Vail combats aspen scale infestation

Vail, CO Colorado

VAIL, Colorado – Beginning the week of April 16, the town of Vail will be removing aspen trees from around the Vail Village parking structure and the West Vail roundabout as part of a project to stop the spread of an insect called aspen scale.

This new pest has been infesting aspen trees throughout central Colorado for the past few years. It tends to attack trees planted for landscaping and to date has left native aspen stands unaffected. The insect is considered a non-native species, making its treatment a high priority.

In addition to removing highly impacted trees, the town will be treating mild infestations with an insecticide in an effort to save as many trees as possible.



Town of Vail Landscape Architect Gregg Barrie estimates 150 or more trees on town property are currently infested with aspen scale. Of those, 30 percent will require removal, while 70 percent will be treated with an insecticide. The treatments are taking place in mid-April as a new generation of insects, called crawlers, moves to a clean patch of bark to feed and mate.

As with past infestations, the town will continue to offer a free inspection service for property owners who’d like assistance in evaluating the health of their trees. Consultations with tree care professionals are also recommended.
