Insect & Disease Treatment

Tree Insect & Disease Treatment since 1988

Trees are tall, wide, and extremely strong, yet they can get sick just like us. For the most part if you take care of your trees they will be resilient to pest pressure and diseases. However, healthy trees can still get attacked by insects and become vulnerable to various diseases in the area. The good news is when your tree is sick there are a lot of ways we can treat it and give it the best chance for a full recovery. Just Trees has helped countless Austin residents and businesses save their trees and set up a plan to keep them healthy for the long run.

Tree Insect Treatment in Austin, TX

The best case scenario for treating a tree under insect pressure is to catch it at the earliest stage possible. If you notice a heavy amount of insects on your tree, call your arborist to help identify if it’s a problem that needs to be treated. It all starts with a walkthrough of your property to get an assessment. Depending on the kind of pests we find and the density there are a number of different treatment options we can choose from, with insect spraying being the most common and effective.
