Treatment Options

Our first recommendation: Spray tree trunks with high dosages of chemicals registered to kill the insects. Certain formulations of Carbaryl (Sevin and others) Permethrin (Astro and others), and Bifenthrin (Onyx) are registered for use to prevent attacks on individual trees. These sprays are applied to living green trees in March - May to kill or deter attacking insects. This preventive spray is quite effective through one growing season. The cost for this is based on the size, location, and number of trees you have. It needs to be applied by a commercial applicator with a high pressure sprayer to reach the tree tops.

Our second recommendation: Inject a chemical directly into the trunk of the tree controlling the insects as they emerge from the tree or feed under the bark.  We only recommend this option if it looks like only a few insects have attacked the tree and the goal is to kill them before they cause more internal damage. The tree would have to be heathy and vigourous to draw the chemical up the tree for this to be effective. Injections would need to be made within 14 days of a successful attack in order to be effective against Mountain Pine Beetle. All the other insects have a larger time period of successful control. This chemical is called Inject-A-Cide and it can be used anytime from early Spring thru October. It needs to be applied by a commercial applicator. The downside to this method is the short 30 day effective time period, unlike the sprays mentioned above that last a whole season.
