How it Works

Pine beetles produce a repellent pheromone in an infested tree when the tree does not have enough food to support invasion of any more beetles.  It is a beetle signal to 'Stay Away', 'No more room'!  This natural pheromone is Verbenone and it has been chemically copied and placed in BeetleBlock-Verbenone packets. 

BeetleBlock-Verbenone FAQs

Our easy to use, controlled release BeetleBlock dispenser is placed on individual trees, or placed in a grid pattern when wanting to protect areas larger than 1/4 acre.  Apply BeetleBlock a few weeks prior to expected beetle flight.  Dispensers will emit repellent for 100 or more days through beetle flight during the summer.  Staple or nail one BeetleBlock dispenser directly to a tree at a height of 6-8ft.

Studies and Testing

Four years of testing by the USDA and Forest Service show that in high beetle populations where beetles were specifically attracted into the test area with attractants, the percentage of trees mass attacked was reduced from an average of 74% on untreated trees, to 18% on BeetleBlock-Verbenone treated trees.

High beetle populations require a higher use rate compared to lower beetle populations.  BeetleBlock-Verbenone may not give the desired control under high beetle populations where more than 60-70% of the trees are expected to be killed during the season.  


BeetleBlock is safe for both users and the environment.  Unlike the insecticides approved for control of Mountain Pine and Ips Beetles, BeetleBlock-Verbenone does not kill bees, beneficial insects, or aquatic organisms.  BeetleBlock can be used around lakes, rivers, and streams and is safe to wildlife.  Application by certified applicator is not required.  Always read the label and follow precautionary statements.
