■       Greenwood Longicorns are pests of forest trees and freshly felled logs. 

Their damage is often carried over into buildings.  The beetles can emerge from timber up to 6 months after milling; and when the timber containing larvae or paupae is used in buildings and covered with gyprock or other wall linings, they emerge through large oval holes, causing great concern to property owners.  These borers do not reinfest dry timber so no treatment is necessary.
