If you have noticed tiny flies hovering around your dish garden plants, then you may have a gnat infestation. Gnats can be frustrating to deal with, especially when they start to multiply rapidly. Fortunately, there are simple ways to get rid of gnats in dish garden plants.

Identify the Type of Gnat

Before you begin any treatment, it’s important to identify the type of gnat you are dealing with. There are several species of gnats, including fungus gnats and fruit flies, which can both infest dish garden plants. Fungus gnats typically thrive in moist soil conditions, while fruit flies are attracted to overripe fruits and vegetables.

Dry Out the Soil

Gnats thrive in moist soil, so one of the easiest ways to get rid of them is to dry out the soil. Allow the soil in your dish garden plant to dry out completely before watering it again. This will help kill any larvae or eggs that may be present in the soil.

Change the Soil

If drying out the soil doesn’t work, it may be time to change the soil entirely. Remove the plant from its current pot and gently remove as much soil as possible without damaging the roots. Replace it with fresh, sterilized potting soil.

Use Sticky Traps

Sticky traps are an effective way to capture adult gnats. Simply place a few traps around your dish garden plant and wait for them to become covered in gnats. Replace the traps as needed until there are no more gnats present.

Use Hydrogen Peroxide

Hydrogen peroxide is a natural insecticide that can kill larvae and eggs in the soil. Mix one part hydrogen peroxide with four parts water and water your dish garden plant with the solution. Repeat this process every few days until the gnat infestation is gone.

Use Neem Oil

Neem oil is a natural insecticide that is safe to use on plants. Mix a few drops of neem oil with water and apply it to the soil of your dish garden plant. This will kill any larvae or eggs in the soil and prevent future infestations.

Keep Your Dish Garden Plant Clean

Prevention is key to avoiding gnat infestations in the first place. Keep your dish garden plant clean by removing any dead or decaying plant matter, and avoid overwatering the soil. This will create an environment that is less hospitable to gnats.
