Repellent for the control of Douglas-Fir and Spruce Beetles
BeetleBlock-MCH is an anti-aggregation pheromone that signals Douglas-Fir Beetles and Spruce Beetles not to visit an area or individual trees. The pheromone repellent is enclosed in a controlled release dispenser that is stapled or nailed to trees during the beetle season.
Control of both Douglas-Fir and Spruce Beetles has been excellent as demonstrated by the USFS and State Foresters. A detailed explanation of MCH and how to use BeetleBlock-MCH can be found here.
