Tree bugs can ravage your landscape and leave lasting damage. This quickly brings up questions like, “Are tree bugs dangerous?” “How do I get rid of tree bugs?”
Not every tree bug is harmful, and some are even beneficial to the ecosystem. Ladybugs, for example, eat aphids which can often destroy trees and plants. Our Certified Arborists will be able to identify and differentiate beneficial insects from harmful pests. Once identified, our Certified Arborists will create a customized plan to provide a solution to your needs.
Treatments For Tree Bugs:
Tree bug and pest infestations can quickly demolish a landscape and return year after year if they are not taken care of properly. Certified Arborists have the training, licenses, and experience in understanding, diagnosing, and treating for pest infestations. Depending on the situation, they may use insecticide, injections, spraying, or soil drenches to control insects.

Aphids:
