There is an effort underway to save Lambertville’s historic ash trees.

Experts say that eight of the trees are being threatened by Emerald Ash Borer beetles. The insects attack the trees and usually end up killing them.

Monster Tree Service stepped in to help by providing free treatments to keep the beetles away and the trees alive.

“We make a little hole with a drill and we put a plug in there. And as we inject the material and take the syringe back out, it seals it,” says Monster Tree’s Matt Scott. “All the material is contained in the tree and nothing can get in there, either. So, no insects or diseases can infect that.”

Scott says that the insects have been a problem in the area for the last three or four years.
