Tree bugs can ravage your landscape and leave lasting damage; however, not every insect is damaging some are beneficial to the eco-system. Lady bugs, for example, eat aphids which can often destroy trees and plants. Our Certified Arborists will be able to identify and differentiate Beneficial Insects on your property from damaging insects. Once identified, our Arborists will create a customized plan to provide a solution to your needs.
Treatments For Tree Bugs:
Although plants have natural immune systems, there are many times where Mother Nature cannot heal the tree from tree bugs on your property. In these cases insecticide or other forms of treatment may be applied through injections, spraying, or soil drenches to control insects. Our Certified Arborists are trained, licensed, and experienced in diagnosing and treating insects using our SmartTreat™ Process. Our Arborists will create a customized program to treat the diseases and keep them from reoccurring in the future.
WHAT IS THE SMARTTREAT™ PROCESS?
RTEC’S SmartTreat™ process is a highly effective and environmentally sensitive approach to pest management in our suburban environment. The SmartTreat™ process uses the life cycles of tree bugs and their interaction with the environment to provide more effective pest management solutions all while using fewer chemicals on your property.

Although they may appear individually they are typically seen in groups that feed on the leaves and needles of plant life.
Targets: Spruces, Cedars, and Pine
