Insect Management
Trees are living organisms that, especially in urban environments, are vulnerable to a variety of insect pressures. While many insects—such as pollinators and decomposers—play important roles in tree ecosystems, others like aphids, borers, and scale can cause significant stress or decline if not properly managed. Urban trees often face added challenges like compacted soil, limited root space, and heat stress, which can make them more susceptible to insect infestations. Our approach focuses on proactive, balanced care to help trees thrive in these demanding conditions.
Insects Are a Natural Part of Tree Ecosystems
Not all insects are harmful. Pollinators like bees and butterflies aid in reproduction, while decomposers like beetles help recycle nutrients. But harmful insects feed on leaves, bark, or sap, weakening trees and leaving them vulnerable to environmental stress and disease. Knowing the difference is key to responsible and effective management.
How We Identify and Manage Tree Pests
Our ISA Certified Arborists are trained to recognize early signs of insect infestations, including:
- Discolored, curled, or stunted leaves
- Bark damage or exit holes
- Thinning canopy or branch dieback
Early intervention is critical. Treatments range from trunk sprays and soil drenches to targeted systemic injections, depending on the insect and severity of the issue.
Common Insects Found in the DFW Area
Insect | Tree Hosts | Treatment Options |
---|---|---|
Aphids | Crape Myrtle, Elm, Oak, Pecan | Trunk spray (therapeutic), soil drench (preventative) |
Borers (multiple species) | Various species | Systemic soil or trunk applications |
Hackberry Caterpillar | Hackberry | Monitoring only; typically no treatment |
Emerald Ash Borer (EAB) | Ash | Trunk injection with Emamectin Benzoate ( e.g., Mectinite) |
Important Notice:
Emerald Ash Borer has been confirmed in Dallas, Tarrant, Denton, and surrounding counties. Without preventative treatment, all ash trees are at risk of death. Learn more about EAB.
Integrated Pest Management (IPM)
We follow Integrated Pest Management (IPM) strategies that reduce harmful insect pressure while protecting beneficial organisms and minimizing environmental impact. In urban settings, trees are exposed to added stressors—such as compacted soils, heat islands, limited rooting space, poor drainage, and mechanical damage from construction or vehicles. These conditions weaken a tree’s natural defenses, making them more vulnerable to insect infestations.
To address these challenges, we incorporate holistic tree care as a foundational part of our insect management strategy. This includes improving soil health through organic amendments, optimizing watering practices, applying mulch to regulate soil temperature and moisture, and performing structural pruning to encourage strong, resilient growth. By supporting the overall health of the tree, we enhance its ability to withstand and recover from insect attacks without relying solely on chemical treatments.
Our IPM approach balances prevention, early detection, and targeted interventions—creating a long-term plan tailored to each tree’s environment, species, and risk factors. The result is healthier urban trees, fewer outbreaks, and a more sustainable landscape.
Licensed and Regulated Tree Care
All of our technicians are TDA-licensed applicators and follow strict Texas Department of Agriculture (TDA) guidelines when applying any pesticides or chemical treatments. We take regulatory compliance and environmental safety seriously to ensure that every treatment is legal, responsible, and effective.

PREVENTATIVE EAB TREATMENT
If there is EAB activity within a few miles of where you live or property you manage we recommend preventative systemic insecticide treatment applied by a licensed TDA tree health care technician. EAB treatment lasts for 2 years and must be applied regularly to protect ash trees from infection.

OAK WILT TREATMENT
As oak wilt is a systemic, vascular disease, the most effective treatments consist of injecting the infected trees with a fungicidal chemical. The only currently recommended fungicide is Alamo®, a formulation of the fungicide propiconazole. The fungicide is administered through holes drilled in the root flare of the infected tree and should only be applied by Texas Department of Agriculture Licensed Applicators.

STRESSED MAGNOLIA | AFTER
This after photo was taken June 27, 2024 of a magnolia tree after receiving multiple interventions to improve its health. In addition to a tree health care plan of a deep root fertilization with Biopack plus and Sea3 applied by our TDA licensed technician the owner also fixed the irrigation and cleared the root flare. The difference in health is beautiful.

FERTILIZATION
Our Tree Health Care Programs are designed to deliver the right nutrients at the right times throughout the year. We use the highest quality soil conditioners and fertilizers that are delivered at critical points throughout the seasons to optimize the growth and health of trees.

DEEP ROOT INJECTION SERVICES
At Texas Tree Surgeons our deep root injection services provides fertilization deep into the soil. Our unique mixtures combine macro- and micro-nutrients, root growth stimulators, soil conditioners, beneficial biotics (both mycorrhizal fungi and rhizobacteria), and organic materials to cultivate the optimum natural growth environment.

ROOT PRUNING POST AIR SPADING
To correct this improperly planted tree our Tree Health Care Technicians air spade to expose the root flare and to prune away girdling roots. You can learn more about how to properly plant a tree here.

GIRDLING ROOTS
This tree was planted too deep and has several girdling roots (roots that circle the tree and do no flare out) that left unmanaged would eventually kill the tree. After air spading our Tree Health Care Technicians are pruning the roots and adjusting the soil around the tree to expose the root flare to improve tree health.

INSPECTING FOR POSSIBLE DECAY
Sometimes issues with a tree aren't clearly visible on the outside so an arborist will need to inspect the interior. An arborist does this by probing with a small knife to see how extensive the decay in a region of a tree is. Arborists are able to use this information along with other signs to determine if there are potential structural issues or possible increased chances for failure.

MEASURING DBH
The best way to approximate the size of a tree is to measure their dbh, (diameter, breast, height). This enables our arborists to estimate the amount needed for Tree Health Care products or pricing for Tree Removal.
