Any beetle population that might be present at this time would pose a minimal risk of artificial spread. Beetle presence is measured by whether two successive annual core (Level 1) and delimiting surveys (Level 2) have been completed throughout the regulated area with no active signs of or the presence of ALB. Eradication from an area can be declared when four successive annual core and delimiting surveys have been completed and are negative for active signs or the presence of ALB.
