Prevention and Treatment

Since the Emerald Ash Borer was first discovered in the United States in 2002, it has killed tens of millions of ash trees. Because a tree can die within two to four years from the initial infestation, prevention is the priority in at-risk areas in New Jersey and surrounding states. The emerald ash borer larvae damage ash trees by tunneling through the bark, destroying the tree’s tissues, which are responsible for carrying water and nutrients to the leaves and roots.  The sooner EAB infestation is detected and treated, the greater the chance of saving the tree and preventing the infestation to other trees nearby. At Z Tree Experts, our experienced team will inspect all ash trees for early signs of EAB infestation. We use a prevention process that includes drilling holes in the root of the tree, and injecting imicide into the tree. This allows the imicide to be distributed throughout the entire tree, and prevent Emerald Ash Borers from causing damage.

What is the Emerald Ash Borer?

The Emerald Ash Borer (EAB) is a borer originally from Asia and was first discovered in the United States in 2002, and in New Jersey in 2014. It is suspected that the EAB likely came to North America in wood packing material from Asia, and has since killed tens of millions of trees throughout 26 states in the Northeast and Midwest US. The EAB moves quickly- When a tree in New Jersey is infested with EAB, it usually dies within two to four years. Utilizing preventative methods against an EAB infestation is the key to ensuring the safety of your trees.
