What to do with infested trees

How to treat trees depends on the time of year. The best time to look for new infestations and to treat trees is in late September, October and November! You have many more options at that time. Snow is also less of a factor than it is in the spring.

Trees infested with pine beetle cannot be saved. Cut tree down, remove branches and then:

Treatment options from Sept 30- May 15

  • Solar Treatment for Mountain Pine Beetle
  • Cut to firewood length, split, and burn by April or May, along with more seasoned wood
  • Remove bark (with chain saw, Log Wizard, or draw knife)
  • Chip the entire tree. Gilpin County residents can bring logs to Road and Bridge to be chipped. 4′ length minimum, logs accepted M-W 8 am to 4 pm, you MUST call Road and Bridge (303-582-5004) in advance.
