Polyphagous Shot-Hole Borer (PSHB)
Polyphagous shot-hole borer (PSHB) is an invasive pest that poses a significant threat to Western Australia's urban tree canopy, native vegetation, food production and agricultural industries.
PSHB has been detected within the Perth metropolitan area and a quarantine area is in place to help limit its spread. Residents can support efforts to protect local trees and prevent the spread of this pest by remaining vigilant and following current movement restrictions.
Green Waste and Plant Material
All green waste should be securely contained for transport in a covered trailer, truck or skip bin. This helps reduce the risk of spreading PSHB to new areas.
Residents are encouraged to inspect trees and green waste for signs of infestation and report any suspected detections.
