What Is the Value of MCH Bubble Cap?
MCH, an anti-aggregation pheromone, deters Douglas-fir beetle and spruce beetle from attacking Douglas-fir trees and spruce trees, respectively. Application of MCH Bubble Cap to Douglas-fir trees and spruce trees deters Douglas-fir beetle and spruce beetle from attacking and killing these trees. Application of MCH Bubble Cap to fallen trees and stumps deters the beetles from infesting these preferred host materials and thereby prevents beetle populations from increasing to levels that threaten healthy trees. No other pest control products are currently registered for use against either Douglas-fir beetle or spruce beetle to protect trees from attack.
