How Tree Injection and Soil Injection Methods Improve Pest Control
For more challenging infestations, tree injection and soil injection stand out as powerful alternatives to standard surface sprays or drenching. The tree injection method introduces the active ingredient directly into the trunk, which then moves through the tree’s vascular system to all tissues, quickly knocking down internal pests like emerald ash borer . Soil injection, meanwhile, places insecticide within the root zone, ensuring far more direct and sustained control for pests affecting roots and the base of the tree.
These approaches minimize environmental exposure and reduce the likelihood of non-target impacts common with broadcast sprays. Leading brands, such as Rainbow Treecare, have elevated the industry standard by offering specialized equipment for both trunk and root injections, giving tree owners faster results and superior plant growth protection.
