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

    Must have in the Rockies

    A little bit expensive but things that work usually are. A must-use if you are in an area with pine beetles.

    Satisfied in Boulder CO

    Posted by Rhonda Orenson on 2nd Aug 2021

    We have 12 acres outside of Boulder, CO with tons of pine trees, and therefore pine beetles and associated problems. We are also very concerned about fire danger because it is so dry here for the last few summers. Any prevention possible is a good idea and these are inexpensive to boot. We have put these up for the last 4 years and have convinced our neighbors to do so as well. So far we are all doing noticeably better than areas with no protection or effort placed to eradicate the beetles. If you buy more than the smallest package they will Priority Mail it to you so it will be fast. No UPS nonsense. Strong value and solid idea overall.

    Excellent product and service

    Posted by Monica Morales on 22nd Jul 2021

    We have been purchasing BeetleBLOCK MCH from Eco Green Warehouse for almost 10 years, we do not want to risk our trees and home to beetle kill. Our most recent order arrived in 2 days. We are very pleased with their service and help when we have asked.
