Is spraying your trees worth the money, and beneficial for removing pests. Or are there better solutions.
You cannot kill all insects on a tree just by spraying it. Spraying only affects insects actively exposed to the treatment on the outer leaves, branches, or bark. It completely misses bugs hidden under leaves, borers inside the wood, and pests living in the surrounding soil.
Biological Limits of Sprays
* Systemic vs. Contact: Standard sprays usually require direct contact to smother eggs or soft bodies. Systemic insecticides are absorbed by the roots and travel through the tree to kill pests that feed on the foliage.
* Life Cycles: A single spray rarely kills eggs, meaning newly hatched pests will emerge later.
