Updated: October 8, 2022

Eucalyptus plants are attractive to many gardeners because of their unique foliage and refreshing fragrance. However, these plants are also prone to thrips infestation, which can be detrimental to their growth and overall health. Thrips are small insects that feed on the sap of plants, causing yellowing, curling, and stunted growth. Fortunately, there are several ways to control and get rid of thrips in eucalyptus plants.

Identify the Signs of Thrips Infestation

Before you can effectively get rid of thrips in your eucalyptus plant, you need to identify the signs of an infestation. Here are some of the most common signs:

  • Yellowing or browning of leaves
  • Curling or distortion of leaves
  • Silver or bronze streaks on leaves
  • Black fecal droppings on leaves
  • Stunted growth

If you notice any of these signs, it’s important to act quickly to prevent the infestation from spreading.

Use a Natural Predator

One effective way to get rid of thrips in eucalyptus plants is by introducing natural predators such as ladybugs or lacewings. These insects are known to feed on thrips and can help eliminate the infestation. You can purchase these insects online or at your local garden center and release them near your eucalyptus plant.

Prune Infected Leaves

Another way to get rid of thrips in eucalyptus plants is by pruning infected leaves. This will not only remove the source of the infestation but also help improve the overall appearance of your plant. Be sure to use clean pruning shears and dispose of infected leaves in a sealed bag to prevent further spread of thrips.

Use Insecticidal Soap

Insecticidal soap is a safe and effective way to get rid of thrips in eucalyptus plants. This soap contains fatty acids that penetrate the outer shell of thrips, causing them to dehydrate and die. To use, mix the soap with water according to the package instructions and spray it directly onto the leaves of your plant. Be sure to cover both the tops and bottoms of the leaves for maximum effectiveness.

Apply Neem Oil

Neem oil is another natural remedy that can help get rid of thrips in eucalyptus plants. This oil comes from the seeds of the neem tree and has insecticidal properties that can kill thrips. To use, mix the neem oil with water according to the package instructions and spray it directly onto your plant. Be sure to cover both the tops and bottoms of the leaves.
