Management Plan

Executive Summary: since they are attracted to trees suffering with stress, we could prevent stress by deeply watering them and keeping them fertilized on a regular basis. We could also remove and destroy the severely infested trees to keep the infestation from spreading. Sprays that contain pyrethroids are effective at preventing Ambrosia Beetles from entering a tree.
