How to Get Rid of Gnats in Coriander Plant

Updated: December 26, 2022

Coriander is a popular herb that is used in many dishes around the world. However, gnats can be a common problem for coriander plants. These small, flying insects can be a nuisance and can damage your coriander plant. If you are struggling with gnats in your coriander plant, here are some tips on how to get rid of them.

Identify the Type of Gnat

There are several types of gnats that can infest coriander plants, including fungus gnats and fruit flies. The first step in getting rid of gnats is to identify the type of gnat that is infesting your coriander plant. Fungus gnats are small, dark-colored flies that are attracted to moist soil, while fruit flies are attracted to ripening fruit.

Remove Infested Soil

If you have identified fungus gnats as the problem, then removing infested soil is the first step in getting rid of them. Fungus gnats lay their eggs in moist soil, so removing the infested soil will help eliminate their breeding ground. Replace the soil with fresh potting soil and make sure it is well-drained to prevent moisture buildup.

Allow Soil to Dry Out

Gnats thrive in moist environments, so allowing the soil to dry out is an effective way to get rid of them. Water your coriander plant only when the top inch of soil is dry to the touch. This will prevent overwatering and reduce the moisture level in the soil.

Use Sticky Traps

Sticky traps are an effective way to capture adult gnats and prevent them from reproducing. Place yellow sticky traps near your coriander plant to attract and trap adult gnats. These traps can be purchased online or at your local garden store.

Apply Neem Oil

Neem oil is a natural insecticide that can be used to get rid of gnats in coriander plants. Mix neem oil with water according to the instructions on the label and spray it on your plant. Neem oil works by disrupting the life cycle of gnats and preventing them from reproducing.

Keep Your Plant Clean

Keeping your coriander plant clean is important in preventing gnats from infesting it. Remove any dead or decaying leaves from your plant and keep the area around it free from debris. This will eliminate any potential breeding grounds for gnats.
