4 Common Pests That Can Harm Your Trees

Mar 28, 2025

Trees are a vital part of our landscapes, providing shade, beauty, and environmental benefits. However, they are also susceptible to various pests that can cause significant damage and even lead to their demise. Understanding these common threats is crucial for maintaining the health and longevity of your trees. At Rolling Green, serving Southern and Northern California, we’ve encountered numerous pest infestations and understand the importance of early detection and effective treatment. With our 25+ years of experience, we provide expert advice and services to protect your trees from these harmful invaders.

  1. Aphids: The Silent Sap Suckers

Aphids are small, soft-bodied insects that feed on the sap of trees, causing damage to leaves, stems, and buds. They can cause leaves to curl, yellow, and drop prematurely. Aphids also secrete honeydew, a sticky substance that can lead to the growth of sooty mold, further damaging the tree.

In California, where diverse tree species thrive, aphids can be a persistent problem. Our team at Rolling Green can identify aphid infestations early and provide effective treatment options, including natural and chemical solutions, to protect your trees. We understand the local ecosystem and can offer eco-friendly approaches when possible.

  1. Bark Beetles: The Internal Destroyers

Bark beetles are small insects that bore into the bark of trees, disrupting the flow of water and nutrients. They can cause significant damage and even kill trees, especially those that are stressed or weakened. Signs of bark beetle infestation include small holes in the bark, sawdust accumulation, and wilting foliage.

California’s diverse climate and forests make it a hotspot for various bark beetle species. Rolling Green’s experts are well-versed in identifying and treating bark beetle infestations. We use targeted treatments to eliminate these pests and protect your trees from further damage. We can also provide tree health assessments to identify trees at risk.

  1. Spider Mites: The Tiny Leaf Devourers

Spider mites are tiny arachnids that feed on the leaves of trees, causing them to become discolored and speckled. They can cause significant damage, especially during hot, dry periods. Spider mites are difficult to see with the naked eye, making early detection challenging.

In California’s dry summers, spider mites can proliferate rapidly. Rolling Green’s professionals are trained to identify spider mite infestations and provide effective control measures. We use safe and effective treatments to protect your trees and prevent further damage.

  1. Caterpillars: The Voracious Leaf Eaters

Caterpillars are the larval stage of moths and butterflies. While some species are harmless, others can cause significant damage to trees by defoliating them. They can strip leaves, weaken trees, and make them more susceptible to disease and other pests.

California’s diverse flora supports a wide range of caterpillar species. Rolling Green can identify harmful caterpillars and provide targeted treatments to protect your trees. We understand the local ecology and can offer integrated pest management strategies that minimize environmental impact.

The Importance of Early Detection and Professional Care

Early detection is crucial for preventing significant damage from tree pests. Regular inspections and monitoring can help identify infestations before they become severe. Professional tree service companies like Rolling Green have the expertise and tools to diagnose and treat pest problems effectively.

Our team of certified professionals is dedicated to protecting the health and beauty of your trees. We offer comprehensive pest management services, including preventative treatments, targeted interventions, and ongoing monitoring. We understand the unique challenges faced by trees in California and provide tailored solutions to ensure their long-term health. We are committed to the health of your local trees.
