What are Bark Beetles?
Trees in the landscape represent someone’s major commitment to remake the area in a very long-term way.

Bark beetles are seen as beneficial to an ecosystem because they typically attack trees that are dead or dying and speed up their decomposition. However, since 2000, bark beetles have grown significantly in number and have spread throughout the U.S. from New Mexico to British Columbia and from California to Long Island. It is widely believed that global warming has had an impact on bark beetle populations as warmer temperatures and shorter winters are not as effective at killing off beetle larvae . As a result, more bark beetles are surviving the winter, reproducing earlier and more frequently, and spreading over larger areas. They are also attacking healthy trees instead of sticking to dead and dying trees.

How do pine beetles get into a tree?
Pine bark beetles are attracted to pine trees by smelling the trees sap. Though most trees will emit small amounts of sap naturally, trees which sustain injury due to man or nature are more likely to get beetle activity. 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.
How much spray should I use on a tree trunk?
Everyone wants to know “how much do I apply per tree”? In general, a tree with a tree trunk 1 foot wide would require about 1 gallon of spray starting up as high as you can reach and letting it “drip” down as you try to cover as much of the sides as possible. Obviously some spray will miss when applied and some will drip to the ground but try to minimize these two events so you get the best coverage. The goal is to cover the bark with enough fluid/mixture to get it damp but no so much that is all running off the tree.
