How to Get Rid of Gnats in Dark Mystery Plant

Updated: July 12, 2022

If you have a dark mystery plant that has become the breeding ground for gnats, you know how annoying and frustrating it can be. Gnats are small flies that swarm around your plants, and they reproduce quickly, making it difficult to get rid of them. However, there are ways to control and eliminate these pests from your plant.

In this article, we will explore some effective methods for getting rid of gnats in dark mystery plants.

Identify the Source

Before treating the infestation, it is essential to identify the source of the problem. Gnats usually breed in damp soil or organic matter, so check the soil of your plant for signs of moisture or mold. Overwatering your plant can also cause gnats to flourish. Make sure the soil is allowed to dry out before watering again.

Use Sticky Traps

Sticky traps are an effective way to capture adult gnats. Place yellow sticky traps near your plant to attract and trap the flying insects. These traps serve as a physical barrier that prevents gnats from moving freely around your plant.

Apply Insecticides

Insecticides are chemical solutions that kill insects on contact. They are effective in controlling adult gnats but do not control larvae. Products like neem oil, pyrethrin, or spinosad are commonly used insecticides for gnat control.

When using insecticides, follow the manufacturer’s instructions carefully and wear protective gear, such as gloves and goggles.

Use Hydrogen Peroxide

Hydrogen peroxide is a natural solution that can be used to control gnat infestations. Mix one part hydrogen peroxide with four parts water and pour it into the soil of your plant. The solution will kill the larvae and eggs in the soil, preventing future infestations.

Use Beneficial Nematodes

Beneficial nematodes are microscopic worms that feed on gnat larvae. These nematodes are an eco-friendly and natural solution to control gnat infestations. You can purchase beneficial nematodes from garden supply stores and sprinkle them on the soil of your plant.


Gnats can be a nuisance, but with the right methods, you can control and eliminate them from your dark mystery plant. Sticky traps, insecticides, hydrogen peroxide, and beneficial nematodes are effective solutions for gnat control.
