Federal Quarantine Map

A federal permit is required for interstate movement. Lumber and logs without bark attached are not regulated. Additional guidance, including the quarantine order and maps, can be found on the right side of this page to help facilitate the lawful movement of plant material under the provisions of the quarantine.

Pine shoot beetle attacks the new pine shoots through its feeding and egg laying, and can cause serious decline of entire stands of trees. Adult beetles are 3 to 5 mm long, or about the size of a match head. They are brown or black and cylindrical. The legless larvae are about 5 mm long with a white body and brown head. There is one generation per year in Maryland with the adults overwintering within the tree and emerging in the early spring.
