What Are The Little Bugs on My Eucalyptus Plant

Eucalyptus plants are widely popular for their aromatic scent and medicinal properties. These plants are native to Australia but have been cultivated worldwide due to their numerous benefits. However, eucalyptus plants are not immune to pests and diseases. One of the most common problems that eucalyptus plant owners encounter is the presence of little bugs on the leaves and stems. In this article, we will discuss the types of bugs that can infest eucalyptus plants and what you can do to get rid of them.

Types of Bugs That Can Infest Eucalyptus Plants

1. Eucalyptus Leaf Beetle

The eucalyptus leaf beetle (Paropsisterna tigrina) is a small beetle that feeds on eucalyptus leaves. The adult beetles are oval-shaped and about 5mm in length. They are usually green or brown, with distinctive tiger stripes on their elytra (wing covers). The larvae of the beetle are dark-colored and covered in spines.

The eucalyptus leaf beetle can cause significant damage to eucalyptus plants, especially young ones. They can defoliate entire trees, leading to stunted growth and reduced vigor. The first signs of infestation are tiny holes in the leaves, which eventually turn into larger patches as the beetles continue to feed.

2. Red Gum Lerp Psyllid

The red gum lerp psyllid (Glycaspis brimblecombei) is a tiny insect that feeds on eucalyptus leaves by sucking sap from the phloem tissues. The insect gets its name from the protective coating it creates around itself called a ‘lerp.’ The lerp is a white, waxy cover that looks like a small bump on the leaf’s surface.

The red gum lerp psyllid can cause severe damage to eucalyptus trees if left unchecked. The insects weaken the tree by reducing its ability to produce food through photosynthesis. The first signs of infestation are the presence of lerps on the leaves and yellowing foliage.

3. Eucalyptus Weevil

The eucalyptus weevil (Gonipterus scutellatus) is a small beetle that feeds on eucalyptus leaves, buds, and shoots. The adult weevils are about 5mm in length and have a distinctive snout that they use to chew through the plant’s tissues. The larvae of the weevil are legless and feed on the roots of eucalyptus plants.

Eucalyptus weevils can cause significant damage to eucalyptus plants, especially young ones. They can defoliate entire trees, leading to stunted growth and reduced vigor. The first signs of infestation are tiny holes in the leaves, which eventually turn into larger patches as the weevils continue to feed.

What You Can Do to Get Rid of Bugs on Your Eucalyptus Plant

If you notice little bugs on your eucalyptus plant, it is essential to act quickly to prevent further damage. Here are some things you can do:

1. Handpick the Bugs

You can manually remove the bugs from your eucalyptus plant by handpicking them off the leaves and stems. This method is suitable for small infestations but may not be effective for larger ones.

2. Use Insecticidal Soap

Insecticidal soap is a natural pesticide that is safe for use on eucalyptus plants. It works by suffocating the bugs, causing them to die. You can buy insecticidal soap from your local garden center or make your own by mixing liquid soap and water.

3. Apply Neem Oil

Neem oil is a natural pesticide derived from the neem tree. It works by disrupting the insect’s hormonal system, preventing them from feeding and reproducing. You can apply neem oil to your eucalyptus plant using a spray bottle or a garden sprayer.

4. Use Chemical Pesticides

Chemical pesticides should be used as a last resort, as they can harm beneficial insects and pollute the environment. If you decide to use chemical pesticides, follow the instructions carefully and wear protective gear, such as gloves and a mask.
