Treatment method

Tree injections: treatment that goes where it’s needed

Instead of spraying chemicals into the air, trunk injection places treatment directly inside the tree. It’s targeted, long-lasting and far kinder to everything around it.

Tree Medics injecting a tree with the Arborjet system

Tree Medics uses the Arborjet system for state-of-the-art tree treatments. We prefer injections over sprays because they are better for the environment and we see better long-term results. That said, there is a time and a place for a contact spray, and we always choose the safest, most effective approach for each tree.

How trunk injection works

  • Assess and measureWe confirm the problem, identify the species and measure the trunk to set the right dose.
  • Place small injection sitesSmall, precise sites are placed low on the trunk, in the tree’s active outer layer.
  • Deliver the treatmentThe treatment is introduced directly into the tree’s vascular system.
  • The tree does the restNatural water movement carries the treatment up through the trunk and into the canopy, right where insects feed.

Why we prefer injection

No driftNothing is sprayed into the air, so treatment stays out of neighboring yards, gardens and water.
Safe near sensitive areasA strong option near wells, ponds, playgrounds and homes.
Long-lastingSome treatments, like those for emerald ash borer, protect a tree for two to three years.
Precise dosingEach tree gets a dose matched to its size and condition.

What we treat with injections

Timing matters.

Injections work best when a tree is in leaf and moving water well. We schedule treatments around each pest’s life cycle for the best result.

FAQ

Common questions

Do injections hurt the tree?

Each injection creates a small wound, which is why dosing and placement matter. Done properly by a trained applicator, healthy trees seal these sites as part of their normal growth.

How long does an injection take?

Anywhere from a few minutes to a few hours per tree, depending on its size, the weather and how quickly the tree takes up the treatment.

Is injection safe for pets and kids?

Because treatment goes into the tree instead of onto the ground or into the air, there is far less exposure for people and pets than with spraying.
