How to Get Rid of Gnats in Cat Palm Plant

Updated: June 18, 2022

Cat palm plants are a beautiful addition to any home or office. They are easy to care for and can grow up to six feet tall. However, these plants are also prone to gnat infestations, which can be a nuisance. Gnats are small, flying insects that are attracted to moist soil and decaying plant matter. They can quickly multiply and become a problem if left unchecked. Here are some tips on how to get rid of gnats in your cat palm plant.

Identify the Problem

The first step in getting rid of gnats is to identify the problem. Look for small, black flies hovering around your plant or crawling on the soil surface. You may also notice tiny white worms, which are the larvae of the gnats. These worms feed on organic matter in the soil and can cause damage to the roots of your plant.

Remove Infected Soil

To get rid of gnats, you need to remove the source of their food and breeding ground. Start by removing the top layer of soil from your cat palm plant. This will help to remove any eggs or larvae that may be present. Dispose of the soil in a sealed plastic bag, away from your home or office.

Allow Soil to Dry Out

Gnats thrive in moist soil, so allowing the soil to dry out can help to eliminate them. Water your cat palm plant only when the top inch of soil is dry to the touch. Avoid overwatering, as this can create a moist environment that is ideal for gnats.

Use Sticky Traps

Sticky traps can be an effective way to trap and kill adult gnats. These traps are coated with a sticky substance that attracts and traps the insects. Place the traps near your cat palm plant to catch any flying gnats.

Apply Insecticide

If your gnat infestation is severe, you may need to apply an insecticide to eliminate them. Choose an insecticide that is labeled for use on houseplants and follow the instructions carefully. Be sure to keep the plant away from children and pets while the insecticide is being applied.

Keep Your Plant Healthy

Keeping your cat palm plant healthy can help to prevent gnat infestations in the future. Make sure your plant is getting the proper amount of light and water. Fertilize your plant with a balanced fertilizer every three months to promote healthy growth and strong roots.


Gnats can be a pesky problem for cat palm plant owners, but with the right approach, they can be eliminated. By identifying the problem, removing infected soil, allowing soil to dry out, using sticky traps, applying insecticide, and keeping your plant healthy, you can get rid of gnats and enjoy a healthy, beautiful cat palm plant.
