Keep Your Trees Healthy Before Problems Start
Northeast Tree Care provides proactive tree health and disease management to protect your property.
Your trees face constant threats from invasive pests and diseases that can weaken them long before visible symptoms appear. Beech Leaf Disease and White Pine Needle Damage often progress silently, and by the time you notice yellowing foliage or thinning canopies, the damage may already be severe. Early detection through scheduled inspections allows you to treat problems before a tree becomes structurally unsound or dies entirely.
Northeast Tree Care specializes in Plant Health Care rather than reactive removal. Annual inspections catch infestations early, which is often more cost-effective than removing a dead tree later. You receive a detailed assessment of each tree's condition, including soil health, pest pressure, and disease indicators. If treatment is needed, we use targeted methods such as trunk injections that deliver systemic protection directly into the vascular system, ensuring the solution reaches every leaf where pests feed.
Schedule an annual inspection with Northeast Tree Care to stay ahead of disease and protect your landscape investment.
How Trunk Injections Protect Trees From the Inside Out
Northeast Tree Care provides proactive tree health and disease management to protect your property.
Trunk injections use high-pressure equipment to deliver treatment directly into the tree's vascular system, where it is transported throughout the canopy. The solution moves through the sapwood and into the leaves, creating a protective barrier against feeding insects. Unlike soil drenches or sprays, injections work faster and provide more uniform coverage, even in large or mature trees.
After treatment, you will notice that new growth remains healthy and vibrant, and pests that attempt to feed on treated foliage are quickly eliminated. One professional injection can protect a tree for two to three years, reducing the need for repeated applications. The treatment is contained entirely within the tree, so there is no drift onto neighboring plants, no runoff into soil, and no exposure risk to children, pets, or pollinators.
Injections are highly effective for trees of all sizes, even those with low to moderate existing damage. They are also the preferred method for properties near water, where traditional spraying may be restricted within 25 feet of ponds, streams, or wetlands. Weather conditions do not affect the treatment, as the solution is sealed inside the tree and will not wash off during rain.
Common Questions Homeowners Ask Before Booking
Homeowners often want to know how injections work, what pests they target, and how long protection lasts before committing to a treatment plan
What pests can trunk injections protect against?
Trunk injections are effective against Emerald Ash Borer, Browntail Moth, and other leaf-feeding insects that rely on systemic contact with treated foliage. The product circulates through the tree and kills pests when they feed on leaves or needles.
How long does one injection treatment last?
A single trunk injection using emamectin benzoate can protect a tree for two to three years, depending on pest pressure and tree size. You do not need to retreat annually unless a severe infestation is present.
When is the best time to treat for Browntail Moth?
The ideal treatment window is early spring, from April to May, before caterpillars reach peak activity and their toxic hairs become a public health hazard. Treating early prevents rashes and respiratory issues caused by airborne hairs.
Why are injections safer than spraying near water?
Injections deliver the treatment inside the tree's vascular system, so there is no risk of drift or runoff into nearby water sources. This makes them the preferred method for properties within 25 feet of ponds, streams, or wetlands.
How quickly does the treatment start working?
Injections are faster-acting than soil treatments because the solution is delivered directly into the sapwood and reaches the canopy within days. You will see protection against feeding pests almost immediately after uptake is complete.

Emerald Ash Borer can kill a healthy ash tree within two to three years if left untreated, and early intervention is the most reliable way to save mature specimens. Contact Northeast Tree Care to schedule an inspection and discuss whether trunk injections are right for your property.
