Dusty Miller is a beautiful plant with silver-gray foliage that adds a touch of elegance to any garden. However, it’s not uncommon for these plants to attract gnats. Gnats can be a nuisance, especially if you’re trying to enjoy your garden. Fortunately, there are several ways to get rid of gnats in your Dusty Miller plant.

Identify the Type of Gnat

Before you start treating your Dusty Miller plant for gnats, it’s important to identify the type of gnat you’re dealing with. There are several types of gnats that are commonly found in gardens, including fungus gnats, fruit flies, and drain flies.

Fungus gnats are small black or dark brown flies that are often found near houseplants. Fruit flies are small, red-eyed flies that are attracted to ripe and rotting fruits. Drain flies are tiny flies that are often found near drains and sewage systems.

Once you’ve identified the type of gnat you’re dealing with, you can choose the most effective treatment method.

Remove Infected Soil

If you’ve identified fungus gnats as the culprit, the first step you should take is to remove any infected soil from around your Dusty Miller plant. Fungus gnats thrive in moist soil, so if your plant is overwatered or the soil is too wet, it’s likely that you’ll have a problem with these pests.

Remove any infected soil from around your plant and replace it with fresh, dry soil. This will help to eliminate the moist environment that fungus gnats need to survive.

Use Insecticidal Soap

Insecticidal soap is an effective treatment for many types of gnats. It works by suffocating the insects and preventing them from breathing. Spray the insecticidal soap directly onto your Dusty Miller plant and the surrounding area to kill the gnats.

Keep in mind that insecticidal soap can be harmful to some plants, so make sure to test a small area before applying it to your entire plant.

Use Yellow Sticky Traps

Yellow sticky traps are an effective way to get rid of gnats, especially fruit flies. These traps work by attracting the insects with their bright color and sticky surface, which traps them and prevents them from flying away.

Place yellow sticky traps near your Dusty Miller plant to attract and trap the gnats. Make sure to replace the traps regularly as they become covered in insects.

Keep Your Plant Dry

One of the best ways to prevent gnats from infesting your Dusty Miller plant is to keep it dry. Gnats thrive in moist environments, so if you keep your plant dry, they’ll be less likely to take up residence.

Water your Dusty Miller plant only when the soil is dry to the touch. Avoid overwatering and make sure that the soil has adequate drainage.

Use Diatomaceous Earth

Diatomaceous earth is a natural product that can be used to get rid of many types of insects, including gnats. It works by dehydrating the insects, causing them to die.

Sprinkle diatomaceous earth around your Dusty Miller plant and the surrounding area to kill any gnats that come into contact with it. Keep in mind that diatomaceous earth can also harm beneficial insects, so use it sparingly.
