Pine Beetle Repellent (Verbenone)

Protect your trees from the most destructive forest pest in North America. Contech's Pine Beetle Repellent contains Verbenone, a non-toxic treatment that mimics a pheromone released by the pest when an infested tree is full. University studies show that areas treated with verbenone, as part of an IPM program, fare significantly better than those that are not. Each box includes 2 pheromone pouches.

How It Works
Beetles and other insects communicate using pheromones. Verbenone -- a synthetic pheromone treatment for high value pine trees -- replicates the beetle pheromone, sending a message that the tree is full and that the food supply is insufficient for additional beetles. Arriving beetles receive the "message" that they should look elsewhere for a suitable host.

How To Use
Staple one pheromone pouch 7 feet high on the north face of the tree -- or two pouches, one at 6-feet and one at 12-feet -- just prior to beetle flight season (April to June, depending upon location). Make a second application just prior to peak flight (usually mid-August).
