How do mountain pine beetles kill trees?
The mountain pine beetle (Dendroctonus ponderosae) can easily kill pine trees during a heavy breakout, according to Colorado State University. Older trees or trees that are crowded easily become infected. The mountain pine beetle has caused the loss of millions of pine trees throughout the western United States. The beetles tunnel through the tree's bark and create visible holes. Approximately eight to 10 months after the beetles attack the tree, the needles begin to turn yellow. The beetles eat the tree's wood and tunnel deeper in their search for food. Once a tree is infected, there is no method of control to save the tree. It must be cut down and burned. Applications of carbaryl, bifenthrin and permethrin sprays help prevent the beetles from infecting surrounding trees.

Pine bark beetles are attracted to pine trees by smelling the trees sap.

Pruning at inappropriate times (like the summer), mechanical damage by construction crews cutting protective tree bark, lightning, drought, disease or insect damage like that which can occur from termites can all make a tree more susceptible to pine bark beetles. Once a flow of sap is more than normal, the odds that beetles will find the tree are increased.
