Common Pests That Harm Trees And Shrubs In Central Texas

Central Texas Has Five Categories Of Insects

Have you noticed that the trees and shrubs on your Central Texas property just aren’t looking their best? They may be victim to a pest infestation. Insects are a significant health risk to the large plantings in our area, often preying on trees that have an already weakened immune system. When left untreated, a large pest swarm can prove disastrous, feeding on a tree’s bark, roots, and leaves until the plant eventually dies.

Don’t risk the health and longevity of the vegetation on your Central Texas landscapes. Here’s what you need to know about the five different categories of common insects that can harm the trees and shrubs in our region.



Stipplers like lace bugs and spider mites eat the underside of leaves. While they may not cause significant damage to your plants, their feeding frenzy can lead to leaf drop, leaving bare spots throughout the branches. If you have oaks, arborvitae, and Italian cypress in your yard, your property may find itself on the stippler menu. Look for a bleached, bronzed, or stippled look to your leaves to determine if it’s a stippler issue.


Suckers encompass a multitude of Central Texas pests including aphids and scales. Suckers eat a wide range of tree species such as elm, huckleberry, pecan, crape myrtles, and magnolias. While these bugs also may not cause significant damage, they can ignite twig dieback and cause honeydew and sooty mold to grow on your trees.


Have you noticed missing leaf pieces on your shrubs and trees? You may have a chewer infestation. As their name implies, chewers devour the greenery on your plants, leaving leafy skeletons in their wake. A wide range of caterpillars falls in the chewer category, feeding on juniper, oak, cypress, arborvitae, and several other Central Texas trees. A massive infestation can quickly demolish most of the vegetation on a plant, making fast action crucial to saving a tree as soon as an outbreak is evident.

Gall Makers

Gall makers produce “galls” or abnormal balls or growths on the flowers, roots, branches, and leaves of various Central Texas trees and shrubs. Oak apple gall and hickory nipple gall are two of the most common gall makers found here. While these bumps are unsightly, galls are generally not a health risk to the trees, often causing only aesthetic issues.


Cottonwood, redheaded ash, gum bumelia, and emerald ash are just a few of the borer species that could pose a threat to Central Texas trees. The emerald ash borer is perhaps the most threatening of them all. This pest was transported from China in the 90’s and hasn’t stopped destroying U.S. trees since. No matter what the variety, most borers drill holes in the trunk and barks of a tree, rapidly destroying its health.
