MCH Flakes

MCH Flakes Pheromone Repellent for Douglas-Fir and Spruce Beetles

How It Works

MCH bark beetle anti-aggregant flakes (U.S. EPA Product Registration No. 8730–72) contain the active ingredient methyl cyclohexenone, which is effective as an anti-aggregation pheromone against Douglas-fir beetles, spruce beetles, and certain other species.

These flakes provide a very important capability in the fight against Douglas-fir and spruce beetle: namely, the ability to protect high-value trees by allowing rapid and effective aerial treatment of forests or large tree stands not possible with the hand-applied "pouch" or "bubble cap" products.

MCH bark beetle anti-aggregant flakes can also be applied to small to mid–size tree stands or to individual trees using a variety of ground application methods at faster rates than possible with products requiring hand–stapling or nailing.

Benefits of MCH Flakes

  • More tamper and theft resistant than traditional MCH bubble caps.
  • Ideal for use to protect venerable trees at schools, in public parks, along sidewalks, and in areas with a large volume of public and pedestrian traffic.
  • Simple application.
  • Provides virtually the same level of tree and stand protection as traditional MCH pheromone bubble caps.
