Sometimes a healthy Pine Tree can produce a Pitch Tube that will catch the MPB and kill it before it has a chance to infect the tree.

Mountain Pine Beetle is a ever growing epidemic in Boulder and surrounding areas. Here are some pics of a positive ID of MPB hits. Recommended treatment is to spray 2x a year to help the Pine Trees fight off the beetle.
