How to Get Rid of Gnats in Corn Cane Plant

Updated: March 25, 2022

If you are a plant enthusiast, you know how frustrating it can be to deal with pesky insects that invade your beloved plants. Gnats are one of the most common insects that infest indoor and outdoor plants. These tiny, flying insects can be found around the soil, leaves, and stems of plants. If you own a corn cane plant, you might have noticed gnats hovering around it. In this article, we will discuss how to get rid of gnats in corn cane plants.

Identify Gnats in Corn Cane Plant

Before jumping into how to get rid of gnats, it is important to identify them. Gnats are small, dark-colored flies that are usually less than 5mm long. They have long legs and antennae and are often seen hovering around the soil surface of plants. If you notice small, black flies buzzing around your corn cane plant or notice larvae in the soil, it is likely that you have a gnat infestation.

Causes of Gnat Infestations

Gnats thrive in moist environments, making potting soil a perfect breeding ground for them. Overwatering your corn cane plant can lead to an accumulation of moisture in the soil, which attracts gnats. Additionally, if you use organic potting soil, it may contain decomposing organic matter that provides food for gnat larvae.

How to Get Rid of Gnats in Corn Cane Plant

There are several ways to get rid of gnats in corn cane plants:

1. Allow the Soil to Dry Out

One of the simplest ways to get rid of gnats is to allow the soil to dry out completely between watering sessions. This will kill the larvae as they need moist soil to survive.

2. Change the Potting Soil

If your corn cane plant is infested with gnats, changing the potting soil can help. Use a high-quality potting mix that is free from decomposing organic matter.

3. Use Sticky Traps

Sticky traps are an effective way to catch gnats. Place yellow sticky traps near your corn cane plant to catch the adult gnats. You can also use apple cider vinegar traps by placing a small amount of apple cider vinegar in a container and covering it with plastic wrap. Poke holes in the wrap to allow gnats to enter, and they will drown in the vinegar.

4. Apply Neem Oil

Neem oil is an all-natural insecticide that is safe for plants and humans. Mix neem oil with water and spray it on your corn cane plant to kill adult gnats and larvae.

5. Use Hydrogen Peroxide

Hydrogen peroxide is another effective way to get rid of gnats in corn cane plants. Mix one part hydrogen peroxide with four parts water and pour it into the soil. This will kill the larvae and prevent new eggs from hatching.


Are gnats harmful to corn cane plants?

Gnats do not cause any direct harm to corn cane plants, but they can be annoying and unsightly. However, if left unchecked, gnat larvae can damage plant roots, leading to stunted growth.

How often should I water my corn cane plant?

Corn cane plants prefer well-draining soil that is allowed to dry out between watering sessions. Water your plant when the top inch of soil feels dry.

Can I use chemical insecticides to get rid of gnats in my corn cane plant?

While chemical insecticides can be effective at killing gnats, they can also harm beneficial insects and pollute the environment. It is best to use natural methods like neem oil and hydrogen peroxide to get rid of gnats.

In conclusion, gnats can be a nuisance to corn cane plants, but with the right methods, they can be eliminated. By identifying the causes of gnat infestations and using natural remedies like neem oil and hydrogen peroxide, you can keep your corn cane plant healthy and thriving.
