Pine beetles that have devastated large portions of Colorado’s forests may be flying earlier than usual, according to a retired Colorado State Forest Service entomologist.

Typically, the pine beetle emerges from Colorado’s lodgepole pine forests in mid- to late July and from ponderosa pines on or around Aug. 10, said Dave Leatherman, a retired CSFS entomologist.

This year, Leatherman said he has seen adult beetles emerge earlier after surveying lodgepole and ponderosa pines northwest of Fort Collins in late May, according to a CSU press release.

Landowners may still have time to protect their trees from the beetles, said Sky Stephens, a CSFS forest entomologist in the release. Preventative chemical and pheromone treatments can be applied to non-infested trees.

People should first contact their local CSFS district office before applying any products, Stephens said in the release. The CSFS recommends using licensed pesticide applicators to apply chemical products.
Before application of a treatment, however, it’s important to make sure the tree is not already infested, Stephens said, as there is no effective treatment for those already affected by the mountain pine beetle.

To contact the CSFS, call 970-491-6303 or visit in person at 3843 LaPorte Ave.
