Green onions, also known as scallions, are a staple in many kitchens. They are easy to grow and add a fresh flavor to many dishes. However, one common problem that can arise when growing green onions is an infestation of fruit flies. These tiny insects are attracted to the moist soil and decaying plant matter around the base of the green onion plant. Not only are they frustrating to deal with, but they can also damage the plant and spread disease. In this article, we will discuss how to get rid of fruit flies on green onion plants.
Identify the Problem
The first step in getting rid of fruit flies on green onion plants is to identify the problem. Fruit flies are small, yellowish-brown insects that are often found near ripe or decaying fruit. They have red eyes and are about 1/8 inch in length. When they infest green onion plants, they are usually found around the base of the plant, where they lay their eggs in the moist soil.
Remove Infested Plants
If you notice that your green onion plant is severely infested with fruit flies, it may be best to remove it entirely. This will prevent the fruit flies from spreading to other plants in your garden. Make sure to dispose of the plant properly, either by burning it or throwing it away in a sealed plastic bag.
Clean Up the Area
Fruit flies are attracted to moist soil and decaying plant matter, so it’s important to keep the area around your green onion plant clean and dry. Remove any dead leaves or debris from the soil surface and make sure the soil is not too wet. If you have standing water in your garden, consider adding drainage to help dry out the soil.
Use Sticky Traps
Sticky traps are a great way to catch fruit flies before they can infest your green onion plant. You can purchase sticky traps online or at your local gardening store. Hang the traps near your green onion plant, and the fruit flies will be attracted to the bright color and stick to the trap.
Use Insecticidal Soap
Insecticidal soap is a non-toxic alternative to chemical pesticides that can be used to control fruit flies on green onion plants. Mix a few drops of liquid soap with water and spray it directly onto the affected area of the plant. The soap will suffocate the fruit flies and prevent them from reproducing.
Maintain Good Hygiene
To prevent future infestations of fruit flies on your green onion plant, it’s important to maintain good hygiene in your garden. Remove any decaying fruit or plant matter from the soil surface, and make sure to water your plants only when necessary. Keep an eye on your green onion plants and remove any dead or damaged leaves as soon as possible.

While chemical pesticides can be effective at controlling fruit flies, they can also harm beneficial insects and be toxic to humans and animals. It’s best to use non-toxic alternatives, such as sticky traps or insecticidal soap.

It’s a good idea to check your green onion plants regularly for signs of fruit fly infestations, especially during warm and humid weather. Keep an eye out for small yellowish-brown insects near the base of the plant and remove any dead or damaged leaves as soon as possible.
