Shot-hole borer beetles are bad news for your fruit trees. Unlike other Ambrosia beetles, the Polyphagous Shot Hole Borer seems to attack healthy trees. They develop under the bark and dig tunnels to excavate in and out of the tree. The girdling wounds weaken trees and sometimes even kill them. If not treated at the right time, the trees beyond the damage will have irreversible effects.
The features of invasive shot hole borer attacks and infestations vary among tree types. Repeated fungal attacks can weaken trees, emphasizing the need for professional Shot Hole Borer Beetle Treatment.
