Protect Your Hemlocks Before Damage Spreads

If you have hemlock trees on your property in Saco, you may have noticed white cottony masses at the base of the needles or unusual needle drop. These are signs of hemlock woolly adelgid, an invasive insect that feeds on hemlock sap and weakens the tree from the inside out. Left untreated, infestations can kill a mature hemlock in four to ten years, and the damage often begins well before you see significant dieback in Saco's coastal woodlands.

Northeast Tree Care uses tree injections to treat hemlock woolly adelgid reactively when infestations are already present and proactively to prevent new colonies from establishing. The injections deliver systemic insecticide directly into the tree's vascular system, where it circulates through the trunk, branches, and foliage. This method protects the tree without relying on surface sprays that can affect beneficial insects or require repeated applications throughout the season.

If you are noticing white woolly patches or thinning canopy on your hemlocks in Saco, contact Northeast Tree Care to schedule an assessment and discuss treatment timing.

If you have hemlocks showing signs of stress or you want to protect them before an infestation begins, Northeast Tree Care can assess your trees and recommend a treatment plan based on current conditions in Saco.
