The beetle will be flying soon in most parts of the interior Rocky Mountains. Traditionally the stock answer for when the adult beetle start their flight is the second week of July and commencing through late September.
Putting aside the range of dates that have been documented from late May to October, at least in Colorado no one that I’ve spoken with in Estes Park, Evergreen, Red Feather Lakes or the Denver area has seen flight evidence. That will start to change any day though.
The flight is the time to apply mountain pine beetle treatments as they are vulnerable. The adult females search for a new lodgepole, ponderosa, scoth or other types of pines, to inhabit and build a colony. The males follow in a mad dash to meet up with her and impress the groovy mating chirps.
With new data showing that the beetle flight of up to a mile is much shorter than the potential distance a beetle colony can take. According to a new Colorado State Extension article by Bill Ciesla about the presence of the mountain pine beetle in urban areas:
How did the beetles get here (Front Range)? They were likely transported by high winds, which occurred during mid to late August, 2008.
In 2009, Fort Collins City foresters identified over 300 attacked pines. Only 20 of the trees were successfully attacked and are dying.

This summer, Mount Rushmore is one of the most highly targeted areas for beetle prevention. South Dakota doen’t jump to mind as a beetle hotspot, but wind has brought it to the Rushmore area. The federal government has allocated money to spray 700 trees, identify and remove infested green trees as well as clearing out dead tree that have gone red.
In order to stop mountain pine beetle, the methods & tools are good, such as physical & electronic methods, I think the methods can stop beetle’s destroy in forest.
