watering your plant because fungus gnats and their larvae prefer to nest in moist soil. The gnats will be forced to live in an uninhabitable habitat as a result, and they will disappear in dry soil. Do not be afraid to skip your next watering in order to get rid of the gnats; your houseplant will be able to endure the dryness for a longer period of time than you might imagine.

The best advice is to take your plant out of the planter and drain any extra water from the bottom. Thus, there won’t be any dampness where gnats might deposit their eggs.

Use Traps

There are numerous traps you may employ to get rid of these bothersome bugs if you’re seeking for a speedier fix. You can choose to DIY these with a few common things or run to the store and buy specialist traps, depending on what best suits your needs.

  • Pour a cup of white vinegar and a few drops of liquid dish soap onto a shallow saucer. The gnats will be drawn to the solution and fall into the trap if you place the bowl near your plant. Repeat the procedure until no more gnats are present.
  • Sticky fly traps are an alternative if the smell of vinegar deters you from making your own homemade gnat trap. These little yellow paper sheets attract gnats and trap them with glue because of their brilliant hue. Although it might not be visually appealing, this procedure is simple and safe.
  • Consider purchasing an indoor fly-catching gadget if you’re sick and tired of gnats in your plants and need an urgent fix. These are typically USB-powered and can be purchased locally or online. The blowers and LED lights draw the gnats, and eventually they are drawn into the trap.
  • Are there any extra potatoes in the kitchen? Set a trap for them! Place the potatoes flesh-down on the ground after cutting them into little pieces. The fungus gnats will be drawn to the potatoes by their dampness. Just be careful that the parts don’t dry out otherwise it won’t operate.

Sanitize and Repot

Consider removing the plant from its planter and scraping out the soil if you want to take matters into your own hands. When doing this, take care not to disrupt the roots and take only what you can get rid of. Put the contaminated soil in a plastic bag and wash the planter with soap and warm water to sterilize it. Repot your plant into new soil after this is finished, then put it back into its planter.

Use a Spray Bottle

Take a spray bottle and combine water and dish soap in it. Repeat the technique until all of the gnats are gone by spraying the solution on the top layer of soil. If you’re seeking for a quick and natural solution to get rid of fungus gnats, try this.
