Mountain pine beetles, southern pine beetles, ips beetles, and many other insects communicate using pheromones. Verbenone is a synthetic pheromone treatment for high-value pine trees and 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 "verbenone message" that they should look elsewhere for a suitable host.
Verbenone has been used as part of integrated pest management programs (IPM) for more than a decade. Many studies show that areas treated with verbenone, as part of an IPM program, fare significantly better than those that are not protected against bark beetles and similar insects.
Verbenone is environmentally safe and non-toxic to humans, pets, birds, and even the beetles themselves. Always follow the verbenone label instructions provided.
