No need to spray Beetles

City and State Foresters are now saying that there is no need to continue to spray for pine beetles. Click here to view recent article in the Wyoming Tribune Eagle. The reasons for the lower population of beetles is speculative. Some believe it could simply be because the beetles have done such a good job of killing pine trees, that there aren’t many susceptible pines left for them to sustain a high population. The damage from pine beetles has been more severe in Cheyenne than in the other front range communities. However, some of the worst pine beetle damage can be found in Colorado’s Roosevelt National Forest in Larimer County.

The good news is for now, homeowners can save a lot of money by not having to spray their trees. In the meantime, foresters in cities up and down the Front Range are weary about a new severe threat: the Emerald Ash Borer, which has recently taken up residence in Boulder County. The emerald ash borer has been marching across the US from the East to the West and Colorado is now the furthest west infestation. The emerald ash borer has already caused tens of millions of dollars of damage to many eastern states as a result of trees loss in landscapes, urban forests, and woodlots, and this cost is increasing at an exponential rate. In addition, the cost of removing dead and dying ash has overwhelmed eastern state’s municipal budgets in affected counties.

If the emerald ash borer is found in Cheyenne, we will have to crank up the spraying again to save our trees. The Ash tree is the most predominant deciduous tree in Cheyenne and this pest could forever change our urban forest.
