Mountain Pine Beetle
Mountain Pine Beetle (Dendroctonus ponderosae; MPB) are bark beetles native to Colorado that will infest pine trees. MPB is always present in our forest at some level; we tend to notice them when they increase in number and begin killing trees.
What to look for...
What to do if you find MPB in your tree...
If you find a tree with indications of beetle infestation such as frass, it should be removed. Removal should include all of the tree material. To prevent the spread of beetle, the tree should be taken offsite and treated properly. Proper treatment includes whole tree chipping, burning, debarking, or disposal in an area free from other pine trees such as an urban dump site.
A tree that has MPB infestation cannot be saved. it should be removed to prevent further spread.
- Hire a certified arborist to preventatively spray non-infested trees
- Maintain a healthy forest density
- Post pheromone packets onto non-infested trees
