Polyphagous Shot-Hole Borer Information

Polyphagous shot-hole borer (PSHB) is a small beetle native to Southeast Asia that tunnels into the trunks, stems and branches of trees and plants. This beetle is highly invasive and attacks a wide range of plant species, with over 500 documented globally to have been affected.

The Department of Primary Industries and Regional Development (DPIRD) is responding to a detection of this invasive pest. A Quarantine Area covering the entire Perth metro area is in place, with restrictions on the movement of wood, green waste, mulch, live plants and plant material.

PSHB can’t travel far on it’s own but can be moved long distances in infested wood, including firewood. Everyone has an important role to play in preventing the spread of PSHB and protecting WA’s horticulture and regional areas from the impacts of this pest.

Visit DPIRD’s informational stall to learn more about the Quarantine Area, wood movement restrictions and how you can be sure you aren’t accidentally spreading PSHB, as well as the signs and symptoms to look out for and how to report a suspected infestation.
