The Department of Primary Industries and Regional Development (DPIRD) is asking all Perth residents to keep an eye out for the polyphagous shot-hole borer (PSHB).
The polyphagous shot-hole borer is a wood-boring exotic beetle that excavates tunnels in both stressed and healthy trees. The beetles cultivate fungus in the tunnels as a food source. Infested trees can become unsafe and die within two years. Boxelder maple trees, robinias, coral trees, Moreton Bay and Port Jackson figs, and London plane trees are particularly susceptible.
