About Bark Beetles
There are numerous species of bark beetles which attack trees throughout the United States. They are typically small, 3-4 mm long with dark, cylindrical bodies. They are boring beetles which tunnel and feed under the bark within the vascular tissue of the tree. Trees infested with bark beetles will gradually turn brown, defoliate and die. Upon inspection of the trunk, there could be exit holes and/or “pitch tubes” in the bark indicating they have either bored in or out of the bark. Their feeding interrupts the tree’s ability to move water and nutrients. Several species also introduce a fungus into the tree which further inhibits the vascular system.
