Gopher plants are a popular choice for many gardeners, as they are easy to care for and add a beautiful touch to any landscape. However, one problem that can arise with these plants is the presence of gnats. Gnats are small, flying insects that can quickly become a nuisance in your garden. They thrive in warm, moist environments and are attracted to decaying organic matter. If you are dealing with gnats in your gopher plant, there are several steps you can take to eliminate them and keep them from returning.

Identify the Type of Gnat

Before you can effectively get rid of gnats in your gopher plant, you need to identify the type of gnat you are dealing with. There are several types of gnats that commonly infest plants, including fungus gnats, fruit flies, and phorid flies. Each type of gnat requires a different approach to control.

  • Fungus Gnats: These gnats are attracted to damp soil and feed on decaying organic matter. They lay their eggs in the soil, and the larvae feed on plant roots. Fungus gnats are small (about 1/8 inch long) and have long legs.
  • Fruit Flies: These gnats are attracted to ripe or decaying fruit and vegetables. They are about 1/8 inch long and have red eyes.
  • Phorid Flies: These gnats are attracted to decaying organic matter and prefer wet environments. They are small (about 1/16 inch long) and have a humpbacked appearance.

Remove Decaying Organic Matter

Regardless of the type of gnat you are dealing with, removing any decaying organic matter from your gopher plant is the first step in controlling the infestation. This includes fallen leaves, dead plant material, and any fruit or vegetables that have fallen to the ground. These items provide a breeding ground for gnats and should be removed as soon as possible.

Adjust Watering

Gnats thrive in moist environments, so adjusting your watering habits can help control the infestation. Avoid overwatering your gopher plant, as this can create a damp environment that is ideal for gnats. Instead, water your plant only when the soil is dry to the touch.

Use Sticky Traps

Sticky traps are an effective way to capture adult gnats and prevent them from laying eggs in your gopher plant. These traps are coated with a sticky substance that attracts the gnats, and they become stuck to the trap. Place the traps near your gopher plant to capture any adult gnats that are flying around.

Use Insecticidal Soap

Insecticidal soap is a safe and effective way to control gnats in your gopher plant. This soap is made from natural ingredients and can be applied directly to the plant’s foliage. The soap works by suffocating the gnats, preventing them from breathing.
