Unfortunately the Spotted Lanternfly isn’t the only insect we need to be concerned about this fall. There is another bug that can damage to your trees — the Ambrosia Beetle.
This is a small beetle that burrows into your tree, often causing lasting damage. A sign that your tree has an Ambrosia Beetle setting up shop are these strange tooth pick-like saw dust strings that pop out of the tree or a collection of what appears to be sawdust at the base of the tree.
Take a look at some of the reference links below to get a better idea of what the Ambrosia Beetle is all about and keep an eye out for these guys in the area.
