Developed for Arborists, by Arborists

Our unique method of developing formulations includes a pairing process which matches the active ingredient and application method with the physiology of the plant. Whether you’re looking for insect and disease control, regulate tree growth, or add nutrients to your trees, Arborjet has a product for you.

Why is Tree Protection Important?

Trees provide environmental and economic value annually. Trees increase property values and save on operating costs. Watering, heating, cooling, storm water run-off, and CO2 reduction are just a few of the cost savings we get from trees. Tree removal can cost $500-$1000, per tree, making trunk injection a very cost effective solution. Not to mention, you save the tree!

What is Tree Injection?

Imagine protecting trees from invasive pests without worrying about off-target spray or soil applied pesticides. That’s exactly what Arborjet tree injection offers. Tree injection can be compared to a hospital I.V., we inject our formulations directly into the tree’s vascular system where it distributes throughout the tree.  Moreover, formulations are sealed inside the tree through the use of an Arborplug to achieve fast and effective results. The Tree Injection Advantage

How Does Arborjet Work?

Arborjet equipment injects insecticides, fungicides, and fertilizers directly into the tree. Through the use of Arborplugs, chemicals are sealed inside and quickly distributed throughout the tree’s vascular system, reaching the trunk, branches, and leaves.


Trunk injection is the most effective alternative to spraying or soil applied pesticides for tree insect or pest control. Arborjet’s trunk injection equipment injects formulations directly into the trunk where it is quickly taken up by the vascular system and distributed throughout the tree. With over 10 years of research and development, our trunk injection systems and formulations are proven to give the best results when protecting trees from pests.

Simple & Quick

The Arborjet drill-plug-inject method is easy to learn and application is quick. The Arborjet trunk injection system is a perfect fit for the do-it-yourselfer but is best applied by a professional, especially for more serious problems.


Unlike spraying or soil applications, Arborjet’s system injects directly into the tree, limiting any impact to your family, the applicator, and the environment around you.

Cost Effective

Equipment & formulation costs are much less costly than they use to be. Service providers can offer a program that is valuable to the homeowner and still very profitable for them.
