How to Get Rid of Fruit Flies on Cosmos Plant

Updated: September 7, 2022

Cosmos plants are beautiful and easy to grow, but they can attract fruit flies. These small insects are attracted to the sweet nectar produced by the cosmos flowers, which can be frustrating for gardeners. Fortunately, there are several ways to get rid of fruit flies on cosmos plants.

Identify the Problem

Before you start trying to get rid of fruit flies, it’s important to make sure that’s what you’re dealing with. Fruit flies are small, about 1/8 inch long, and have red eyes. They are attracted to ripe or rotting fruit and vegetables, as well as sweet nectar from flowers like cosmos. If you notice small flies hovering around your cosmos plant, they are likely fruit flies.

Remove Infected Fruits

If you also have fruits or vegetables in your garden, be sure to remove any infected ones. This can help eliminate the source of the problem and prevent it from getting worse. Fruit flies lay their eggs on ripe or rotting fruits and vegetables, so removing them can reduce the number of fruit flies in your garden.

Use Sticky Traps

Sticky traps can be an effective way to catch and kill fruit flies. You can purchase sticky traps at most garden centers or make your own by cutting a piece of yellow cardstock paper into strips and coating them with honey or petroleum jelly. Hang the traps near your cosmos plants to catch the fruit flies.

Use Apple Cider Vinegar

Apple cider vinegar is a natural remedy for getting rid of fruit flies. Place some apple cider vinegar in a jar or bowl, cover it with plastic wrap, and poke a few holes in the top. The fruit flies will be attracted to the vinegar and will get trapped inside the container.

Keep Your Garden Clean

Keeping your garden clean is essential for preventing fruit flies from breeding. Be sure to remove any dead or decaying plant matter, as this can attract fruit flies. Also, be sure to keep your compost pile covered and away from your cosmos plants.

Use Insecticidal Soap

Insecticidal soap is a natural and safe way to get rid of fruit flies on your cosmos plants. You can purchase insecticidal soap at most garden centers or make your own by mixing 2 tablespoons of mild liquid soap with 1 quart of water. Spray the solution directly onto the affected areas of your cosmos plant to kill the fruit flies.
