Mountain Pine Beetles are Flying: Are Your Pine Trees Protected?


From late July to early August, the Mountain Pine Beetle (MPB) is most active in Colorado. During this peak season, adult beetles emerge from infested trees and seek out healthy pine trees to attack. Current monitoring indicates that beetle activity typically peaks from the last week of July through the first week of August. This is a critical time for homeowners to monitor the health of their pine trees.

If Your Tree Is Already Infested

Unfortunately, if a pine tree is already infested by Mountain Pine Beetles, it cannot be saved. The beetles live beneath the bark, disrupting the tree's ability to transport water and nutrients throughout the tree. Even if the tree remains green for months after the attack, significant damage has already occurred. The fatality rate of trees infested by MPB is 100%.

Proper Disposal of Infested Wood

Responsible disposal of infested wood is crucial to help reduce the spread of MPB. Instead of storing or transporting infested logs where the beetles can continue to develop, bring them to EnviroWorks, Inc., in Morrison or Englewood, Colorado. Our facilities safely process infested wood by chipping it, which destroys the beetles beneath the bark and prevents their spread to other trees. Proper disposal is one of the most effective ways homeowners can help protect Colorado's pine trees.

Prevention Is Key

If your pine trees are healthy and have not yet been infested, preventive treatments are available to protect them from an attack. While preventive sprays are typically applied before beetle flight begins, it's wise to plan these treatments for next season if your trees remain unaffected by Mountain Pine Beetle this season. If you're unsure whether your trees have been attacked, the arborists at Root Tree Service in Centennial, Colorado can inspect your trees and recommend the best course of action.
