Zinnias are popular garden plants that produce bright and colorful flowers. However, they are prone to thrips infestation, which can cause damage to the plant and reduce its aesthetic value. Thrips are tiny insects that feed on the plant’s sap and cause discoloration and distortion of leaves and flowers. In this article, we will discuss how to get rid of thrips in zinnia plants.

There are several natural remedies that you can use to control thrips infestation in your zinnia plant. Here are some of them:
Neem oil is a natural insecticide that is effective against thrips. It works by disrupting the insect’s hormonal system, which leads to its death. To use neem oil, mix 1 tablespoon of neem oil with 1 gallon of water and spray it on your zinnia plant. Repeat the process every 10 days until the thrips infestation is gone.
Insecticidal soap is another natural remedy that can help control thrips in zinnia plants. It works by suffocating the insect, which leads to its death. To use insecticidal soap, mix 2 tablespoons of soap with 1 gallon of water and spray it on your zinnia plant. Repeat the process every 7 days until the thrips infestation is gone.
Sticky traps are a non-toxic and effective way to control thrips in zinnia plants. They work by trapping the insects on a sticky surface, which prevents them from feeding on the plant. Hang the traps near your zinnia plant and replace them every 2-3 days to ensure effective control.
If natural remedies do not work or if the thrips infestation is severe, you may need to use chemical remedies to control them. Here are some chemical remedies that you can use:
