Ficus plants are a popular choice for indoor plants because of their lush green leaves and easy maintenance. However, gnats can infest these plants and cause damage to both the plant and your living space. These small black flies hover around the plant and can be a nuisance to deal with. Fortunately, there are several ways you can get rid of gnats in your Ficus plant.

Identify the Problem

Before you start treating your plant, it’s important to identify whether or not you have a gnat infestation. Gnats are small insects that are typically black in color and have long wings. They tend to hover around the soil and the base of the plant. You may also notice small larvae in the soil, which look like tiny white worms.

Gnats are attracted to moist soil, so if you overwater your plant or leave excess water in the saucer, this can create an ideal environment for them to thrive.

Treatment Options

There are several ways you can get rid of gnats in your Ficus plant. Here are some of the most effective methods:

1. Let the Soil Dry Out

Gnats thrive in moist soil, so allowing the soil to dry out is an effective way to get rid of them. Avoid overwatering your plant and make sure there is no standing water in the saucer. You can also remove any dead leaves or debris from the top of the soil as this can attract gnats.

2. Use Sticky Traps

Sticky traps are a simple yet effective way to catch gnats. These traps are coated with a sticky substance that attracts and traps the insects. Place the traps near your Ficus plant and replace them every few days until the infestation is gone.

3. Apply Insecticide

Insecticides can be used to kill adult gnats and their larvae. There are several insecticides available on the market that are safe for indoor use. Follow the instructions carefully and apply the insecticide to the soil as well as the base of the plant.

4. Use Hydrogen Peroxide

Hydrogen peroxide is a natural and effective way to kill gnats in your Ficus plant. Mix one part hydrogen peroxide with four parts water and pour it into the soil. This will kill the larvae and eggs in the soil and prevent future infestations.

5. Repot Your Plant

If your plant is severely infested with gnats, repotting it may be necessary. Remove the plant from its pot and gently shake off as much soil as possible. Rinse the roots with water and replant in fresh, dry soil.

Prevention Tips

Preventing a gnat infestation in your Ficus plant is easier than treating one. Here are some tips to help prevent gnats from infesting your plant:

  • Avoid overwatering your Ficus plant
  • Make sure there is no standing water in the saucer
  • Remove any dead leaves or debris from the top of the soil
  • Keep your plant in a well-ventilated area
  • Use a high-quality, well-draining soil for your plant


Are gnats harmful to my Ficus plant?

Gnats can be harmful to your Ficus plant if left untreated. They can damage the roots and cause stunted growth.

Can I use vinegar to get rid of gnats in my Ficus plant?

While vinegar can be effective at killing adult gnats, it can also harm your plant if used in large amounts. It’s best to use other methods such as letting the soil dry out or using sticky traps.

How often should I replace sticky traps?

You should replace sticky traps every few days or when they become full of gnats.

Can I use insecticide on all types of Ficus plants?

Always read the label on the insecticide to make sure it’s safe for your specific type of Ficus plant. Some plants may be more sensitive to certain chemicals than others.
