What are Gnats in Plants?

Before stating anything else, I would like to say that gnats are the most annoying thing that could ever happen to your plant!

As gnats in plants are considered small flies which are 1/8 inches long and they are most commonly found in indoor plants. They can easily be noticed in outdoor plants as well, but loving closed places, they are mostly found indoors, moving around your indoor plants.

By the way, they look like mosquitoes but you shouldn’t worry about biting like mosquitoes, because their job is to destroy plants and not annoy you.

The symptoms are of course shown by the plants and you can easily notice if the plant is dealing with gnats.

How to Kill Gnats in Plants?

Now that you know that your plant has gnats within, the time has come to find out the ways how to kill gnats in your plants, because if they stay there for a pretty long time, they can really harm the plant and quickly cause destroying to it! There are some procedures that should be followed, and I would like to make a division.

These are the ways how you can kill gnats in plants and get rid of them:

Use of Stick Traps

Everybody has an idea about those yellow sticks which are known as fly traps and you have at least used them once in a lifetime. Well, they come in handy here as well! Considering that gnats are basically flies, you can put sticky traps on your plant, on the soil or the leaves, and leave them there. You will notice that whenever a gnat tries to be in contact with the plant, it will be stuck on the traps.

I am well aware that this version may make the plant look a bit weird, but still, it is one of the most natural ways of trapping gnats.

Vinegar and Cinnamon Would Help

Vinegar is another choice for killing gnats in plants, and it is interesting enough how much gnats are attracted to vinegar. They love to see vibrant colors and considering that it would definitely be better if you use a colored vinegar type so that the gnats can come easier to it. Once in contact with vinegar, the gnats will be completely dead.

I also mentioned cinnamon, and even though I don’t quite prefer this method, for some people it has been the best one to use. Cinnamon should be sprinkled on the top of the plant’s soil and since it is known as a fungicide it may help you get rid of the gnats.

Use of Products

As time passes, technology has become an inevitable thing, and you may already know that there are different discoveries regarding flies in general that you can put on your houses and get rid of them. Well, you can get one of those products, and it will do the job properly of gathering gnats around and killing them.

Chemical Use: Hydrogen Peroxide Mix

When I say hydrogen peroxide, you should have in mind that you must not use a straight one as it can harm the plant as well. Instead of a straight one, you can make your own mixture while putting water within. It is a quite strong substance, and if you put water, you will notice that it will deal with the gnats only.
