Ambrosia Beetles (Scolytinae)
Ambrosia beetles are small wood-boring insects that tunnel into the sapwood of weakened or recently felled trees, carrying fungal spores that feed their larvae. They rarely attack healthy trees but can cause significant damage to stressed or dying specimens in landscapes and orchards. Their entry holes are distinctive small round openings with sawdust tubes. Professional treatment focuses on protecting vulnerable trees and removing infested material.
