I thought mountain pine beetles weren in the Denver area?
We have seen mountain pine beetle infestations from Boulder to Castle Rock. USDA scientists have projected that by 2012, any community on the Front Range with pine trees will be effected. That is why we are doing preventive spraying now. Currently, areas such as Castle Pines, Pinery, Parker, Boulder and parts of Denver are the most vulnerable but short of a chemical cure that kills off infestations, mountain pine beetle is a part of the Front Range arboriculture.
