How To Keep Gnats Away From Plants?

We’ve all seen those pictures of gnat-infested plants, but have you ever thought about how to get rid of them? It can be tough to remove gnats from your plants if you don’t know how to get rid of them. 

We all know that gnats are annoying, but it can be pretty frustrating if they keep coming back in the houseplants you care about—the gnats like moist soil and potted plants. You will know you have them when you see tiny, grayish, or black flies flying around your plants. The gnats can be found in the top 2 to 3 inches of the soil, feeding on plant roots, fungi, and decaying matter.

If you’re having a problem with gnats in houseplants, you might try the below method. We don’t guarantee it will work for you, but it’s worth a shot if you don’t want to buy some gnat-killer pesticide designed to kill bees and other beneficial insects.

Here are some ways to help eliminate gnats and other pests from your plants.

What are Fungus Gnats?

Gnats are tiny flying insects mainly found in moist and humid places. They can be found in the soil, water, and moist and rotting leaves. They are tiny and challenging to see, so if you want to get rid of them from the houseplants, you need to try some effective methods. Gnats are not harmful to humans, but they may cause diseases to plants. 

How do you identify the fungus gnats?

There are two types of fungus gnats.

Male: They look like ants with black and red color.

Female: Their body is round, with white spots on their body.

They can cause a lot of problems.

How do gnats affect houseplants?

Gnats can attack the houseplants in two ways:

● They can feed on plant leaves and can leave a sticky substance.

● They can bite the roots of the plant and can damage the plant’s roots.

What Causes Fungus Gnats?

These tiny insects (caterpillars) are attracted to decaying parts of plants which is why they like to attack rotting plants such as your orchids. Sometimes they also damage plants but are only interested in feeding on the plant parts that have not yet decomposed.

You might find it challenging to identify pests as they look almost like your own plant, but don’t fret because many techniques can help you differentiate between a pest and a good friend.

Gnats are a nuisance to gardeners, and if they have access to a source of potting soil that is not of high quality, it cannot be easy to eliminate them. So try to find the best quality potting soil you can, and don’t let the fact that they like to hide in pots of dirt in your yard get in the way of the excellent soil.

Easy Ways To Get Rid Of Gnats In Houseplants

The gnats are the most common insects in the houseplants. They are tiny in size, but they are dangerous because they can destroy your plants if left unchecked.

I don’t want to suggest so many tips that will confuse you, so here I will give some practical tips to get rid of gnats in houseplants. You need to use natural methods to get rid of gnats from the houseplants. Here are the practical ways that you can try:

Use traps

You can use many traps to prevent these insects from invading your garden. The most effective trap has strong suction, but make sure that it is not too strong or may harm the plant.

These traps are easy to use, and you don’t need any special knowledge to create them. You can make them with some things that you can find in your kitchen. You can use cotton balls, old socks, rubber bands, toothpicks, and straws.

Make a small hole on the side of the trap to suck the insects into it. Make sure that the hole is big enough for the insect to enter, and you can also put a little bit of sugar on the trap to attract these insects.

Establish an appropriate watering routine

Establishing an appropriate watering routine will help kill off any eggs or larvae in the soil. It will also prevent fungus gnats from moving in in the future. Always check to ensure the top few inches of soil are dry before watering (for more common houseplants).

Use sticky fly traps

I included my favorite flypaper in this year’s plant lover’s gift guide. You’ll find it under the DIY category. If you need to start with flypaper on a budget, buy the cheapest paper you can find – it’s a good idea to try a variety of brands before you find your favorite one!

The adult fly population has been successfully controlled using yellow flypaper, although a lot of research is still being done on this type of population control. Adult populations are tough to control, and there is even no way of getting rid of their offspring.

Clean the leaves and the dirt

The gnats will only come near the dirty plants. So, you need to clean your leaves and the dirt to prevent them from coming in contact with your plant.

Use natural remedies

You can use natural remedies to get rid of gnats from the plants. But if you use chemical products, it can be harmful to your plants. The natural remedies are adequate for the houseplants, and they won’t harm your plants.

I hope this post was helpful for you guys, I know some of you have already tried these tips, and I am sure you will love the results. I also shared the effective ways to get rid of gnats in houseplants. You can even use these tips to get rid of gnats in the other places of your home.

How do You Get Rid of Gnats Naturally?

You can easily control these insects by using natural remedies and avoid getting irritated. Here are the best five methods to get rid of gnats from your home.

Use sand or gravel to dress the soil

I like to use gravel or sand on top of the soil to keep soil-dwelling pests out of my flower beds and vegetable garden. This is particularly true of soil-dwelling gnat larvae, which can cause damage to plant roots by eating at the base of their host plant.

This method works best for simple, one-dimensional data sets with a single variable that you want to measure.

With vinegar

Vinegar can be a simple way to keep your house flies from congregating around food. It can also help control other pests.

You can easily make a homemade pesticide from vinegar, dish soap, and water. Sprinkle the mixture around the base of the plant where the pest lives. Don’t spray it on the leaves, though. That’ll kill them.

Hydrogen peroxide mix

When it comes to killing off fungus gnats (also called vinegar flies) around your home, you should never resort to using just one ingredient. Using only vinegar will not get the job done as it will not kill all the larvae. The combination of vinegar and hydrogen peroxide will work great, but the best way to use this mixture is to spray it on the soil and water it down.

Just remember: Hydrogen peroxide is harmful to plants. For example, leaving some in a vase of water will make the water more acidic. It may even cause death to some tropical plants. In a test, we found that a few drops of the chemical could kill two-thirds of the plants in less than an hour.

Try a soap and water mixture

I use an insecticide spray and a soapy water mixture to kill any soil-dwelling organisms. I don’t overthink this. I fill a watering can with warm, soapy water and apply it to my plants.

If you’re using regular old tap water, you’ll want to make sure you get well-aerated soil. Watering the soil is a simple way to encourage root growth and keep your plants alive.

Neem oil spray

Neem oil is a natural insecticide you can use to kill and repel various insects from your garden. If you don’t want to spray your garden directly with the oil, you can dilute the oil in water and spray it onto your plants instead. You can also apply neem oil directly to the undersides of leaves or simply rub neem oil into the soil near the base of plants.

Sprinkling cinnamon

I tried sprinkling cinnamon on the soil, and it didn’t seem to do anything. Cinnamon has natural fungicides, so I guess maybe you could sprinkle cinnamon on the soil to protect your crops from disease? I never heard of anyone else using this method, but I think it’s worth trying.

How to Keep Gnats Away from Plants?

Will Fungus Gnats Go Away On Their Own?

No, because the eggs are deposited in the soil and hatch in warm weather. The adults remain, feeding on the nectar of plants.

Use only water in a solution of dish soap water to wash away the insecticide.

Can I Spray Fungus Gnats?

Yes, you can. A good, non-toxic treatment is a 1/2-ounce bottle of water. It is recommended that you fill your sprayer with water before spraying. You will need to spray your infested plants several times daily for up to seven days.

Do Gnats Fly Around The House?

Gnats are flies that look somewhat like tiny mosquitoes. They’re not mosquitoes, but they can bite and be disease carriers. They mostly live on dead plant material. Gnats have a tendency to congregate in stagnant water, which is why they often appear around the home.
