STEVENSVILLE, Mont. – The Forest Service is tacking verbenone patches to protect campground trees from Mountain Pine Beetles.
Verbenone is a pheromone, or chemical, that tells beetles to go away.
The beetles should be arriving in a couple weeks.
The Forest Service doesn’t have much time to get the word out. Foresters are stapling verbenone patches to Charles Waters’ campground’s beautiful old pine trees.
“It’s like a big no vacancy sign,” said forest service spokesman Tod McKay.
