Insecticides for Protecting Pine Trees from Mountain Pine Beetle

There are no effective systemic pesticide treatments that will kill mountain pine beetle larvae inside the tree or adults as they emerge from an infested tree. Pesticide treatments are limited to protecting trees from becoming infested. These treatments are applied to the bark to kill the adult beetles as they land on the trunk and begin to burrow into the tree. This method of protection is highly effective and if the pesticides are applied at right time, losses may be as few as one or two trees for every hundred trees treated. However, only trees that are not infested should be treated. If a tree is already infested, pesticide application will not prevent the beetles from emerging and infested other trees.
